Aleo
Aleo   is the first developer platform for building fully private, scalable and cost-effective applications. Using zero-knowledge cryptography, Aleo moves smart contract execution off-chain to enable a diverse range of decentralized applications that are both entirely private and can scale to thousands of transactions per second. Built on an open, public blockchain, Aleo brings all the flexibility of Ethereum but with a more scalable architecture in which miners don’t need to re-run every transaction, but simply verify their correctness.

Aztec
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.
