Nostr needs more fitness. Let’s call it “Iron Ledger”. The Core Idea: A Nostr native fitness accountability app where workouts are published as signed events, peers zap to validate them, and a bot npub (the “Spotter Bot”) rewards streak consistency with auto zaps. Every workout is a signed cryptographic event on a public relay. No central server can delete your streak. Your proof lives on Nostr. Your reward lives on Bitcoin. That’s the pitch. Ideas and concepts are welcomed!
