Bitcoin News Today: U.S. Blockchain Firm's Teraflux ASICs Challenge China's Bitcoin Mining Supremacy

Auradine Inc., a U.S.-based blockchain technology firm, has unveiled its third-generation Teraflux Bitcoin mining application-specific integrated circuits (ASICs), touting an energy efficiency of 9.8 joules per terahash (J/TH)—among the lowest in the industry, according to The Block. The new lineup, introduced in a November 2025 press release and detailed by The Block, represents a strategic push by the California-based company to challenge China-dominated rivals like Bitmain Technologies.

The Teraflux series includes air, hydro, and immersion-cooled models, with the immersion variant achieving 9.8 J/TH in "eco mode" and 10.7 J/TH in normal mode, as The Block notes. Air-cooled units operate at 11 J/TH (normal) and 10.3 J/TH (eco), while hydro configurations match the eco mode efficiency of 9.8 J/TH. Auradine emphasizes that its hydro and immersion models directly compete with Bitmain's Antminer S21 Hydro U3 and S23 Hydro, which hover around 9.5–11 J/TH, according to Hashrate Index data.

The firm's U.S. credentials are central to its value proposition. With global supply chains strained by Trump-era tariffs and geopolitical tensions, Auradine positions itself as a domestic alternative to overseas manufacturers. "For too long, miners have had to choose between performance and reliability. We have now finally closed that gap," said CEO Rajiv Khemani in a statement. The company, which raised $153 million in a Series C funding round led by StepStone Group, claims its machines power over 40 major data centers, including MARA Holdings, as The Block reports.

Auradine's hardware is paired with FluxVision, an upgraded fleet management software suite offering real-time metrics, automated curtailment scheduling, and secure pool configurations. A mobile app, set for release on app stores in late 2025, will allow operators to monitor and control mining operations remotely. The platform's "SMART" architecture promises resilience, enabling continued operation even with multiple chip failures, as The Block describes.

While the Teraflux series lags behind Bitmain's highest-output models—such as the Antminer S21 Hydro U3's 1,160 terahashes per second (TH/s)—it outperforms mid-tier competitors like the Sealminer A3 Pro Hydro (660 TH/s) and Antminer S23 Hydro (580 TH/s). Hydro and immersion models max out at 900 TH/s, with air and immersion units reaching 310 TH/s and 360 TH/s, respectively, according to Hashrate Index.

Initial Teraflux samples are slated for Q2 2026, with mass production beginning in Q3 2026. Auradine's press release highlights partnerships with firms like GDA and Allrise Capital, which praised the product's efficiency and ease of deployment, as The Block reports.

The launch comes amid a broader reshaping of the Bitcoin mining landscape. While U.S. firms like Auradine seek to capitalize on domestic demand, geopolitical tensions—such as China's recent accusations that the U.S. government orchestrated a $13 billion Bitcoin theft—underscore the volatile regulatory environment, as Hashrate Index has covered. Auradine's focus on energy efficiency and U.S. manufacturing aligns with industry trends toward sustainability and supply chain diversification.
