Babbitt reported that the "2019 World Blockchain Conference·Wuzhen" hosted by Babbitt was held at the Wuzhen Internet International Convention and Exhibition Center from November 8th to 9th. This morning, at the "D-Future: The Future of Decentralized Finance" sub-forum, Axonomy founder and CEO Tao Quming, DeFi's biggest challenge is the user's cognitive threshold, which is used by less than 10% of the audience at the round table. After DeFi's service (live interaction), then the ratio is even lower in the entire digital currency market. He also pointed out that 90% of users are not using DeFi technology itself, but the new investment and profit opportunities created by DeFi technology. After the emergence of the centralized exchange, Bitcoin developed from the geek circle to the mainstream market, and the wealth effect continued to attract new capital, talents and technology into the blockchain industry, and today's development. Therefore, centralized technology and applications are greatly promoting the development of decentralized technologies and applications.
