Aleo is a privacy-first, zero-knowledge Layer-1 blockchain for building fully private applications. Developers write smart contracts in Leo — a purpose-built language for zero-knowledge applications — compile them with snarkVM, and run them on the decentralized snarkOS network, keeping inputs, outputs, and program state private using zk-SNARK proofs while still being publicly verifiable. The ecosystem, developed by Provable (ProvableHQ), includes the Leo language and CLI, the snarkVM zkVM and snarkOS operating system, JavaScript/TypeScript and Python SDKs, a WASM runtime for in-browser proving, the Aleo Explorer, and a public node REST API for reading on-chain state and broadcasting transactions across mainnet and testnet. Aleo is a portfolio company of a16z.
