Cardano is a distributed computing platform that runs the blockchain for the Ada cryptocurrency.[3] Bittrex was the first exchange and Daedalus was the first cryptocurrency wallet that holds Ada and allowes transfers to other wallet addresses, but there are more to choose from now.[4]

Cardano blockchain was created by blockchain development firm Input Output Hong Kong (IOHK) and led by Charles Hoskinson, former co-founder of BitShares, Ethereum and Ethereum Classic, and aims to run smart contracts, decentralized applications, side chains, multi-party computation, and metadata.


Coins are minted and decisions are made via a proof-of-stake algorithm called Ouroboros[5] instead of a proof-of-work system; consensus is generated by coin-holder vote. In this protocol, slot leaders generate new blocks in the blockchain and verify the transactions. Anyone holding an Ada coin can become a slot leader.

This staking mechanism makes it unnecessary to brute force the hash code. Thus saves a significant part of the energy required by work-based systems, and allows a resource-efficient and cost-saving blockchain creation.


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 decentralised applications.

This multi-layer architecture allows for easier updates via soft forks than Ethereum does; in Ethereum these two layers are intertwined.


Cardano was released on September 29, 2017 under the 'Byron' bootstrap phase with the official launch in Japan.

Cardano develops their currency around a Recursive InterNetwork Architecture (RINA).[6] Cardano uses Haskell, a programming language with a high degree of fault tolerance.
