Aztec uses bleeding-edge cryptography to enable private, programmable transactions on top of the Ethereum blockchain protocol.
Our in-house zk-snark protocol, plonk, is rapidly converging to become an industry standard, used by many companies and projects in the blockchain space.
One of our flagship projects is Noir, an open-source zk-snark programming language. Noir exposes a high-level rust-like programming language, that compiles into a zero-knowledge circuit using our plonk backend software. We plan on supporting multiple cryptographic backends in the future.
zk-snark programming languages present some unique challenges, due to the constraints of compiling a high-level program into a cryptographic protocol.

With public keys exposed between trade partners, open blockchain networks are not private enough for safe use by citizens, corporations, and financial institutions. Current privacy solutions protect individuals but lack the compliance and regulation needed for commerce. Vendible couples identity to assets to manage compliance while leveraging privacy-preserving features to protect data and transactions. Our wallet infrastructure will allow both Vendible, developers, and companies to build applications that drive value while protecting consumer identity and data. From an unbanked individual to a Fortune 500 company, all members receive rewards for depositing assets into our ecosystem.
