Cardano's main objective is to become a base platform for creating decentralized applications (dApps). Therefore, Cardano offers its chain for the creation of tokens and smart contracts for anyone who wants it.
Likewise, IOHK also tries to make its currency prioritize interoperability in its services. In other words, the ability of the products created within Cardano to be compatible with other Platforms.
Since its founding, Cardano has gone through five distinct stages: Byron, Shelley, Goguen, Basho, and Voltaire. In each of these he has focused on the development of an edge of his Blockchain. The phases overlap in time, as part of the complementarity that was sought by deepening each one.
The first two phases laid the cornerstone of the project. Byron meant the founding of Cardano and the commissioning of its platform. For his part, Shelley focused on decentralization, transferring system nodes to the community, from IOHK. Likewise, the following two stages were aimed at creating the ecosystem on which Cardano is based. While Goguen led to the introduction of smart contracts within the platform. Allowing the creation of dApps and other functionalities. Basho focused on the scalability of the blockchain.
In this way, Cardano introduces an innovative element to the crypto world: the side chains. These would be blockchains that would run simultaneously to the main Blockchain, allowing to avoid bottlenecks in it. Transactions taking place on these secondary chains, while the main one is released.
