Sharing some more of my design…

Sharing some more of my design and architectural thinking for #nostr #safebox.

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!
