Open Data for Journalists — Bitcoin Mining Datasets, CC BY 4.0 | D-Central

What this kit contains

D-Central Technologies has operated as a Bitcoin mining infrastructure company since 2016, with a hardware repair and refurbishment facility in Montreal, Quebec. The datasets below are compiled from field repair records, manufacturer specifications cross-referenced against the Bitcoin Mining Hack Bible, provincial utility tariff schedules, and D-Central’s secondary-market trading activity. Each dataset is published under the Creative Commons Attribution 4.0 International licence (CC BY 4.0).

This page covers five core datasets. The broader open data hub at /data/ indexes additional datasets not listed here — including ASIC chip specifications, error-code reference data, Bitaxe benchmark measurements, and the Bitcoin Mining Facts Canon. Every dataset listed below has been independently verified against primary sources. Electricity rates, firmware versions, and hardware prices change; hedge time-sensitive figures and check the last_verified date in each dataset before publishing.

Background briefings and expert comment

D-Central has operated a Bitcoin mining hardware repair and refurbishment facility in Montreal, Quebec since 2016. If you are reporting on any of the following topics, we can provide technical background, dataset context, or on-record comment:

• Bitcoin mining economics: hardware costs, energy costs, profitability, hashrate growth
• ASIC hardware: efficiency trends across Antminer generations, failure modes, repair costs
• ASIC firmware: open-source firmware ecosystem, protocol support, power optimization
• Canadian energy for compute: provincial electricity rates, Quebec hydro advantage, Hashcenter siting
• Sovereign AI / on-premise AI infrastructure: local LLM hardware, digital sovereignty, Canadian data residency
• Canadian digital sovereignty: cloud dependency, Quebec Law 25, CLOUD Act exposure

Scope of comment: Technical and operational. We do not provide financial advice, Bitcoin price predictions, or forward-looking investment guidance.

Contact us at support@d-central.tech with “Media inquiry” in the subject line, or use the contact form at d-central.tech/ai-sovereignty-consulting/. We aim to respond to media inquiries within one business day. Company boilerplate, verifiable key facts, and logo assets are available on the D-Central press page.

Frequently asked questions

Can I use these datasets in a published article, academic paper, or government report?

Yes. All datasets are licensed under CC BY 4.0, which permits use, redistribution, and adaptation — including in published journalism, academic research, industry analysis, government reports, and AI training datasets — as long as you include attribution to D-Central Technologies with a link to the source URL. No advance permission is required. See the “How to cite” section above for suggested attribution formats.

How current is the data, and how often is it updated?

Each dataset carries a last_verified date. The electricity rates dataset reflects utility tariff schedules as of June 2026; rates change when regulators approve increases, so check the last_verified date and verify at the source URL in each row before publishing time-sensitive figures. The power profiles database is updated when new models or operating modes are verified against primary sources. The reliability index is updated as repair data accumulates. The firmware matrix is updated when firmware versions change materially. The used-ASIC price index reflects weekly signals.

Are these datasets available via API for live queries or embedding?

Yes. All five datasets have live REST API endpoints at https://d-central.tech/wp-json/dc/v1/ (CORS open, no authentication). Endpoints support filters — for example, /wp-json/dc/v1/electricity-rates?ideal_mining=true returns only jurisdictions flagged as suitable for Bitcoin mining, and /wp-json/dc/v1/firmware-features?firmware=braiins returns only BraiinsOS+ rows from the firmware matrix. The REST API is the live source of truth; the static CSV/JSON files are versioned snapshots.

What is the geographic scope — is this only relevant to Canadian operations?

The electricity rates dataset is Canada-specific (13 jurisdictions). The ASIC power profiles, reliability index, and firmware matrix cover hardware and firmware deployed globally — Antminer hardware is used worldwide, and the firmware ecosystem is international. The used-ASIC price index reflects the North American secondary market. None of the datasets are restricted to Canadian use cases; the Canadian energy and sovereignty angle is one of multiple valid applications.

What is DCENT_OS in the firmware matrix, and is it publicly available?

Can I contact D-Central for comment on a story about Bitcoin mining energy use?

Yes. Use the contact form at d-central.tech/ai-sovereignty-consulting/ or email support@d-central.tech with “Media inquiry” in the subject. When reporting on energy consumption, we recommend specifying which model and operating mode from the power profiles dataset you are citing, so we can provide the most relevant context. We recommend noting in any published story that power figures are rated/nominal and real-world consumption varies with operating conditions.
