Cardano is a decentralized public blockchain platform launched in 2017, utilizing a proof-of-stake consensus mechanism and its native cryptocurrency ADA. Co-founded by Charles Hoskinson, a former Ethereum co-founder, Cardano aims to address scalability, interoperability, and regulatory compliance challenges faced by earlier cryptocurrencies.

Governed by three entities—the Cardano Foundation, IOHK, and Emurgo—Cardano distinguishes itself through a focus on scientific research and collaboration with universities. Its development phases, named after notable figures, include Byron, Shelley, Goguen, Basho, and Voltaire, with each phase adding functionalities like decentralization, smart contracts, and governance.
