Technology Weekly｜Ethereum 2.0 function development will be completed before October 15

This week's Technology Weekly contains technology-related news about the three projects of Ethereum, Polkadot, and Filecoin. V God: We are working hard to reduce Gas fees. Regarding the discussion of high Gas fees, Ethereum founder Vitalik responded: I also hope to end high Gas fees as soon as possible. We are working hard every day to achieve this goal. Ethereum developers: Ethereum 2.0 function development will be completed before October 15 Raul Jordan, an Ethereum developer and co-founder of Prysmatic Labs, said that his team will complete the development of all functions before October 15. Final features currently being developed by Prysmatic Labs and other software development teams include ensuring that Ethereum 2.0 clients are interoperable and can be used interchangeably by users without risking losing validator tokens. (CoinDesk) V God: The new Ethereum 2.0 testnet Medalla node is running well and can fix the disk usage problem Ethereum co-founder Vitalik Buterin said on Twitter that he will upgrade his Lighthouse node on the Ethereum 2.0 testnet Medalla to v0.2.8 , performed very well, and also fixed disk usage issues. If the node is currently taking up a lot of space, upgrading and resyncing can fix that. Lianwen previously reported that the new test network Spadina Launchpad has been activated. Spadina will run in parallel with Medalla for three days starting September 26 for public testing. Heilongjiang's party building work platform supported by blockchain technology is about to go online: the "Digital China Party Building on the Chain" platform developed by the Heilongjiang Academy of Sciences will be officially launched for trial operation. The platform uses the concept of blockchain technology to integrate distributed computing, consensus mechanism, encryption algorithm, smart contract and other technologies. It is understood that the party building platform will test and launch the "Female Party Member Style" section on the "March 8th" International Working Women's Day. At the same time, combined with the needs of party building work during the epidemic prevention and control period, we have successively carried out tests and launched work on sections such as "Like China" and "Applause for Party Members", providing an online platform for Party members to carry out party building work and organize their lives in special times. (Heilongjiang Network Radio and Television Station) [2020/3/6] Ethereum announced the launch of the first phase of the test network Ethereum Optimism information shows that Ethereum has launched the first phase of the test network. The contract, the first stage only contains some features, and the conditions of each stage of the test network are as follows: Stage A: Deposit and withdrawal cannot be performed, token airdrops enter Layer2 Goerli, participants can mint and burn sUSD, and get pledge rewards. Phase B: Coin deposits are allowed. Layer1 Goerli SNX tokens are airdropped to participants. Users who are depositing coins can now increase the amount of SNX pledged. Security exercise: upgrade the OVM smart contract and increase the verification function. Ethereum officials will actively implement fraud (it should mean doing relevant tests) and reward those users who successfully submit fraud proofs. Phase C: Withdrawal is allowed. Participants must successfully withdraw coins to get testnet rewards on the mainnet. Scene | Li Jieli, Senior Director of Ant Financial: Blockchain is one of our core technology applications in the future: Jinse Finance live report, held at the special session of Ant Blockchain Ecological Summit on September 26, released by Li Jieli, Senior Director of Ant Financial Ant Blockchain Partner Program, Li Jieli said that based on the encrypted algorithm network, encrypted credit makes us think that blockchain will be one of our core technology applications in the future. The blockchain requires the participation of multiple parties, and we value openness and win-win cooperation with our partners. In the past year, we have achieved BasS services covering 4 continents, basically achieving global coverage; realized the application of 40+ rich cases, such as commercial bills, judicial dispute evidence collection, etc.; multi-dimensional cooperative enterprises reached 1000+.

[2019/9/26] Ethereum core developer: snap sync enters the final stage of completion Péter Szilágyi, the core developer of Ethereum, tweeted that snap sync (snapshot synchronization) began to enter the final stage of completion. The latest Rinkeby (Ethereum test network) benchmark results are shown in the picture, compared to my last published snap results, the upload is 3 times smaller. Danny Ryan, project leader of Ethereum 2.0: There are certain risks in the pledge after the launch of Phase 0, which is not suitable for everyone. Chase Wright, a network security engineer, issued a series of tweets saying that it is not recommended to pledge ETH when Ethereum 2.0 Phase 0 starts. Chase Wright said that although he was very excited about Ethereum 2.0, the beacon chain and the subsequent progress, he also participated in the Onyx, Witti, Altona and Medalla test networks, and was very familiar with the operation and configuration of the client. Will participate and will not pledge ETH, the reasons are as follows: Voice | Hong Bo: With the support of blockchain and other technologies, insurance companies can conduct safe and efficient processing and analysis: According to China Insurance News, August 17, 2019 , The second "Belt and Road" Medical Rescue Conference was held in Beijing. Hong Bo, deputy general manager of China Taiping Insurance Group, believes that insurance companies hold a large amount of customer personal information, medical history and other data. The "portrait" of the customer is helpful for the accurate deployment of rescue services and medical methods. [2019/8/18] 1. The verifiers of the test network Medalla are still at a loss. Previously, Medalla had a "clock bug" (which has been fixed). If a similar bug occurs on the mainnet, the consequences may be unimaginable; 2. There is a disconnect between the Ethereum 2.0 client team in terms of funding and cooperation; 3. So far, all tests The network is highly centralized. The Ethereum 2.0 test network has only a small number of beacon nodes, and thousands of validators participate through these beacon nodes; 4. There are also inactivity leaks (inactivity leaks, penalties for validators who do not participate in the verification), voting and rewards, etc. question. Even if the node is online and behaves correctly, voting errors may still occur; 5. The return of pledge is fluctuating, and there is no need to lose other opportunity costs for pledge. In response, Danny Ryan, the head of the Ethereum 2.0 project, responded that the pledge after the launch of phase 0 has certain risks and is not suitable for everyone. Testnets are actually very decentralized. Medalla has over 1000 nodes, probably an order of magnitude higher than any other PoS testnet. As for the voting error, Danny Ryan said that after testing, it was found that the current voting accuracy rate is 98%, which will be further improved in the future. Voice | Shang Fulin: State-owned banks should further use blockchain and other technologies to enhance financial service capabilities: According to Xinhua News, recently, at the 17th China Enterprise Development High-Level Forum, Shang Fulin, director of the Economic Committee of the National Committee of the Chinese People's Political Consultative Conference, said that efforts should be made to To enhance the ability of financial services to the real economy, one of the important tasks of large state-owned banks is to further use information technologies such as big data, cloud computing, and blockchain to strengthen the construction of inclusive financial business units and increase the construction of exclusive mechanisms for small and micro enterprises. Improve the ability to standardize, standardize, and facilitate services in key areas and weak links. [2019/1/25] Ethereum EIP 1559 Proposal Progress: Besu and Geth two clients have implemented the proposal On September 23, Ethereum developer Tim Beiko tweeted to update the development process of Ethereum EIP 1559 proposal. The specific content-zce includes: 1. Both Besu and Geth clients have implemented EIP-1559. Multiple implementations can help find bugs, and more client implementations will be added as more complex scenarios are progressively tested. 2. The Ethereum Foundation Robustness Incentives group has been working on agent-based simulations. The simulation was done primarily to analyze how EIP 1559 would respond under a range of different usage patterns. 3. Mechanism design researcher Tim Roughgarden has contracted to evaluate the fee market mechanism proposed by EIP 1559 and will compare other schemes (such as escalator fee scheme). 4. Members of the Ethereum Cat community have begun to contact various projects to seek opinions on the EIP 1559 proposal from outside the community. Finally, for the next step of the proposal, Tim Beiko mentioned that the community will hold the next implementer meeting on October 8. According to the conversation with different stakeholders, the main network preparation list will be formulated for the proposal, as well as more potential clients Proposal implementation. Voice | Dong Mengjun, director of the Public Opinion Center of People’s Daily Online: Use blockchain and other technologies to incubate big data services for people’s finance and economics: According to People’s Daily Online, recently, at the 2018 Media Convergence Development Forum, Executive Director of Public Opinion Data Center of People’s Daily Online and Executive General Manager of People Online Dong Mengjun said that at present, we are incubating the people's financial big data service, which uses blockchain and big data technology to integrate the social evaluation data of public opinion with industrial and commercial, taxation and other data to evaluate a large number of market players. [2018/9/10] Ethereum 2.0 has activated the new test network Spadina Launchpad and completed the audit of the deposit CLI tool Danny Ryan, the project leader of Ethereum 2.0, announced the progress of Ethereum 2.0: 1. The new test network Spadina Launchpad has been activated. Spadina will run in parallel with Medalla for three days starting September 26 for public testing; 2. The security research organization Trail of Bits has completed the audit of the deposit CLI (eth2.0-deposit-cli) tool. In addition, there are many ongoing eth2 client software are also being reviewed; 3. Last week, the phase 0 upgrade proposal EIP 2982 was submitted with Vitalik Buterin. The release of EIP 2982, the final v1.0 mainnet parameters, and the release of the deposit contract (to be discussed) are all milestone events before the mainnet launch. Danny Ryan finally added that the Ethereum 2.0 phase 0 mainnet will be launched soon, and everyone involved is making final preparations. The core developer of Ethereum believes that network sharding has the opportunity to expand more than 10 times before the scalability of Ethereum 1.x. The core developer Alexey Akhunov published a new research direction on the combination of Turbo-Geth and Silkworm. The performance can be expanded by at least 10 times before the chip. Turbo-Geth is a forked Ethereum client Geth client, the core is to focus on performance improvement. Silkworm is a research direction of Ethereum 1.0, in order to further improve the data synchronization performance of the Ethereum network. Akhunov said that I believe that Ethereum 1.0 can be expanded by at least 10 times even without sharding, but there are still challenges: 1. Increasing the gas limit of blocks will lead to DOS attacks, but Turbo-Geth's gas limit is likely to be more secure than other clients 2. Increasing the gas limit of the block may bring about a larger block size, which will cause problems in propagation and storage, but it can be achieved through pre-consensus or using BitTorrent Wait for the dedicated storage network to solve. Polkadot founder: The Kusama parachain auction will be held before the Polkadot parachain auction According to official sources, some community members asked when the Polkadot parachain slot auction will start? Polkadot founder Gavin Wood replied today that the Kusama parachain auction will be held before the Polkadot parachain auction. It doesn’t make sense to start doing auctions until we’re ready to actually host parachains on Kusama/Polkadot. There are several blocking factors as follows: 1. Parachain code needs to be upgraded from Rococo v0 to v1. This work is currently underway and may take a few more weeks. The v1 release is the basis for some important future features including usability and availability, xcmp and parathreading, etc. 2. Cumulus also needs to be upgraded to work with parachains v1 and xcmp-lite and be stabilized (this is also an important stability testing site for Rococo). 3. The ultimate security of parachains (through usability and validity) needs to be fully implemented and (for Polkadot) audited. 4. The auction module also needs to be audited (for Polkadot) (this will take 1-2 weeks, but is unlikely to be a bottleneck). So regarding the slot auction, there is no set date yet, because it doesn't make sense to start an auction before the technical groundwork is done. However, we will continue to update progress whenever important milestones are achieved. Substrate, the basic framework for Polkadot development, released an update Polkadot’s basic framework for blockchain development, Substrate, was updated to v2.0 in the early morning of September 23, Beijing time. The latest version, Substrate v2.0.0 – two dot, is mainly for runtime , client, API, and Runtime Migrations, including the ability to set reward destinations for any account as collateral, update task Grafana dashboards, libp2p client updates, grandpa-rpc api updates, etc. (GitHub) Filecoin: The second round of the space race. Both tracks have specific rewards. On September 24th, Filecoin is officially conducting the AMA event for the second round of the space race. In response to community questions, Filecoin officials stated that there will be a specific reward structure for the two tracks of the second round of the space race. Specifically: 1. For Slingshot, there will be a bonus pool for all storage participants who are eligible for rewards. The size of the bonus pool is determined by the total amount of data stored on the network. The more data that participants collectively store, the larger the reward pool that is unlocked. And the final reward will be distributed among all Slingshot participants in proportion to the amount of data stored in each item.
