ADA is a coin of the Cardano project, which some time ago was called the "potential killer of Etherium". The project is developing an advanced, decentralized platform of secure and easily scalable smart contracts.
Cardano is being developed long, complex, with scandals, and other attributes of a large scientific project with decentralized management and inflated expectations of investors. The project team consists of several groups of developers. Objectively speaking, some of the best specialists are working on the project.
Cardano blockchain is based on the proof-of-stake consensus algorithm Ouroboros.

Everything about this project is hard to describe in simple words, so we will return to ADA coin, which is traded on most major crypto exchanges.
