1. retreats
Vinteum, a nonprofit supporting open-source Bitcoin development, has been running focused in-person developer retreats to accelerate work on critical infrastructure projects. According to Vinteum, the retreats brought together contributors from DIY hardware wallet projects Krux, SeedSigner, and Specter-DIY to address shared dependencies and fragile maintainership around Embit, a core Bitcoin library for embedded systems. A separate gathering assembled the Floresta team with Utreexo researchers Tadge Dryja and Calvin Kim, producing a decision to incorporate Ruben Somsen's SwiftSync protocol for dramatically faster initial block download on lightweight nodes. Additional retreats covered Stratum V2 mining infrastructure and Bitcoin Core fuzzing in partnership with Brink. As one participant described, meeting in person made it possible to "build shared dreams, not just shared code." The format compresses months of asynchronous discussion into days of side-by-side work, targeting the organizational bottlenecks that slow under-resourced teams building at the base layer.

Bitcoin's global hashrate has shed roughly 100 exahash per second since late February, and analysts are pointing to Iran as a likely contributor to the decline. Reporting in Blockspace, analysts note the drop began around the same time U.S. military strikes targeted an Iranian nuclear facility, prompting speculation that Iranian miners, who have historically operated a substantial share of off-grid and subsidized-power mining, went offline. "I don't want to overstate it, but if you're looking at macro events, that's one of the only things that lines up," one analyst told Blockspace. Iran has long been suspected of using bitcoin mining as a mechanism to convert sanctioned energy into hard currency, with estimates placing the country's share of global hashrate in the high single digits. A 100 EH/s drop represents roughly a 10 percent reduction from recent peaks above 1 zettahash per second, and while network difficulty will self-correct within the current epoch, the episode highlights how geopolitical shocks can translate rapidly into measurable changes in mining geography and network performance.

Writing in his newsletter, Frank Corva highlights how Bitcoin and freedom technology functioned as emergency infrastructure in Jamaica after a hurricane knocked out banking and communications systems last November. According to Corva, residents used the Flash bitcoin app to move funds and the peer-to-peer messaging tool Bitchat to coordinate aid distribution when traditional systems went dark. The effort was powered by roughly $15,000 in bitcoin donated by the global Bitcoin community. Flash founder Dread, who led the ground response, is now working to build a preparedness framework using Bitcoin, Nostr, and Bitchat so Jamaica is better equipped for the next storm. Corva frames these tools under a new label his collaborators have coined: "emergency tech." The piece also recounts Corva's own experience recovering from a compromised Nostr private key, one of 18,000 exposed by a bot, noting that "community truly is the ultimate hedge" after Nostr users quickly helped him rebuild his presence and migrate to a new key pair.

Nature's annual technology outlook identifies small modular reactors and fusion power as critical infrastructure for meeting surging AI-driven electricity demand, projecting that global data center energy consumption could rise 15% annually through 2030. Writing in Nature, Michael Eisenstein profiles a wave of next-generation nuclear projects, with at least 100 SMR developments now under consideration or active worldwide, including facilities in Russia, China, and Canada's Darlington plant scheduled for 2029. "Even if the AI boom goes bust, there remains an urgent need to bolster energy grids with climate-friendly power sources," says Jonas Kristiansen Nøland, an energy systems researcher at the Norwegian University of Science and Technology. Companies like TerraPower are pursuing molten-salt reactor designs that reduce nuclear waste and store thermal energy, while more than 50 fusion startups are now active globally. The piece frames nuclear not as a speculative bet but as the pragmatic supply-side response to a structural electricity deficit that AI workloads, and by extension bitcoin mining and high-performance computing, are accelerating in real time.
