The first diagram shows the main elements of the substrate capabilities, namely #Blossom, #Cashu, #Nostr, #Lightning, and #Bitcoin. Eventually all of this will be abstracted away from the users who only care about the safekeeping of their #Funds and #Record.

The primary coordinating protocol I am building for #safebox is called #nAuth (you can see the interaction diagram on the next image). #nAuth is built on NIP-17, NIP-44, NIP-59 and extends NIP-47 (Nostr Wallet Connect). I have extended NWC to offer and accept records between safeboxes, and to send and receive payments between safeboxes, so that they don't have to drop down #Lightning to settle payments - they are all cleared using the #Cashu mints.

In the end, my vision is very clear for #safebox (even though the engineering is hella complicated) - to give users the ability to safekeep and use their funds and records, to directly and privately transact with one another, and without necessary reliance on their app, device, or platform provider.

It will take some time - I am rooting out the single points of failure, roots of capture, and invisible gatekeepers, but I see a path to create a global, generic capability that anyone (including agents) can use without permission.

Onward!

I believe it's something like this:

'Safekeeping of my funds and records, without sacrificing ease of use."
Simply put, if I don't have my phone, but know the access key (or have the card or physical token), I can still make a payment or present a proof, privately.

The diagram below shows how it hangs all together at a high level. Under the hood, it's #nostr, #cashu, #bitcoin, #lightning, but if done right, all this protocol detail will be hidden from the user. All they need to know is that they have an easy way to pay and to prove, and with the assurance that no one provider has locked them into their service.

Onward!
