On June 26, the Truman Center and the Coinbase Institute hosted the fourth session of a four-part roundtable series on Technology and National Security, focusing on market structure legislation, including the Digital Asset Market Clarity (CLARITY) Act of 2025. We explored how this landmark legislation can position the U.S. to lead in the next era of the global digital economy. By creating a clear, comprehensive regulatory framework for digital assets, market structure legislation can help strengthen U.S. economic competitiveness and ensure that innovation and jobs in this rapidly growing sector remain onshore. Our discussion focused on how thoughtful regulation can guide the development of blockchain and crypto technologies in alignment with American values—reinforcing financial stability, protecting consumers, and securing U.S. leadership in a strategic domain.
