Cardano is a public blockchain platform. It is open-source and decentralized, with consensus achieved using proof of stake. It can facilitate peer-to-peer transactions with its internal cryptocurrency, ADA.[5]

Cardano's development began in 2015, led by Ethereum co-founder Charles Hoskinson. The project is overseen and supervised by the Cardano Foundation based in Zug, Switzerland.[6][7] When launched in 2017, it was the largest cryptocurrency to use a proof-of-stake blockchain, which is seen as a greener alternative to proof-of-work protocols.[8]
