A creator-driven, blockchain-based ecosystem for content creation, distribution, and consumption POPCHAIN is a bottom-driven open, public block chain. It is committed to building a block chain 3.0 with supporting services and rapid solutions in creative field. It focuses on block chains and key AI technology such as main node, POP domain name, side chain, consensus mechanism and smart contract. POPCHAIN boasts solid business logic and eco-industrial carrying capacity. It helps enterprises for digital assets and fan economic operation. Consumption scenarios such as content distribution and scene services form an industrial digital asset operating cycle, providing copyright protection, content distribution, IP rights, big data, AI cloud brokerage and other supporting services. POPCHAIN provides a friendly API that allows third-party developers to build their own applications (DAPP) on the basis of their open source protocols. POPCHAIN can be widely used in live broadcast, advertising delivery, code sharing, games and other fields. It revolutionizes and reshapes these areas, So that the center between entertainment developers and consumers no longer dominate resource and value transfer.
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.
