ZKsync Launches Airbender, a High-Speed, General-Purpose ZK Prover

TL;DR Airbender delivers the fastest open-source RISC-V zk proofs,sub-second verification for ZKsync blocks, and full proofs in just 3 seconds on a single GPU, boasting a 4–6× speed gain. Proving Ethereum blocks now takes under 35 seconds (17 seconds in lean mode) on one H100, no 50–160 GPU farms required, slashing proof costs to ~$0. 0001. . . source: https://crypto-economy.com/zksync-launches-airbender-a-high-speed-general-purpose-zk-prover/
