nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn #asknostr I’ve implemented nostr auth in an app I’m building. If I want to store some user preferences on a private server that’s not a nostr event, is it a good pattern to use the users keys to sign and verify them on the client before posting their preference to my server/db?
