Cardano is a blockchain built by IOG (Input Output), led by Ethereum co-founder Charles Hoskinson; it started in September 2017. It uses Ouroboros, a proof-of-stake protocol proven in peer-reviewed papers, and extends a Bitcoin-like model (UTXO) to handle smart contracts.
Smart contracts (Plutus) have run since September 2021, and since 2024 ADA holders vote on the chain’s direction through on-chain governance. ADA is its own coin.
