Post to Nostr the ability to proof investment

[dangershony]

Ideally posting to a nostr relay with a message proof of ownership of a key that belongs to the investors (use in the investment tapscript)
The benefit here is the ability for a Nostr user to show they have invested in a project on Angor

hey @dangershony i was working in this issue i have qs for this should the investment proof be publicly visible on Nostr or encrypted so only specific users can verify it?

I guess when posting it should allow to post as a public note or as a dm to a list of npubs

Hi @dangershony, before I start a few quick questions:

1. What level of proof just a public note with txid, or actual BIP 322 signature proving the investor controls the key in the Tapscript?
2. Should the note be kind 1 (visible to everyone) or kind 30078 (structured, app-specific)?
3. For the DM option is the recipient list manual npub input, or just the founder?
4. Should amount/txid be included in the public note, or just the project identifier?
5. Auto post after investment broadcasts, or a manual "Share" button?
