HASHRATE UP #045 – Optimizing Bitcoin Miners: Control Boards, Firmware & Cooling w/ Jim Seto
In this episode, Jesse is joined by Jim Seto, CEO of Epic Blockchain Technologies — a hardware-first company focused on building smarter, more modular Bitcoin mining systems.
Jim explains how Epic develops custom control boards, firmware, and full-system ASIC solutions for miners operating in both large-scale and remote environments. The conversation dives into:
- Why control boards are the “nervous system” of a mining rig
- Firmware upgrades that improve uptime and efficiency
- Thermodynamic limits and the future of air vs. hydro cooling
- Modular hardware and second-life strategies for aging ASICs
- Working with Bitmain, Intel Blockscale, Gridless, and more
- Mining infrastructure in Africa, LATAM, and the Middle East
- Raising capital, scaling lean teams, and staying customer-driven
“Our clients want control, resilience, and flexibility. That’s what we build for.”
