$ADA ADA Coin, also known as Cardano, is a popular cryptocurrency that aims to provide a more secure and sustainable blockchain platform. Launched by Ethereum co-founder Charles Hoskinson, Cardano is built on a proof-of-stake consensus mechanism, which is more energy-efficient than traditional proof-of-work systems. The ADA token powers the Cardano network, enabling users to participate in transactions, staking, and governance decisions. With a focus on scalability, security, and sustainability, Cardano has gained attention for its rigorous research-driven approach and ongoing development, positioning itself as a serious contender in the competitive crypto space.
