summary
Visa frames itself as a centralized, high-performance layer two on top of fiat rails and cites $13 trillion card volume versus $120 trillion B2B and $18 trillion cash to argue networks need open entry points. Proposes open-sourcing issuer/acquirer stacks (ISO 8583 already open) so devs can run an issuer on my laptop, test BINs and auth logic locally, build developer cards that interrupt the auth stream, and speed features like real-time push notifications.
