What Is ADA? – Cardano Cryptocurrency Explained
ADA: The Native Token of Cardano
ADA is the native cryptocurrency of the Cardano blockchain, a third-generation proof-of-stake platform designed to provide more balanced and sustainable alternatives to existing blockchain networks. The token takes its name from Ada Lovelace, the 19th-century British mathematician widely regarded as the world's first computer programmer. The Cardano project itself is named after Gerolamo Cardano, the 16th-century Italian polymath.
Key Facts:
- ADA is used for transaction fees on the Cardano network
- Staking ADA earns passive rewards (approx. 3-5% annually)
- ADA holders vote on Cardano Improvement Proposals (CIPs)
- Cardano processes transactions with minimal energy use
ADA holders can participate in the Cardano network by staking their tokens to earn rewards or by voting on protocol governance proposals. This design means ADA is both a medium of exchange and a governance instrument. The network's proof-of-stake consensus protocol, called Ouroboros, selects validators proportionally to their stake, enabling energy-efficient transaction processing.
Since the Alonzo hard fork in September 2021, Cardano supports smart contracts, enabling developers to build decentralised applications (dApps) and DeFi protocols on the network. The number of smart contracts on Cardano has grown substantially since launch, and the platform now competes directly with Ethereum and Solana as a smart contract destination.
