Vitalik proposes a lean roadmap for the Ethereum consensus chain, aiming to reduce state requirements and enhance validator privacy.

Abstract generation in progress
Wu learned that Vitalik Buterin published a post outlining a path for further streamlining state requirements and enhancing validator privacy in the Ethereum consensus layer under the Lean upgrade, including removing validator public keys from the beacon chain state via STARK-based aggregation, having validators generate STARK proofs daily to update balances, compressing each validator's state to 1 byte of effective balance and 5 bytes of public key index, and reducing the processing burden at the end of each epoch. Vitalik stated that this design could potentially support millions of validators; in an advanced version, validator privacy can be enhanced through daily re-anonymization of validators, ZK-STARK balance update proofs, and hidden withdrawal address commitments, breaking the public link between deposits, staking activities, and withdrawals. This mechanism can also approximately provide Single Secret Leader Election (SSLE); regarding the balance update cycle, 1 hour is the lower bound, while 1 day is more conservative.

Finally someone is seriously working on privacy. It's really ridiculous that public keys are fully exposed.

The design of daily re-anonymization is interesting, but wouldn’t the one-hour minimum be a bit too conservative? Even the L2s are all getting pushed down to the second level.

Hidden withdrawal address commitment → breaking the deposit-withdrawal link—this two-pronged move will leave on-chain analytics firms out of work.

1-byte balance + 5-byte index, that compression ratio is pretty aggressive. How much can it reduce validator hardware pressure?

STARK aggregation on the Beacon Chain, Vitalik is making zk into Ethereum infrastructure.
