I get you with needing a ledger, which most banks use.
I'm assuming Revolut do as well, but this engineer wasn't aware. Or perhaps it was a different question they thought they were asking, or maybe a misunderstanding.
But the two ATMs problem would be solved by securing a lock on the database before proceeding with the transaction?
