Ethereum Pushes for 128-Bit zkEVM Security by Early December

Ethereum's zkEVMs are pushing for higher security standards, aiming to reach demonstrable 128-bit security by early December. Currently, a research contest sponsored by the Ethereum Foundation has shown an unresolved gap of 52.14 bits between the proven results on a cryptographic component called koalaIRS12.

The contest allows researchers to attempt to raise the security bound or attack the parameter, with nine accepted results from seven researchers submitted by August 21. The goal is to gradually reduce the space between the lower and upper bounds, which currently stand at 63.99 bits and 116.13 bits respectively.

While Ethereum's current network does not depend on these proofs yet, zkEVMs will eventually replace the normal consensus operation. In this case, a false proof accepted at layer 1 could have serious consequences, making 128-bit security crucial for the protocol.
