David Marcus, Calibra's CEO and former Facebook blockchain leader, said in an interview that US lawmakers have been putting pressure on Libra at the current stage, which is strange. This is currently a white paper and has not entered any operations. Marcu said that we need to prove that we are trustworthy. People don't need to trust Facebook to use Libra and join the platform, because many embeds and networks with interoperability will be built on this platform. Marcu also pointed out that lack of innovation is one of the reasons for creating Libra, we need a better payment system.
