Technology Weekly|ETH2.0 Genesis block is expected to start in November



This week's Technology Weekly contains technical news about the two networks of Ethereum and Filecoin. Ethereum 2.0 project leader: Ethereum 2.0 deposit contract will be launched within two weeks On October 23, Danny Ryan, director of the Ethereum 2.0 project, said that the Ethereum 2.0 deposit contract will be launched within two weeks. He said that the first version of the Ethereum 2.0 specification must be launched first, and then the deposit contract will be launched. There are two reasons why they haven't released the final 2.0 specification yet. The main reason is the BLS cryptographic library created by Supranational. Danny Ryan said that Boneh–Lynn–Shacham (BLS) signatures are essential for creating keys, signing messages, and are important in the early stages. He said that the BLS cryptographic library is currently being audited, and some preliminary results have been obtained, and there are still about two weeks to audit. Danny Ryan said: "Although the deposit contract has been written, tested and formally verified, we are working hard to make the standardization of the BLS stable before the release..." Ryan further said that there are other things, such as customer hardening, Tethering failures, optimizing resource consumption, ongoing customer audits, smoothing the launchpad, all these things are going on in parallel, but the biggest blocker is the audit of the brand new BLS cryptographic library. (Trust Nodes) V God: The review of MESS is disappointing and does not provide much security. ETC is implementing a 51% attack solution MESS. V God, the founder of Ethereum, tweeted that this is what I hate the most One point: "Anchoring" one ledger to another doesn't actually provide much security. All it does is ask the attacker to start building the attack chain at the same time as the legitimate chain, and anchor the attack chain without publishing blocks. He said the review of MESS was disappointing, especially the critique of subjectivity. This is because anything that is not subjective is either centralized (as in the checkpointing proposal) or nonfunctional (as in anchoring). If timestamps are an issue (I haven't thought much about this, my original ESS proposal didn't use timestamps)...why not use client receive time instead of something like timestamps, is this discussed? News | Sichuan Province will strengthen technical research and application scenarios such as blockchain: According to People's Daily Online, in 2020, Sichuan Province will strengthen technological research and application scenarios such as artificial intelligence and blockchain, and hold a blockchain innovation expo. [2020/1/19] ETH 2.0 project leader: the Genesis block is expected to start in November This week, Danny Ryan, the leader of the Ethereum 2.0 project, said that the Ethereum 2.0 deposit contract is imminent. He said, "What can be guaranteed is that everyone is working hard." Danny Ryan suggested that nodes continue to run the Medalla testnet. At the same time, he said, a blocker is in the process of deciding "MIN_GENESIS_TIME", which is the date when the genesis block cannot be rolled out. If the minimum deposit requirement of 500,000 ETH is met, then the genesis block can start once the time of the genesis block is met, it is not clear if there are any other significant deterring factors. But either way, in less than two weeks, the Genesis block is expected to launch in November. (Trust Nodes) The Ethereum community discusses a new scheme to reduce the number of witnesses on ETH 1.x. V God released a community discussion on whether to use the "Kate Commitment" scheme. The content-zce shows that Vitalik proposed to use the "Kate commitments" scheme to reduce the number of witnesses when submitting the Ethereum contract code on ETH 1.x. Specifically, in stateless Ethereum, miners need to add proofs of all executed code for witnesses. The size of the proof is linear to the size of the contract code and must include the entire code segment. Code merging is proposed for this existing solution, and the proof size increases logarithmically with the contract code size. The "Kate Commitment" scheme goes a step further, and its commitment will provide proofs of invariant size. At the same time, the number of witnesses is the key to determine whether stateless Ethereum can be used. So far, the "Kate Commitment" scheme is very attractive. But this scheme also has a big disadvantage, which requires a trusted setup. Voice | Vice Chairman of Heilongjiang CPPCC: Use blockchain and other new generation information technology to boost the modernization of Longjiang governance: On January 15th, Pang Da, vice chairman of Heilongjiang CPPCC, said that Internet, big data, cloud computing, artificial intelligence, Data-based new-generation information technologies such as 5G and blockchain are playing an increasingly important role in the modernization of national governance. To deal with the "double-edged sword" attribute of blockchain technology, it is necessary to improve the ability and level of applying a new generation of information technology. Pangda put forward three suggestions for this, including eliminating data barriers and promoting digital government affairs; eliminating capacity panic, focusing on popularization and application, and actively supporting enterprises that use new generation information technologies such as blockchain; eliminating collaboration barriers, integrating superior resources, and promoting regional Blockchain technology is deeply integrated with artificial intelligence, big data, Internet of Things and other technologies to promote the application of a new generation of information technology in multiple fields and scenarios in the construction of Heilongjiang Province. (Heilongjiang Daily) [2020/1/15] ConsenSys and Protocol Labs cooperated to integrate Filecoin into the Ethereum development tool Golden Finance reported that the blockchain company ConsenSys has officially started cooperation with the open source software laboratory Protocol Labs to integrate Filecoin data The storage marketplace is integrated with ConsenSys' Ethereum offering. According to the announcement, Filecoin miners, developers, and network users will be able to access ConsenSys' development tools, such as Infura and MetaMask, to integrate with Ethereum's decentralized financial ecosystem. V God Releases Gitcoin Funding Report The Ethereum project has raised a total of more than 720,000 US dollars. The report reveals that Ethereum projects saw a significant increase in funding raised in Gitcoin Funding Round 7, raising $274,830 in donations and $450,000 in matching funds allocated to 857 projects. Ethereum EIP-1559 progress update: DoS risk is still the biggest obstacle to landing Voice | Dongtu Technology: The company's chips do not involve blockchain technology: Dongtu Technology stated on the interactive platform that the company's chips do not involve blockchain technology. At present, the company mainly starts to cooperate with the layout of 5G business through smart factories. At the same time, the company participates in the research projects of 5G topics of Beijing Municipal Science and Technology Commission and the Ministry of Industry and Information Technology. [2019/11/25] Tim Beiko, senior product manager of ConsenSys, posted an update on the progress of the Ethereum EIP-1559 proposal. According to the article, the biggest obstacle to landing EIP-1559 is still the DoS risk issue, but there are already some solutions. In addition, he said: 1. The Besu and Nethermind clients are synchronizing to the 1559 test network, and the Geth consensus problem is being debugged. A lot of research and development work is in progress; the next step is to make more progress on the GethBesu Nethermind test network, and hope to start a PoW network to test Support the mining of EIP-1559; 2. The main network readiness checklist is online; 3. The Ethereum Cat Herders in the community have released a community survey report on the EIP-1559 proposal; next, the Ethereum Cat Herders will Make more contacts with wallets and exchanges to gather feedback on 1559. 4. The next step is to look forward to a series of EIPs for adding support for 1559 in the JSON-RPC specification. ConsenSys released a blog to introduce Teku, an Ethereum 2.0 client for institutional stakingConsenSys released a blog to introduce Teku, an Ethereum 2.0 client, saying that it is a complete Ethereum 2.0 client that meets the staking needs of institutional users, and is the only one fully supported by ConsenSys client, which means not receiving any financial support from the Ethereum Foundation. Another open source project of Teku and ConsenSys, Web3Signer, can provide remote key signing and slashing protection services for institutional staking to maximize security. Many of ConsenSys' Eth2 products are built on Teku, and Infura has been running Teku in a production-level environment to support its Eth2BeaconChainAPI service; the upcoming Codefi Staking will mainly rely on Teku as its white label platform to manage Eth2 hosting infrastructure. Sound | CLP Xingfa: The core technology points include the application of blockchain technology: CLP Xingfa [002298] was asked "whether the company has blockchain technology" and said, "The essence of blockchain technology is decentralization And it resides in the method of data storage, transmission and certification in a distributed structure. Its closely related technologies mainly focus on distributed storage and encryption algorithms based on cryptography. It is a computer technology for blockchain applications. The company's technology accumulation is Including the direction of distributed computing and distributed storage, it is the core technical point of blockchain applications.” (Interaction Easy) [2019/11/1] Filecoin has released lotus 1.1.1 version Filecoin developer Jennifer said that the lotus has been released Version 1.1.1 to improve wincount and block propagation. Although this is not a consensus-breaking upgrade, it is strongly recommended that all miners and node operators update to this version as soon as possible, especially any miners who have recently changed their worker keys. If it is not updated, the synchronization of several blocks may be turned off at intervals in a short period of time. This also does not reset the network, so there is no need to delete the Llotus repo. Just shut down the node, grab the latest code, and rebuild. Filecoin plans to increase chain throughput through the new FIP proposal Molly, an official member of Filecoin, said that the new FIP proposal is in progress. FIP-0005 optimizes Gas usage in attribution calculations to improve chain throughput. Filecoin officially implements the FIP-4 proposal and directly releases 25% block rewards Molly, an official member of Filecoin, announced through the Slack community: Filecoin lotus1.1.0 is currently available, and miners must be at block height 170,000 (about 6:40 on the 23rd Beijing time) score is reached) to complete the upgrade. This version implements the FIP-4 proposal, directly releases 25% of block rewards, and also improves and upgrades the market and API. Ren Zeping: Technology-driven unicorns are mainly driven by high technology such as blockchain, and have the characteristics of natural monopoly: Ren Zeping, chief economist of Evergrande Group, released a report on China's unicorns on the 8th, saying that in terms of innovation forms, unicorns Corned beasts can be mainly divided into platform ecological type and technology-driven type. Among them, the technology-driven type is mainly driven by high technology, such as big data, cloud computing, artificial intelligence, blockchain technology, etc., and most of the representative enterprises are high-tech manufacturing industries. Most of these enterprises are capable of continuous innovation and have the characteristics of natural monopoly, and the key point is to bring differentiation. [2018/4/9] Filecoin has activated the FIP-004 proposal at the block height of 170,000. Golden Finance reported that Filecoin has activated the FIP-004 proposal at the block height of 170,000. Miners who have implemented the latest network upgrade will immediately receive 25% of the block reward. So far, Filecoin miners have produced about 150,000 FIL in the past 24 hours. According to this ratio, Filecoin will issue daily block rewards of more than 40,000 FIL to miners. Filecoin officially answers 6 major market questions including "FIL market making, circulation and miners' strike" Filecoin officially just released a blog post, announcing the Q&A content-zce of the community AMA event. The official has answered relevant questions from netizens on the recent content-zce about Filecoin's "market making", "miners' strike, and the circulation of FIL tokens". 1. About "market making": Protocol Labs has publicly stated that it will use tokens to ensure market stability, buy and sell file coins on exchanges to provide market liquidity, stabilize prices, and correct unbalanced incentives for miners. But to be clear, these are not FIL sales by Protocol Labs. The market-making plan is for the benefit of the community, ensuring liquidity at the beginning of the market and maintaining stable currency prices. 2. Regarding "Protocol Labs team dumping FIL": These allegations are completely false, neither PL nor any team members sold FIL. The controversial FIL in the market is part of the market stabilization plan, mainly to provide liquidity and stability for the market at the initial stage of token issuance. 3. Regarding the "miners' strike": I have not seen any miners shutting down their business, so the official does not describe it as a strike. In fact, the growth of miners is slower than before the mainnet launch. In large part, this is due to the fact that the mainnet no longer subsidizes the cost of staking and fees for miners. 4. In addition to FIP-004, solutions to the miner collateralization problem: A. Space Race 1 and 2 are specifically designed to help onboard miners and bootstrap the network. B.Codefi, Huobi and other companies are developing new lending tools that allow miners to obtain collateral in advance and realize mortgage FIL by sharing their future earnings. C.PL will also support miners through microloans to provide collateral guarantees through third-party providers. 5. Regarding the conversion of testnet tokens to mainnet tokens: In response to Internet rumors that "before the launch of the mainnet, someone bought a large number of testnet tokens, claiming that a member of the official team leaked the token conversion plan and notified the miners." Official I deny this, but the information is official blog public information, and everyone gets the same information. 6. Regarding FIL circulation: The FIL circulation in the market has reached 19,000,000 FIL, and there is no error. Circulating supply comes from three main sources: undisclosed mining rewards, vested SAFT tokens, and tokens reserved for market making and lending (almost all unspent tokens).
