COSMOS is an ecosystem of blockchains that are scalable and interoperable. Before COSMOS, blockchains were often isolated and could not communicate with each other. In addition, they were challenging to build and could only handle a small number of transactions per second.

COSMOS was created to solve these problems with a new technological vision. In scientific terms, COSMOS is a decentralized network of independent parallel blockchains, each powered by BFT consensus algorithms like Tendermint consensus.

COSMOS makes it easy for developers to build anything on a blockchain by breaking down barriers between blockchains while allowing them to transact with each other. The ultimate goal of COSMOS is to create an Internet of Blockchain, a network of interconnected blockchains in a decentralized manner. Once these links are completed, tokens can be seamlessly transferred quickly and securely from one region to another.

ATOM is the base token of the COSMOS Network. The role of the ATOM token is similar to Ether on the Ethereum 2.0 network. In addition, ATOM is also used for the following purposes:

• Users use ATOM to stake, pay gas fees, and transaction fees on the network.
• Validators (or block validators) will be rewarded with ATOM when they keep the network up and running.
