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. On the afternoon of the 9th, "deciphering the 5G+ blockchain, is it fashionable and practical?" At the roundtable forum, Xue Wei, senior engineer of China Unicom Network Technology Research Institute, said that our understanding of the blockchain is a technology to change the production relationship. It has many features, including traceability and non-tamperability, in fact to establish a long-term credit system and an efficient synergy. So from a relationship perspective, I think that through the blockchain, we can do some internal management optimization and efficiency improvement. In addition, there will be many opportunities for innovative applications. In addition, we may also pay attention to this week, the country has just announced the start of 6G related technology research. In fact, when we talked about 6G networks, there are already some voices, that is, the application of blockchain to future networks and endogenous networks. From the point of view of internal applications, external applications and future evolution, I think this is the starting point for operators to study the blockchain.
