Winchain is a national-level blockchain-based lottery system for global markets, which is created by top technologists from the international lottery industry and the global blockchain industry. The public-chain serves as the base of the bookkeeper election mechanism. Because public-chain is completely open, more people can participate in the node registration and bookkeeping of the consortium-chain and get their rewards accordingly; the consortium-chain functions as the underlying technology platform of the lottery system. By combining the public and consortium blockchain networks together, the decentralization of rights, bookkeeping, and transactions are well achieved on the ecosystem whilst decentralized lottery games can enjoy an instantaneous performance on Winchain at a very low cost.
