Cardano (ADA) is a digital currency that relies on blockchain technology and is known for its focus on academic research and scientific review. It was developed to provide a smart and secure platform that supports smart contracts and decentralized applications (dApps). Cardano is characterized by its high efficiency and low energy consumption thanks to the proof-of-stake (PoS) mechanism it uses, known as Ouroboros. Cardano aims to improve financial inclusion in developing countries and provide a reliable digital infrastructure for institutions. Despite market fluctuations, Cardano remains a long-term project trusted by many due to its scientific vision and sustainable approach to blockchain development.
