Cardano (ADA) is a third-generation blockchain platform focused on creating a secure, scalable, and sustainable ecosystem for decentralized applications (dApps) and smart contracts. Built using a research-driven approach and peer-reviewed scientific principles, Cardano distinguishes itself with its dual-layer architecture, where the Cardano Settlement Layer (CSL) handles transactions with ADA, its native cryptocurrency, while the Cardano Computation Layer (CCL) powers smart contracts and dApp functionalities. This separation enhances both security and scalability, allowing ADA to support complex applications without compromising transaction efficiency. Cardano's unique proof-of-stake consensus mechanism, Ouroboros, reduces energy consumption compared to proof-of-work blockchains, making ADA an environmentally sustainable choice. The Cardano ecosystem is dynamic, with projects spanning DeFi, NFTs, and governance protocols, and is actively developed by a committed community led by Input Output Global (IOG), Cardano Foundation, and Emurgo.
The Alonzo upgrade introduced smart contract capabilities, allowing developers to create dApps on Cardano, expanding its use cases and positioning it for the DeFi and NFT markets.
ADA tokens are released as rewards for staking and securing the network, following a deflationary model as more ADA is staked.
Transactions on Cardano involve transferring ADA from one address to another, recorded on the Cardano Settlement Layer, with confirmations ensuring transaction finality.
Cardano has a capped supply of 45 billion ADA tokens, with about 35 billion currently in circulation.
Once all ADA is issued, transaction fees will serve as incentives for network validators, ensuring sustainable network security without relying on new ADA issuance.
