DCENT_OS Release Evidence

Identity & status — evidence ledger dated 2026-09-01

AVAILABILITY: RELEASEDMATURITY: EXPERIMENTAL

All 13 Antminer models in the registry are publicly released on the Experimental channel. Experimental is public firmware for testing and informed, non-critical use; it is not Stable or GA and is not recommended for an irreplaceable fleet.

The verified artifact ledger currently contains files for exact Antminer S9 + Antminer S19j Pro lanes. Binary scope is separate from release status; every lane retains its own installation and recovery limits.

DCENT_OS releases are documented as immutable evidence records: exact hardware lane, artifact filename, byte size, SHA-256, signing key, install readiness, known limitations and review date. This page carries the artifact table inline so you can verify a download without leaving it.

Current release — beta20260709 (guarded experimental)

Signed experimental artifacts for the Antminer S9 (Zynq/XIL1) and S19j Pro (Zynq/XIL3) lanes. Guarded-artifact status: the S9 route remains lab-gated pending a witnessed current-artifact install/boot/soak/recovery capstone; the S19j Pro package has guarded DCENT_OS-source self-update evidence only — vendor-stock first installation is an open evidence gap. Not production-ready. Use only on spare hardware with a proven recovery route.

Each sysupgrade package additionally embeds a signed manifest verified against the beta release public key 26985575eae77d56c490ceeb9054af012eab5ae59119cd20eaa70dd7e722df83 (published on the artifact index). Step-by-step walkthrough: firmware verification guide.

Provenance notes

The two .tar sysupgrade artifacts are also published as GitHub release assets on the DCENT_OS releases page; the S9 SD image is published on this download host.
No detached SHA256SUMS.txt.sig/.asc exists on the host — the signing story is the embedded per-package manifest plus the published public key, not a detached GPG signature. We say that plainly rather than imply otherwise.
Presence of a file is not a general install instruction — install readiness is path-specific. Read the release evidence record and the per-model ledger before any persistent write.

Published release records

beta20260709 — guarded experimental artifacts for S9 Zynq/XIL and S19j Pro Zynq/XIL; not production-ready. Full lane-by-lane evidence, limitations and review history on the record page.

Where to go from a download

Artifact digests transcribed from downloads/dcent-os/beta-20260709/SHA256SUMS.txt; byte sizes verified against the download host's HTTP Content-Length; signing key and guarded-artifact language from the artifact index page (all fetched 2026-08-13). The artifact directory itself is noindex — this page is the indexable record.
