Ethereum May Adopt Optional ZK Proofs for Block Validation

Ethereum is preparing a shift that could replace transaction re-execution with zero-knowledge (ZK) proofs for block verification. The change centers on EIP-8025 (Optional Execution Proofs), which enables certain validators, called zkAttesters, to confirm blocks using cryptographic proofs rather than re-running every transaction.

Ladislaus.eth described the upgrade as "arguably one of the more consequential" in the network’s history. The proposal is optional, so existing nodes and consensus continue to operate as they do today while adopters gain faster validation. ZK proofs let zkAttesters verify a block almost instantly without storing the entire chain, and they lower hardware, storage, and bandwidth requirements.

That reduction could allow solo stakers and home validators to participate using regular consumer hardware, preserving decentralization and the "don't trust, verify" philosophy.
