Cosmos Network is the network behind Atom (ATOM), which is the primary cryptocurrency on the Cosmos platform, which is designed to facilitate communication, scaling and interoperability between independent channels. Cosmos is looking to consolidate multiple blockchains within a single platform.
Cosmos is a decentralized network of independent parallel blockchains powered by consensus algorithms like Tendermint. Byzantine Fault Tolerance is a feature of a blockchain’s consensus algorithm that allows it to reach consensus in a decentralized environment that could potentially contain malicious consensus check nodes in it.
