Ready to prove Ethereum in seconds on a single GPU?
Introducing ZKsync Airbender:
The world’s fastest open-source RISC-V zkVM ⚡️
On an H100 GPU Airbender reaches ~21.8 MHz base proving speed on a standardised benchmark, followed by 3.45 MHz for SP1 Turbo and 1.1 MHz for RiscZero.
Airbender is ~6x faster than the closest contender.
Powered by Airbender, ZKsync OS (our new zkEVM execution environment) is proving Ethereum blocks end-to-end in under 35 seconds on a single GPU.
This opens the door for truly decentralized at-home proving.
What else does Airbender unlock?
∎ Dramatic cost reduction for ZKsync Chains
∎ Near instant real-time proofs on just a few GPUs
∎ Abundance of GPU compute power for zkApps
∎ Novel use cases in onchain privacy and gaming
∎ Real-time cross-chain coordination
and more.
ZKsync Chains like Era, @AbstractChain, @sophon, @Memento_Bc, @LC, & @grvt_io will use Airbender as a proof system moving forward, reducing proving costs to just $0.0001 per transfer, bringing meaningful savings & performance gains to apps across the Elastic Network.
All parts of Airbender are released as free and open-source (MIT/Apache). The project is in early beta, with internal audits completed.
We can’t wait to see what you’ll build with it!

We’ve released a fun app to showcase Airbender’s capabilities. It’s designed to highlight how this kind of performance feels in practice: from submitting tx to full block proof verification on a ZKsync OS testnet.
