$ADA Cardano (ADA) is a decentralized blockchain platform launched in 2017 by Charles Hoskinson, a co-founder of Ethereum. It uses a unique Proof-of-Stake (PoS) system called Ouroboros, which is energy-efficient and supports smart contracts and decentralized applications (dApps). Cardano’s layered architecture enhances security and scalability, while its research-driven approach ensures development through peer-reviewed studies. ADA, the platform’s native cryptocurrency, is used for staking, transaction fees, and governance. With ongoing upgrades, Cardano aims to improve scalability, interoperability, and sustainability, positioning itself as a leading blockchain for secure and advanced digital applications.
