Aleo

aid: aleo
name: Aleo
description: 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.
