Ethereum researchers are racing to close a zkEVM security gap before December
Ethereum’s better.codes contest now measures a cryptographic proof gap that researchers can attack from both sides. At 15:44:47 UTC on Aug. 21, the live leaderboard showed a 63.99-bit lower certificate and a 116.13-bit upper certificate for koalaIRS12. The two results left 52.14 bits unresolved after nine promoted submissions from seven solvers. KoalaIRS12 is a fixed…
