Aztec is a privacy-first Layer 2 rollup for Ethereum that enables encrypted transaction execution and private smart contracts while maintaining public verifiability through zero-knowledge proofs. Unlike privacy blockchains like Zcash, Aztec is programmable—developers can specify privacy at granular levels (users, data, metadata, or full contract logic) using the Noir language. It uses client-side proof generation to keep sensitive data off centralized servers, enabling institutions and users to conduct confidential DeFi operations on Ethereum.
