A small, hands-on summit on heating buildings with open-source Bitcoin miners.
Hashrate Heatpunks' third summit brings mining developers, HVAC professionals and policy experts to Denver for two days of workshops on the open-source Bitcoin mining stack.
Heatpunk Summit is run by Hashrate Heatpunks, a community project of the 256 Foundation, a US non-profit. It is about using Bitcoin mining hardware as a heat source, and building that hardware on an open-source stack. The 2027 summit, its third, takes place at The Space in Denver's RiNo Art District under the theme Accelerate.
It is kept small and hands-on, with attendance curated through a waitlist; the 2026 summit had more than 150 attendees. Sessions cover the state of the open-source mining stack, workshops on firmware, reference designs and pool setup, live hardware demos, and a review of case studies and policy work on residential and commercial adoption.
