Overview
Cardano is a Proof of Stake blockchain built using formally verified, peer-reviewed research, founded by Charles Hoskinson (co-founder of Ethereum) via IOHK. It uses the Ouroboros PoS protocol, the first PoS consensus mechanism proven cryptographically secure in an academic paper. Cardano emphasizes rigorous formal methods, extended UTXO (eUTXO) model, and a phased roadmap — it is one of the few blockchains with a published academic research foundation for each protocol upgrade.
Who Created ADA?
Cardano was created by Charles Hoskinson and launched in 2017. It is a Layer 1 cryptocurrency using Proof of Stake (Ouroboros) consensus.
Key Use Cases
Cardano targets developing nations and underbanked populations with identity, academic credential, and supply chain verification use cases, particularly in Africa through IOHK's partnerships in Ethiopia (Atala PRISM for 5 million student IDs) and other countries. DeFi protocols including Minswap, Indigo, and Liqwid Finance provide native DeFi on Cardano for ADA holders.
Key Features
- +Ouroboros PoS — the only PoS consensus algorithm proven secure through peer-reviewed academic paper
- +eUTXO model enables deterministic transaction execution — no surprise gas fee failures
- +On-chain governance via CIP-1694 — ADA holders vote directly on protocol parameters and treasury spending
- +Native token standard does not require smart contracts — cheaper and safer than ERC-20
- +IOHK's Africa partnerships: 5 million Ethiopian student IDs on-chain via Atala PRISM
- +Hydra state channels scale to 1M TPS per head while settling on Cardano mainnet
