$ADA
Cardano is a popular blockchain platform based on proof of stake, similar to Ethereum. Developers use it to build and deploy custom smart contracts or to create decentralized applications. It is named after the medieval Italian scientist Gerolamo Cardano.
ADA is the native currency of the Cardano network. Its symbol "ADA" stands for the first three letters of Ada Lovelace's name, "the first programmer" in history. You can use ADA to pay network fees, participate in staking consensus, and vote on new proposals related to any updates in the Cardano network.
The Haskell programming language, used in Cardano, is known for its high level of security and reliability. It is used by some of the most prestigious security systems in the world, including banks and military networks.
