Nostr Web Client

It could be. As long as the remaining processes run as a mobile app, not as deamon. The app show start, sync and be removed from memory every 15 mins or so. Than a separate Android Service simply listens to 0-conf transactions for simple notifications. The important part is a complete redesign of the interface to do the simplest thing Bitcoin does and nothing else.

I like it. We need more experimentation with bitcoin nodes. The biggest problem is recreating bitcoin consensus logic. You basically can't guarantee it will stay in consensus, so that's a bit of an issue...

You could probably get very far with blocks only mode. It has a mempool so you can simply drop every transaction you aren't interested in and keep the ones you are watching for via sendrawtransaction.

Not sure how you would learn about the transaction if your node isn't listening when it floods across the network. Perhaps a mempool nostr relay that just replays transactions as nostr events.

Or maybe just listening and immediately discarding everything. Pokey keeps listening on the background. It could work as long as the service doesn't really big Android too much.
