GTSE (Global tourism sharing ecology, Xinyou Chain) uses a dual-token economic model as an incentive for ecological nodes. Established an on-chain payment ecosystem with the alliance chain as the underlying technology, smart contracts as the starting point, and DAPP as the application portal, while focusing on the application and development of offline scenarios. On the basis of solving the pain points of the traditional tourism industry, let all ecological nodes work together to play a synergistic effect, contribute to ecological growth, promote the explosion of the huge potential of the "blockchain + tourism" new industry, and create a truly decentralized, valuable A shared and ecologically resonant OTA ecosystem on the distributed chain.
