Subnostr

It's nice to restart minibits wallet after receiving zaps on nostr for a while and seeing a bunch of nuts appear in your wallet one by one.

Note on privacy: Lightning addresses are static identifiers which means that it's obvious to the server that you receive a payment. The sender has very good privacy. The good thing about ecash is that the moment after you receive a payment (that was traceable because it came from your LN address) your ecash becomes untraceable again because that's just how crazy powerful blind signatures are.

Hi Calle, which app for iOs do you recommend for cashu?

Okay, here's an idea: let's build a layer on top of lightning addresses that lets you define a public key associated with the address.

Something something cryptography, the mint receives the payment and locks it to a key that only the receiver and sender knows and boom!

The idea is the wallet chooses to generate a unique address [id]@mint.com and the mint cannot associate the id with the receiver but because the id is based on a public key, the receiver can.

I'm not cryptography guy, but it seems like a feasible idea based on all the other things I've seen.

This is literally what is being built right now.
