Cardano blockchain is a third-generation blockchain platform known for its scientific approach, scalability, and sustainability. Developed through peer-reviewed research, it supports smart contracts and decentralized applications (dApps) with a focus on security and energy efficiency. Using the Ouroboros proof-of-stake consensus protocol, Cardano offers faster transactions and reduced environmental impact. It enables features like identity management, supply chain transparency, and DeFi services. Cardano aims to bridge the gap between academic research and blockchain innovation, providing a secure and scalable foundation for future decentralized technologies.
