1. Development and technology
(1) Ethereum 2.0 technical specification release version 0.12.0 important update
(2) Each validator in ETH2.0 consists of two sets of keys
(3) The Schlesi fork is caused by the mismatch of rewards/punishments between clients
On May 18, Afri Schoedon, a core developer of Ethereum, posted that the Schlesi testnet designed for the public beta of Ethereum 2.0 suddenly forked. This happened on May 17, 2020, slot 141184. This means that a testnet experienced an unexpected split and independently validated different slots. So far, it is the first public fork since the recent launch of the Ethereum 2.0 multi-client testnet.
(4) Topaz, the Ethereum 2.0 test network, has pledged more than 1 million ETH
Ethereum expansion program Matic Network has recently announced the launch of the mainnet. Matic marketing director Chandresh Aharwar revealed that the first round of verification nodes will support staking. Matic is a Plasma-based high-throughput scaling solution for Ethereum, using an improved version of Plasma, PoS-based sidechains. (BeInCrypto)
2. Voice of the Community
(1) V God: skeptical about the "trust model" of some ERC20 tokens anchored on the Ethereum chain
(2) Opinion: The delay of Ethereum 2.0 is caused by many factors, including technical and social scalability requirements
According to Ankitt Gaur, founder and CEO of trading platform Koinfox, who is deploying its proxy protocol on PoS blockchains, the network handling the PoS consensus algorithm is more complex than PoW blockchains in terms of management processes. “Ethereum’s latency is the result of many things. It starts with multiple clients, and those clients have to communicate with each other. The staking process gets more complicated when all validators need to communicate with each other,” he said. "
The Daily Hodl previously posted that the release of Ethereum 2.0 may be delayed again. The constant hunt for code bugs was the main reason for delaying the original January 2020 launch of Plan 0. The "multi-client model" caused delays because human resources were insufficient to ensure optimal development. (Cointelegraph)

1. Slow Mist: Found a new attack method of ETH new fake recharge
On May 22, the SlowMist security team first launched the new ETH fake recharge attack revert method. The SlowMist security team continued to conduct in-depth research and discovered an attack method using Out of gas.
The SlowMist security team suggests: If you are not sure about the successful repair, you can temporarily suspend the recharge request from the contract address first, and then perform the following repair operations:
When using the contract to recharge ETH, it is necessary to determine whether there is a revert transaction in the inline transaction, and if there is a revert transaction, the account will be rejected;
When using the contract for ETH recharge, it is necessary to judge whether there is an Out of gas transaction in the inline transaction, and if there is an Out of gas transaction, the account will be rejected;
When using the contract to recharge ETH, it is necessary to determine whether there is a transaction in the Error field in the inline transaction. If there is a transaction in the Error field, the account will be rejected;
Manual entry is used to process contract entry, and manual entry is performed after confirming that the recharge address has arrived.

3. Analysis: Ponzi schemes and pyramid schemes are currently the largest consumers of Ethereum transaction fees
On May 23, The Block published an analysis article saying that Ponzi schemes and pyramid schemes are now one of the biggest consumers of Ethereum transaction fees. This is due to rising gas prices that have put pressure on legitimate projects, but have barely affected profitable platforms including fraud.
Vitalik Buterin said that while measures like EIP 1559 are aimed at easing the gas price problem in the short term, the real solution lies in improving the scalability of Ethereum.
