$ADA Ada coin, or ADA, is the native cryptocurrency of the Cardano blockchain platform, designed to offer a scalable and secure environment for smart contracts and decentralized applications. Developed by IOHK (Input Output Hong Kong), Cardano focuses on a scientific, research-driven approach to blockchain technology. The Ouroboros consensus protocol, based on Proof-of-Stake (PoS), ensures energy efficiency and decentralization. ADA coins are used for transaction fees, staking, and governance. Staking allows users to earn rewards, while governance gives them a voice in protocol upgrades. With its commitment to scalability, sustainability, and inclusivity, Cardano aims to offer a more efficient alternative to traditional financial systems and blockchain platforms.
