“The current mining landscape is dominated by proprietary, closed-source players who aren’t really serving the needs of the market. That creates an opportunity for open source mining to matter again.” Bitaxe creator Skot dives into the state of modern Bitcoin mining, where a small handful of industry players control nearly every facet of mining hardware and ASIC production—in a tightly sealed, closed-source environment. While Bitcoin software developers often champion a rigorously open-source ethos in building, Skot shares why the mining industry “isn’t like that” and how closed-source mining production creates unique centralization vectors—from limiting participation by “pleb” solo miners to exacerbating geopolitical risks on an industrial scale. Thankfully, we’re starting to see a shift in demand and supply of open-source mining tools—including the recent development of “Bitaxes,” which have notably revived the solo miner community over the last year. In this episode, Skot shares the full history of the open-source mining movement, including: - How ASIC manufacturers like Bitmain and foundries like TSMC came to dominate the industry, and why competition at the silicon layer is so challenging - The geopolitics of chip manufacturing and the near-monopoly of China & Taiwan in developing ASIC technology - Why mining systems producers keep their technology so close to the vest, and who these closed-source systems most hurt in the process - How advocates at the independent and corporate levels (think: Skot and Jack Dorsey) are challenging the status quo and leading the open-source mining revolution Shout-outs in this episode to the Texas Energy and Mining Summit Bitcoin Park, and early Bitaxe supporters ZK shark and Ordinal Maxi Biz.
