Project chain is a decentralized project application platform. It will provide a series of SDKs, APIs, and front-end programs to help users build decentralized applications based on JavaScript and side chain technology. The project chain is committed to creating an easy-to-use, fully functional, and plug and play system by providing integrated project industry solutions such as customized side chains, smart contracts, and application hosting. By utilizing the project ecosystem, project enterprises can quickly build their own blockchain, issue tokens, select smart contract sets, and build and publish domain DAPPs suitable for their own use. The entire process will be ensured by an honest and secure project main chain and side chain consensus network. In order to support a high concurrency trading environment in new fields and achieve maximum decentralization, Project Chain (PRCC) creatively proposed a blockchain solution that combines main chain and side chain, organically running. The main chain of the project chain adopts a strong consensus POS consensus mechanism, including a token issuance system and a complete main side chain communication mechanism. The side chain adopts an efficient DCD consensus mechanism and runs a smart contract set for project domain business on the side chain. In this structure, each project enterprise will have an independent side chain, which ensures the efficient operation of each subsystem while not affecting the performance and security of the main chain of the project chain. This enables the project chain digital asset ecosystem to achieve high scalability, sufficient to support the performance requirements of the blockchain in the project field....
