The frequency of changes has dropped significantly.

https://twitter.com/ (1) V God introduces the first hard fork upgrade proposal "HF1" of the Ethereum Beacon Chain

Vitalik, the founder of Ethereum, introduced the upgrade proposal of the first hard fork of the Ethereum Beacon Chain (tentatively named "HF1") on Twitter. V God said that HF1 added light client support, simplified the specification, improved efficiency, and introduced a less punitive inactive leak mechanism. According to the document, the hard fork will allow developers to make some key upgrades to the recently released beacon chain and will also serve as a useful test for deeper changes in the future. Among them, light clients support nodes that have the lowest requirements on resources and can run on mobile devices. This would allow "trust-minimized wallets" to verify the blockchain themselves, rather than relying on external service providers.

According to the content of the Ethereum core developer meeting, developers plan to upgrade the Berlin hard fork at block height 12244000 on April 14. This upgrade includes various optimizations to the contract, including gas efficiency, an update to the code reading method of the Ethereum Virtual Machine (EVM), and prevention of DDOS attacks, etc., aiming to realize the real-time conversion from the PoW chain to the PoS chain. The Berlin hard fork was initially planned for June or July 2020, but was ultimately delayed, mainly due to centralization issues surrounding the Geth client on which most Ethereum nodes run. There will be multiple testnets before the Berlin hard fork upgrade. The upgrade includes at least five EIPs: EIP-2565, EIP-2315, EIP-2929, EIP-2718, and EIP-2930, and will be released on four Ethereum test networks before deployment. (CoinDesk)

(1) Ethereum Cat Shepherd will organize a community conference call to discuss the implementation of EIP-1559

On February 26th at 14:00 (UTC), Ethereum Cat Herders will organize a community call to discuss the implementation of EIP-1559. Key participants of the conference include: EIP advocate researchers, developers and miners from the Ethereum community. After a brief overview, the panel will discuss concerns miners have raised about the EIP, discuss related development and research updates, and answer questions submitted by the community. The moderator is Hudson Jameson, community manager of the Ethereum Foundation. Speakers include: Ethereum developer Tim Beiko, Ethereum developer Rick Dudley, EIP editor Micah Zoltu, crypto researchers Barnabé Monnot, Hasu and Georgios Konstantopoulos,

Client developer Tomasz K. Stańczak, network upgrade coordinator James Hancock, miners Wang Chun (F2Pool), BitsBeTrippin (Independent) and Chris K. (Flexpool.io), and community staff Aftab (DC Investor).

Julian Koh, an employee of Coinbase Custody, said that he will create a new programming language for Ethereum and write all the code in this new language to make it unforkable.

(1) Badger DAO has been launched on ZK Rollup expansion solution StarkNet

Zero-knowledge proof research and development organization StarkWare stated that the decentralized autonomous organization Badger DAO (BADGER) has launched its second-layer expansion solution ZK Rollup "StarkNet".

StarkNet is a decentralized two-layer ZK Rollup driven by STARK, which can support the general computing of Ethereum. At present, the basic construction (phase 0) has been completed, that is, the Turing complete framework Cairo, the STARK software stack and the two-layer expansion engine StarkEx. Phases one through three will be built.

(2) Ribbon Finance is officially launched, launching the first multi-protocol wide-span option on Ethereum

(3) Ethereum non-destructive lottery PoolTogether releases governance tokens and will airdrop 1.4 million tokens

The Ethereum non-destructive lottery project PoolTogether released the governance token POOL, and airdropped 14% of the total tokens to users before January 14. The total amount of PoolTogether tokens is 10 million. Of the token distribution, 80.04% are allocated to the community, 12.44% are allocated to consultants and employees (locked for one year), and 7.52% are allocated to investors (locked for one year). PoolTogether airdropped a total of 1.4 million Pool tokens to users before January 14, 2021, accounting for 14% of the total, and they are already available for collection. PoolTogether will also distribute 5% of the tokens to users of each lottery pool for 14 weeks starting on February 17.

According to official news, Celer Network, the second-layer expansion project of Ethereum, launched Layer2.finance, a DeFi expansion and speed-up solution based on Optimistic Rollup, which aims to use Layer 2 rollup in different ways, similar to any rollup, and users can use rollup on Layer 1 The contract conducts a deposit transaction to deposit funds into the rollup chain of Layer2.finance, but Layer2.finance will not migrate the DeFi protocol itself to Layer2. Layer2.finance builds a model similar to a decentralized intermediary. Users store funds on the Layer 2 chain, and through a special Layer 2 transaction (transaction), indicate which DeFi protocol their funds want to be placed in. Layer2.finance plans to launch version 1.0 in the first quarter of 2021, upgrade to ZK Rollup after the initial stage of iteration, and will support protocols such as Curve, yEarn, Compound, and Aave in version 1.0.

According to data from OKLink, from February to now, the income of miners on Ethereum has reached 790 million US dollars, exceeding the 760 million US dollars of Bitcoin in the same period. Additionally, 53% of Ethereum miners’ revenue comes from network transaction fees, compared to 14% for Bitcoin during the same period.
