I wanted to share two Bitcoin and Nostr native tools that have proven extremely effective for real-world adoption at conferences and community events:
@PUBPAY.me LIVE and
@npub1kd3n...sdth.
PubPay LIVE adds a live value-for-value layer to talks using Lightning + Nostr. Each performer gets a live QR on screen, letting the audience zap sats and send comments that appear instantly. It turns passive observers into engagers and onboards people to Lightning and Nostr without friction.
Chain Duel complements this on the competitive side. It’s a multiplayer Lightning game where players scan a QR, deposit sats via LNURL, duel in real time, and the winner takes the pot. It’s one of the simplest ways to make Lightning “click” through play.
Together, they work before, during, and after talks — onboarding users, creating real economic activity, and making Bitcoin tangible rather than theoretical.
