Templeton, who spent a decade in semiconductors before helping Apple design the original iPhone's camera system and later leading Square's product development, expanded his scope to also lead Block's Bitcoin initiatives, rethinking how mining hardware is built. His approach: ask miners what actually hurts, not what they think they want. "The people who live and breathe this every day are the experts," Templeton explained at the recent Nashville Energy & Mining Summit. "Going in with preconceived notions about how it should be, you're not going to arrive at the best solution." The result is Proto, Block's new Bitcoin mining initiative that challenges fundamental assumptions about hardware design. Rather than viewing miners as monolithic devices, Proto reconceptualizes mining equipment as modular infrastructure where individual components, power supplies, cooling systems, and other elements, can be upgraded independently as chip technology advances. This shifts the industry paradigm from disposable hardware to sustainable, repairable systems. Templeton's methodology with Proto and Bitkey mirrors his earlier successes at Apple and Square: extensive customer interviews across diverse segments. His team consulted with large-scale operations, small miners, technicians in East Africa and West Texas, and fleet managers. Common themes emerged immediately: quality, durability, repairability, and a fundamental lack of understanding about why mining hardware was designed the way it was. "Why does it have to be shaped like a shoebox? Why do you have to throw out perfectly good components when upgrading? Why do you have to take it off the rack to repair it?" Templeton asked, applying first-principles thinking to an industry that had accepted these constraints as inevitable. Block's approach includes releasing open-source software, reference designs, and comprehensive documentation, tools Templeton views as essential to decentralizing Bitcoin mining. "The biggest way we help with decentralization is open source, talking to community, giving tools and access," he said. Rather than prescribing mining's future, Templeton emphasizes Block's role as an enabler. "If we try to decide what's going to happen, we're going to be wrong. The community will find those uses," he noted. For those interested in contributing, Templeton's advice is straightforward: identify your expertise and passion, dive in, and recognize that Bitcoin's developer community is smaller and more welcoming than most expect. As Bitcoin adoption accelerates, the infrastructure supporting it requires the same user-centered design rigor that transformed consumer electronics.
