Privacy as a Primitive

" summary

Aztec describes a privacy-first L2 that combines Aztec's privacy-first zkRollup with a split public/private state and local proof generation via kernel circuits, letting users run arbitrary code off-chain and submit succinct ZK proofs on-chain. Contracts are written in the Noir programming language, with unlimited runtime for private transactions, Touch ID account abstraction, and targets like a six–contract DeFi proof on mobile in under 30 seconds (basic payments under a few seconds). A sandbox v1 exists (Sept launch) and a decentralized testnet aims for Q3 2024.
