When I need to send my sister who has a bank account with the same bank that I have an account with, I can zelle her within minutes. I've done this once every month for the last year. In the beginning, it told me that it takes "a few days" to send amounts over USD 500 (my amount is USD 2,000). However, recently I have noticed that it says "a few minutes" for my request. There is no cost associated with it.
Assuming there is zero fraud protection, zero liability, zero anything for the transaction, is it possible to send and receive payments for free, at no cost, using any block chain technology? If yes, how can we get there? If not, why not?
