The POC blockchain provides a distributed on-chain identity, storage and transaction system, supports smart contracts and virtual machines in multiple languages, provides two modules of core protocols and application frameworks, and guarantees data security through a consensus mechanism to achieve a complete Centralized blockchain system. The core protocol provides a POC token framework. Around the economic model of proof of contribution value, the cross-chain protocol is used to implement the layer-to-layer and chain-to-chain interaction protocols. The application framework combines the smart contracts on the chain and the off-chain front-end to interact and provides targeted solutions to the chain reform needs of different industries in the real economy.
