DCENT_OS Beta: What to Expect Next

Welcome to the DCENT_OS public beta. This page is what to expect, in plain terms — read it before you flash anything. Everything here is honest about a project that is still experimental: public beta since 9 July 2026, downloadable images for two control boards, GPL-3.0. Beta means beta.

What this is, in one line

DCENT_OS is open-source (GPL-3.0) Antminer firmware, in public beta since 9 July 2026. Downloadable images exist for two boards — the Antminer S9 (Zynq/XIL control board) and the Antminer S19j Pro (Zynq/XIL) — at /downloads/dcent-os/beta-20260709/. Everything else reads “Support incoming.” Nothing here is a finished product.

What “public beta” actually means

Public beta means anyone can download an image, flash it on supported hardware, and tell us what breaks. It does not mean the firmware is finished. We are deliberately slow here, the same way we are deliberately slow building hardware to order: we would rather ship an image that is safe to flash than ship one fast and brick someone’s miner. Concretely, public beta means:

• Experimental, not production. DCENT_OS can brick a miner, cause downtime, and flashing third-party firmware can void your manufacturer warranty. Treat every build as software you might have to recover from — keep SD and serial recovery ready, and do not flash production miners.
• Two boards today. The Antminer S9 (Zynq/XIL board) and Antminer S19j Pro (Zynq/XIL board) have public images. Other S19-family boards, the S9’s BB/CV/AML boards, and the S17 and S21 families are in active development — one validated control board at a time, no dates promised.
• Signed, verifiable downloads. Packages are Ed25519-signed and ship with SHA256SUMS.txt — verify before you flash. The dated beta status page is the source of truth for what is flashable; if a slot reads “Support incoming,” that is the honest state.
• Open source by design. The firmware is GPL-3.0 with a 0% mandatory dev-fee target and an optional contribution setting for people who choose to fund the work. Read the code at github.com/DCentralTech/DCENT_OS.

How to run the beta, in order

We do not send newsletters and we do not broadcast. The beta is self-serve now — here is the honest sequence:

1. Get ready first. Work through the hardware-readiness and recovery checklist and read the rollback & UART recovery guide. Recovery first, always.
2. Download and verify. Get your board’s image from the beta download directory and check it against SHA256SUMS.txt. Packages are Ed25519-signed.
3. Install. Flash the S9 SD image with balenaEtcher (see the S9 SD-card install guide), or install a .tar package with DCENT_Toolbox: dcent install <MINER_IP> -f <file>.tar — the DCENT_OS web updater works too.
4. Report what breaks. The live channels are the beta status page (dated, updated first if anything slips), the GitHub repository (issues, commits and releases), and the Discord community for build notes and tester chat.

Where things stand, stated honestly: the public beta opened 9 July 2026 with images for the S9 XIL and S19j Pro XIL boards. The A/B NAND install path is offline-proven, but our witnessed live-hardware boot-and-mine capstone is still in progress — which is exactly why the recovery checklist comes first. Additional boards ship when they are safe, not on a calendar, and the status page says so before anywhere else does.

Get ready before you flash

The single best thing you can do before flashing is to make sure the miner you intend to flash is recoverable. The readiness work is the same for any custom firmware. Start here:

• Hardware-readiness & recovery checklist — pick a miner you can afford to take offline (never a production miner), prepare a recovery SD card, confirm UART access, and back up your current config before you change anything.
• SD card firmware flashing & recovery guide and recovering a bricked ASIC — the generic recovery skills that apply no matter whose firmware you run.
• Repair bench — if a flash goes wrong and you cannot recover it yourself, this is the same bench that has serviced thousands of miners since 2016. Recovery support is a separate service, not a warranty on the firmware.

Want to run it on hardware we hand-build?

The Bitaxe side of DCENT has a separate, easier path. DCENT_axe is our open-source Bitaxe firmware, and it flashes straight from your browser with the web flasher — no SD card, no UART. If you are new to open mining hardware and want a low-stakes place to start, The Bitaxe is the entry point. That is a different tool from the Antminer SD card images this waitlist is about, but it is the same philosophy: open, recoverable, yours.

Shoulders we stand on

DCENT_OS stands on real, prior work: the CGMiner / BMMiner lineage, Braiins’ open-source firmware and Stratum V2 protocol work, Luxor’s tooling for the mining community, and the open-ASIC community — skot9000 and the ESP-Miner / AxeOS project — around the Bitaxe. DCENT_OS is one more layer of a stack other people started; the goal is simply one more layer decentralized.

FAQ

Where do I download DCENT_OS?

From the beta download directory: /downloads/dcent-os/beta-20260709/. Verify your file against SHA256SUMS.txt before flashing. Packages are Ed25519-signed.

Does the beta cost anything? Is this a pre-order?

No and no. The downloads are free, the source is GPL-3.0 open source with a 0% mandatory dev-fee target, and there is nothing to purchase to run the beta.

When will my miner get an image?

The S9 (Zynq/XIL board) and S19j Pro (Zynq/XIL board) have images today. Every other model and board is “support incoming” — we ship an image when it is safe to flash, not before, and we do not promise dates. The beta status page is updated first when anything changes.

Which miner should I use?

An Antminer S9 (Zynq/XIL board) or S19j Pro (Zynq/XIL board) you can afford to take offline — never a production miner. Work through the readiness and recovery checklist so the miner is recoverable before you flash.

Can DCENT_OS brick my miner?

Yes — it is experimental beta firmware. Flashing custom firmware can brick a miner, cause downtime, and void the manufacturer warranty. Only flash a miner you are prepared to recover, and read the full brick-risk warning first.
