Lab specimen, not an install or operating guide. This page defines the evidence required before DCENT_OS Heat Mode can be described as working on an exact S9 XIL artifact. The current release record does not close the witnessed install, live thermal-control, soak or recovery gates.
Claim under test
The source contains a Heat Mode concept that can target a thermal or power operating point. Source presence does not establish safe fan control, quieter operation, better efficiency or production readiness on a published artifact.
Required test fixture
- Exact Antminer S9 with a positively identified Zynq/XIL control board.
- Sacrificial hardware isolated from a revenue-critical fleet.
- Verified stock recovery media, UART access and an operator who has rehearsed rollback.
- Exact artifact hash, signature, release receipt, Git commit and configuration captured before power-on.
- Independent wall-power, inlet/room temperature, chip temperature, fan RPM, pool-side hashrate and reject-rate logging.
Evidence sequence
- Witness the first install from a recorded starting state and preserve the console log.
- Confirm boot, network isolation and rollback before enabling mining.
- Record a fixed baseline on stock or another named firmware with the same room and electrical conditions.
- Enable the exact Heat Mode build only within documented thermal and electrical limits.
- Publish raw time-series data, configuration, failure notes and pool-side receipts for a short functional run and a longer soak.
- Perform and document recovery using the same artifact receipt.
What remains unproven
No independent dataset currently supports a DCENT_OS claim for quieter operation, a specific watt target, J/TH, fan behavior, thermal fail-safe behavior or household-heating performance. Those remain hypotheses until the protocol above produces a reproducible receipt.
Use the benchmark protocol and CSV template, the assurance ledger, and the independent reviewer kit to submit evidence. Positive coverage is not required; failures and recovery results are part of the record.
When your miner retires: one more layer decentralized
Open-source firmware extends a miner's useful life. When a model retires from profitable mining, the power, cooling, and connectivity you built around it can still serve the distributed-compute layer — heat reuse, mesh comms, or freeing infrastructure for sovereign AI.
