ADA

Cardano is a blockchain platform designed for smart contract applications, token issuance, and decentralized services. Its native asset, ADA, is used for transaction fees and staking within the network. The project positions itself as a research-driven Layer 1, with development informed by academic methods and peer-reviewed design choices.

Technically, Cardano uses a PoS consensus mechanism called Ouroboros, which is intended to support network security and energy efficiency compared with PoW systems. The architecture separates the settlement layer from the computation layer, a structure that is meant to improve flexibility for smart contract execution and protocol upgrades. This design also supports staking participation through delegated pools.

In practice, Cardano is used for DeFi, NFT issuance, identity-related tools, and other applications that rely on smart contract functionality. Its ecosystem includes wallets, staking infrastructure, developer tools, and a growing set of dApps. Within the broader market, Cardano is often viewed as an established Layer 1 competing with other general-purpose blockchains on scalability, governance, and application development.
