This article analyzes the key content of Ethereum Pectra upgrade: as a major hard fork that collaborates with the execution layer (Prague) and consensus layer (Electra), it contains 11 EIPs, making it one of the upgrades with the largest number of EIPs involved in history. After experiencing setbacks in the upgrade of the test network, the main network is scheduled to be activated on May 7th at 10:05 UTC. The core improvements include optimizing the validator pledge mechanism through EIP-7251, EIP-7002, and EIP-6110 to enhance pledge flexibility and funding efficiency; Utilize EIP-7691 and EIP-7623 to increase Blob throughput and reduce L2 transaction costs; Utilizing EIP-7702 to implement temporary smart contract functionality for EOA accounts and improve user experience; In addition, other EIPs such as EIP-7685 and EIP-2537 have been optimized in cross layer request processing, encryption efficiency, and historical block hash storage, laying the foundation for account abstraction, Layer 2 expansion, and network performance improvement. read the whole passage: https://mp.weixin.
