Next week, the highly anticipated ethereum mainnet London upgrade will be officially activated at block 1,2965,000 (expected on August 5).
Previously, the three Ethereum testnets Ropsten, Goerli, and Rinkeby have all successfully activated the London upgrade, while the testnet Kovan will be upgraded after the Ethereum mainnet is upgraded.
The London upgrade mainly includes 5 EIPs, namely EIP-1559, EIP-3198, EIP-3529, EIP-3541 and EIP-3554. Among them, EIP-1559 and EIP-3554 have a greater impact. After EIP-1559 is activated, the calculation method of Ethereum’s GAS fee will be changed to basic fee plus tip, and the basic fee will be directly destroyed by the system, and miners will no longer receive the basic fee. This will reduce the circulation of ETH to a certain extent and increase The ecological value of Ethereum, but whether it can fundamentally solve the problems of congestion and high gas fees, it will take time to verify. EIP-3554 mainly involves delaying the time of difficulty bombs. The difficulty bombs have been delayed three times before and are currently tentatively postponed to December 1, 2021. Among other EIPs, EIP-3198 was implemented to assist EIP-1559, with the purpose of returning the basic fee of the current block. After EIP-3541 is implemented, the network will reject new smart contracts starting with 0xEF, and existing smart contracts will not be affected. EIP-3529 modified some operation codes to refund GAS.

The following client versions support the London upgrade of the Ethereum mainnet. The client version of the testnet does not support the London upgrade of the mainnet. Client version.
