We give the code away. You keep it alive.

Why we ask

We’re Bitcoin mining hackers, not a foundation with a grant. Every firmware release, every open-hardware board, every enriched reference page is the output of real research and real technician hours — plus the failed experiments and the token burn behind the ones that shipped. The code stays free whether you contribute or not. Contributions are what let us keep shipping, keep it lock-free, and keep giving it away.

Prefer a one-time contribution?

No subscription, no account. Contribute once — in Bitcoin (on-chain or Lightning) or by card. Bitcoin is the most on-ethos way to support a sovereignty stack, so we lead with it — but card works just as well.

Frequently asked questions

Does contributing give me extra rights to the code?

No. GPL-3.0 and CERN-OHL-S already grant everyone the freedom to use, study, modify, build, and share our work — including commercially. Contributing funds ongoing development and maintenance; it does not add, remove, or unlock any rights. The code is yours to run whether you support us or not.

Is my contribution tax-deductible?

No. D-Central is a company, not a registered charity, so contributions are not charitable donations and are not tax-deductible. We call them contributions and supporter subscriptions for exactly that reason.

Do I have to be a Commercial Patron to use your work in my business?

No. Commercial use is always free under the open-source licenses. The Commercial Patron tier is voluntary, ethical patronage — a way for businesses that profit from the commons to help fund it. It is not a licence and unlocks nothing in the code.

Can I contribute in Bitcoin?

Yes — and we encourage it. One-time contributions can be made on-chain or over Lightning. Recurring supporter subscriptions are card-based today (Bitcoin doesn’t do card-style recurring cleanly yet), but you can fund a full year in Bitcoin any time.

Can I cancel a supporter subscription?

Any time, yourself, in a couple of clicks — no email, no phone call. You’ll get a receipt for every charge and clear renewal reminders. Cancelling stops future charges; it never touches your right to keep using the software.

Is any of this a subscription to unlock features?

Never. We will never gate covered code, degrade non-supporters, add DRM, or make the tools phone home. Supporter perks are recognition, community, and access to our roadmap — never a feature of the open-source software itself.

Where does the money actually go?

Development, hardware R&D, technician bench time, public knowledge infrastructure, and keeping everything lock-free — see “Where every sat goes” above. Contributors and Commercial Patrons receive a quarterly behind-the-scenes report on exactly what moved.

Who is behind this work?

D-Central Technologies — and the giants whose shoulders we stand on. Our firmware learns from BraiinsOS+, VNish, and LuxOS; our hardware descends from Skot’s Bitaxe and the OSMU community; our mesh builds on Meshtastic and LoRa. We credit them on every product page, and your support helps us keep contributing back.
