Trying to come up with a decentralized payment split tracking app. The entire idea is that there is no centralized server, everyone can just connect with each other and just add splits easily. I thought of nostr as the backend for storing but that's not super feasible in my opinion? Or is it? The next option is P2P transaction but then if all devices lose the data, everything is lost, which is OKAY? I can't decide on what to go with
