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 standardized 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! Start using Airbender today:

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. Try your hand at racing Airbender:

This thread just scratches the surface of Airbender. Read the full blog post for benchmarks, a technical deep dive, and what it means for the future of proving:
