Ethereum co-founder Vitalik Buterin discussed the upcoming steps for Ethereum's Purge, which aims to streamline the protocol and decrease resource loads for nodes. The Purge is a crucial phase in the transition process for Ethereum, involving the removal of outdated network history to simplify the network over time.
By reducing historical data storage, the Purge not only lowers hard disk requirements for node operators but also decreases the technical debt of the Ethereum protocol. Buterin highlighted the implementation of Ethereum Improvement Protocol (EIP)-6780 during the Dencun hard fork as a significant step in simplifying the protocol by eliminating the complexity associated with the "SELFDESTRUCT" code and enhancing security.
Looking ahead, Buterin hopes to introduce a new EIP that entirely eliminates the SELFDESTRUCT function to further streamline the protocol. The Purge will also bring history expiration through EIP-4444, enabling nodes to prune historical blocks older than a year locally. This will reduce the need for historical data storage except during chain synchronization or specific requests.
Notably, Buterin mentioned that by default, storing small amounts of history across nodes could significantly enhance node decentralization. Additionally, Geth has recently removed substantial lines of code post-Dencun, resulting in a storage window reduction to 50 GB for blobs in 18 days.
Buterin also highlighted the importance of purging precompile Ethereum contracts, which are utilized for advanced cryptography not achievable within the Ethereum Virtual Machine. With decreasing demand for these contracts and their role in consensus bugs, eliminating them will enhance EVM implementations.
Overall, the Purge and related improvements aim to drive efficiency and decentralization in the Ethereum ecosystem, paving the way for a more streamlined and secure network.
