Offchain Labs released an update to the Ethereum client Prysm on Capella and EIP-4844. The Prysm team has now implemented and reviewed all core functions that support withdrawals in Capella upgrades in the default branch "develop" of Github, and is designing to handle extreme cases such as broadcasting BLSToExecutionChange messages before and after forks, extending the CLI tool prysmctl provided by Prysm, and improving User withdrawal experience. At the same time, Devnet3 is running smoothly, and the validator exit test is completed. Devnet 4, 5, 6 were launched at the interop conference last week of January, testing validator credential changes with a mainnet-sized validator list. The team also successfully completed a shadow fork with a Devnet3 configuration on the Sepolia testnet. Testnets such as Goerli and Sepolia will also launch withdrawals in the coming weeks. During the interoperability meeting, the team started the EIP-4844 devnet and solved many problems, re-wrote the new KZG encryption library to support blob transaction security, and it is expected to be put into use in the next few weeks. The KZG library also switched the backend go-kzg Gnark for the audit in the next month and a half. In terms of the execution layer, the design of the blob transaction mempool is becoming more and more mature, and solves the coupling and decoupling problem between blocks and blobs in the consensus layer, but new specification changes and client implementations are still required.
