Tokenview dataIt shows that the number of transfers on the chain decreased slightly last week, the number of large-value transfers of "above 5,000 ETH" and "above 10,000 ETH" decreased by 21% and 10% month-on-month respectively, and the number of transfers of "above 50,000 ETH" increased by 31% month-on-month. The frequency of giant whale account transactions has increased significantly.

EIP-1559 is officially included in the Ethereum "London" hard fork upgrade
On March 3, the Ethereum programming language Solidity team released version 0.8.2, adding an optimization stage that can inline a small amount of code to save Gas, and provide more ways to export inline comments and allow custom natspec tags Use code documentation. Inlining is an optimization technique that expands the function body directly to the call site.

(1) Wu Jihan: If EIP-1559 is successfully passed, the price of ETH will rise sharply
In response to the opposition of a large number of mining pools to the EIP-1559 proposal, Jihan Wu, chairman of BitDeer, said that V God has worked so hard to make such a good proposal, and there are still so many people who oppose it. The proposal passed smoothly, the price of ETH rose sharply, and the miners were also winners. EIP-1559 will destroy most of the fees, promote Ethereum from inflation to deflation, and reduce the income of miners (coin standard) by 10-30%. At present, Xinghuo and other Ethereum mining pools are against it, but F2Pool supports it, believing that it can improve user experience.
(2) Ethereum Cat Shepherd project management staff: With the repair of the ice age, I hope that miners without EIP-1559 will not be able to perform simple chain forks
Edson Ayllon, project manager of Ethereum Cat Shepherd and contributor to the Ethereum ecosystem, said that EIP-1559 will be launched in the Ethereum London network upgrade, and will also fix the upcoming Ice Age (Ice Age). Hopefully, miners without EIP-1559 will not be able to do a simple chain fork, but will need to assign new clients after the Ice Age is lifted.
It is reported that Ethereum’s Ice Age is an adjustment strategy for the difficulty of Ethereum’s PoW mechanism. The difficulty adjustment of PoW in Ethereum will continue to increase according to the block height, and this increase is exponential, and the speed of computing power development will be far behind the speed of difficulty increase. Ethereum cannot enter the ice age, and entering the ice age means that Ethereum will lose its function. Ethereum set the ice age to show its attitude and determination to switch to PoS.

(1) Encryption wallet MetaMask releases security tool LavaMoat
On March 1, it was officially announced that the encryption wallet MetaMask released the security tool LavaMoat, which can avoid previous Hardhat-type attacks. According to MetaMask, LavaMoat is a set of tools used to protect projects from malicious code in the software supply chain.
(2) Compound launched the Gateway testnet
The Compound team announced the launch of a prototype based on the Compound Chain white paper called Gateway. Gateway is a Substrate blockchain governed by COMP token holders on Ethereum. Starting today, Gateway will operate as a testnet and connect to Ethereum’s Ropsten testnet. Compound Finance founder Robert Leshner said the testnet is expected to run for two months before it is fully launched. It is reported that the Compound team released the Compound Chain white paper three months ago. The announcement describes Compound Chain as a "distributed ledger capable of transferring value and liquidity between peer ledgers." (CoinDesk)
On March 2, the Ethereum ZK Rollup expansion solution Hermez Network announced the launch of the public test network, which will support the last round of private testing. The main network is expected to be launched in the next few days. Currently, testnet features include a mobile and web wallet to interact with Hermez ZK Rollup user accounts, developer SDK and API integration, and Hermez Layer 2 batch browser.
It is reported that Hermez was launched by iden3, the Ethereum expansion solution technology team. According to the white paper, Hermez allows payments and token transfers to scale on top of the Ethereum public blockchain.
(4) Oddz Finance, a multi-chain options trading platform, released a white paper
Oddz Finance, a multi-chain options trading platform based on BSC, Polkadot and Ethereum, released a white paper. The white paper outlines the details of technical breakthroughs in derivatives trading, exercising option contracts, liquidity mining, token utility, and protocol governance, providing a comprehensive outlook on the Oddz Finance ecosystem.
(5) Arbitrum, the expansion project of Ethereum, gave up its patent and will launch the mainnet soon
Arbitrum, the Ethereum expansion project, stated that considering that the project has entered the mature stage of the community, it will abandon its patents and is currently waiting for the approval of Princeton University. In addition, Arbitrum will be launched on the main network soon. Originally an academic project at Princeton University, Arbitrum previously disclosed its intentions to commercialize the technology, which was later patented with Princeton support.
OpenSea's official website shows that the Associated Press (AP) and Everipedia have collaborated with the famous digital artist Marko Stanojevic to create an NFT artwork "A View from Outer Space" commemorating the first report on the US election on the blockchain. The work will be auctioned on OpenSea for 7 days starting from March 3, and all bidding prices are priced in Ethereum. It is understood that the art work was designed by internationally renowned digital artist Marko Stanojevic, who has worked for Avicii, Alan Walker, Alesso, Axwell & Ingrosso, as well as Pepsi and McDonald's, etc. The brand has created music videos, live visuals and artwork.
