Cryptocurrency ADA is the currency of the Cardano protocol, which can be used to send and receive digital funds. This digital cash represents the future of money and makes it possible to ensure secure and fast direct transfers through encryption technology. Cardano is not only a cryptocurrency, but also a technology platform that will be able to run the financial applications currently used by individuals, organizations and governments around the world. The platform is built in layers, which makes the system more flexible and easy to maintain, and allows upgrading through soft fork. After the settlement layer that will run ADA is completed, a separate computing layer will be established to process smart contracts. These digital legal protocols will provide support for future businesses and businesses. Cardano will also run distributed applications or dapps services, which are not controlled by any party, but run on the blockchain. This is the first blockchain project developed according to scientific principles and the only project designed and built by a team of leading scholars and engineers in the world. The technology must be secure, flexible and scalable for millions of users. Therefore, a lot of ideas and care from some leading experts in this field have been put into the project and made wise design decisions. The scientific rigor applied to mission critical systems such as aerospace and banking has been brought into the field of cryptocurrency and has a high degree of implementation. We think this is the first time. A major innovation of Cardano is that it will balance the needs of users and regulators, and combine privacy and regulation. Caldano's vision is that its new standardized computing will bring greater financial inclusiveness through open channels to provide fair financial services for all.
