EthBoulder is a three day Ethereum unconference and hackathon taking place February 13–15, 2026 in Boulder, Colorado. A decentralized and community-governed event, EthBoulder brings together builders, researchers, artists, and curious minds to explore open source coordination, distributed systems, and AI integration through participant-driven sessions. Accelerating Human-Scale Coordination EthBoulder focuses on practicing Ethereum as a living system. Sessions center on collaborative dialogue, collective problem solving, and building in the open – creating space to test ideas, ship solutions, and experiment with how coordination on Ethereum works at human scale. Designed for Participation Shared lines of inquiry give participants a common orientation. Some emphasize deep technical building and vibe coding with AI – others center coordination, creative practice, or applied research. Participants are free to move between forms of engagement as interest and energy converge. This design anchors continuity across the event without prescribing outcomes, allowing ideas and collaborations to meaningfully compound over time. Where People Meet Protocol In Boulder, the horizon feels like a frontier. The mountains are more than scenery – they're a reminder of patience, effort, and durability. Join us Feb 13-15, 2026 to connect code with culture, creativity, and the human-scale coordination required to build a better future on Ethereum.
