Noir

Private applications, easy to build.👽 Noir is an open-source programming language for building ZK applications, with familiar Rust-like syntax.

[Noir @NoirLang]

When Noir builders show up, magic happens.

5 talks.
11 workshops.
400 attendees.
100% privacy-pilled.

Thank you for joining us and making NoirCon 3 legendary.

Two commands stand between your Noir circuit and any EVM chain:

bb write_vk -b ./target/program.json -o ./target --oracle_hash keccak

bb write_solidity_verifier -k ./target/vk -o ./target/Verifier.sol

That’s a deployable Solidity verifier contract. Your proofs, verified onchain, on the chains your users already live on.

No install needed — it ships with Nargo (noirup v0.1.4+).

noir-profiler opcodes --artifact-path ./target/program.json --output ./target

A concrete win from the docs: a program zeroing out an array past a dynamic index.

The flamegraph showed dynamic array writes dominating the cost. Moving the writes into an unconstrained function and asserting the result in-circuit: 387 → 284 ACIR opcodes. The flamegraph told you exactly what to fix.

Honoured to be building with @AztecNetwork 🤝

This collaboration is a testament to their world-class engineering — Noir is an outstanding DSL, and the thriving Aztec ecosystem is what makes privacy-first identity truly scalable.

This collab is also a quiet nod to the zkKYC logic we’ve been grinding on for years. Honestly? It’s the best work we’ve ever done — and it’s becoming the foundation for how Web3 identity actually works.

Tomorrow, we’ve got something else to share. Just a little something. 👀

Privacy without identity doesn’t scale. Identity without privacy shouldn’t exist. Compliant privacy is how the real world comes on-chain.

If it's ZK, it's Noir

Noir gets the top billing in this week's Aztec Weekly Recap for our announcement with @solanapayments! 👽

Check it out below 👇

[Aztec @aztecnetwork]

This week on Aztec: Noir goes cross-chain to Solana, operator survey results, new Wonderland collabs, and education to get you building in under a minute. Here's the recap.

[Noir @NoirLang]

Noir is now directly available on @solana!

This is another step on the path towards bringing zk privacy to the masses.

[Solana Payments @solanapayments]

Privacy on @solana comes as three modular options you combine by use case:

- Confidential balances, built into the token program.
- Contra, a state channel for thousands of private transactions with mainnet liquidity intact.
- @NoirLang, @aztecnetwork's zk language, now coming to solana.

[ZKFM @ZKFMradio]

Aztec rewrote their entire protocol in @NoirLang.

It took 10 days.

[Noir @NoirLang]

@ZKFMradio Sounds great! Excited to see it!

[Arnaud Schenk @Arnaudschenk]

If it's ZK, it's Noir.

Really awesome PoC from @iptf_updates

[Savio 👽 @savio_sou]

Built with Noir!

@EwanKrihan @CiaraNightingal @CyfrinUpdraft Hey, that’s awesome!! Congratulations!

[Aztec @aztecnetwork]

Privacy on Ethereum is already here.

Aztec is the L2 that allows developers with no prior cryptography background to build smart contracts with private identity, data, and compute.
