Shenchao TechFlow News, July 6 - Vitalik published a research article proposing a "minimal consensus chain" design approach for Ethereum PoS, combining single-slot finality, recursive STARK signature aggregation, and ZK proofs, shifting a large portion of state management responsibilities to validators themselves.

The plan aims to remove 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 the consensus layer state burden and enabling scaling to millions of validators. The article also proposes submitting daily balance update proofs, validators updating public keys daily to enhance anonymity, and the concept of single secret leader election (SSLE) under this framework.
