Summary

At a Senate Armed Services Committee hearing on April 22, 2026, Admiral Samuel Paparo emphasized Bitcoin's proof-of-work technology as a significant asset for cybersecurity, stating it imposes higher costs on attackers. He described Bitcoin as a 'peer-to-peer zero-trust transfer of value' that supports US national security interests beyond its monetary applications. Paparo's comments align with previous statements from US Space Force member Jason Lowery, who noted Bitcoin's potential to secure various forms of data and communications. The discussion occurred amidst rising cyber threats from state-linked actors, particularly North Korea's Lazarus Group, which has stolen billions in cryptocurrency. The US currently holds the largest Bitcoin reserves and has the highest Bitcoin hashrate among nation-states, but it relies on foreign-manufactured mining equipment, raising supply chain security concerns. Recent legislative efforts, such as the Mined in America Act, aim to bolster domestic Bitcoin mining capabilities. Key Points: • Admiral Paparo highlighted Bitcoin's proof-of-work technology as a cybersecurity asset. • The US holds the largest Bitcoin reserves and has the highest hashrate among nations. • Legislative efforts are underway to enhance domestic Bitcoin mining and reduce supply chain risks.
