ZKsync's Ethereum Prover Hits Sub-10-Second Proof Speed
ZKsync's Airbender Prime prover proved Ethereum blocks in under 10 seconds, prompting Vitalik Buterin to declare the zkEVM speed race decided. Lido also added native L2 staking via Chainlink CCIP.
If proof speed is no longer the bottleneck, what becomes the real constraint on zkEVM adoption, security audits, formal verification tooling, or simply user trust in unproven cryptography? The answer will shape which Ethereum L2s win developer and user attention over the next year, regardless of whose prover is fastest today. Speed solved one problem, but it did not settle the question of what counts as proven safe.
