Cardano uses a blockchain system that creates free applications and formalizes smart contracts, in its own Plutus language, for maximum security. The Cardano process offers more functionality than competing previously developed networks and represents, in my opinion, a new conception of cryptocurrency. Cardano is open-source, its layered blockchain protocol allows flexibility and is scalable.
The process uses ADA tokens. It’s the very first virtual currency to use the Haskell code. In the context of cryptocurrencies, it ensures the reliability of transactions.
