The recent news that the U.S. military is evaluating Bitcoin as a strategic asset and exploring its practical applications is blurring the lines between digital finance and military strategy, drawing global attention. Admiral Samuel Paparo of the U.S. Indo-Pacific Command (INDOPACOM) officially stated during a Senate Armed Services Committee hearing that the U.S. military is operating nodes on the Bitcoin network. This marks the first instance of Bitcoin being deployed not merely for its economic value as a cryptocurrency, but for national security and military operations. Admiral Paparo emphasized that Bitcoin's Proof-of-Work (PoW) protocol holds significant application potential in protecting military networks and enhancing cybersecurity, foreshadowing that this technology could become a core resource in inter-state digital competition. Admiral Paparo's testimony clearly indicates that the U.S. military perceives Bitcoin not merely as a 'computer science tool,' but as a 'power projection tool' and a 'national security asset.' This is the first official confirmation that U.S. military authorities are directly participating in the Bitcoin P2P (Peer-to-Peer) network, symbolically demonstrating a shift in the U.S. federal government's stance on cryptocurrency. INDOPACOM currently oversees approximately 380,000 personnel in the Asia-Pacific region and is deeply researching Bitcoin's military applications on the main front of U.S.-China strategic competition. The Proof-of-Work mechanism offers a unique security advantage, as hacking or intrusion attempts require immense computing resources and energy. Because hostile nations or hacker organizations would have to incur astronomical costs to attack the network, this can function as an effective defense system, not only strengthening short-term security but also fundamentally blocking network intrusions in the long term. The U.S. military is leveraging these technical characteristics to experiment with data protection and network decentralization, conducting research to build resilience against cyberattacks. In particular, attention is being paid to the effect of increasing the real-world cost of cyber operations for hostile forces, and within the U.S. military, this approach is being applied to various operational scenarios for thorough review of its potential effects. These tests are reportedly expanding beyond laboratory levels to a strategic level, considering actual deployment. The U.S. military's research into Bitcoin utilization can also be seen as an attempt to establish a new military paradigm using digital technology, going beyond mere national security. U.S. Space Force Major Jason Lowery has long advocated for 'Bitcoin's national security value,' arguing for the possibility of resolving inter-state conflicts through digital competition instead of physical warfare. Major Lowery has developed a theory that the Proof-of-Work mechanism functions as a 'digital weapon,' with the potential to minimize human and physical resource damage in resolving international conflicts. While his theory was controversial among academics and military experts in the past, Admiral Paparo's testimony that the U.S. military is actually operating Bitcoin nodes and practically applying this concept clearly shows that these ideas are transforming from mere theory into tangible military strategy. Major Lowery's research presents a methodology for reducing casualties by replacing physical conflict with digital competition in military operations, while simultaneously securing a nation's strategic advantage. Similar movements are also being observed in China. It has been reported that a think tank under the People's Bank of China internally circulated a report exploring the possibility of using Bitcoin as a strategic reserve asset, clearly indicating that a new front in U.S.-China international competition is shifting towards digital assets and cryptographic technology. The potential to adopt Bitcoin as a reserve asset can directly impact not only economic aspects but also the strengthening of a nation's cyber capabilities and the establishment of international influence. In particular, the fact that both the U.S. and China are simultaneously exploring Bitcoin's strategic value carries the potential to significantly disrupt the balance of economic and military strategies within the Asia-Pacific region. This digital hegemony competition unfolds on a different dimension than traditional military or economic power struggles, and the nation that gains technological superiority is likely to seize leadership in the future international order. **The Impact of Bitcoin on South Korean Security and Digital Finance** It is therefore time for South Korea to ask itself if it is adequately prepared to respond to these global changes. South Korea holds a leading position globally in digital finance and is actively strengthening its cryptocurrency technology and blockchain industry ecosystem. Domesti
