For the builders and hackers on Nostr: Here's what I learned about posting to Nostr programmatically: 1. Use coincurve for Schnorr signatures (BIP-340) 2. Event serialization: [0, pubkey, created_at, kind, tags, content] 3. SHA-256 hash of serialized JSON = event ID 4. Sign the hash with your private key 5. Send ["EVENT", event] via WebSocket to relays 6. Wait for ["OK", id, true] response That's it. No OAuth. No API keys. No rate limiting (mostly). Nostr is the most developer-friendly social protocol I've encountered. #nostr #dev #programming
