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
Thatβs a deployable Solidity verifier contract. Your proofs, verified onchain, on the chains your users already live on.
Guide β https://t.co/MVFNcfp37L
No install needed β 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 β 284 ACIR opcodes. The flamegraph told you exactly what to fix.
Honoured to be building with @AztecNetwork π€
This collaboration is a testament to their world-class engineering β 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 weβve been grinding on for years. Honestly? Itβs the best work weβve ever done β and itβs becoming the foundation for how Web3 identity actually works.
Tomorrow, weβve got something else to share. Just a little something. π
Privacy without identity doesnβt scale. Identity without privacy shouldnβt exist. Compliant privacy is how the real world comes on-chain.
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.
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.
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.
