Canaan Inc. has secured an additional order from Tether for custom Bitcoin mining hardware, enhancing their collaboration on immersion cooling systems. The agreement involves supplying high-density hash board modules for a Tether-associated facility in South America. This builds on Canaan's previous R&D efforts with ACME Swisstech, aimed at improving mining efficiency and scalability. Tether, the issuer of USDT, is also developing integrated management software for its mining operations, signaling a move towards more customized, data center-style Bitcoin mining. The agreement includes an option for Tether to expand its infrastructure based on system performance. Meanwhile, Canaan's stock saw a slight decline, reflecting broader market trends affecting Bitcoin mining stocks.
