I’ve basically built a private layer 3 with cashu, relays and mints. If one #nostr #safebox Lightning address detects that the recipient address is a #safebox, it negotiates the payment without even touching Lightning. Same with the card payment system I am building- it does not touch Lightning.
A lot of my insights came from the high bandwidth discussions being part of nostr:npub1s0veng2gvfwr62acrxhnqexq76sj6ldg3a5t935jy8e6w3shr5vsnwrmq5 and doing actual field testing.
As far as the user is concerned, they are making a payment in the currency of their choice, and need not care if it’s ecash, lightning or bitcoin. I am abstracting all that detail away.
The bottom line is that the user wants a private payment network that settles instantly - just like cash. That is what I am trying to build along with the capability of just carrying a card in your pocket (leave your phone at home) but still be able to send and receive payments.
Give me zap
