Tether, the issuer of the world's largest stablecoin, has announced a major upgrade to its Bitcoin mining infrastructure through a partnership with Canaan (NASDAQ: CAN) and ACME Swisstech. The collaboration aims to replace traditional fixed mining rigs with a modular, high-density design that enhances efficiency, scalability, and cost control across large-scale operations.
According to Tether, the new architecture separates compute, power, and cooling functions, allowing for independent optimization without requiring a complete infrastructure overhaul. This modular approach uses independent hash board modules integrated into custom control, thermal, and software systems. With immersion cooling and real-time system control, the design improves performance, reduces energy waste, and increases flexibility for industrial mining.
Tether CEO Paolo Ardoino criticized traditional Bitcoin mining methods, noting that current hardware consists of 'fixed, monolithic units in which performance, cooling, and upgrade cycles are tightly coupled.' He emphasized that these sealed units make operations more expensive. 'Tether is revising that concept by deploying modular compute that can be tuned, upgraded, and cooled independently, so we can directly control cost, efficiency, and how these systems perform at scale,' Ardoino said.
This initiative follows Tether's recent launch of the Mining Development Kit (MDK), an open-source development framework that provides Bitcoin mining operators and developers with unified control over their entire infrastructure stack. Prior to that, Tether also open-sourced its Mining OS (MOS), a mining operating system that coordinates hardware, energy, and operational data within a unified system.
