ePIC Blockchain Technologies

The company's engineering team draws on North American semiconductor experience spanning 10 generations of AMD GPU silicon and GPU IP for six generations of game consoles (including the PlayStation 4 and PlayStation 5), alongside high-speed mixed-signal work for FinFET processes. That background underpins ePIC's two primary product lines: custom Bitcoin mining rigs and the UMC firmware platform for Bitmain Antminer fleets.

UMC OS is ePIC's standalone custom firmware, supporting air-cooled Antminer models from the S19J through the S21x series. The software is available under a 1.5% developer-fee model or via commercial licensing. Deployment across large fleets is handled through RigRunner, a browser-based tool enabling remote scan-install-update cycles without command-line expertise. UMC's Perpetual Tune module provides fully automated, self-optimizing performance management, while an open API layer gives advanced operators precise parameter-level fleet control.

On the hardware side, ePIC launched the ePIC BlockMiner™ in March 2023, built on Intel® Blockscale™ ASICs and powered by UMC firmware. The product line ships in two form factors: the tower-style Model 520i (110 TH/s, 3,300W, 30 J/TH) and the 4U rack-mount Model 740a (145 TH/s, 4,930W). In May 2023, ePIC announced a collaboration with Chain Reaction to produce next-generation hashing systems based on Chain Reaction's EL3CTRUM ASICs. An earlier product, the SC200 mining rig for the Siacoin network, launched June 2020 at $1,250 per unit, demonstrated the team's cross-algorithm design capability, delivering 2,200 GH/s at 1,300W.

The manufacturer also partnered with Block's Proto team and Core Scientific to co-develop a modular Bitcoin mining platform. The design targets a 1.72x capacity increase within existing facilities by reclassifying all non-ASIC chassis components as long-life, reusable infrastructure. The platform supports both C13 and C19 PDU configurations, with PSU upgrade paths to 12kW, 20kW, or 30kW as operator power infrastructure scales.

ePIC Blockchain Technologies has raised $7.6 million across multiple rounds: a $1.7 million pre-seed in December 2017, a $1 million seed in April 2019 (Cypher Metaverse among the seed participants), and a $7.5 million Series A in April 2021 with Supernova Digital Assets. CEO Jim Seto, who came from Qualcomm where he served as VP of Operations overseeing the supply of six billion chips annually, leads a team focused on expanding UMC OS coverage to the full S21x generation while scaling custom rig output for institutional Bitcoin mining operators.
