The U.S. economy and financial systems are increasingly relying on cryptocurrencies. The surge in the value of Bitcoin (BTC) is attributed to the introduction of exchange-traded funds providing access to a vast new consumer base. This trend is generally positive.
However, the growing prominence of Bitcoin also necessitates enhanced regulatory measures, similar to those required by other emerging technologies like AI. In a globally interconnected world where national security concerns are heightened by each new disruptive technology, it is imperative to address risks associated with critical network and infrastructure vulnerabilities promptly.
China’s potential threat looms large in these discussions. Past perceived technological threats from entities such as Huawei, TikTok, and Chinese electric vehicle manufacturers prompted decisive actions by the U.S. The risk posed by Bitcoin miners is even more concerning, as they could potentially function as covert, integrated hardware components within U.S. energy and telecommunications infrastructure.

Given the extensive risks involved, regulatory bodies must act promptly to prevent Chinese crypto mining technology from jeopardizing vital U.S. utility and financial systems.
Bitcoin mining involves the process of introducing new Bitcoins into circulation. It serves as a means of securing the network by verifying and validating all transactions on the blockchain, the underlying public ledger of Bitcoin. Miners engage in a competition to solve intricate mathematical problems, with the first successful solver adding the next block to the blockchain and receiving newly minted Bitcoins and transaction fees as rewards.
Requiring substantial computational power and energy input, Bitcoin mining is performed through sophisticated mining rigs, which are high-performance computing systems powered by advanced semiconductors known as ASICs. China currently holds a dominant position in supplying ASICs for Bitcoin mining, accounting for 98% of the current chip supply, primarily through a few major manufacturers such as Bitmain. These chips, designed in China, are manufactured by TSMC, utilizing their latest and most sophisticated manufacturing process (3nm).
This poses a significant challenge to U.S. trade policies and competitiveness, in addition to the inherent risks to national security.
The U.S. has imposed tariffs on Chinese imports due to ongoing trade disputes. However, some Chinese companies, including Bitmain, circumvent these tariffs by establishing subsidiaries or affiliates in other countries and resorting to aggressive dumping and price-cutting tactics that significantly impede the adoption of U.S.-based ASIC suppliers. This undermines not only the tariffs but also efforts like the CHIPS Act, which aims to boost domestic semiconductor manufacturing in the U.S.
As the number of mining facilities in the U.S., many of which are also Chinese-owned and powered by China-manufactured miners, continues to grow rapidly, concerns among national security experts over their proximity to critical U.S. infrastructure have escalated. A primary fear is that these facilities could act as Trojan horses, enabling Chinese intelligence agencies to engage in cyber-espionage by potentially targeting sensitive military installations, power grids, or communication networks.
Chinese companies, both state-owned and private, operate under a legal framework that mandates cooperation with China’s intelligence services upon request. This raises concerns about Chinese authorities leveraging their influence within seemingly innocuous crypto mining operations to gather valuable data on U.S. domestic affairs.
Moreover, the intricate nature of crypto mining equipment introduces potential vulnerabilities through backdoors. Some experts caution that hardware manufactured in China could contain concealed security backdoors in the firmware or software of the miners, enabling covert data transmission or even remote sabotage of critical infrastructure.
The increasing significance of Bitcoin and related blockchains in the U.S. financial system and economy cannot be overlooked. It is estimated that 40% of U.S. adults hold some form of crypto, and the Bitcoin mining industry is expected to grow at a 9% compound annual growth rate through 2029. The adverse effects of a major disruption in trading, mining operations, or price stability will only escalate.
Unfortunately, relying on Chinese suppliers for validating Bitcoin transactions poses a significant risk to the U.S. financial system. With China’s substantial presence in the U.S. crypto mining sector, there is a possibility that China may seek to influence or disrupt its operations during times of heightened tensions. For instance, if China were to restrict the import of Bitcoin mining rigs to the U.S. or utilize its sway over Chinese suppliers to manipulate the Bitcoin network, it could disrupt the functioning and stability of…
