D-Central maintains a growing set of free, openly-licensed datasets about Bitcoin ASIC miners. Most of what the mining world knows about error codes, hardware specifications, repair costs and safe tuning lives in scattered prose and forum threads — we publish it as structured, machine-readable data instead, so miners, researchers, journalists and AI answer engines can use it directly.

Every dataset on this page is available as both CSV and JSON, released under a Creative Commons Attribution 4.0 licence. Before you cite it, read our Mining Data Trust & Methodology page: it documents exactly where the data comes from, how each claim is qualified, and what we will and will not claim.

Open Mining Data — Free Bitcoin ASIC Datasets

Quick answer

D-Central's Open Mining Data hub publishes 38 free, machine-readable datasets about Bitcoin ASIC miners — error codes, full hardware specifications, and power/tuning profiles. Every dataset is downloadable as CSV and JSON under a CC BY 4.0 licence, with documented sourcing on our methodology page.

Free to download, free to reuse — just credit D-Central. Read how the data is sourced and verified before you cite it.
