Dr. Yuan first proposed SHD completeness. In En-Tan-Mo blockchain, Dr. Yuan builds UPoS-based Kantorovich consensus which guarantees the separation of token owners and mining machines as well as their respective stakes and interests via a miner election mechanism. Hence En-Tan-Mo achieves SHD completeness as efficiency is drastically enhanced without undermining security and decentralization is maintained.
At En-Tan-Mo, Dr. Wang constructs the multi-chain structure composed of a central chain and derived chains. The parallel chain interaction protocol that underlies the central chain enables two-way asset transfer between central chain and derived chains, between different derived chains and between derived chains and other blockchains. Thus, it provides a fundamental solution to high concurrency and congestion, two serious impediments to blockchain’s development.
