$ADA Cardano (ADA) is a third-generation blockchain designed to improve scalability, security, and sustainability compared to Bitcoin and Ethereum. It was founded by Charles Hoskinson, co-founder of Ethereum, and uses a consensus protocol called Ouroboros, based on proof of stake (PoS), making it more energy-efficient. Its development follows a peer-reviewed academic approach, with progressive updates such as the Alonzo era, which introduced smart contracts. ADA, its native cryptocurrency, is used for transactions, staking, and governance. With a strong community and strategic partnerships, Cardano aims to drive decentralized financial solutions, especially in emerging markets like Africa.
