Vitalik Buterin has proposed Ethereum Improvement Proposal (EIP) 7864, which aims to remove the current contract size limit on the Ethereum network. The existing cap is designed to prevent denial-of-service (DoS) attacks, but the new proposal suggests implementing 'infinite-sized contracts' through a unified binary tree structure. Buterin acknowledged that while this change could facilitate larger contract deployments, it does not address the associated gas cost challenges. Additionally, he highlighted that the 'stack too deep' issue should be resolved at the programming language level, rather than through network protocol changes.
