According to the interface news, Patdy Cosgrave, founder of Web Summit, Europe's largest technology summit, recently said that the application of blockchain technology is rare. Maybe it's a revolutionary technology, but it takes a long time to develop. As far as I am concerned, I am more optimistic about another technology FHE (fully homomorphic encryption), I think it will have more development prospects than the blockchain. I think that Libra's cryptocurrency features are relatively small, but it is more like payment tools like Alipay and Tenpay. Running in more than 200 countries with more than 150 currencies, Libra provides Facebook with a global e-money tool to solve transactions and payments. Facebook is using a more open and cooperative attitude to solve the global currency problem, although many people are worried that the younger generation will use Facebook less and less, which means that Libra relies on a reduced user base, but they ignore Facebook. A huge user base of two major softwares for Instagram and Whatsapp.
