London Upgrade Begins to Root With Testnet Implementations Slated to Launch
Three Ethereum testnets will see the London upgrade applied in the near future which shows progress is being made toward implementing the new features. Essentially, the London hard fork is the upgrade that follows the Berlin hard fork that took place in April 2021.
The London hard fork will implement a number of significant Ethereum Improvement Proposals (EIP) in order to prepare for the Serenity (ETH 2.0) upgrade slated for 2022.
- EIP-1559: Fee market change for ETH 1.0 chain
- EIP-3554: Difficulty Bomb Delay to December 1st 2021
- EIP-3198: BASEFEE opcode
- EIP-3529: Reduction in refunds
- EIP-3541: Reject new contracts starting with the 0xEF byte
Ethereum Testnets Ropsten, Goerli and Rinkeby Leave Berlin for London
On Friday, Ethereum core developer Tim Beiko explained that Ropsten, Goerli, and Rinkeby testnets will see the London hard fork implemented during the next few weeks. Beiko said that Ropsten will be the first to launch at block height 10499401, which should take place on June 24. Goerli is expected to go live on June 30 and the Rinkeby testnet is slated for July 7.
