MDK Framework Draws Integration Pledges From Miners
By Scarlett · Chief of Staff · 25 Oct 2026
Fifteen Bitcoin mining operators, hardware makers and pools committed to building integrations for MDK, an open-source framework that gives mining equipment from different vendors one common interface.

How it works
Each participant builds and maintains an MDK Worker. The Worker acts as a translation layer that connects a company’s existing hardware, pool or system to MDK. It converts the company’s interface into a common language that MDK applications understand. Companies decide which functions to expose through the Worker. They keep their own technology in place and retain control of their systems. The MDK orchestration kernel communicates only with Workers through a shared message set known as the MDK Protocol. It never connects directly to individual devices. This structure lets developers write one application, monitoring system or AI agent that works across multiple vendors without separate integrations for each one.
Background
A large mining site often runs thousands of machines from different manufacturers. Those machines connect to different pools and run under different management software. The systems were rarely designed to share data or commands with one another. As a result developers spent repeated effort rebuilding similar connections for each new piece of equipment or pool software. MDK addresses that pattern by providing a single set of messages and a consistent interface that every participant can support.
Why it matters
When more companies maintain their own Workers the same application gains reach across a larger portion of the mining industry. An AI agent or monitoring tool written once against MDK can then operate on hardware and pools from many sources without further changes. The framework reached version 0.11 during a Bitcoin forum held in Lugano, Switzerland on October 23 and 24, 2026. A stable 1.0 release remains targeted for the end of 2026. MDK is released under Apache 2.0 terms. Developers can already test integrations, build Workers and create applications through the public repository and documentation. The documentation includes a demo environment that contains mock hardware, a gateway and a dashboard. The project stays open to any manufacturer, mining pool, operator or developer who chooses to participate.
The commitments announced on October 24, 2026 include hardware makers Bitmain, Canaan and MicroBT along with mining pools such as Foundry Digital, F2Pool, Luxor Technology, OCEAN, EMCD and SpiderPool. Additional participants are Bitdeer, Proto which is part of Block Inc., ACME Swisstech, Elektron Energy, Heatbit and Stratum V2. Each of these groups will maintain its own MDK Worker. Tether developed the framework and announced the set of commitments. Its own QVAC mining agent already runs directly on MDK. As the number of active Workers grows, applications built on the framework can reach an expanding share of active mining capacity without additional per-vendor work.
