Ethereum Foundation targets quantum resistance for L1 by December 2029
- —Goal is to complete preparation for quantum resistance by December 2029
- —Replacement will affect account signatures, BLS in consensus and KZG in data availability
- —ECDSA signature costs about 4,000 gas, SPHINCS costs 100,000–250,000 gas
- —EIP-8025 with optional execution proofs may be included in Hegotá
Why it matters: The post-quantum transition touches signatures, consensus and execution proofs — it will shape the security and transaction costs of ETH for years to come.
