Until cryptocurrencies can deal with 51% attacks they are a waste of time in my mind. The technology is interesting, and that's about it.

51% attack applies to mining. Libra will not be mined. They have 33% attack on voting... but if 1/3 of the founding companies disagree about some transfer, they've got bigger issues than just that attack.

If there is no mining, how does proof of work occur to create coins? I only have an understanding of how blockchain works, but proof of work seems like a necessary ingredient in any cryptocurrency system.

Another comment in this thread says there is no proof of work. And that it isn’t actually a cryptocurrency.
