It's wild. I just proved I can build #nostr 'wallet' where I can store the encrypted tokens in a Germany relay and make the lightning payment out of a Singapore mint. All using a #nsec that never leaves my machine. https://primal.net/e/note15l02rf4r474ck04mlrxxfagyl0z6t04ltsugf9dtph4xxhzfnd4sqpk74n

I’ve proven to myself that a #nostr wallet can exist across time and space, independently of any one app, server or custodian. The only thing which controls the ‘wallet’ is the generation and control of an #nsec which is free to exist within or flee any jurisdiction.

In my mind, this lays to rest the notion that a wallet needs to be an app, service, or anything that can be captured commercially or by the state. https://primal.net/e/note13nwsh852x9tfex2jade6vwymhhct8zussxr4zwy7uag24hjc9stq0xsxaf

I am thinking about coining the term “nsac” to refer to a wallet-like thing that can exist on #nostr holding your valuable things, such as ecash tokens. I have already implemented a prototype #cashu ecash wallet which looks to be promising.

So you would have: #npub - your identity #nsec - your private key #nsac - your valuables

Your #nsac could be the same as your #nsec but better case is to generate as many #nsacs as required.

Happy to hear feedback!

For reference, what a ‘sac’ is in the biological sense:

A sac is a biological term referring to a pouch or cavity in an organism that is typically enclosed and may contain fluid, air, or other substances. Sacs can serve various functions depending on their location and role in the body, such as protecting a developing embryo, facilitating the exchange of gases in the lungs, or reducing friction between moving parts in joints
