Liu Xiaodong, vice president of Lianmao Digital Technology, said that the use of blockchain technology can solve problems such as data exchange and process optimization. As long as the blockchain technology is reasonably applied to the current business scenario, the technology itself may be possible for all business industries. Both are opportunities, and the same is true for the payment industry. Compared to front-end problems, blockchain technology will better solve back-end problems. Among them, the application of blockchain technology in the cross-border payment field will be the most representative and will become a new trend in financial settlement.
