rvz | on: Payments Canada announces launch of Canada's Real-Time Rail (RTR) payment system
So FedNow for Canada, meaning you can't use this outside of Canada at all.

Crypto blockchains like Solana, XRP, Stellar and Tempo on the other hand can be used anywhere worldwide, 24/7 and sends stablecoins like USDC in seconds with extremely low fees.

Crypto blockchains are useless for these kinds of transactions because in the real world people make mistakes, get scammed, or myriad other things that requires a transaction to be reversed.

No different to a bank transfer. You understand that they cannot be reversed either?

There's nothing technically requiring a bank transfer not to be reversed. I can appeal to my bank, legally, and to the receiving bank.

This happens all the time.

Pix has a reversal mechanism precisely for errors, fraud, etc

As understand it, these mechanisms do not help in the case of fraud or disputes. No way to reverse transactions.

You can't reverse a bank transfer either and payment services such as Zelle are a favorite for scammers and also cannot be reversed either.

So you have not made a point here.
