Cosmos 

One of the most interesting and high potential chains there is. The Cosmos IBC (inter Blockchain Communication protocol) allows any compatible chain to send and receive data. If you imagine blockchains as factories, IBC is like the phone lines that runs between them. Any factory can connect to the phone network by using its specifications and start communicating with other connected factories. This is true for new blockhains, but even existing ones like Ethereum and Polkadot can modify their chains to be able to connect. So in some ways it's like a communication standard that allows everyone to communicate with each other. The cosmos chain is at the center of these connections is also called the relay chain. This is where every message passes through and therefore allows for very exciting features including a DEX and a custodian. It will also offer security features to connected chains, similar to Polkadot's relay chain. Show Less
