Yeah I've been thinking about something like this for a couple years now. My first attempt was building something in top of ipfs, but that was kind of a nightmare.

At one point I scraped all of the routes from mountain project, I think I have them somewhere so it's a good "seed" to start something.

Creating a nostr client for climbing seems like the next logical step. Zapping or sending ecash to route developers would be 🔥.
