There aren’t enough public details yet but I think the “blockchain” part is really just between all of the partners, not between the users. So when user A in the US sends to user B in Pakistan, the activity is really only between the two parties which converted the local currencies from the end users. That wouldn’t be particular different from user A sending a Western Union payment to user B in Pakistan. Conceivably Facebook has all of this user history and is able to make a guess if someone is a real person. Probably they know a lot more than a bank would know. That could take care of some aspects of the KYC issues too. Using the word cryptocurrency is fairly misleading, because as far as I can tell, it isn’t really one. Blockchain, maybe, but I don’t even know what that word means.
