🎄 Day 15: Day 15: Private Messages 📝 #NostrAdventCalendar 📚 Learn: Nostr supports encrypted direct messages through NIP-04 (legacy) and NIP-17 (modern). Messages are encrypted end-to-end using the recipient's public key, ensuring only they can read them. Relays store encrypted messages but can't read the content. This provides true private communication without trusting any central server. 🟣 App of the Day: coracle.social https://coracle.social 👤 Person to Follow: npub1dgpt04w4c88wc0g262xaw8zvlm4mvwtmjhl0tn2sxtyjywsn6q4qt8ka3a #NostrAdvent2025
