Cosmos (ATOM) is a decentralized network that aims to address common issues in the blockchain industry. It offers a solution to the limitations of proof-of-work protocols, such as slow transaction speeds, high costs, scalability issues, and environmental impact. The ATOM tokens, which are obtained through a hybrid Proof-of-Stake algorithm, play a crucial role in maintaining the security of the Cosmos Hub, the project's primary blockchain, and the network's governance.
