So, the current situation if you get scammed via Venmo/PayPal or other electronic payment methods is for the FBI / local law enforcement to subpoena the provider for records about the incident.
Now, imagine all that data is sitting on Federal servers by default. No subpoena required, and fraud systems would be integrated directly with investigative services at the Federal level. This integration should strike fear in the heart of anyone who currently scams via 3rd-party payment providers.
I am bothered that fraud isn't directly addressed in this page, but it's only an FAQ and it'd be silly to think the Fed wouldn't build industry standard (or better) fraud protections into a system they're building from scratch.
