Cardano is a decentralised public blockchain and cryptocurrency project and is fully open source. Cardano is developing a smart contract platform which seeks to deliver more advanced features than any protocol previously developed. The Ada cryptocurrency operates on its own blockchain called the Cardano Settlement Layer (CSL). The CSL is an accounting layer and supports ledger transactions. A second layer, called the Cardano Computation Layer (CCL), will support smart contracts and decentralized applications.
