TechFlow reports, on July 6, Vitalik published a research article proposing a "minimalist consensus chain" design approach for Ethereum PoS, combining single-slot finality, recursive STARK signature aggregation, and ZK proofs to shift significant state management responsibilities to the validators themselves.
The proposal aims to eliminate the need for long-term on-chain storage of validator public keys, withdrawal credentials, and most periodic processing logic, retaining only minimal state such as effective balances and deposit tree indices, thereby reducing consensus layer state overhead and enabling scaling to millions of validators. The article also proposes submitting balance update proofs daily, validators updating public keys daily to enhance anonymity, and the concept of implementing Single Secret Leader Election (SSLE) within this framework.
