I take your point that you wouldn't want to open source everything, especially not the few critically secure bits of your infrastructure.
That said, money transfers take a couple of days because most interbank clearing houses were modelled after paper-based batch processes where people shuffle through paper a few times a day.
There are several real-time payment schemes in the world. Retail customers in the UK mostly use Faster Payments (FPS) for interbank transfers and they clear within a few seconds.
- MagicNarwhal 11y agoSecurity through obscurity hasn't been a powerful or useful paradigm for at least a decade now. The only thing that it provides now is more time for malicious users to exploit security holes before anyone notices.
- ketralnis 11y agoI don't agree. Nobody is claiming that it should be the only layer, but as one layer of many a little bit of obscurity goes a long way. For instance, reddit provides it's public source code but has all of its anti fraud stuff wrapped into a separate repo that is not public. This provides a lot of flexibility that wouldn't be available if it were all public. And sure, some of it is of temporary value ("we are catching this cheating teqnique specifically, until they realise that it's not working anymore") but the fraud arms race is much easier for the atackee if it is slowed down a bit by such temporary measures
