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.
