Cosmos is a decentralized network of independent parallel blockchains powered by BFT consensus algorithms. Being an ecosystem of multiple blockchains, the network can scale up to meet the current traffic needs. Being part of the same ecosystem, Cosmos can guarantee that the transactions are quickly processed and blockchains can maintain sovereignty. Cosmos is making blockchain interoperable. You can see their vision as creating an “Internet of blockchains” in which the individual networks can communicate with each other in a decentralized way.
