[2021/7/2 0:22:41]Ethereum announced the launch of the first phase of the testnet. Ethereum Optimism information shows that Ethereum has launched the first phase of the testnet. The testnet is currently open to the public, but smart contracts have not yet been deployed. , 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. News | Huatong Securities officially completed the acquisition of the blockchain technology platform CTFEX: Yesterday, Huatong Securities officially announced the completion of the acquisition of the blockchain technology platform CTFEX, becoming the world's first licensed securities firm that supports digital currencies. Huatong's official website is now online, and will open its first Hong Kong stock IPO to launch a new project this month. In the first phase, Huatong Securities will open USDT (support for central bank DC/EP and Libra) deposit channels for users to realize interoperability of capital accounts. No need to open a cross-border bank account, no need to exchange currency, just use digital currency, users can invest in global assets with one click. [2019/9/20] Stage C: Withdrawal is allowed. Participants must successfully withdraw coins to get testnet rewards on the mainnet. Ethereum core developer: snap sync begins to enter the final stage of completion Ethereum core developer Péter Szilágyi tweeted that snap sync (snapshot synchronization) has begun 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: Dynamic | The Ningxiang flower pig adoption system based on blockchain technology is online: According to Rednet news, recently, the 2018 China (Ningxiang) Farmers Harvest Festival and the first Ningxiang flower hunting The food festival was held at the Guanshan Huazhu Experience Hall in Ningxiang City, and the Ningxiang Huazhu Adoption System based on blockchain technology was officially launched. The Huazhu adoption system launched on the platform deeply integrates technical means such as "block chain + Internet of Things + artificial intelligence + cloud computing + intelligent anti-counterfeiting" to realize the whole process from young pigs, farms, quarantine departments, slaughterhouses, and logistics enterprises. Industrial chain traceability and tracking. [2018/10/28] 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. News | Shenyang will promote the application of blockchain and other technologies in intellectual property transactions: According to Liaoshen Evening News, Shenyang will build a professional public service platform, improve the comprehensive supporting service system, and promote blockchain and other technologies in intellectual property transactions. , protection and other aspects of the application, to build public technology, comprehensive information, intellectual property transactions and protection, talent exchange and other public service platforms for various market players. [2018/9/16] 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-ethexc 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. News | Bahamas company PO8 uses blockchain technology to unearth underwater artifacts: According to bitcoin reports, Bahamas marine archeology startup PO8 will use blockchain technology in the Bahamas to unearth billions of dollars worth of underwater artifacts, which can be traced back to Spain. Sunken Spanish treasure-laden ship from the Empire period. By using blockchain technology, PO8 will bring complete transparency to all stakeholders including the Commonwealth of the Bahamas. For the past 18 years, the Bahamian government has suspended underwater exploration in its territorial waters due to years of looting, corruption and lack of oversight. [2018/7/7] 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.
