The room was packed. Everyone was there for the Nostr talk, to hear from people who truly know what they're talking about: @UNCLE ROCKSTAR, @Derek Ross, and many others. But I was up first. The schedule was already running late. So I walked onto the stage in the biggest Bitcoin conference in the world and did something nobody else had dared to do yet: I asked everyone to use Nostr. Live. "Zap me," I said. "Your zap, your Nostr profile, and your message will appear live on the screen next to me." Nostr can be a little shaky. This demo had every chance to fail. And the best part? It did. My @Minibits wallet never received the payments. No zap came through. There I was, on stage, in front of a packed room at the biggest conference in the world, telling people to use Nostr... and it didn't work. Honestly, it couldn't have been a better demonstration of how much work we still have to do. Luckily, the room was full of Nostr believers. They didn't laugh at the failure. They understood exactly why it mattered.

I just beat the TEAM SOVEREIGN challenge on @Chain Duel and got 6,900 sats ⚡ Can you beat it? Sign in with Nostr → pick a challenge → beat the bot → collect sats.

PROBLEM Human rights defenders, journalists, NGOs, and activists in authoritarian environments cannot reliably receive donations. Banks freeze accounts, PayPal and GoFundMe remove campaigns, and donors fear retaliation. Bitcoin’s Lightning Network solves settlement—but most tools still require merchant infrastructure, custodians, or platforms that can be pressured to cut access. SOLUTION @PUBPAY.me combines Nostr (permissionless identity + public posts) with Lightning zaps (instant, verifiable payments). A defender publishes a “paynote”—a Nostr note with payment rules—and anyone worldwide can donate via Lightning. Payments are recorded as public zap receipts on relays: transparent, verifiable, and impossible for a single company to erase. Donors can contribute anonymously. No signup wall is required to pay.

After nearly 4 years of building @Chain Duel , we finally launched the online version. The first 6 days taught us a lot, including one growth channel we weren't expecting. Here's a short launch report with the numbers, surprises, and lessons learned 👇 View article →

Some users (mostly french keyboards) reported the keys weren't responding correctly so now you can choose which keys you want to use. image
