Ethereum Layer 2 network ZKsync has announced the launch of the open-source RISC-V zkVM "ZKsync Airbender", which supports fast verification of Ethereum transactions on a single GPU. For example, the "ZKsync Airbender" can achieve a basic verification speed of about 21.8 MHz on H100 GPUs, about 3.45 MHz on SP1 Turbo, and about 1.1 MHz on RisZero, which means that ZKsync OS (ZKsync's zkEVM execution environment) can achieve end-to-end Ethereum block proof on a single GPU in 35 seconds, thereby reducing on-chain costs. It is reported that ZKsync Airbender has completed internal audits and is now in the early testing stage.
