TLDR
A few pioneers are already developing platforms and infrastructures for blockchain interoperability. Cosmos is a decentralized ecosystem of independent blockchains. It uses hub & zone infrastructure for interoperability, where zones represent independent blockchain infrastructure. In Cosmos, anyone can build a zone or a hub — it has no strict rules of membership and they can all connect and exchange data. The project raised 17.6M $ in early 2017 by selling the native currency ATOM in a crowd sale. It has raised 145M $ over 145M+ during its late 2017 crowdsale. Exceeding 200 validators on the network will drop exponentially.via the TL;DR App
