DCENT_OS beta20260709 Release Evidence
All 13 registry models are Released/Experimental. beta20260709 is the current dated prebuilt-artifact set, not a production-support qualification. It contains SHA-256 receipts for exact S9 Zynq/XIL and S19j Pro Zynq/XIL files; the two sysupgrade packages authenticate their embedded payload manifests with Ed25519.
Build and provenance receipt
| Website artifact label | beta20260709 |
|---|---|
| GitHub release pointer | v0.3.0, published 13 July 2026. GitHub points at commit a24f246. |
| Version mapping assurance | The GitHub release exposes the two tar assets; the website set also includes the S9 SD image and checksum file. No signed receipt yet proves that every beta20260709 file maps byte-for-byte to tag v0.3.0, so this page records the pointer without asserting equivalence. |
| Builder image / digest | Not recorded in this website receipt. |
| Vendor input hashes | Not published here. |
| Package manifest/signature | Present inside the named packages; Ed25519 release-key fingerprint is shown below. |
| Independent rebuild | None published. |
| Install-from state | S9 first-install capstone open; S19j Pro guarded DCENT_OS-source update only, vendor-stock first install open. |
Release files and checksums
| Target | File | SHA-256 | Install status |
|---|---|---|---|
| Antminer S9 Zynq/XIL | DCENTOS_XIL1_S9_beta20260709.tar | e0bd9e30c7277a86f0c601bb882f41a7dd311160e29d7aefc4e017d2454ab845 | Bitmain's S9 recovery documentation distinguishes complete-board CRT0401/CRT0402 (JP4), CRT0302 (AB pads), and CRT0301 (no SD slot). The public DCENT_OS trial documents only the JP4 route; no other PCB revision inherits that authorization. The current public evidence still lacks a complete witnessed first-install, soak and persistent-recovery capstone for this release. |
| Antminer S9 Zynq/XIL | DCENTOS_XIL1_S9_SD_beta20260709.img | 1c61fde315ce6eadcef5df79690ed15558173c96216680970f8de3360081b266 | Bitmain's S9 recovery documentation distinguishes complete-board CRT0401/CRT0402 (JP4), CRT0302 (AB pads), and CRT0301 (no SD slot). The public DCENT_OS trial documents only the JP4 route; no other PCB revision inherits that authorization. The current public evidence still lacks a complete witnessed first-install, soak and persistent-recovery capstone for this release. |
| Antminer S19j Pro Zynq/XIL | DCENTOS_XIL3_S19jPro_beta20260709.tar | e7afc67cd9f7c9cda0bcd329f61116ef352644c3ae707741e04e1e1e5e7b2a96 | The verified package supports a guarded DCENT_OS-to-DCENT_OS update on am2-s19j. Public vendor-stock first installation remains an evidence gap, and public_beta_install is false in the source matrix. |

Known limitations
- No model or control-board lane beyond the three files above is part of this release.
- The S9 route remains lab-gated pending a witnessed current-artifact install, boot, soak and recovery capstone.
- The S19j Pro artifact has guarded DCENT_OS-source self-update evidence; vendor-stock first installation remains an evidence gap.
- Stratum V2 is not claimed for these artifacts; treat them as Stratum V1 unless exact artifact notes prove otherwise.
- No independent performance benchmark, security audit, SBOM or reproducible-build certification is claimed for this release.
Safe next step
Start with the hardware-status ledger, identify the exact board, and prove recovery before considering a persistent write. Operators with production or revenue-critical miners should use mature production firmware.
