Ethereum weighs hash functions: BLAKE3 fastest, SHA-3 safest
- —BLAKE3 is fastest on long messages; SHA-3 is the slowest of the main candidates
- —SHA-3 ranks first on risk minimization, followed by BLAKE2s and an SHA-2 variant
- —The Flock proof system removed the need for circuit-friendly hashes, widening the field
- —The Ethereum Foundation targets post-quantum L1 security by December 2029
Why it matters: Changing hash primitives affects consensus, the state tree and zkVM proofs, shaping Ethereum's post-quantum security roadmap.
