It is not a DTC, despite the DB world using ATM's wrongly as an example for decades, follow their model for actually moving money and you would be sent to jail.

"Accountants don't use erasers"

The ledger is the source of truth in accounting, if you use event streams as the source of truth you can gain the same advantages and disadvantages.

An event being past tense ONLY is a very critical part.

but over-reliance on ACID DBMSs and the false claim that ATMs use DTC really does hamper the ability to teach these concepts.
