Tether Unveils Modular Bitcoin Mining System with Open-Source Kit to Boost Efficiency
April 28, 2026
Tether is driving a broad mining-infrastructure push, launching an open-source Mining Development Kit and previously open-sourcing Mining OS to expand capabilities across software and hardware layers of bitcoin mining.
The effort centers on modular, high-density bitcoin mining systems that separate compute, power, and enclosure to enable independent tuning and upgrades, with a focus on immersion cooling.
This modular strategy is part of Tether’s broader plan to shape mining infrastructure and efficiency, not merely to increase bitcoin exposure.
Canaan and ACME Swisstech describe the project as shifting from retail, plug-and-play products to an industrial, integrated design to meet rising demand for modular, high-performance mining.
Canaan emphasizes the Avalon hash board as a core element that enables on-demand deployment and reduces operational complexity in integrated systems.
The current deal builds on a 2025 proof-of-concept under a framework with ACME Swisstech, moving customized hash boards toward production deployment.
Modular architecture aims to increase compute density, simplify maintenance, and enable easier upgrades, while optimizing thermal management for immersion cooling, with ACME Swisstech designing the integrated housing.
Co-designed with ACME Swisstech, the modular system seeks to reduce operational complexity and boost compute density for immersion-cooled mining setups.
Canaan’s stock traded around 0.493, reflecting a modest decline from the prior session.
The collaboration involves Canaan developing hash board modules and supporting control boards and mining-management systems as part of a broader concept focused on application-specific modules rather than fully assembled rigs.
The project is a joint effort with Canaan and ACME Swisstech to build mining systems around application-specific hash board modules within a modular, multi-layer hardware stack.
Immersion cooling is the primary cooling method, with other cooling options under development.
