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). Some zones act as hubs with respect to other zones, allowing many zones to interoperate through a shared hub. 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. 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. While the Cosmos Hub is a multi-asset distributed ledger, there is a special native token called the atom. Atoms have three use cases: as a spam-prevention mechanism, as staking tokens, and as a voting mechanism in governance. As a spam prevention mechanism, Atoms are used to pay fees. The fee may be proportional to the amount of computation required by the transaction, similar to Ethereum’s concept of “gas”. Fee distribution is done in-protocol and a protocol specification is described here. As staking tokens, Atoms can be “bonded” in order to earn block rewards. The economic security of the Cosmos Hub is a function of the amount of Atoms staked. The more Atoms that are collateralized, the more “skin” there is at stake and the higher the cost of attacking the network. Thus, the more Atoms there are bonded, the greater the economic security of the network. Atom holders may govern the Cosmos Hub by voting on proposals with their staked Atoms.
BZ is the ecological token issued by Bit-Z Exchange, abbreviated as BZ. It does not publicly raise funds from investors.The initial stage of BZ is based on the Ethereum ERC20 agreement. In the future, the BZ main net will establish more ecological models to boost the development of the platform. Based on the global eco-development plan of the Bit-Z Group, BZ will have good asset value preservation, expected value-added space, and stable market liquidity. The value space of BZ can be imagined. BZ is bringing a series of ecological core welfare benefits to the Bit-Z Group. 50% of the total, used for global partners to share a new model of dividends. Bit-Z defines one million users as its partners, and is committed to building the world's largest trading platform, and always works with users to promote the new development of global blockchain ecological construction. There is no private equity quota to protect the ecological development of the Bit-Z Group. Bit-Z puts perspective on industry health and platform self-discipline. BZ minimizes the participation threshold for global partners and creates a new economy for welfare sharing. BZ employs third-party data disclosure agencies to share data to global partners in real-time. BZ is committed to creating a fully transparent circulation mechanism.
