Babbitt reported on the 8th, November 8th, 2019 World Blockchain Conference·Wuzhen officially opened at Wuzhen Internet International Convention and Exhibition Center. In the afternoon “Technology Unbounded: Blockchain Underlying Infrastructure” sub-forum, ViaBTCCoinEx founder Yang Haipo said that Token is the core application of the blockchain. He believes that Token is a proof of rights and that the issuance of Token has become the standard of the major public chains, which has brought the exchange's prosperity. Centralized exchanges have problems such as insecurity, opacity, and high marginal cost of the currency. Decentralized exchanges (DEX) can solve these problems. He also pointed out that the decentralized exchange is the infrastructure of the future blockchain, because DEX does not require permission to release the long tail Token, greatly expanding the boundaries of the entire blockchain world. DEX is the direction of the next generation of palace chains and can release trillions of market space.
