For the past three years, we have been developing nostr:nprofile1qyghwumn8ghj7vf5xqhxvdm69e5k7tcpzamhxue69uhky6t5vdhkjmn9wgh8xmmrd9skctcqyzekx0aeuh3xerdwp2m49uclwhvznmy60tuuv23ajjdqsd27x2npxm586kc , an open-source educational game that teaches Bitcoin and Lightning through play.

Presented at nearly 30 Bitcoin conferences worldwide, it has educated thousands of people by turning Lightning payments into a fun, hands-on experience. The game’s design, infrastructure, and integrations have been refined through years of feedback from the Bitcoin community, resulting in a polished and reliable platform.

However, conferences only reach a limited audience. Millions of people, especially in regions with financial repression or no access to meetups, still lack opportunities to learn about Bitcoin and freedom technologies. Our goal is to bring this experience to them.

The next phase of Chain Duel will evolve it into a global online multiplayer platform built on NOSTR for identity and coordination, and on the Lightning Network for real-time, censorship-resistant microtransactions. It will combine gameplay, education, and open-source tools to make learning Bitcoin accessible to anyone with an internet connection.
