Bitcoin Mining Firmware Feature Matrix Dataset — Stock vs BraiinsOS+ vs VNish vs LuxOS vs DCENT_OS

Maintained firmware feature dataset

This public CC BY 4.0 registry compares stock Bitmain firmware, BraiinsOS+, VNish, LuxOS and DCENT_OS. Every DCENT_OS cell is paired with an interpretation that separates source capability or target status from exact artifact, mining, install and production evidence.

Bitcoin mining firmware feature matrix

This registry compares stock Bitmain firmware, BraiinsOS+, VNish, LuxOS and DCENT_OS. Competitor cells describe documented product behavior. A DCENT_OS value marked ‡ is a source capability or target only unless the adjacent interpretation and an exact release record say otherwise; it does not establish artifact readiness, install readiness or production support.

Related firmware surfaces

This dataset models the established production firmwares. For the decisions it does not model: the firmware comparison hub is the declared hub for this cluster; model hubs cover the Antminer S19 XP, Antminer T21, Lucky Miner and Hammer Miner; download verification lives in the mining firmware security guide; native SV2 on Bitaxe in the setup guide with the AxeOS API reference beside it. New-entrant coverage: Mujina, explained.
