Babbitt News, November 8-9, the "2019 World Blockchain Conference · Wuzhen" hosted by Babbitt was held at the Wuzhen Internet International Convention and Exhibition Center. On the afternoon of the 9th, "New and Old Dialogue: Where will you and me be in the next decade?" At the roundtable forum, NEO founder Da Hongfei said that the alliance chain and the public chain are at two different levels. If you look at the public chain as a license-free blockchain, that is, you join the blockchain and quit, you don't need a centralized organization to approve or license you to do this business, and the alliance. The chain has certain access and management mechanisms. In fact, these two can be at different levels. For example, in an unlicensed public chain, you can have a smart contract on it, and the blockchain business running on it is exempt. Therefore, the two can coexist. If we look at the Internet, the entire Internet infrastructure is content neutral, I just pass the information, you do not need to be very strong in the face of content and participants at the TCP/IP layer. So I think that in the future, the two can coexist.
