Last updated: 12 June 2026. This is the single honest source of truth for where DCENT_OS actually is. Wherever the site says “summer 2026,” this page is where you check what that means today. Dates here are estimates, not guarantees — we ship an image when it is safe for your hardware, not before. If a timeline slips, this page says so first.

Status in one line

DCENT_OS is in closed beta on the Antminer S9 today. There are no public image downloads yet. Public beta is planned to open with the first downloadable Antminer S9 SD card image; S19 and S21 support is in active development and follows after. Everything is experimental and can brick hardware — flash only a miner you can recover.

What “public beta” means (staged)

We are not flipping a single switch. Public beta opens in stages so nobody bricks a miner on day one:

1. Stage 1 — Antminer S9 SD card image. The first public download: a flashable SD card image for the S9 family (XIL / BB / CV / AML control boards, validated board by board). This is the milestone the “summer 2026” estimate refers to.
2. Stage 2 — S19 family. S19 / S19 Pro / S19j Pro images follow once bench validation and a proven recovery path exist for each control board.
3. Stage 3 — S21 family. S21 support is in development and ships last.

If your exact miner and control board still reads “Support incoming” in the beta download area, there is no public image for it yet. Do not flash it.

What works in closed beta today (Antminer S9)

• Mode-first control: Basic Heat (temperature and noise first), Standard Mine (familiar miner controls), and Advanced Hack (low-level controls for users who accept beta risk).
• A mining daemon written in Rust, a memory-safe systems language.
• A 0% mandatory dev-fee target, with an optional contribution setting for people who choose to fund development.

Closed-beta testers are running these on S9 hardware now and reporting what breaks. That feedback is exactly what gates each public stage — the timeline answers to the hardware, not the calendar.

What is planned, not shipped

To keep the promise honest: the GPL-3.0 open-source release of the full firmware stack is planned after the public beta period, with public repository access currently planned for summer 2026 (an estimate). Anything described elsewhere on the site as planned — additional models, additional features — is a target, not a shipped guarantee. We treat firmware the way we treat hardware lead times: an honest estimate, never a promise of speed.

Honest risk note

DCENT_OS is experimental firmware, not a production product. Flashing custom firmware can brick your miner, cause downtime, and void the manufacturer warranty. Only flash a miner you are prepared to recover. Read the full brick-risk warning before you do anything.

How to follow along (no email broadcasts)

We collect waitlist emails and reach out once — when your slot opens. We do not send newsletters. The live channels are:

• Join the beta waitlist — leave your email and we contact you when the S9 image is ready to flash. Waitlist only — this is not a pre-order. New here? See what to expect after you join.
• Get your hardware ready — work the hardware-readiness & recovery checklist while you wait, so the miner you flash is recoverable before any image exists.
• GitHub — watch github.com/DCentralTech/DCENT_OS for commits and releases. A GitHub release is how we announce each build.
• Discord — join the community for build notes and tester chat.
• Build log — we publish a weekly closed-beta build log on the blog: what testers broke and what we fixed.

Running the Bitaxe side instead? The DCENT_axe firmware flashes straight from your browser with the web flasher — that is a separate tool from the Antminer SD card images above.

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

When is DCENT_OS public beta?

Public beta is planned to open in summer 2026 with the first downloadable Antminer S9 SD card image. That date is an estimate; we ship when an image is safe to flash, and this page is updated first if it changes.

Can I download DCENT_OS now?

No. There are no public image downloads yet — every slot in the download area reads “Support incoming.” Join the waitlist and we will reach out when the S9 image is ready.

Which miners are supported first?

The Antminer S9 family is first. S19 and S21 support is in active development and follows in later stages, one validated control board at a time.

Is DCENT_OS free and open source?

The goal is a GPL-3.0 open-source firmware stack, published after the public beta period, with a 0% mandatory dev-fee target and an optional contribution setting. It is experimental beta software today, not a finished product.
