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.”
