To learn more about Cosmos Hub (ATOM), you may: Thus, the more Atoms there are bonded, the greater the economic security of the network.Ītom holders may govern the Cosmos Hub by voting on proposals with their staked Atoms. The more Atoms that are collateralized, the more “skin” there is at stake and the higher the cost of attacking the network. The economic security of the Cosmos Hub is a function of the amount of Atoms staked. Fee distribution is done in-protocol and a protocol specification is described here.Īs staking tokens, Atoms can be “bonded” in order to earn block rewards. The fee may be proportional to the amount of computation required by the transaction, similar to Ethereum’s concept of “gas”. Atoms have three use cases: as a spam-prevention mechanism, as staking tokens, and as a voting mechanism in governance.Īs a spam prevention mechanism, Atoms are used to pay fees.
While the Cosmos Hub is a multi-asset distributed ledger, there is a special native token called the atom. By creating a new zone, you can plug any blockchain system into the Cosmos hub and pass tokens back and forth between those zones, without the need for an intermediary. The architecture is a more general application of the Bitcoin sidechains concept, using classic BFT and Proof-of-Stake algorithms, instead of Proof-of-Work.Cosmos can interoperate with multiple other applications and cryptocurrencies, something other blockchains can’t do well. Some zones act as hubs with respect to other zones, allowing many zones to interoperate through a shared hub.
The Cosmos network consists of many independent, parallel blockchains, called zones, each powered by classical Byzantine fault-tolerant (BFT) consensus protocols like Tendermint (already used by platforms like ErisDB).
