Cardano is a proof-of-stake blockchain platform that says its goal is to allow “changemakers, innovators and visionaries” to bring about positive global change.
Cardano was founded by Charles Hoskinson, who was also one of the co-founders of the Ethereum network. He is the CEO of IOHK, the company that built Cardano’s blockchain.
Cardano is one of the biggest blockchains to successfully use a proof-of-stake consensus mechanism, which is less energy intensive than the proof-of-work algorithm relied upon by Bitcoin.
