Today, Chen Weixing said on Weibo that Libra is a blockchain system with Facebook-invited associations for accounting. They are almost all common interests, often meeting together, and rejecting specific groups (such as Chinese) as nodes; Bitcoin is a blockchain system for accounting through a competitive competitive algorithm. They are competitors and even rivals, defending each other, reporting, attacking, and attacking each other. There is no possibility of collusion. This is why the Bitcoin blockchain network is far more reliable than the Libra blockchain network.
