Hashrate Verification
Pool-reported and metered draw compared against manufacturer sheets for units above 0.05 PH/s.

Know Your Miner Family Before You Plug In
We review Antminer, Whatsminer, AvalonMiner, and other ASIC families operators already recognize — comparing real hashrate, power draw, and cooling demands for Korean grid conditions.
What We Review On-Site
Thermal Behavior
Ambient swing tests and fan-curve notes for Korean summer humidity profiles.
Pool & Firmware Fit
Which stratum endpoints and firmware branches behave predictably on your VLAN layout.
Flagship Consultation
Miner Family Assessment
A structured visit to your facility or our Wonju review bench. We walk through one or two miner families you are weighing — power cabling, breaker sizing, noise limits, and expected daily coin output at your tariff.
Deliverable: a written comparison with hashrate confidence bands, not a sales brochure from any manufacturer.
Full Assessment DetailsOperator Voices
We were split between S19 XP and M50S for a 0.12 PH/s expansion. The report spelled out breaker loads we had underestimated — saved us a rewiring pass before machines arrived.

More Operator StoriesThe Whatsminer section was thorough. I still think their noise figures are optimistic for our tin roof shed, but the humidity notes were spot-on for July.
