Lu Yang, head of Tencent's blockchain business, said in an interview that another difficulty encountered by the blockchain now is that there are too few related talents. On the one hand, because this is still a very new technology, there are fewer talents studying core technologies. Multi-party consensus mechanisms and consensus algorithms are important development directions of blockchain technology. However, from the domestic and foreign situation, this ability has been in the past two years. The state of slow development has reached a bottleneck period and requires more collective efforts. On the other hand, the lack of cross-border talents who understand both technology and industry makes the efficiency of scene adaptation low.
