Saw this on nostr by Melvin Carvalho:
No one wants to admit it, but: everything you can do on Nostr, you can do on a regular web server, aside from real-time updates via relays, which could be added pretty quickly. The value in Nostr is more about spreading Bitcoin's taproot as an identity system, making Bitcoin more social, and demonstrating a design pattern for how taproot identity and payments could work across the web. We don’t need relays for this—the existing web is fine. What’s needed is the imagination to upgrade it into a self-sovereign, payments-ready system that belongs to everyone. And this already provably scales to 5+ billion people.
As I (poorly) understand, nostr somehow uses the same tech as taproot. I think it has to do with the nostr keys being the same or in the same format or cryptography. I really don't know. Someone, might have been Melvin, explained to me once that nostr can somehow intrinsically hold bitcoin ordinals (which exist because of taproot).
We need an explainer for dummies on this.
