What does Barretenberg do in Noir workflows?

Barretenberg proves Noir circuits from ACIR and witnesses, generates EVM-ready verifiers using ultra_honk scheme—fast, low-mem ZK proofs .

How to deploy Noir proof verifier on Ethereum?

Use bb to gen Verifier.sol, Foundry to deploy via script—load proof binary, set public inputs, call verify(). Works on mainnet/L2s.

Yes—Keccak hashes, precompile pairings keep verify under 1M gas typically; scales better than Plonk on L2s.

📦 Open Source

You've got your Noir circuit compiled. Now? Barretenberg turns it into a verifiable proof anyone can check on Ethereum. No secrets spilled.

Barretenberg turns Noir circuits into EVM-verifiable proofs in seconds, no private inputs exposed. 𝕏
Verification key enables reuse across proofs; Solidity verifier deploys anywhere with precompiles. 𝕏
Workflow (nargo -> bb prove -> Foundry) democratizes on-chain ZK like Unix pipes did computing. 𝕏
