There are two main problems under Interoperability that Cardano wants to solve:
- There are a lot of cryptocurrencies out there, however, they do not work together.
- Government and banks avoid cryptocurrency because they do not adhere to regular banking laws. It's hard for government and banks to trust cryptocurrency because it does not have metadata about the transaction; data like to whom, from whom, and what for.
In order to address these two problems, Cardano envisions to be the “internet of blockchains” or in other words a blockchain that understands what happens inside the other blockchains. Cardano aims to provide a platform where each individual blockchain can communicate with another blockchain and where the user can attach metadata in their transaction “if they want to”.
It is a platform where Bitcoin, Ethereum, and other coins can flow into another blockchain such as NEO without the need to go through central exchanges. Cardano wants to create this through “Cross-chain transfers”.
