Signal adds a payments feature with a privacy-focused cryptocurrency

The UK already has faster payments in all major banks. I can send and receive money instantly from app or Web. Will yours be as fast as that?

The UK has a problem with authorised push payment fraud. Banks can recover funds which have been sent as a result of phishing / fraud. How can I reverse a payment on your platform if it was fraudulent?

The UK also has receiver verification. If I try to send to an account and it doesn't match the name I'm sending to, my bank will warn me. How do you stop impersonation?

There's no cost to sending payments on most mainstream banks. How much do you charge?

Most banks let the user block receiving payments from specific accounts. How do you stop harassers sending unwanted money?

Thanks!

First time I read about that, how does this work in practice? A person regularly sends you small amounts such that all you see is their name whenever you log into your bank account?
