To be clear, the cryptographic underpinnings of blockchain seem solid, it's just that both implementations and actual usage are by fallible humans. And because everything is irreversible, even if you manage to guard against hackers, you still can straight up incinerate money by (say) mistyping a receiving account number (wallet).
See no mention of Bitcoin or Ether in that page, only centralized shitcoins such as Solana and a few buggy smart contracts. Also, if the system is to be operated by only the banks then transactions _can_ be reversed when needed due to security issues. I don't have a strong opinion whether this is a good option or not, just saying that it's not as absurd as it may seen.
Seriously? You would trust billions of dollars to this?
