Bitcoin Price Prediction 2021
What is Bitcoin (BTC)? Bitcoin is the first decentralized digital currency. Basically, Bitcoin is a peer-to-peer payment system that is not tied to the economy of any country or to the central bank. All actions to issue new coins, process payments, and create accounts are done by equal, independent network participants. Bitcoin uses cryptographic methods to ensure the functioning and protection of the system, but at the same time, all information about transactions is documented on a virtual ledger called the Bitcoin blockchain, which is accessible for everyone to see. Nowadays Bitcoin is the most famous cryptocurrency in the world and the number one digital currency by market capitalization. by StealthEX
Bitcoin achievements and future plans
The latest most impactful news from around Bitcoin were the following: • Bitcoin halving took place on May 11, 2020. • Bitcoin developers move forward protocol enhancements through soft forks and activating Taproot. • Bitcoin is the most popular cryptocurrency investment for companies. MicroStrategy, a publicly-listed U.S. invested $425 million in Bitcoin. Square reportedly invested 1% of its portfolio into BTC, demonstrating strength in its long-term growth. • According to Chainalysis 11.4M Bitcoin are held as long term investment. • At block height 642,034 on August 3, a billion-dollar transaction took place where it only cost a small amount of 80 cents (0.0008034 BTC at 129.6 sat/vB). • Over $300,000 in bitcoin grants being raised to support open source development and seeing bitcoin out-perform the price of gold by 100% so far this year. There is no official roadmap of the Bitcoin project. But according to the official Twitter of the Bitcoin Core developer – John Newbery, in the near future, the Bitcoin team will focus on the Lightning Network. The Lightning teams working on c-lightning (Blockstream), Eclair (ACINQ), LND (Lightning Labs) and Rust Lightning will continue to develop the protocol.
Blomberg analytics says that Bitcoin’s foundation is firming for further price advances. “Considering normal maturation, about double the time frame from $1,000 to $10,000 would come in around 2025, for Bitcoin to potentially add another zero.”
Mike Novogratz (CEO of crypto merchant bank Galaxy Digital) hopes that BTC will reach $20,000 highs by the end of 2020. “This is the year of Bitcoin and if it doesn’t go up now by the end of the year, I might just hang my spurs.”
An entrepreneur John McAfee has attracted public’s attention with his bizarre Bitcoin price predictions for the year 2020. Twitter, by StealthEX At the beginning of October 2020, McAfee got arrested for tax evasion charges, so the crypto community probably will not see the end of this bet.
Famous derivatives trader and consultant, Tony Vays during an interview with IGTV noted his thoughts for BTC price: “Do we think we go as high as $100,000? I’m not willing to make that statement. For me, I would be happy if the next top was around $45,000, and that can happen quickly.”
Anthony “Pomp” Pompliano
The co-founder of Morgan Creek Digital Assets, Anthony “Pomp” Pompliano is sure that Bitcoin will continue to grow. “You know there are people who debate what the size of the gold market is but let’s just use easy numbers. Let’s say that it’s $8 trillion. That puts Bitcoin at, depending on how many are lost or stolen, $400,000 to $450,000 today. Do you think that Bitcoin is going to be the equivalent of the gold market? I don’t. It’s better. It’s going to capture more market.”
By the beginning of December 2020 BTC price will be $10,271.457 (-9.23%) per coin. TradingBeasts analytics thinks that by end of the year 2021 the maximum BTC price will reach $13,969.59 (+22.51%), while the minimum price could be $9,499.322 (-16.69%) per coin.
Wallet Investor Bitcoin price prediction
According to the Wallet Investor Forecast System, BTC is a good long-term investment. By the end of December 2020 Bitcoin could reach a maximum price of $15,339.20 (+34.51%) while by the end of 2021 its price can be $16,691.80 (+46.38%) per coin. So, is it profitable to invest in Bitcoin? According to Wallet investor forecast, the long-term earning potential can reach +12.47% in one year.
DigitalCoinPrice BTC price prediction
Based on DigitalCoinPrice forecast Bitcoin is a profitable investment.The BTC average price may grow up to $26,263.42 (+130.31%) till the end of December 2020. While by end of the next year the its average price will be around $23,736.09 (+108.15%).

Scaling Reddit Community Points with Arbitrum Rollup: a piece of cake
https://preview.redd.it/b80c05tnb9e51.jpg?width=2550&format=pjpg&auto=webp&s=850282c1a3962466ed44f73886dae1c8872d0f31 Submitted for consideration toThe Great Reddit Scaling Bake-Off Baked by the pastry chefs atOffchain Labs Please send questions or comments to [[email protected] ](mailto:[email protected]) 1. Overview We're excited to submit Arbitrum Rollup for consideration to The Great Reddit Scaling Bake-Off. Arbitrum Rollup is the only Ethereum scaling solution that supports arbitrary smart contracts without compromising on Ethereum's security or adding points of centralization. For Reddit, this means that Arbitrum can not only scale the minting and transfer of Community Points, but it can foster a creative ecosystem built around Reddit Community Points enabling points to be used in a wide variety of third party applications. That's right -- you can have your cake and eat it too! Arbitrum Rollup isn't just Ethereum-style. Its Layer 2 transactions are byte-for-byte identical to Ethereum, which means Ethereum users can continue to use their existing addresses and wallets, and Ethereum developers can continue to use their favorite toolchains and development environments out-of-the-box with Arbitrum. Coupling Arbitrum’s tooling-compatibility with its trustless asset interoperability, Reddit not only can scale but can onboard the entire Ethereum community at no cost by giving them the same experience they already know and love (well, certainly know). To benchmark how Arbitrum can scale Reddit Community Points, we launched the Reddit contracts on an Arbitrum Rollup chain. Since Arbitrum provides full Solidity support, we didn't have to rewrite the Reddit contracts or try to mimic their functionality using an unfamiliar paradigm. Nope, none of that. We launched the Reddit contracts unmodified on Arbitrum Rollup complete with support for minting and distributing points. Like every Arbitrum Rollup chain, the chain included a bridge interface in which users can transfer Community Points or any other asset between the L1 and L2 chains. Arbitrum Rollup chains also support dynamic contract loading, which would allow third-party developers to launch custom ecosystem apps that integrate with Community Points on the very same chain that runs the Reddit contracts. 1.1 Why Ethereum Perhaps the most exciting benefit of distributing Community Points using a blockchain is the ability to seamlessly port points to other applications and use them in a wide variety of contexts. Applications may include simple transfers such as a restaurant that allows Redditors to spend points on drinks. Or it may include complex smart contracts -- such as placing Community Points as a wager for a multiparty game or as collateral in a financial contract. The common denominator between all of the fun uses of Reddit points is that it needs a thriving ecosystem of both users and developers, and the Ethereum blockchain is perhaps the only smart contract platform with significant adoption today. While many Layer 1 blockchains boast lower cost or higher throughput than the Ethereum blockchain, more often than not, these attributes mask the reality of little usage, weaker security, or both. Perhaps another platform with significant usage will rise in the future. But today, Ethereum captures the mindshare of the blockchain community, and for Community Points to provide the most utility, the Ethereum blockchain is the natural choice. 1.2 Why Arbitrum While Ethereum's ecosystem is unmatched, the reality is that fees are high and capacity is too low to support the scale of Reddit Community Points. Enter Arbitrum. Arbitrum Rollup provides all of the ecosystem benefits of Ethereum, but with orders of magnitude more capacity and at a fraction of the cost of native Ethereum smart contracts. And most of all, we don't change the experience from users. They continue to use the same wallets, addresses, languages, and tools. Arbitrum Rollup is not the only solution that can scale payments, but it is the only developed solution that can scale both payments and arbitrary smart contracts trustlessly, which means that third party users can build highly scalable add-on apps that can be used without withdrawing money from the Rollup chain. If you believe that Reddit users will want to use their Community Points in smart contracts--and we believe they will--then it makes the most sense to choose a single scaling solution that can support the entire ecosystem, eliminating friction for users. We view being able to run smart contracts in the same scaling solution as fundamentally critical since if there's significant demand in running smart contracts from Reddit's ecosystem, this would be a load on Ethereum and would itself require a scaling solution. Moreover, having different scaling solutions for the minting/distribution/spending of points and for third party apps would be burdensome for users as they'd have to constantly shuffle their Points back and forth. 2. Arbitrum at a glance Arbitrum Rollup has a unique value proposition as it offers a combination of features that no other scaling solution achieves. Here we highlight its core attributes. Decentralized. Arbitrum Rollup is as decentralized as Ethereum. Unlike some other Layer 2 scaling projects, Arbitrum Rollup doesn't have any centralized components or centralized operators who can censor users or delay transactions. Even in non-custodial systems, centralized components provide a risk as the operators are generally incentivized to increase their profit by extracting rent from users often in ways that severely degrade user experience. Even if centralized operators are altruistic, centralized components are subject to hacking, coercion, and potential liability. Massive Scaling. Arbitrum achieves order of magnitude scaling over Ethereum's L1 smart contracts. Our software currently supports 453 transactions-per-second for basic transactions (at 1616 Ethereum gas per tx). We have a lot of room left to optimize (e.g. aggregating signatures), and over the next several months capacity will increase significantly. As described in detail below, Arbitrum can easily support and surpass Reddit's anticipated initial load, and its capacity will continue to improve as Reddit's capacity needs grow. Low cost. The cost of running Arbitrum Rollup is quite low compared to L1 Ethereum and other scaling solutions such as those based on zero-knowledge proofs. Layer 2 fees are low, fixed, and predictable and should not be overly burdensome for Reddit to cover. Nobody needs to use special equipment or high-end machines. Arbitrum requires validators, which is a permissionless role that can be run on any reasonable on-line machine. Although anybody can act as a validator, in order to protect against a “tragedy of the commons” and make sure reputable validators are participating, we support a notion of “invited validators” that are compensated for their costs. In general, users pay (low) fees to cover the invited validators’ costs, but we imagine that Reddit may cover this cost for its users. See more on the costs and validator options below. Ethereum Developer Experience. Not only does Arbitrum support EVM smart contracts, but the developer experience is identical to that of L1 Ethereum contracts and fully compatible with Ethereum tooling. Developers can port existing Solidity apps or write new ones using their favorite and familiar toolchains (e.g. Truffle, Buidler). There are no new languages or coding paradigms to learn. Ethereum wallet compatibility. Just as in Ethereum, Arbitrum users need only hold keys, but do not have to store any coin history or additional data to protect or access their funds. Since Arbitrum transactions are semantically identical to Ethereum L1 transactions, existing Ethereum users can use their existing Ethereum keys with their existing wallet software such as Metamask. Token interoperability. Users can easily transfer their ETH, ERC-20 and ERC-721 tokens between Ethereum and the Arbitrum Rollup chain. As we explain in detail below, it is possible to mint tokens in L2 that can subsequently be withdrawn and recognized by the L1 token contract. Fast finality. Transactions complete with the same finality time as Ethereum L1 (and it's possible to get faster finality guarantees by trading away trust assumptions; see the Arbitrum Rollup whitepaper for details). Non-custodial. Arbitrum Rollup is a non-custodial scaling solution, so users control their funds/points and neither Reddit nor anyone else can ever access or revoke points held by users. Censorship Resistant. Since it's completely decentralized, and the Arbitrum protocol guarantees progress trustlessly, Arbitrum Rollup is just as censorship-proof as Ethereum. Block explorer. The Arbitrum Rollup block explorer allows users to view and analyze transactions on the Rollup chain. Limitations Although this is a bake-off, we're not going to sugar coat anything. Arbitrum Rollup, like any Optimistic Rollup protocol, does have one limitation, and that's the delay on withdrawals. As for the concrete length of the delay, we've done a good deal of internal modeling and have blogged about this as well. Our current modeling suggests a 3-hour delay is sufficient (but as discussed in the linked post there is a tradeoff space between the length of the challenge period and the size of the validators’ deposit). Note that this doesn't mean that the chain is delayed for three hours. Arbitrum Rollup supports pipelining of execution, which means that validators can keep building new states even while previous ones are “in the pipeline” for confirmation. As the challenge delays expire for each update, a new state will be confirmed (read more about this here). So activity and progress on the chain are not delayed by the challenge period. The only thing that's delayed is the consummation of withdrawals. Recall though that any single honest validator knows immediately (at the speed of L1 finality) which state updates are correct and can guarantee that they will eventually be confirmed, so once a valid withdrawal has been requested on-chain, every honest party knows that the withdrawal will definitely happen. There's a natural place here for a liquidity market in which a validator (or someone who trusts a validator) can provide withdrawal loans for a small interest fee. This is a no-risk business for them as they know which withdrawals will be confirmed (and can force their confirmation trustlessly no matter what anyone else does) but are just waiting for on-chain finality. 3. The recipe: How Arbitrum Rollup works For a description of the technical components of Arbitrum Rollup and how they interact to create a highly scalable protocol with a developer experience that is identical to Ethereum, please refer to the following documents: Arbitrum Rollup Whitepaper Arbitrum academic paper (describes a previous version of Arbitrum) 4. Developer docs and APIs For full details about how to set up and interact with an Arbitrum Rollup chain or validator, please refer to our developer docs, which can be found at https://developer.offchainlabs.com/. Note that the Arbitrum version described on that site is older and will soon be replaced by the version we are entering in Reddit Bake-Off, which is still undergoing internal testing before public release. 5. Who are the validators? As with any Layer 2 protocol, advancing the protocol correctly requires at least one validator (sometimes called block producers) that is honest and available. A natural question is: who are the validators? Recall that the validator set for an Arbitrum chain is open and permissionless; anyone can start or stop validating at will. (A useful analogy is to full nodes on an L1 chain.) But we understand that even though anyone can participate, Reddit may want to guarantee that highly reputable nodes are validating their chain. Reddit may choose to validate the chain themselves and/or hire third-party validators.To this end, we have begun building a marketplace for validator-for-hire services so that dapp developers can outsource validation services to reputable nodes with high up-time. We've announced a partnership in which Chainlink nodes will provide Arbitrum validation services, and we expect to announce more partnerships shortly with other blockchain infrastructure providers. Although there is no requirement that validators are paid, Arbitrum’s economic model tracks validators’ costs (e.g. amount of computation and storage) and can charge small fees on user transactions, using a gas-type system, to cover those costs. Alternatively, a single party such as Reddit can agree to cover the costs of invited validators. 6. Reddit Contract Support Since Arbitrum contracts and transactions are byte-for-byte compatible with Ethereum, supporting the Reddit contracts is as simple as launching them on an Arbitrum chain. Minting. Arbitrum Rollup supports hybrid L1/L2 tokens which can be minted in L2 and then withdrawn onto the L1. An L1 contract at address A can make a special call to the EthBridge which deploys a "buddy contract" to the same address A on an Arbitrum chain. Since it's deployed at the same address, users can know that the L2 contract is the authorized "buddy" of the L1 contract on the Arbitrum chain. For minting, the L1 contract is a standard ERC-20 contract which mints and burns tokens when requested by the L2 contract. It is paired with an ERC-20 contract in L2 which mints tokens based on whatever programmer provided minting facility is desired and burns tokens when they are withdrawn from the rollup chain. Given this base infrastructure, Arbitrum can support any smart contract based method for minting tokens in L2, and indeed we directly support Reddit's signature/claim based minting in L2. Batch minting. What's better than a mint cookie? A whole batch! In addition to supporting Reddit’s current minting/claiming scheme, we built a second minting design, which we believe outperforms the signature/claim system in many scenarios. In the current system, Reddit periodically issues signed statements to users, who then take those statements to the blockchain to claim their tokens. An alternative approach would have Reddit directly submit the list of users/amounts to the blockchain and distribute the tokens to the users without the signature/claim process. To optimize the cost efficiency of this approach, we designed an application-specific compression scheme to minimize the size of the batch distribution list. We analyzed the data from Reddit's previous distributions and found that the data is highly compressible since token amounts are small and repeated, and addresses appear multiple times. Our function groups transactions by size, and replaces previously-seen addresses with a shorter index value. We wrote client code to compress the data, wrote a Solidity decompressing function, and integrated that function into Reddit’s contract running on Arbitrum. When we ran the compression function on the previous Reddit distribution data, we found that we could compress batched minting data down to to 11.8 bytes per minting event (averaged over a 6-month trace of Reddit’s historical token grants)compared with roughly 174 bytes of on-chain data needed for the signature claim approach to minting (roughly 43 for an RLP-encoded null transaction + 65 for Reddit's signature + 65 for the user's signature + roughly 8 for the number of Points) . The relative benefit of the two approaches with respect to on-chain call data cost depends on the percentage of users that will actually claim their tokens on chain. With the above figures, batch minting will be cheaper if roughly 5% of users redeem their claims. We stress that our compression scheme is not Arbitrum-specific and would be beneficial in any general-purpose smart contract platform. 8. Benchmarks and costs In this section, we give the full costs of operating the Reddit contracts on an Arbitrum Rollup chain including the L1 gas costs for the Rollup chain, the costs of computation and storage for the L2 validators as well as the capital lockup requirements for staking. Arbitrum Rollup is still on testnet, so we did not run mainnet benchmarks. Instead, we measured the L1 gas cost and L2 workload for Reddit operations on Arbitrum and calculated the total cost assuming current Ethereum gas prices. As noted below in detail, our measurements do not assume that Arbitrum is consuming the entire capacity of Ethereum. We will present the details of our model now, but for full transparency you can also play around with it yourself and adjust the parameters, by copying the spreadsheet found here. Our cost model is based on measurements of Reddit’s contracts, running unmodified (except for the addition of a batch minting function) on Arbitrum Rollup on top of Ethereum. On the distribution of transactions and frequency of assertions. Reddit's instructions specify the following minimum parameters that submissions should support: Over a 5 day period, your scaling PoC should be able to handle:
100,000 point claims (minting & distributing points)
75,000 one-off points burning
We provide the full costs of operating an Arbitrum Rollup chain with this usage under the assumption that tokens are minted or granted to users in batches, but other transactions are uniformly distributed over the 5 day period. Unlike some other submissions, we do not make unrealistic assumptions that all operations can be submitted in enormous batches. We assume that batch minting is done in batches that use only a few percent on an L1 block’s gas, and that other operations come in evenly over time and are submitted in batches, with one batch every five minutes to keep latency reasonable. (Users are probably already waiting for L1 finality, which takes at least that long to achieve.) We note that assuming that there are only 300,000 transactions that arrive uniformly over the 5 day period will make our benchmark numbers lower, but we believe that this will reflect the true cost of running the system. To see why, say that batches are submitted every five minutes (20 L1 blocks) and there's a fixed overhead of c bytes of calldata per batch, the cost of which will get amortized over all transactions executed in that batch. Assume that each individual transaction adds a marginal cost of t. Lastly assume the capacity of the scaling system is high enough that it can support all of Reddit's 300,000 transactions within a single 20-block batch (i.e. that there is more than c + 300,000*t byes of calldata available in 20 blocks). Consider what happens if c, the per-batch overhead, is large (which it is in some systems, but not in Arbitrum). In the scenario that transactions actually arrive at the system's capacity and each batch is full, then c gets amortized over 300,000 transactions. But if we assume that the system is not running at capacity--and only receives 300,000 transactions arriving uniformly over 5 days-- then each 20-block assertion will contain about 200 transactions, and thus each transaction will pay a nontrivial cost due to c. We are aware that other proposals presented scaling numbers assuming that 300,000 transactions arrived at maximum capacity and was executed in a single mega-transaction, but according to our estimates, for at least one such report, this led to a reported gas price that was 2-3 orders of magnitude lower than it would have been assuming uniform arrival. We make more realistic batching assumptions, and we believe Arbitrum compares well when batch sizes are realistic. Our model. Our cost model includes several sources of cost:
L1 gas costs: This is the cost of posting transactions as calldata on the L1 chain, as well as the overhead associated with each batch of transactions, and the L1 cost of settling transactions in the Arbitrum protocol.
Validator’s staking costs: In normal operation, one validator will need to be staked. The stake is assumed to be 0.2% of the total value of the chain (which is assumed to be $1 per user who is eligible to claim points). The cost of staking is the interest that could be earned on the money if it were not staked.
Validator computation and storage: Every validator must do computation to track the chain’s processing of transactions, and must maintain storage to keep track of the contracts’ EVM storage. The cost of computation and storage are estimated based on measurements, with the dollar cost of resources based on Amazon Web Services pricing.
It’s clear from our modeling that the predominant cost is for L1 calldata. This will probably be true for any plausible rollup-based system. Our model also shows that Arbitrum can scale to workloads much larger than Reddit’s nominal workload, without exhausting L1 or L2 resources. The scaling bottleneck will ultimately be calldata on the L1 chain. We believe that cost could be reduced substantially if necessary by clever encoding of data. (In our design any compression / decompression of L2 transaction calldata would be done by client software and L2 programs, never by an L1 contract.) 9. Status of Arbitrum Rollup Arbitrum Rollup is live on Ethereum testnet. All of the code written to date including everything included in the Reddit demo is open source and permissively licensed under the Apache V2 license. The first testnet version of Arbitrum Rollup was released on testnet in February. Our current internal version, which we used to benchmark the Reddit contracts, will be released soon and will be a major upgrade. Both the Arbitrum design as well as the implementation are heavily audited by independent third parties. The Arbitrum academic paper was published at USENIX Security, a top-tier peer-reviewed academic venue. For the Arbitrum software, we have engaged Trail of Bits for a security audit, which is currently ongoing, and we are committed to have a clean report before launching on Ethereum mainnet. 10. Reddit Universe Arbitrum Rollup Chain The benchmarks described in this document were all measured using the latest internal build of our software. When we release the new software upgrade publicly we will launch a Reddit Universe Arbitrum Rollup chain as a public demo, which will contain the Reddit contracts as well as a Uniswap instance and a Connext Hub, demonstrating how Community Points can be integrated into third party apps. We will also allow members of the public to dynamically launch ecosystem contracts. We at Offchain Labs will cover the validating costs for the Reddit Universe public demo. If the folks at Reddit would like to evaluate our software prior to our public demo, please email us at [email protected] and we'd be more than happy to provide early access. 11. Even more scaling: Arbitrum Sidechains Rollups are an excellent approach to scaling, and we are excited about Arbitrum Rollup which far surpasses Reddit's scaling needs. But looking forward to Reddit's eventual goal of supporting hundreds of millions of users, there will likely come a time when Reddit needs more scaling than any Rollup protocol can provide. While Rollups greatly reduce costs, they don't break the linear barrier. That is, all transactions have an on-chain footprint (because all calldata must be posted on-chain), albeit a far smaller one than on native Ethereum, and the L1 limitations end up being the bottleneck for capacity and cost. Since Ethereum has limited capacity, this linear use of on-chain resources means that costs will eventually increase superlinearly with traffic. The good news is that we at Offchain Labs have a solution in our roadmap that can satisfy this extreme-scaling setting as well: Arbitrum AnyTrust Sidechains. Arbitrum Sidechains are similar to Arbitrum Rollup, but deviate in that they name a permissioned set of validators. When a chain’s validators agree off-chain, they can greatly reduce the on-chain footprint of the protocol and require almost no data to be put on-chain. When validators can't reach unanimous agreement off-chain, the protocol reverts to Arbitrum Rollup. Technically, Arbitrum Sidechains can be viewed as a hybrid between state channels and Rollup, switching back and forth as necessary, and combining the performance and cost that state channels can achieve in the optimistic case, with the robustness of Rollup in other cases. The core technical challenge is how to switch seamlessly between modes and how to guarantee that security is maintained throughout. Arbitrum Sidechains break through this linear barrier, while still maintaining a high level of security and decentralization. Arbitrum Sidechains provide the AnyTrust guarantee, which says that as long as any one validator is honest and available (even if you don't know which one will be), the L2 chain is guaranteed to execute correctly according to its code and guaranteed to make progress. Unlike in a state channel, offchain progress does not require unanimous consent, and liveness is preserved as long as there is a single honest validator. Note that the trust model for Arbitrum Sidechains is much stronger than for typical BFT-style chains which introduce a consensus "voting" protocols among a small permissioned group of validators. BFT-based protocols require a supermajority (more than 2/3) of validators to agree. In Arbitrum Sidechains, by contrast, all you need is a single honest validator to achieve guaranteed correctness and progress. Notice that in Arbitrum adding validators strictly increases security since the AnyTrust guarantee provides correctness as long as any one validator is honest and available. By contrast, in BFT-style protocols, adding nodes can be dangerous as a coalition of dishonest nodes can break the protocol. Like Arbitrum Rollup, the developer and user experiences for Arbitrum Sidechains will be identical to that of Ethereum. Reddit would be able to choose a large and diverse set of validators, and all that they would need to guarantee to break through the scaling barrier is that a single one of them will remain honest. We hope to have Arbitrum Sidechains in production in early 2021, and thus when Reddit reaches the scale that surpasses the capacity of Rollups, Arbitrum Sidechains will be waiting and ready to help. While the idea to switch between channels and Rollup to get the best of both worlds is conceptually simple, getting the details right and making sure that the switch does not introduce any attack vectors is highly non-trivial and has been the subject of years of our research (indeed, we were working on this design for years before the term Rollup was even coined). 12. How Arbitrum compares We include a comparison to several other categories as well as specific projects when appropriate. and explain why we believe that Arbitrum is best suited for Reddit's purposes. We focus our attention on other Ethereum projects. Payment only Rollups. Compared to Arbitrum Rollup, ZK-Rollups and other Rollups that only support token transfers have several disadvantages:
As outlined throughout the proposal, we believe that the entire draw of Ethereum is in its rich smart contracts support which is simply not achievable with today's zero-knowledge proof technology. Indeed, scaling with a ZK-Rollup will add friction to the deployment of smart contracts that interact with Community Points as users will have to withdraw their coins from the ZK-Rollup and transfer them to a smart contract system (like Arbitrum). The community will be best served if Reddit builds on a platform that has built-in, frictionless smart-contract support.
All other Rollup protocols of which we are aware employ a centralized operator. While it's true that users retain custody of their coins, the centralized operator can often profit from censoring, reordering, or delaying transactions. A common misconception is that since they're non-custodial protocols, a centralized sequencer does not pose a risk but this is incorrect as the sequencer can wreak havoc or shake down users for side payments without directly stealing funds.
Sidechain type protocols can eliminate some of these issues, but they are not trustless. Instead, they require trust in some quorum of a committee, often requiring two-third of the committee to be honest, compared to rollup protocols like Arbitrum that require only a single honest party. In addition, not all sidechain type protocols have committees that are diverse, or even non-centralized, in practice.
Plasma-style protocols have a centralized operator and do not support general smart contracts.
13. Concluding Remarks While it's ultimately up to the judges’ palate, we believe that Arbitrum Rollup is the bakeoff choice that Reddit kneads. We far surpass Reddit's specified workload requirement at present, have much room to optimize Arbitrum Rollup in the near term, and have a clear path to get Reddit to hundreds of millions of users. Furthermore, we are the only project that gives developers and users the identical interface as the Ethereum blockchain and is fully interoperable and tooling-compatible, and we do this all without any new trust assumptions or centralized components. But no matter how the cookie crumbles, we're glad to have participated in this bake-off and we thank you for your consideration.

Miners obtain the integrity of the original protocol by providing data storage and / or retrieval. On the contrary, customers pay miners to store or distribute data and retrieve it. Filecoin announced, that there will be more delays before its main network is officially launched. Filecoin developers postponed the release date of their main network to late July to late August 2020. As mentioned in a recent announcement, the Filecoin team said that the initiative completed the first round of the internal protocol security audit. Platform developers claim that the results of the review showed that they need to make several changes to the protocol’s code base before performing the second stage of the software testing process. Created by Protocol Labs, Filecoin was developed using File System (IPFS), which is a peer-to-peer data storage network. Filecoin will allow users to trade storage space in an open and decentralized market. Filecoin developers implemented one of the largest cryptocurrency sales in 2017. They have privately obtained over $ 200 million from professional or accredited investors, including many institutional investors. The main network was slated to launch last month, but in February 2020, the Philly Queen development team delayed the release of the main network between July 15 and July 17, 2020. They claimed that the outbreak of the Coronavirus (COVID-19) in China was the main cause of the delay. The developers now say that they need more time to solve the problems found during a recent codecase audit. The Filecoin team noted the following: “We have drafted a number of protocol changes to ensure that building our major network launch is safe and economically sound.” The project developers will add them to two different implementations of Filecoin (Lotus and go-filecoin) in the coming weeks. Filecoin developers conducted a survey to allow platform community members to cast their votes on three different launch dates for Testnet Phase 2 and mainnet. The team reported that the community gave their votes. Based on the vote results, the Filecoin team announced a “conservative” estimate that the second phase of the network test should begin by May 11, 2020. The main Filecoin network may be launched sometime between July 20 and August 21, 2020. The updates to the project can be found on the Filecoin Road Map. Filecoin developers stated: “This option will make us get the most important protocol changes first, and then implement the rest as protocol updates during testnet.” Filecoin is back down from the final test stage. Another filecoin decentralized storage network provider launched its catalytic test network, the final stage of the storage network test that supports the blockchain. In a blog post on her website, Filecoin said she will postpone the last test round until August. The company also announced a calibration period from July 20 to August 3 to allow miners to test their mining settings and get an idea of how competition conditions affected their rewards. Filecoin had announced earlier last month that the catalytic testnet test would precede its flagship launch. The delay in the final test also means that the company has returned the main launch window between August 31 and September 21. Despite the lack of clear incentives for miners and multiple delays, Filecoin has succeeded in attracting huge interest, especially in China. Investors remained highly speculating on the network’s mining hardware and its premium price. Mining in Filecoin In most blockchain protocols, “miners” are network participants who do the work necessary to promote and maintain the blockchain. To provide these services, miners are compensated in the original cryptocurrency. Mining in Filecoin works completely differently — instead of contributing to computational power, miners contribute storage capacity to use for dealing with customers looking to store data. Filecoin will contain several types of miners: Storage miners responsible for storing files and data on the network. Miners retrieval, responsible for providing quick tubes for file recovery. Miners repair to be carried out. Storage miners are the heart of the network. They earn Filecoin by storing data for clients, and computerizing cipher directories to check storage over time. The probability of earning the reward reward and transaction fees is proportional to the amount of storage that the Miner contributes to the Filecoin network, not the hash power. Retriever miners are the veins of the network. They earn Filecoin by winning bids and mining fees for a specific file, which is determined by the market value of the said file size. Miners bandwidth and recovery / initial transaction response time will determine its ability to close recovery deals on the network. The maximum bandwidth of the recovery miners will determine the total amount of deals that it can enter into. In the current implementation, the focus is mostly on storage miners, who sell storage capacity for FIL.
The current system specifications recommended for running the miner are:
NVIDIA-manufactured GPU (to be expanded).
SSD drive designated as large buffer (512GB +).
Large amount of RAM for data replication account (128GB +)
Compared to the hardware requirements for running a validity checker, these standards are much higher — although they definitely deserve it. Since these will not increase in the presumed future, the money spent on Filecoin mining hardware will provide users with many years of reliable service, and they pay themselves many times. Think of investing as a small business for cloud storage. To launch a model on the current data hosting model, it will cost millions of dollars in infrastructure and logistics to get started. With Filecoin, you can do the same for a few thousand dollars. Proceed to mining Deals are the primary function of the Filecoin network, and it represents an agreement between a client and miners for a “storage” contract. Once the customer decides to have a miner to store based on the available capacity, duration and price required, he secures sufficient funds in a linked portfolio to cover the total cost of the deal. The deal is then published once the mine accepts the storage agreement. By default, all Filecoin miners are set to automatically accept any deal that meets their criteria, although this can be disabled for miners who prefer to organize their deals manually. After the deal is published, the customer prepares the data for storage and then transfers it to the miner. Upon receiving all the data, the miner fills in the data in a sector, closes it, and begins to provide proofs to the chain. Once the first confirmation is obtained, the customer can make sure the data is stored correctly, and the deal has officially started. Throughout the deal, the miner provides continuous proofs to the chain. Clients gradually pay with money they previously closed. If there is missing or late evidence, the miner is punished. More information about this can be found in the Runtime, Cut and Penalties section of this page. At Filecoin, miners earn two different types of rewards for their efforts: storage fees and reward prevention. Storage fees are the fees that customers pay regularly after reaching a deal, in exchange for storing data. This fee is automatically deposited into the withdrawal portfolio associated with miners while they continue to perform their duties over time, and is locked for a short period upon receipt. Block rewards are large sums given to miners calculated on a new block. Unlike storage fees, these rewards do not come from a linked customer; Instead, the new FIL “prints” the network as an inflationary and incentive measure for miners to develop the chain. All active miners on the network have a chance to get a block bonus, their chance to be directly proportional to the amount of storage space that is currently being contributed to the network. Duration of operation, cutting and penalties “Slashing” is a feature found in most blockchain protocols, and is used to punish miners who fail to provide reliable uptime or act maliciously against the network. In Filecoin, miners are susceptible to two different types of cut: storage error cut, unanimously reduce error. Storage Error Reduction is a term used to include a wider range of penalties, including error fees, sector penalties, and termination fees. Miners must pay these penalties if they fail to provide reliability of the sector or decide to leave the network voluntarily. An error fee is a penalty that a miner incurs for each non-working day. Sector punishment: A penalty incurred by a miner of a disrupted sector for which no error was reported before the WindowPoSt inspection. The sector will pay an error fee after the penalty of the sector once the error is discovered. Termination Fee: A penalty that a miner incurs when a sector is voluntary or involuntarily terminated and removed from the network. Cutting consensus error is the penalty that a miner incurs for committing consensus errors. This punishment applies to miners who have acted maliciously against the network consensus function. Filecoin miners Eight of the top 10 Felticoin miners are Chinese investors or companies, according to the blockchain explorer, while more companies are selling cloud mining contracts and distributed file sharing system hardware. CoinDesk’s Wolfe Chao wrote: “China’s craze for Filecoin may have been largely related to the long-standing popularity of crypto mining in the country overall, which is home to about 65% of the computing power on Bitcoin at discretion.” With Filecoin approaching the launch of the mainnet blocknet — after several delays since the $ 200 million increase in 2017 — Chinese investors are once again speculating strongly about network mining devices and their premium prices. Since Protocol Labs, the company behind Filecoin, released its “Test Incentives” program on June 9 that was scheduled to start in a week’s time, more than a dozen Chinese companies have started selling cloud mining contracts and hardware — despite important details such as economics Mining incentives on the main network are still endless. Sales volumes to date for each of these companies can range from half a million to tens of millions of dollars, according to self-reported data on these platforms that CoinDesk has watched and interviews with several mining hardware manufacturers. Filecoin’s goal is to build a distributed storage network with token rewards to spur storage hosting as a way to drive wider adoption. Protocol Labs launched a test network in December 2019. But the tokens mined in the testing environment so far are not representative of the true silicon coin that can be traded when the main network is turned on. Moreover, the mining incentive economics on testnet do not represent how final block rewards will be available on the main network. However, data from Blockecoin’s blocknetin testnet explorers show that eight out of 10 miners with the most effective mining force on testnet are currently Chinese miners. These eight miners have about 15 petabytes (PB) of effective storage mining power, accounting for more than 85% of the total test of 17.9 petable. For the context, 1 petabyte of hard disk storage = 1000 terabytes (terabytes) = 1 million gigabytes (GB). Filecoin craze in China may be closely related to the long-standing popularity of crypt mining in the country overall, which is home to about 65% of the computing power on Bitcoin by estimation. In addition, there has been a lot of hype in China about foreign exchange mining since 2018, as companies promote all types of devices when the network is still in development. “Encryption mining has always been popular in China,” said Andy Tien, co-founder of 1475, one of several mining hardware manufacturers in Philquin supported by prominent Chinese video indicators such as Fenbushi and Hashkey Capital. “Even though the Velikoyen mining process is more technologically sophisticated, the idea of mining using hard drives instead of specialized machines like Bitcoin ASIC may be a lot easier for retailers to understand,” he said. Meanwhile, according to Feixiaohao, a Chinese service comparable to CoinMarketCap, nearly 50 Chinese crypto exchanges are often somewhat unknown with some of the more well-known exchanges including Gate.io and Biki — have listed trading pairs for Filecoin currency contracts for USDT. In bitcoin mining, at the current difficulty level, one segment per second (TH / s) fragmentation rate is expected to generate around 0.000008 BTC within 24 hours. The higher the number of TH / s, the greater the number of bitcoins it should be able to produce proportionately. But in Filecoin, the efficient mining force of miners depends on the amount of data stamped on the hard drive, not the total size of the hard drive. To close data in the hard drive, the Filecoin miner still needs processing power, i.e. CPU or GPU as well as RAM. More powerful processors with improved software can confine data to the hard drive more quickly, so miners can combine more efficient mining energy faster on a given day. As of this stage, there appears to be no transparent way at the network level for retail investors to see how much of the purchased hard disk drive was purchased which actually represents an effective mining force. The U.S.-based Labs Protocol was behind Filecoin’s initial coin offer for 2017, which raised an astonishing $ 200 million. This was in addition to a $ 50 million increase in private investment supported by notable venture capital projects including Sequoia, Anderson Horowitz and Union Square Ventures. CoinDk’s parent company, CoinDk, has also invested in Protocol Labs. After rounds of delay, Protocol Protocols said in September 2019 that a testnet launch would be available around December 2019 and the main network would be rolled out in the first quarter of 2020. The test started as promised, but the main network has been delayed again and is now expected to launch in August 2020. What is Filecoin mining process? Filecoin mainly consists of three parts: the storage market (the chain), the blockecin Filecoin, and the search market (under the chain). Storage and research market in series and series respectively for security and efficiency. For users, the storage frequency is relatively low, and the security requirements are relatively high, so the storage process is placed on the chain. The retrieval frequency is much higher than the storage frequency when there is a certain amount of data. Given the performance problem in processing data on the chain, the retrieval process under the chain is performed. In order to solve the security issue of payment in the retrieval process, Filecoin adopts the micro-payment strategy. In simple terms, the process is to split the document into several copies, and every time the user gets a portion of the data, the corresponding fee is paid. Types of mines corresponding to Filecoin’s two major markets are miners and warehousers, among whom miners are primarily responsible for storing data and block packages, while miners are primarily responsible for data query. After the stable operation of the major Filecoin network in the future, the mining operator will be introduced, who is the main responsible for data maintenance. In the initial release of Filecoin, the request matching mechanism was not implemented in the storage market and retrieval market, but the takeover mechanism was adopted. The three main parts of Filecoin correspond to three processes, namely the stored procedure, retrieval process, packaging and reward process. The following figure shows the simplified process and the income of the miners: The Filecoin mining process is much more complicated, and the important factor in determining the previous mining profit is efficient storage. Effective storage is a key feature that distinguishes Filecoin from other decentralized storage projects. In Filecoin’s EC consensus, effective storage is similar to interest in PoS, which determines the likelihood that a miner will get the right to fill, that is, the proportion of miners effectively stored in the entire network is proportional to final mining revenue. It is also possible to obtain higher effective storage under the same hardware conditions by improving the mining algorithm. However, the current increase in the number of benefits that can be achieved by improving the algorithm is still unknown. It seeks to promote mining using Filecoin Discover Filecoin announced Filecoin Discover — a step to encourage miners to join the Filecoin network. According to the company, Filecoin Discover is “an ever-growing catalog of numerous petabytes of public data covering literature, science, art, and history.” Miners interested in sharing can choose which data sets they want to store, and receive that data on a drive at a cost. In exchange for storing this verified data, miners will earn additional Filecoin above the regular block rewards for storing data. Includes the current catalog of open source data sets; ENCODE, 1000 Genomes, Project Gutenberg, Berkley Self-driving data, more projects, and datasets are added every day. Ian Darrow, Head of Operations at Filecoin, commented on the announcement: “Over 2.5 quintillion bytes of data are created every day. This data includes 294 billion emails, 500 million tweets and 64 billion messages on social media. But it is also climatology reports, disease tracking maps, connected vehicle coordinates and much more. It is extremely important that we maintain data that will serve as the backbone for future research and discovery”. Miners who choose to participate in Filecoin Discover may receive hard drives pre-loaded with verified data, as well as setup and maintenance instructions, depending on the company. The Filecoin team will also host the Slack (fil-Discover-support) channel where miners can learn more. Filecoin got its fair share of obstacles along the way. Last month Filecoin announced a further delay before its main network was officially launched — after years of raising funds. In late July QEBR (OTC: QEBR) announced that it had ceded ownership of two subsidiaries in order to focus all of the company’s resources on building blockchain-based mining operations. The QEBR technology team previously announced that it has proven its system as a Filecoin node valid with CPU, GPU, bandwidth and storage compatibility that meets all IPFS guidelines. The QEBR test system is connected to the main Filecoin blockchain and the already mined filecoin coin has already been tested. “The disclosure of Sheen Boom and Jihye will allow our team to focus only on the upcoming global launch of Filecoin. QEBR branch, Shenzhen DZD Digital Technology Ltd. (“ DZD “), has a strong background in blockchain development, extraction Data, data acquisition, data processing, data technology research. We strongly believe Filecoin has the potential to be a leading blockchain-based cryptocurrency and will make every effort to make QEBR an important player when Mainecoin mainnet will be launched soon”. IPFS and Filecoin Filecoin and IPFS are complementary protocols for storing and sharing data in a decentralized network. While users are not required to use Filecoin and IPFS together, the two combined are working to resolve major failures in the current web infrastructure. IPFS It is an open source protocol that allows users to store and transmit verifiable data with each other. IPFS users insist on data on the network by installing it on their own device, to a third-party cloud service (known as Pinning Services), or through community-oriented systems where a group of individual IPFS users share resources to ensure the content stays live. The lack of an integrated catalytic mechanism is the challenge Filecoin hopes to solve by allowing users to catalyze long-term distributed storage at competitive prices through the storage contract market, while maintaining the efficiency and flexibility that the IPFS network provides. Using IPFS In IPFS, the data is hosted by the required data installation nodes. For data to persist while the user node is offline, users must either rely on their other peers to install their data voluntarily or use a central install service to store data. Peer-to-peer reliance caching data may be a good thing as one or multiple organizations share common files on an internal network, or where strong social contracts can be used to ensure continued hosting and preservation of content in the long run. Most users in an IPFS network use an installation service. Using Filecoin The last option is to install your data in a decentralized storage market, such as Filecoin. In Filecoin’s structure, customers make regular small payments to store data when a certain availability, while miners earn those payments by constantly checking the integrity of this data, storing it, and ensuring its quick recovery. This allows users to motivate Filecoin miners to ensure that their content will be live when it is needed, a distinct advantage of relying only on other network users as required using IPFS alone. Filecoin, powered by IPFS It is important to know that Filecoin is built on top of IPFS. Filecoin aims to be a very integrated and seamless storage market that takes advantage of the basic functions provided by IPFS, they are connected to each other, but can be implemented completely independently of each other. Users do not need to interact with Filecoin in order to use IPFS. Some advantages of sharing Filecoin with IPFS:
Filecoin and IPFS CIDs share hash specifications.
Use libp2p by Filecoin nodes to create secure connections with each other.
Messaging between nodes and cluster propagation is facilitated in Filecoin by libp2p pubsub.
IPLD use for blockchain data structures.
Use Graphsync to transfer data between nodes.
Of all the decentralized storage projects, Filecoin is undoubtedly the most interested, and IPFS has been running stably for two years, fully demonstrating the strength of its core protocol. Filecoin’s ability to obtain market share from traditional central storage depends on end-user experience and storage price. Currently, most Filecoin nodes are posted in the IDC room. Actual deployment and operation costs are not reduced compared to traditional central cloud storage, and the storage process is more complicated. PoRep and PoSt, which has a large number of proofs of unknown operation, are required to cause the actual storage cost to be so, in the early days of the release of Filecoin. The actual cost of storing data may be higher than the cost of central cloud storage, but the initial storage node may reduce the storage price in order to obtain block rewards, which may result in the actual storage price lower than traditional central cloud storage. In the long term, Filecoin still needs to take full advantage of its P2P storage, convert storage devices from specialization to civil use, and improve its algorithms to reduce storage costs without affecting user experience. The storage problem is an important problem to be solved in the blockchain field, so a large number of storage projects were presented at the 19th Web3 Summit. IPFS is an important part of Web3 visibility. Its development will affect the development of Web3 to some extent. Likewise, Web3 development somewhat determines the future of IPFS. Filecoin is an IPFS-based storage class project initiated by IPFS. There is no doubt that he is highly expected. Resources :
Satoshi Nakamoto and Bitcoin are not the only contents in Blockchain, This public chain which is possible modifying global finance trending is the "brave wind and waves" for DeFi
DEFI is extending rapidly, Market value is skyrocketing Every single employee and employer will be shocked by DeFi in Blockchain industry, There has not been a single concept existed can compare to DeFi since block chain technology created ,sparking the fire to spread through the whole block chain industry; Even the founder of Bitcoin and Blockchain Satoshi Nakamoto may not considered that the DeFi trending will exceed Bitcoin. Defi has become the hot topic in Blockchain field since the beginning of 2019;DeFi is the abbreviation for Decentralized Finance, also called open finance, meaning to build decentralized contracts which belongs to open financial system. DeFi is dedicating to provide time free, space free financial activities to all the people, it is what we called decentralized finance. In the current financial systems, all financial services are controlled or adjusted unitedly by centralized finance system, whether the basic function such as deposit and transfer, loan or derivatives transactions are monitored and distributed by centralized financial organizations; DeFi is hoping to build a transparent, addressable and inclusive P2P financial system, minimizing the trust risks, simplifying the transactions payment process, expanding transactions scenarios. DeFi platform has 3 obvious advantages compare to traditional centralized financial systems. 1.Global financial services are applying broadly, allowing everyone getting financial services through internet or smart phones which based on decentralized financial system built-in blockchains, including all the services that current banks organizations provide. 2.Blockchain techniques have high openness characteristic, everyone has the right to access, but nobody has central control right, achieving decentralizing for financial transactions. This point is the original purpose for creating Bitcoin by Satoshi Nakamoto. 3.Cross border will be more convenient and more economical. DeFi is applying the openness trait in Blockchain, avoiding expensive commission during global payment, allowing financial transaction to be more convenient, efficient when minimizing the global transferring cost. Due to these benefits, DeFi is able to occupy first place at the triennial palace examination for block chain industries because of the benefits above. Capitalist is taking up the positions of the fallen and rising to fight one after another; According to the data within block chain fields on Aug 20, the market value for the whole DeFi industry is reaching 11.3billion dollars, which is the signal for passing the top digital currency industry; at the meantime, all the transactions are reaching 429million dollars in all decentralized exchanges; The total loan is reaching 1.5 billion on loan platform; The fixed asset is reaching 6.37billion dollar value for DeFi. For global depressed economic, DeFi industry capital is exceeding most financial industries. When the river rises, the boat floats high. DeFi related project is gaining large profits in the vigorous blockchain exploitation processes. Token price is skyrocketing in DeFi. In two years, Total value DeFi project is rising to 10billion or more, From reasonable perspective, The whole DeFi ecosystem is filling with industry bubble, which is missing the flexibility and grounded projects. Superior projects have something in common. The so-called decentralized finance in DeFi, It consists two parts, which are decentralization and finance, under current circumstances, most projects only achieve “Financial “part in the industry, real decentralizing has not been achieved; For most DeFi projects, the first customized version was not satisfied the marketing expectations, most core functions will need to be updated, so the initial team has to have complete authority to control the projects in order to complete on-time and efficiency updating jobs. This means that all the DeFi projects we see, most projects are controlled by initial creating team. Is controlled DeFi belongs to real DeFi? Does any single project can achieve Finance +decentralized? New born AITD may satisfied blockchain expectation for DEFI, AITD Blockchain new generation foundation public chain at business level is built for “Decentralization +Finance. As the marketing needs increasing annually for finance industries， such as banks, insurances, securities. AITD is following the trend closely, connecting the idea and purpose of DeFi, building a healthy, complete decentralized financial ecosystem; Blockchain DeFi+AITD are extending to new direction for insurance, Trust, pledge, cross region payment. INSURANCE: AITD is innovating the current medical system by integrating insurance easy use scenarios, let’s using medical insurance as an example. AITD blockchain is not only storing digital information prove to blocks, but also achieving message sharing; AITD is able to break through the each steps in insurance process, solving asymmetry problem, allowing information transparency during insurance process for upstream and downstream, achieving value flows; Providing the rewarding mechanism for information provider through information sharing, leading medical system information publicized, breaking through each circulation for Medical- insurance-monitoring, realizing medical electronic and electronic insurance business, achieving insurance business stored in block chain networks through blockchain smart contract, achieving auto insurance verification, intelligent insurance claiming goal. PLEDGE The essence of Pledge is new Smart business, as a new model are becoming the main track for real application, achieving to be the solid foundation for decentralized finance. Financial services should not be built under opacity lonely island. AITD is dedicating to build a finance system that allows everyone visiting as long as internet is available, letting value flow freely; According to the high intelligence and high transparency characteristic, AITD will bring new revolutionized storm to global financial system. The transforming direction for Pledge is open finance, open finance is the future morphology for finance. In the future, we are building highly ecological operating systems, fully integrating the innovative characteristics for front technology, smart business, open organization, digitalized finance, forming delicate business system. TRUST: which is connecting block chain techniques is incorporating innovation, freedom, equality gene.In the premise of Justice and fair, Block chain Trust is containing market value maintaining promotion system, which is able to observe the instant experiences feedbacks for global users through constant updating, promoting changes for products, perfecting uses experiences’ .AITD collective Trust has high transparency rate, requiring real name authentication for loan corporation and investors themselves, processing transparency for each project’s process, dedicating to build a safe, stable, transparent, efficient online and offline platforms for medium , small, micro sized companies which have capital demand and person who has financing needs; innovating the traditional Trust operation mode, practicing facilitating health industry through technology, applying assets operation idea of integrating “smart” ”capital” idea, collaborating with medical fields experts who made great contributions in this field;dedicating to facilitate medical resources, medical research abilities and financial capitals high efficiency integration. CROSS REGION PAYMENTS: Block chain payment techniques are changing “traditional assets flow and information flow” operation modes through the structure and improving traditional high cost transferring, low transparency rate, transactions risks through unique advantages of block chains; AITD has comprehensive, strong international bank card fund collecting products and diverse overseas or local payment receiving methods, which are able to provide global one station online payment solution proposals, allowing users to transfer from anywhere, anytime in the world, enabling merchant to accept different kinds of payments habits, processing exchange rate payment automatically; According to cross region payment scenarios, transferring speed and low cost advantages will be concentrated, platform will collaborate with other platforms within the globe, assisting these platforms which have global community backgrounds to explore payment channels. AITD is incorporating block chain technology and finance to the maximum level. In the original thoughts of Bitcoin from Satoshi Nakamoto，counting on Bitcoin to modify the current financial system mode, allowing real freedom for currency, open sources, decentralization, flowing throughout the society and applying, creating multiple finance scenarios Trust Consensus; AITD+DeFi can achieve things that bitcoin cannot achieve. AITD advantages, self-owned public chain Traditional DeFi projects are distributed on the Ethereum or other networks, traffic jam, low experience rate, high processing fee, internet jam, resisting developer and so on, DeFi projects is suggesting user and developer quitting in Ethereum; AITD which belongs to DeFi is facing the same problems, but AITD team has already found the best solution for this problem. We will explain it later. The current situation that DeFi industries are facing：Although there are too much complaining towards Ethereum, the new or old projects cannot kept without Ethereum. According to the DeFi prime data, in 242 DeFi projects that collecting one time, 197 numbers of DeFi are deployed on Ethereum, EOS and Bitcoin only contain 22 and 23 , DeFi project number is approaching to zero on other public chains, Ethereum is considering as the second leading factor for blockchain industries after Bitcoin, determining the fate of DeFi. Why are DeFi (such as hot Compound, Uniswap) not existing in other public chains? Ultimately, the reason for public chains hardly generate Defi (except Ethereum) due to the following 3 reasons. 1）.Public chain which considers Ethereum as the first public chain, possessing competitive advantages in kinds of assets, total number of assets. 2） Unlike Ethereum, other public chains are not paying much attention to DeFi. they are losing the initiation for following the trend now 3） DeFi Decentralization governing after scaling, causing costs for moving Ethereum to other public chain are hard to estimate. Actually, after DeFi shocked digital currency encrypted market, each public chain is entering DeFi military prepared competition, capital, techniques, human resources are constantly devoting into DeFi; Finally, there is no single public chain exceeding Ethereum or challenging Ethereum.Pulic chain problems are the pain points for the industry. Ether researcher once said that “According to the jam in Ether network, even worse than ICO bubble, this is not exaggerated, During the prosperous period for ICO in 2018, Each transaction processing fee is reaching 5.4 US dollars. However, at the 5:00pm in Aug 13th , this number is skyrocketing and reaching 7.4 us dollars, It is 15 times high comparing to 0.5 US dollars in the previous month;DeFi prosperity on Ether is marketing behavior which is against humanity. Under this circumstances, the trend for searching new public chain is necessary; what is the AITD team solution? The answer is public chain To avoid anti humanity sanction by Ether public chain and also to build a complete, efficient DeFi ecosystem. AITD team is researching and developing self-owned public chain in block chain for three years, providing multi block chain scenarios services to large user groups on AITD block chain. In the future,AITD will provide reliable, safe, convenient blockchain services to users in basic public information search, copyright administration, tracing for certified products, ensuring product security scenarios, achieving multi-path communication which Bitcoin is not able to process; Meanwhile, AITD chain is achieving self-closing loop for ecosystem, extending the spirit of DeFi to insurance, Trust, Pledge,Cross border payment etc in multiple financial scenarios, achieving decentralized finance for real. Current block chain network is independent internet relatively, encountering information island problems; Isolation of the internet is not supporting collaborative operation between each blockchain network. Isolation limit applied fields for the blockchain techniques at maximum level; However, AITD is dedicating to build a strong extensibility block chain networks, when it achieves fast, safe cross chain data visit, it also builds a valuable internet for the whole block chain industry. Valued internet+ Blockchain decentralized finance, AITD have strong ambition, dedicating to provide value of 11.3billion the best application in financial world, we will wait for the expecting result.
How ironic that one day everyone began to hear that they were cryptocurrencies, but everything that referred to them was synonymous with Bitcoin everywhere they talk about it, the strange thing is that more than 10 have passed years since this project started and many continue with blindfolds, we have evolved, revolutionary things have come into our lives, the last decades have come technologies that have changed our paradigms, such as the internet and many more came one of them it's bitcoin. Bitcoin arose from the need for a safe, transparent and reliable money. All this is described by Satoshi Nakamoto in his white paper https://www.bitcoin.org/bitcoin.pdf this is at the hand of all so that we can see and read it and know how its structure is shaped and the purpose it has as a currency. Its operation occurred on January 3, 2009, when the genesis block of the chain was published, which was the first block mined in the network, bitcoin turns out to be for the time a magnificent money for the environment that was growing and its use was not long in Expanding its adoption, Hal Finney was one of the first people to support and contribute with Bitcoin since it was part of one of the first nodes, bitcoin has a maximum number of bitcoins that can be created on the network which is 21 million BTC Being this way it solves the problem of inflation since it is a deflationary currency, this system means that no more can be generated and its value will rise more over time due to the supply and demand that there will be in the market. Every time a transaction is made there will be a number of validators that work to verify that the network is correct, this is through the blockchain is the accounting book where all the transactions made from the genesis block are stored , it is public and we can all see how it works that they do not draw cards up their sleeves, these blocks are mined every 10 minutes with a size of 1 mb approximately 2048 transactions that were made and will be mined by a very important group called miners who solve a mathematical process called proof of work with this will be the final process for your BTC sent will already be in the hands of its recipient. To make a transaction you only need the address to which you want to send BTC or the QR code to be faster and select the amount in your wallet, with this you will only have to pay a commission for the work carried out by the miners that can vary depending on the time with which you want your transaction to be verified or to be mined in the next block of the chain. Today Bitcoin is the most important currency in the entire market with a strong ecosystem and a very large community that grows more for the security it offers, its price when making this post reaches $ 9,342.58 and a market capitalization of 168,004,364,619, $ 45 with which it takes the number 1 spot on the coinmarketCap list. original post.

What is Bitcoin SV (BSV)? Bitcoin SV appeared as a result of the Bitcoin Cash hard fork in November 2018. The idea to create a new cryptocurrency came from entrepreneur Craig Wright. He tried to solve the scalability issue and increased the block size to 128MB. Later Craig Wright announced that he is the real Satoshi Nakamoto and Bitcoin SV is the original Bitcoin. SV stands for Satoshi Vision. by StealthEX Bitcoin SV has the plan for a stable protocol and massive on-chain scaling to become the world’s new money and the global public blockchain for enterprise. Today BSV coin is one of the TOP-10 cryptocurrencies by market capitalization.
In 2019 the project has gone through the following milestones: • Upgraded Quasar protocol and as a result the block size was lifted from 128 MB to 2 GB. • Bitcoin SV handled up to 20,000,000 transactions per day. • Worked on the technical development: Paymail, Nakasendo, Keyring, sCrypt, GearSV, Datapay was launched. • More than 300 development projects, apps were launched for the BSV network. • Celebrated the project’s first birthday.
What to expect in the future?
According to the official roadmap, the Bitcoin SV team will continue working on: • Stability to give enterprises the confidence to create their apps on top of BSV. • Scalability. The developers intend to provide the capacity for BSV to act as the foundation for the entire financial world. • Security and excellent payment experience. The BSV project will concentrate on both measurement and improvement of transactions safety, fast transaction propagation, and miner-configurable fee policies.
In August 2020 BSV crypto may reach a maximum price of $209.095 (+18.60%), while it’s the average price will be around $166.599 per coin (-5.50%). According to TradingBeasts forecasts, the Bitcoin SV price is going to decrease and by the end of 2020, the average BSV price is expected to be $168.674 (-4.33%).

Bitcoin Cash (BCH) is a cryptocurrency that was created as a result of Bitcoin’s hard fork on August 1, 2017. The project is focused on struggling with the limitations existing in the original Bitcoin. Any user who had BTC at the time of the fork became the owner of an equivalent amount of BCH. The project’s main features that are stand out from the original Bitcoin: • Block size 8 MB, which allows processing more transactions faster. • Transactions protection from repeating and wiping out. • Security improvements. Today Bitcoin Cash is well known and fifth-largest cryptocurrency by market capitalization.
In 2019 the project has gone through the following milestones: • Bitcoin Cash protocol successfully implemented Schnorr signature functionality and Segwit recovery exemption. • Merchant adoption growth: 1,128 online merchants, 1,772 brick-and-mortar merchants. Moreover, various well-known retailers cooperated with Bitpay, adding more BCH acceptance to the overall landscape. • Privacy improvement: the full-featured version of Cashshuffle was introduced in March 2019. • The launch of a local BCH marketplace.
What to expect in the future?
The project’s main goal to become sound money that is usable by everyone in the world. The Bitcoin Cash team will concentrate on the further development of usability, extensibility, and scaling issues: • Adaptive Block Size. • Merklix-Metadata Tree. • Fractional Satoshis (fees low forever). • New Transaction Format (more capable, more compact) and so on.
The price for Bitcoin Cash price is forecasted to reach a maximum price of $259.186 per coin by the beginning of this August (+8.93%). By the end of December 2020, BCH expected maximum price will reach $228.149 (-4.11%), while the minimum price of BCH could be around $155.14 (-34.79%).

CryptoDiffer teamHello, everyone!We are glad to meet here:Max Freeman (@maxfreeman4), Project Lead at Epic CashYoga Dude (@Yogadude), PR&Marketing at Epic CashXenolink (@Xenolink), Advisor at Epic Cash Max Freeman Project Lead at Epic Cash Thanks Max, we are excited to be here! Yoga Dude PR&Marketing at Epic Cash Hello Everyone! Thank you for having us here! Xenolink Advisor at Epic Cash Thank you to the CryptoDiffer team and CryptoDiffer community for hosting us! CryptoDiffer teamLet`s start from the first introduction question:Q1: Can you introduce yourself to the community? What is your background and how did you join Epic Cash? Yoga Dude PR&Marketing at Epic Cash Hello! My background is Marketing and Business Development, I’ve been in crypto since 2011 started with Bitcoin, then Monero in 2014, Ethereum in 2015 and at some point Doge for fun and profit. I joined Epic Cash team in September 2019 handling PR and Marketing. I saw in Epic Cash what was missing in my previous cryptos — things that were missing in Bitcoin and Monero especially. Xenolink Advisor at Epic Cash Hello Cryptodiffer Community, I am not an original co-founder nor am I a developer for the Epic Cash project. I am however a community member that is involved in helping scale this project to higher levels. One of the many beauties of Epic Cash is that every single member in the community has the opportunity to be part of EPIC’s team, it can be from development all the way to content producing. Epic Cash is a community driven project. The true Core Team of Epic Cash is our community. I believe a community that is the Core Team is truly powerful. EPIC Cash has one of the freshest and strongest communities I have seen in quite a while. Which is one of the reasons why I became involved in this project. Epic displayed some of the most self community produced content I have seen in a project. I’m actually a doctor of medicine but in terms of my experience in crypto, I have been involved in the industry since 2012 beginning with mining Litecoin. Since then I have been doing deep dive analysis on different projects, investing, and building a network in crypto that I will utilize to help connect and scale Epic in every way I can. To give some credit to those people in my network that have been a part of helping give Epic exposure, I would like to give a special thanks to u/Tetsugan and u/Saurabhblr. Tetsugan has been doing a lot of work for the Japanese community to penetrate the Japanese market, and Japan has already developed a growing interest in Epic. Daku Sarabh the owner and creator of Crypto Daku Robinhooders, I would like to thank him and his community for giving us one of our first large AMA’s, which he has supported our project early and given us a free AMA. Many more to thank but can’t be disclosed. Also thank you to all the Epic Community leaders, developers, and Content producers! Max Freeman Project Lead at Epic Cash I’m Max Freeman, which stands for “Maximum Freedom for Mankind”. I started working on the ideas that would become Epic in 2018. I fell in love with Bitcoin in 2017 but realized that it needs privacy at the base layer, fungibility, better scalability in order to go to the next level. CryptoDiffer team Really interesting backgrounds I must admit, pleasure to see the team that clearly has one vision of the project by being completely decentralized:) Q2: Can you briefly describe what is Epic Cash in 3–5 sentences? What technology stands behind Epic Cash and why it’s better than the existing one? Max Freeman Project Lead at Epic Cash I’d like to highlight the differences between Epic and the two highest-valued privacy coin projects, Monero and Zcash. XMR has always-on privacy like Epic does, but at a cost: Its blockchain is over 20x more data intensive than Epic, which limits its possibilities for scalability. Epic’s blockchain is small and light enough to run a full node on cell phones, something that is in our product road map. ZEC by comparison can’t run on low end devices because of its zero knowledge based approach, and only 1% of transactions are fully private. Epic is simply newer, more advanced technology than prior networks thanks to Mimblewimble We will also add more algorithms to widen the range of hardware that can participate in mining. For example, cell phones and tablets based around ARM chips. Millions of people can mine Epic that can’t mine Bitcoin, and that will help grow the network rapidly. There are some great short videos on our YouTube channel https://www.youtube.com/channel/UCQBFfksJlM97rgrplLRwNUg/videos that explain why we believe we have created something truly special here. Our core architecture derives from Grin, so we are fortunate to benefit on an ongoing basis from their considerable development efforts. We are focused on making our currency truly usable and widely available, beyond a store of value and becoming a true medium of exchange. Yoga Dude PR&Marketing at Epic Cash Well we all have our views, but in a nutshell, we offer things that were missing in the previous cryptos. We have sound fiscal emission schedule matching Bitcoin, but we are vastly more private and faster. Our blockchain is lighter than Bitcoin or Monero and our tech is more scalable. Also, we are unique in that we are mineable with CPUs and GPUs as well as ASICs, giving the broadest population the ability to mine Epic Cash. Plus, you can’t forget FUNGIBILITY 🙂 we are big on that — since you can’t have true privacy without fungibility. Also, please understand, we have HUGE respect to all the cryptos that came before us, we learned a lot from them, and thanks to their mistakes we evolved. Xenolink Advisor at Epic Cash To add on, what also makes Epic Cash unique is the ability to decentralize the mining using a tri-algo model of Random X (CPU), Progpow (GPU), and Cuckoo (ASIC) for an ability to do hybrid mining. I believe this is an issue we can see today in Bitcoin having centralized mining and the average user has a costly barrier of entry. To follow up on this one in my opinion one of the things we adopted that we have seen success for , in example Bitcoin and Monero, is a strong community driven coin. I believe having a community driven coin will provide a more organic atmosphere especially when starting with No ICO, or Premine with a fair distribution model for everyone. CryptoDiffer team Q3: What are the major milestones Epic Cash has achieved so far? Maybe you can share with us some exciting plans for future weeks/months? Yoga Dude PR&Marketing at Epic Cash Since we went live in September of 2019, we attracted a very large community of users, miners, investors and contributors from across the world. Epic Cash is a very international project with white papers translated into over 30 languages. We are very much a community driven project; this is very evident from our content and the amount of translations in our white papers and in our social media content. We are constantly working on improving our usability, security and privacy, as well as getting our message and philosophy out into the world to achieve mass adoption. We have a lot of exciting plans for our project, the plan is to make Epic Cash into something that is More than Money. You can tell I am the Marketing guy since my message is less about the actual tech and more about the usability and use cases for Epic Cash, I think our Team and Community have a great mix of technical, practical, social and fiscal experiences. Since we opened our YouTube channels content for community submissions, we have seen our content translated into Spanish, French, German, Polish, Chinese, Japanese, Arabic, Russian, and other languages Max Freeman Project Lead at Epic Cash Our future development roadmap will be published soon and includes 4 tracks: Usability Mining Core Protocol Ecosystem Development Core Protocol Epic Server 2.9.0 — this release improves the difficulty adjustment and is aimed at making block emission closer to the target 60 seconds, particularly reducing the incidence of extremely short and long blocks — Status: In Development (Testing) Anticipated Release: June 2020 Epic Server 3.0.0 — this completes the rebase to Grin 3.0.0 and serves as the prerequisite to some important functional building blocks for the future of the ecosystem. Specifically, sending via Tor (which eliminates the need to open ports), proof of payment (useful for certain dex applications e.g. Bisq), and our native mobile app. Status: In Development (Testing) Anticipated Release: Fall 2020 Non-Interactive Transactions — this will enhance usability by enabling “fire and forget” send-to-address functionality that users are accustomed to from most cryptocurrencies. Status: Drawing Board Anticipated Release: n/a Scaling Options — when blocks start becoming full, how will we increase capacity? Two obvious options are increasing the block size, as well as a Lightning Network-style Layer 2 structure. Status: Drawing Board Anticipated Release: n/a Confidential Assets — Similar to Raven, Tari, and Beam, the ability to create independently tradable assets that ride on the Epic Blockchain. Status: Drawing Board Anticipated Release: n/a Usability GUI Wallet 2.0 — Restore from seed words and various usability enhancements — Status: Needs Assessment Anticipated Release: Fall 2020 Mobile App — Native mobile experience for iOS and Android. Status: In Development (Testing) Anticipated Release: Winter 2020 Telegram Integration — Anonymous payments over the Telegram network, bot functionality for groups. Status: Drawing Board Anticipated Release: n/a Mining RandomX on ARM — Our 4th PoW algorithm, this will enable tablets, cell phones, and low power devices such as Raspberry Pi to participate in mining. Status: Needs Assessment Anticipated Release: n/a The economics of mining Epic are extremely compelling for countries that have free or extremely cheap electricity, since anyone with an ordinary PC can mine. Individual people around the world can simply run the miner and earn meaningful money (imagine Venezuela for example), something that has not been possible since the very early days of Bitcoin. Ecosystem Development Atomic Swaps — Connecting Epic to other blockchains in a trustless way, starting with ETH so that Epic can trade on DeFi infrastructure such as Uniswap, Kyber, etc. Status: Drawing Board Anticipated Release: n/a Xenolink Advisor at Epic Cash From the Community aspect, we have been further developing our community international reach. We have been seeing an increase in interest from South America, China, Russia, Japan, Italy, and the Philippines. We are working on targeting more countries. We truly aim to be a decentralized project that is open to everyone worldwide. CryptoDiffer team Great, thank you for your answers, we now can move to community questions part! Cryptodiffer Community You have 3 mining algorithms, the question is: how do they not compete with each other? Is there any benefit of mining on the GPU and CPU if someone is mining on the ASIC? Max Freeman Project Lead at Epic Cash The block selection is deterministic, so that every 100 blocks, 60% are for RandomX (CPU), 38% for ProgPow (GPU), and 2% for Cuckoo (ASIC) — the policy is flexible so that we can have as many algorithms with any percentages we want. The goal is to make the most decentralized and resilient network possible, and with that in mind we are excited to work on enabling tablets and cell phones to mine, since that opens it up to millions of people that otherwise can’t take part. Cryptodiffer Community To Run a project smoothly, Funding is very important, From where does the Funding/revenue come from? Xenolink Advisor at Epic Cash Yes, early on this was realized and in order to scale a project funds are indeed needed. Epic Cash did not start with any funding and no ICO and was organically genesis mined with no pre-mine. Epic cash is also a nonprofit community driven project similar to Monero. There is no profit-driven entity in the picture. To overcome the revenue issue Epic Cash setup a development fund tax that decreases 1% every year until 2028 when Epic Cash reaches singularity with Bitcoin emissions. Currently it is at 7.77%. This will help support the scaling of the project. Cryptodiffer Community Hi! In your experience working also with MONERO can you please clarify which are those identified problems that EPIC CASH aims to develop and resolve? What’s the main advantage that EPIC CASH has over MONERO? Thank you! Yoga Dude PR&Marketing at Epic Cash First, I must admit that I am still a huge fan and HODLer of Monero. That said: ✅ our blockchain is MUCH lighter than Monero’s ✅ our transaction processing speed is much faster ✅ our address-less blockchain is more private ✅ Epic Cash can be mined with CPU (RandomX) GPU (ProgPow) and Cuckoo, whereas Monero migrated to RandomX and currently only mineable with CPU Cryptodiffer Community
the feature ‘Cut Through’ deletes old data, how is it decided which data will be deletes, and what are the consequences of it for the platform and therefore the users?
On your website I see links to download Epic wallet and mining software for Linux,Windows and MacOs, I am a user of android, is there a version for me, or does it have a release date?
Max Freeman Project Lead at Epic Cash
This is one of the most exciting features of Mimblewimble, which is its extraordinary ability to compress blockchain data. In Bitcoin, the entire history of a coin must be replayed every time it is spent, and comprehensive details are permanently stored in the blockchain. Epic discards spent transaction inputs and consolidates outputs, storing neither addresses or amounts, only a tiny kernel to allow sender and receiver to prove their transaction.
The Vitex mobile app is great for today, and we have a native mobile app for iOS and Android in the works as well.
Cryptodiffer Community $EPIC Have total Supply of 21,000,000 EPIC , is there any burning plan? Or Buyback program to maintain $EPIC price in the future? Who is Epic Biggest competitors? And what’s makes epic better than competitors? Xenolink Advisor at Epic Cash We respect the older generation coins like Bitcoin. But we have learned that the supply economics of Bitcoin is very sound. Until today we can witness how the Bitcoin is being adopted institutionally and by retail. We match the 21 million BTC supply economics because it is an inelastic fixed model which makes the long-term economics very sound. To have an elastic model of burning tokens or printing tokens will not have a solid economic future. Take for example the USD which is an inflating supply. In terms of competitors we look at everyone in crypto with respect and also learn from everyone. If we had to compare to other Mimblewimble tech coins, Grin is an inelastic forever inflating supply which in the long term is not sound economics. Beam however is an inelastic model but is formed as a corporation. The fair distribution is not there because of the permanent revenue model setup for them. Epic Cash a non-profit development tax fund model for scaling purposes that will disappear by 2028’s singularity. Cryptodiffer Community What your plans in place for global expansion, are you focusing on only market at this time? Or focus on building and developing or getting customers and users, or partnerships? Yoga Dude PR&Marketing at Epic Cash Since we are a community project, we have many developers, in addition to the core team. Our plans for Global expansion are simple — we have advocates in different regions addressing their audiences in their native languages. We are growing organically, by explaining our ideology and usability. The idea is to grow beyond needing a fiat bridge for crypto use, but to rather replace fiat with our borderless, private and fungible crypto so people can use it to get goods and services without using banks. We are not limiting ourselves to one particular demographic — Epic Cash is a valid solution for the gamers, investors, techie and non techie people, and the unbanked. Cryptodiffer Community EPIC confidential coin! Did you have any problems with the regulators? And there will be no problems with listing on centralized exchanges? Xenolink Advisor at Epic Cash In terms of structure, we are carefully set up to minimize these concerns. Without a company or investors in the picture, and having raised no funds, there is little scope to attack in terms of securities laws. Bitcoin and Ethereum are widely acknowledged as acceptable, and we follow in their well-established footprints in that respect. Centralized exchanges already trade other privacy coins, so we don’t see this as much of an issue either. In general, decentralized p2p exchange options are more interesting than today’s centralized platforms. They are more censorship resistant, secure, and privacy-protecting. As the technology gets better, they should continue to gain market share and that’s why we’re proud to be partnered with Vitex, whose exchange and mobile app work very well. Cryptodiffer Community What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment? Max Freeman Project Lead at Epic Cash Because our blockchain is so light (only 1.16gb currently, and grows very slowly) it is naturally well suited to become a decentralized mobile money standard because people can run a full node on their phone, guaranteeing the security of their funds. Scalability in Bitcoin requires complicated and compromised workarounds such as Lightning Network and light clients, and these problems are solved in Epic. With our forthcoming Mobile Mining app, hundreds of millions of cell phones and tablets will be able to easily join the network. People can quickly and cheaply send money to one another, fulfilling the long-envisioned promise of P2P electronic cash. As an investor, it’s important to ask a few key questions. Bitcoin Standard tokenomics of disinflation and a fixed supply are well proven over a decade now. We follow this model exactly, with a permanently synchronized supply from 2028, and 4 emission halvings from now until then, with our first one in about two weeks. Beyond that, we can apply some simple logical tests. What is more valuable, money that can only be used in some cases (censorable Bitcoin based on a lack of fungibility) or money that can be used universally? (fungible Epic based on always-on privacy by default). Epic is also poised to be a more decentralized and therefore resilient network because of wider participation in mining. Epic is designed to be Bitcoin++ Privacy, Fungibility, Scalability Cryptodiffer Community Q1. What are advantages for choosing three mining algorithms RandomX+, ProgPow and CuckAToo31+ ? Q2. Beam and Grin use MimbleWimble protocol, so what are difference for Epic? All of you will be friends for partners or competitors? Max Freeman Project Lead at Epic Cash RandomX and ProgPow are designed to use the entirety of a CPU / GPU’s unique processing capabilities in a way that other types of hardware don’t work as well. You can run RandomX on a GPU but it doesn’t work nearly as well as a much cheaper CPU, for example. Cuckoo is a “memory hard” algorithm that widens the range of companies that can produce the hardware. Grin and Beam are great projects and we’ve learned a lot from them. We inherited our first codebase from Grin’s excellent Rust design, which is a better language for community participation than C++ that Beam currently uses. Functionally, Mimblewimble is similar across the 3 coins, with standard Confidential Transactions, CoinJoin, Dandelion++, Schnorr Signatures and other advanced features. Grin is primarily ASIC-targeted, Beam is GPU-targeted, and Epic is multi-hardware. The biggest differences though are in tokenomics and project structure. Grin has permanent inflation of 60 coins per block with no halvings, which means steady erosion of value over time due to new supply pressure. It also lacks a steady funding model, making future development in jeopardy, particularly as the per coin price falls. Beam has a for-profit model with heavy early inflation and a high developer tax. Epic builds on the strengths of these earlier mimblewimble projects and addresses the parts that could be improved. Cryptodiffer Community Some privacy coin has scalability issues! How Epic cash will solve scalability issues? Why you choose randomX consensus algorithem? Xenolink Advisor at Epic Cash Fungibility means that you can’t distinguish one unit of currency from another, in example Gold. Fungibility has recently become a hot issue as people have been noticing Bitcoins being locked up by exchanges which may of had a nefarious history which are called Tainted Coins. In example coins that have been involved in a hack, darknet market transactions, or even processing coin through a mixer. Today we can already see freshly mined Bitcoins being sold at a premium price to avoid the fungibility problem Bitcoin carries today. Bitcoin can be tracked by chainalysis and is not a fungible cryptocurrency. One of the features that Epic has is privacy with added fungibility, because of Mimblewimble technology, Epic has no addresses recorded and therefore nothing can be tracked by chainalysis. Below I provide a link of an example of what the lack of fungibility is resulting in today with Bitcoin. One of the reasons why we chose the Random X algo. is because of the easy barrier of entry and also to further decentralize the mining. Random X algo can be mined on old computers or laptops. We also have 2 other algos Progpow (GPU), and Cuckoo (ASIC) to create a wider decentralization of mining methods for Epic. Cryptodiffer Community I’m a newbie in crypto and blockchain so how will Epic Cash team target and educate people who don’t know about blockchain and crypto? What is the uniqueness of Epic Cash that cannot be found in other project that´s been released so far ? Yoga Dude Pr&Marketing at Epic Cash Actually, while we have our white paper translated into over 30 languages, we are more focused on explaining our uses and advantages rather than cold specs. Our tech is solid, but we not get hung up on pure tech talk which most casual users do not need to or care to understand. As long as our fundamentals and tech are secure and user friendly our primary goal is to educate about use cases and market potential. The uniqueness of Epic Cash is its amalgamation of “whats good” in other cryptos. We use Mimblewimble for privacy and anonymity. Our blockchain is much lighter than our competitors. We are the only Mimblewimble crypto to use a unique cocktail of mining algorithms allowing to be mined by casual miners with gaming rigs and laptops, while remaining friendly to GPU and CPU farmers. The “uniqueness” is learning from the mistakes of those who came before us, we evolved and learned, which is why our privacy is better, we are faster, we are fungible, we offer diverse mining and so on. We are the best blend — thats powerful and unique Cryptodiffer Community Can you share EPIC’s vision for decentralized finance (DEFI)? What features do EPIC have to support DEFI? Yoga Dude PR&Marketing at Epic Cash We view Epic as ideally suited to be the decentralized digital reserve asset of the new Private Internet of Money that’s emerging. At a technology level, atomic swaps can be created to build liquidity bridges so that wrapped Epic tokens (like WBTC, WETH) can trade on other networks as ERC20, BEP2, NEP5, VIP180, Algorand and so on. There is more Bitcoin value locked on Ethereum than in Lightning Network, so we will similarly integrate Epic so that it can trade on networks such as Uniswap, Kyber, and so on. Longer term, if there is market demand for it, thanks to Scriptless Script functionality our blockchain has, we can build “Confidential Assets” (which Raven, Tari, and Beam are all also working on) that enable people to create tokenized assets in a private way. Cryptodiffer Community If you could choose one celebrity to promote Epic-cash, who that would be? Max Freeman Project Lead at Epic Cash I am a firm believer that the strength of the project lies in allowing community members to become their own celebrities, if their content is good enough the community will propel them to celebrity status. Organic celebrities with small but loyal following are vastly more beneficial than big name professional shills with inflated but non caring audiences. I remember the early days of Apple when an enthusiastic dude named Guy Kawasaki became Apple Evangelist, he was literally going around stores that sold Apple and visited user groups and Evangelized his belief in Apple. This guy became a Legend and helped Apple become what it is today. Epic Cash will have its OWN Celebrities Cryptodiffer Community How does $EPIC solve scalability of transactions? Current blockchains face issues with scalability a lot, how does $EPIC creates a solution to it? Xenolink Advisor at Epic Cash Epic Cash is utilizing Mimblewimble technology. Besides the privacy & fungibility aspect of the tech. There is the scalability features of it. It is implemented into Epic by transaction cut-through. Which means it allows nodes to remove all intermediate transactions, thus significantly reducing the blockchain size without affecting its validation. Mimblewimble also does not use addresses like a BTC address, and amount of transactions are also not recorded. One problem Monero and Bitcoin are facing now is scalability. It is evident today that data is getting more expensive and that will be a problem in the long run for those coins. Epic is 90% lighter and more scalable compared to Monero and Bitcoin. Cryptodiffer Community what are the ways that Epic Cash generates profits/revenue to maintain your project and what is its revenue model ? How can it make benefit win-win to both invester and your project ? Max Freeman Project Lead at Epic Cash There is a block subsidy of 7.77% that declines 1.11% per year until 0, where it stays after that. As a nonprofit community effort, this extremely modest amount goes much further than in other projects, which often take 20, 30, even 50+ % of the coin supply. We believe that this ongoing funding model best aligns the long term incentives for all participants and balances the compromises between the ends of the centralized/decentralized spectrum of choices that any project must make. Cryptodiffer Community Q1 : What are your major goals to archive in the next 3–4 years? Q2 : What are your plans to expand and gain more adoption? Yoga Dude Pr&Marketing at Epic Cash Max already talked about our technical plans and goals in his roadmap. Allow me to talk more about the non technical 😁 We are aiming for broader reach in the non technical more mainstream community — this is a big challenge but we believe it is doable. By offering simpler ways to mine Epic Cash (with smart phones for example), and by doing more education we will achieve the holy grail of crypto — moving past the fiat bridges and getting Epic Cash to be accepted as means of payment for goods and services. We will accomplish this by working with regional advocacy groups, community interaction, off-line promotional activities and diverse social media targeting. Cryptodiffer Community It seems to me that EpicCash will have its first Halving, right? Why a halving so soon? Is a mobile version feasible? Max Freeman Project Lead at Epic Cash Our supply emission catches up to that of Bitcoin’s first 19 years after 8 years in Epic, so that requires more frequent halvings. Today’s block emission is 16, next up are 8, 4, 2, and then finally 0.15625. After that, the supply of Epic and that of BTC stay synchronized until maxing out at 21m coins in 2140. Today we have a mobile wallet through the Vitex app, a native mobile wallet coming, and are working on mobile mining. Cryptodiffer Community What markets will you add after that? Yoga Dude PR&Marketing at Epic Cash Well, we are aiming to have ALL markets Epic Cash in its final iteration will be usable by everyone everywhere regardless of their technical expertise. We are not limiting ourselves to the technocrats, one of our main goals is to help the billions of unbanked. We want everyone to be able to mine, buy, and most of all USE Epic Cash — gamers, farmers, soccer moms, students, retirees, everyone really — even bankers (well once we defeat the banking industry) We will continue building on the multilingual diversity of our global community adding support and advocacy groups in more countries in more languages. Epic Cash is More than Money and its for Everyone. Cryptodiffer Community Almost, all cryptocurrencies are decentralized & no-one knows who owns that cryptocurrencies ! then also, why Privacy is needed? hats the advantages of Private coins? Max Freeman Project Lead at Epic Cash With a public transparent blockchain such as Bitcoin, you are permanently posting a detailed history of your money movements open for anyone to see (not just legitimate authorities, either!) — It would be considered crazy to post your credit card or bank statements to Twitter, but that’s what is happening every time you send a transaction that is not private. This excellent video from community contributor Spencer Lambert https://www.youtube.com/watch?v=0blbfmvCq\_4 explains better than I can. Privacy is not just for criminals, it’s for everyone. Do you want your landlord to increase the rent when he sees that you get a raise? Your insurance company to raise your healthcare costs because they see you buying too much ice cream? If you’re a business, do you want your employees to see how much money their coworkers make? Do you want your competitors to trace your supplier and customer relationships? Of course not. By privacy being default for everyone, cryptocurrency can be used in a much wider range of situations without unacceptable compromises. Cryptodiffer Community What are the main utility and real-life usage of the #EPIC As an investor, why should we invest in the #EPIC project as a long-term investment? Xenolink Advisor at Epic Cash Epic Cash can be used as a Private and Fungible store of value, medium of exchange, and unit of account. As Epic Cash grows and becomes adopted it can be compared to how Bitcoin and Monero is used and adopted as well. As Epic is adopted by the masses, it can be accepted as a medium of exchange for store owners and as fungible payments without the worry of having money that is tainted. Epic Cash as a store of value may be a good long term aspect of investment to consider. Epic Cash carries an inelastic fixed supply economic model of 21 million coins. There will be 5 halvings which this month of June will be our first halving of epic. From a block reward of 16 Epic reduced to 8. If we look at BTC’s price action and history of their halvings it has been proven and show that there has been an increase in value due to the scarcity and from halvings a reduction of # of BTC’s mined per block. An inelastic supply model like Bitcoin provides proof of the circulating supply compared to the total supply by the history of it’s Price action which is evident in long term charts since the birth of Bitcoin. EPIC Plans to have 5 halvings before the year 2028 to match the emissions of Bitcoin which we call the singularity event. Below is a chart displaying our halvings model approaching singularity. Once bitcoin and cryptocurrency becomes adopted mainstream, the fungibility problem will be more noticed by the general public. Privacy coins and the features of fungibility/scalability will most likely be sought over. Right now a majority of people believe that all cryptocurrency is fungible. However, that is not true. We can already see Chainalysis confirming that they can trace and track and even for other well-known privacy coins today such as Z-Cash. Cryptodiffer Community
You aim to reach support from a global community, what are your plans to get spanish speakers involved into Epic Cash? And emerging markets like the african
How am I secure I won’t be affected by receiving tainted money?
Max Freeman Project Lead at Epic Cash Native speakers from our community are working to raise awareness in key markets such as mining in Argentina and Venezuela for Spanish (Roberto Navarro called Epic “the holy grail of cryptocurrency” and Ethiopia and certain North African countries that have the lowest electricity costs in the world. Remittances between USA and Latin American countries are expensive and slow, so Epic is also perfect for people to send money back home as well. Cryptodiffer Community Do EPICs in 2020 focus more on research and coding, or on sales and implementation? Yoga Dude PR&Marketing at Epic Cash We will definitely continue to work on research and coding, with emphasis on improved accessibility (especially via smartphones) usability, security and privacy. In terms of financial infrastructure will continuing to add exchanges both KYC and non KYC. Big part of our plans is in ongoing Marketing and PR outreach. The idea is to make Epic Cash a viral sensation of sorts. If we can get Epic Cash adopters to spread the word and tell their family, coworkers and friends about Epic Cash — there will be no stopping us and to help that happen we have a growing army of content creators, and supporters. Everyone with skin in the game gets the benefit of advancing the cause. Folks also, this isn’t an answer to the question but an example of a real-world Epic Cash content — https://www.youtube.com/watch?v=XtAVEqKGgqY a challenge from one of our content creators to beat his 21 pull ups and get 100 epics! This has not been claimed yet — people need to step up 🙂 and to help that I will match another 100 Epic Cash to the first person to beat this Cryptodiffer Community I was watching some videos explaining how to send and receive transactions in EpicCash, which consists of ports and sending links, my question is why this is so, which, for now, looks complex? Let’s talk about the economic model, can EpicCash comply with the concept of value reserve? Max Freeman Project Lead at Epic Cash In V3, which is coming later this summer, Epic can be sent over Tor, which eliminates this issue of port opening, even though using tools like ngrok.io, it’s not necessarily as painful as directly configuring the router ports. Early Lightning Network had this issue as well and it’s something we have a plan to address via research into non-interactive transactions. “Fire and Forget” payments to an address, as people are used to in Bitcoin, is coming to Epic and we’re excited to develop functionality that other advanced mimblewimble coins don’t yet have. We are committed to constant improvement in usability and utility, to make our money system the ease of use leader. We are involved in the project (anyone can join the Freeman Family) because we believe that simply by choosing to use a form of money that better aligns with our ideals, that we can make a positive change in the world. Some of my thoughts about how I got involved are here: https://medium.com/epic-cash/the-freeman-family-e3b9c3b3f166 Max Freeman Project Lead at Epic Cash Huge thanks to our friends Maks and Vladyslav, we welcome everyone to come say hi at one of our friendly communities. It is extremely early in this journey, our market cap is only 0.5m right now, whereas the 3 other mimblewimble coins are at $20m, $30m and $100m respectively. Epic is a historic opportunity to follow in the footsteps of legends such as Bitcoin and Monero, and we hope to become the first Top 5 privacy coin project. Xenolink Advisor at Epic Cash Would like to Thank the Cryptodiffer Team and the Cryptodiffer community for hosting us and also engaging with us to learn more about Epic. If anyone else has more questions and wants to know more about EPIC , can find us at our telegram channel at https://t.me/EpicCash . Yoga Dude Pr&Marketing at Epic Cash Thank you, CryptoDiffer Team, and this wonderful Community!!! Cryptodiffer TEAM Thank you everyone for taking your time and asking great questions Thank you for your time, it was an insightful session Spread the love
I converted my BTC to XRP about a year ago. I just converted my XRP to XMR a couple of weeks ago. Full disclosure. I am a speculator, not planning on using XMR as a currency, although not opposed to it if it were to happen. Pretty skeptical that it will anytime soon. Anyhow. I am seeing correlations in BTC and XMR more than I saw between BTC and XRP. Not sure I like that as I feel BTC is in full bubble territory. Thoughts?

So here in this article, I will focus on the last scaling solution i.e SegWit. What is SegWit? SegWit stands for Segregating Witness i.e separating the signatures from the transactions. In this process, certain parts of a transaction are removed, which will free up space so that more transactions can be added to the chain. The idea behind using this method is to overcome the block size limit of blockchain transactions. In simple terms, SegWit changed the way data are stored, therefore helping the Bitcoin network to run faster and more smoothly.
It was suggested as a soft fork change in the transaction format of Bitcoin in the Bitcoin Improvement Proposal number BIP141.
Problem Statement In the Bitcoin platform, Blocks are getting generated every 10 minutes and are constrained to a maximum size of 1 megabyte (MB). As the number of transactions is increasing, more blocks need to be added to the chain. But due to the block size constraint, only a certain number of transactions can be added to a block. The weight of the transactions can cause delays in processing and verifying transactions. Sometimes, it takes hours to confirm a transaction as valid. This can slow down further when the network is busy. The Solution To overcome the block size limit issue and to enhance the transaction speed, the transaction is divided into two segments. Removing the unlocking signature (witness) from the original portion and appending it as a separate structure at the end. The original portion will still have the sender and receiver data, and the new "witness" structure would contain scripts and signatures. The original data segment would be counted normally, but the new "witness" segment becomes one-fourth of its original size.
Digital signature accounts for 65% of the space in a given transaction.
SegWit is backward compatible, which means nodes that are updated with the SegWit Bitcoin protocol can still work with nodes that haven’t been updated. SegWit measures blocks by block weight. The formula used to calculate block weight: (tx size with witness data stripped) * 3 + (tx size) Since segregated witness creates a sidechain where witness data is stored, it prevents transaction IDs from being altered by dishonest users. It also addresses signature malleability, by serializing signatures separately from the rest of the transaction data, so that the transaction ID is no longer malleable. History Pieter Wuille, a bitcoin developer, first proposed the concept of SegWit. On 24 July 2017 as a part of the software upgrade process i.e Bitcoin Improvement Proposal (BIP) 91, the concept of Segregated Witness is activated at block 477,120. Within one week of implementation, the bitcoin price seen a spike of 50%. The transaction usage rate using SegWit further increased from 7% to 10% in the first week of October. As of February 2018, SegWit transactions exceed 30%. However, a group of China-based bitcoin miners were unhappy with the implementation and later forked to created Bitcoin Cash. Lightning Network - Layer 2 solution Lightning Network operates on top of bitcoin and is referred to as a “Layer 2” component. It is an off-chain micropayment system that is designed to enhance the transaction speed in the blockchain network. SegWit acts as a base component for the Lightning Network. By implementing SegWit, the transaction malleability issue can be prevented which will allow this secure payment system to process millions of transactions per second in the Bitcoin network. Advantages of SegWit: · Prevents transaction malleability problem. · Prevents signature malleability problem. · Helps in scaling the bitcoin network. · Increases block size. · Reduced transaction fees. · Acts as a base for the lightning protocol. Conclusion There is no doubt that Bitcoin technology is very revolutionary but like any other technology, it has certain drawbacks as well as challenges. Scaling is one of them which has restricted in large scale applications adopted. It is capable of processing only 7-10 transactions per second on the base layer. Many developers, researchers from the Bitcoin community are working hard to overcome the problem. SegWit along with the Lightning Network together aiming to allow Bitcoin to process millions (or more) transactions per second. But the real scenario will depend on the success of future projects.

https://preview.redd.it/7nfccptuway41.png?width=1200&format=png&auto=webp&s=0103130266549ba8ae21e63d837b67528e39f59c In my previous article, I have covered one of the most famous consensus mechanism i.e Proof of Work. But like any technology, that protocol also has a certain drawback, and to overcome these issues another protocol has been developed i.e Proof Of Stake. Proof Of Stake, as the name implies depends upon the stake of a validator. Like Miners in PoW, PoS consists of a group of validators. These validators use a pseudo-random algorithm to select a node that will act as a validator for the next block. The validator was decided based on a combination of different factors which includes the staking age and the node’s wealth. This means that the more coin one has, the more mining power he or she will have. Thus unlike PoW which is quite a power extensive because it depends upon solving a complex computational puzzle to decide the next block, the validation and generation of next block in PoS solely depend on the owner's stake. In Proof of Stake systems, the blocks that were mined are termed as ‘forged’. This algorithm was introduced in 2011 with the idea to solve the problems with Proof of Work. Though both these algorithm is used to achieve consensus in the blockchain network, the underlying process to reach the final goal is different. Some of the crypto coins like Nxt (NXT), Blackcoin, ShadowCoin, and Peercoin (PPC) uses the PoS method. Ethereum (ETH) is also planning to switch to a PoS system. How do PoS works? The blockchain network consists of a series of a node which acts as a miner (Forge in this case). Any network user who wants to participate in the forging activity needs to stake a certain amount of coin into the network. One can do this by sending a special transaction that will lock up their base cryptocurrency(in Ethereum's case, ether). The stake size determines the chances of a node to be selected as the next validator who will forge the next block. The bigger the stake, the higher the chances. The newly created node which got selected to forge the next block checks the validity of the transactions in the block. If the transactions are valid, it then signs the block and adds it to the blockchain network. The node receives the transaction fees that are associated with the transactions in the block as a reward. In the case when the node doesn’t want to serve as a forger, it can withdraw its stake along with the rewards earned. The network verifies and releases the node once it successfully checks that the node has not been involved in any malicious activity. Advantages of using PoS:- o Enhanced security. o Energy-efficient. o Reduced risk of centralization. Forge selection method:- Two unique methods are being used in case there is a requirement of not selecting the node with the maximum stake. These are:- o Randomized Block Selection In this method, a node gets selected as the validators which are having a combination of the lowest hash value and the highest stake. The account which will receive the right to forge a block can be easily predicted by each node because the stakes are public o Coin Age Selection method In this method, a node gets selected as the validators who have kept their stake for a longer period. The Coin age is calculated by multiplying the number of days the coins have been reserved as stake by the number of coins that are available as stake. Coin age=no.of days coined staked *total no of coins staked The coin age of a node has been reset to zero once it forged a block. To forge another block, the node has to wait for a certain period. Hence this method prevents the large stake nodes from dominating the blockchain network. Different types of PoS Proof Of Stake can be categorized into two parts:- o Chain-based proof of stake This algorithm randomly selects a validator during the time slot (e.g. every period of 10 seconds might be a time slot) available to create a block, and then assign it an authority to create a block with the constraint that the block must point to some previous block. Generally, it points to the last block of the longest chain. Hence over time, the blocks converge into one growing chain. Blockchain projects that implemented this model are Nxt, Peercoin, Ardor. o BFT-style proof of stake This model offers ‘consistency’. Here the randomly chosen validators decide whether a particular block can be included in the chain or not at the end of each round. This type could be favored for a more “permission” approach. In this case, the consensus on a block does not depend on the length or size of the chain. Blockchain projects that implemented this model are Neo, Tendermint, Polkadot, Hyperledge Fabric. How it reduces the risk of a Network attack? Since this model works on the concept of the stake owned by the validator, thus to effectively control the network and approve fraudulent transactions, a node has to own a majority stake in the network (also known as the 51% attack) which is quite impractical because if a hacker tries to purchase 51% of the total number of coins, the market reacts by the fast price appreciation. Also, wherever the network detects any fraudulent transaction, not only the forger node loses a part of its stake but is also restricted from participating in future activities. Till the time the cost of staking is higher than the reward, the validator is at a loss in case of attempting fraud. With the “Casper” upgrade underway for Ethereum, Proof-of-Stake (POS) model is gaining more popularity among other Blockchain consensus designs. With this upgrade, the protocols will set certain criteria that will identify a bad validator. The bad validator would lose their deposit if proven, thus making this model more secure.

Introducing the halvinggame.com: Put your money where your mouth is.
Introducing The Halving Game, a fun platform about anticipating the Bitcoin price. Can you predict the BTC/USDT price on Binance at the time of halving on May 12? Then make your bet and win your share of the pot! It’s 100% anonymous, no email address required. How does it work? Everyone makes one or more bets with their own price prediction. At the time of halving (when block 630,000 hits), those bets within a +/- 2.5% range (target zone) around the Binance price will be paid out their share of the pot. For example, if the price at the time of the halving is 10,000 USDT, you would have your bet(s) placed between 9,750 USDT and 10,250 USDT (-2.5% to +2.5%). The minimum bet size is 1 bit, or 100 satoshi. Weight factor The weight factor spices things up even more and rewards older bets over younger ones, i.e the earlier you bet the greater your weight factor will be. For example, if you bet 14 days before the halving, the weight factor of your bet is 14.0. If you’re in the target zone, your share of the pot will be your bet multiplied by 14, so be quick because a bet only 7 days before the halving will have a weight factor of just 7.0. On the last day of the game, each bet only counts 1x. TL;DR: Bet as early as possible to get the maximum output. Payout calculation After the halving, the pot is distributed to those players whose bets are within the price range. The formula for the payout is: sum of my weighted bets in target zone / sum of all weighted bets in target zone Service fee We’re charging a modest fee of 2% to operate the service and provide support. The service fee is deducted at the time of payout. Good Luck! The game starts today, 14 days before the halving and bets will be allowed until block 629995, 5 blocks until the halving. Check it out at https://halvinggame.com. Follow us on twitter at https://twitter.com/HalvingGame And now we wish you all good luck! Also, any feedback is most welcome!
The Bitcoin block size limit is a parameter in the Bitcoin protocol that limits the size of Bitcoin blocks, and, therefore, the number of transactions that can be confirmed on the network approximately every 10 minutes. Although Bitcoin launched without this parameter, Satoshi Nakamoto added a 1 megabyte block size limit back when he was still the lead developer of the project. This translated ... The truth is: there is no maximum Ethereum block size. While Bitcoin has a fixed block size of 1 mb, Ethereum’s block size varies. What determines Ethereum block size? Instead of a fixed limit, Ethereum block size is bound by how many units of gas can be spent per block. This limit is known as the block gas limit (sometimes confused with transaction gas limit). At the time of writing this ... But these factors aren't a simple function; the procedure I'd prefer would be something like this: if there is a standing backlog, we-the-community of users look to indicators to gauge if the network is losing decentralization and then double the hard limit with proper controls to allow smooth adjustment without fees going to zero (see the past proposals for automatic block size controls that ... The issue of raising the 1MB block size limit came to the forefront as Bitcoin transactions fees were hitting record highs at the end of last year. SegWit, however, was implemented via soft-fork and was thus an optional upgrade. This is why it’s taken months for exchanges, businesses, and users to see network-wide benefits such as lower fees and bigger blocks.
