U.S. lawmakers are advancing efforts to strengthen domestic digital infrastructure as Senators Bill Cassidy and Cynthia Lummis introduced legislation on March 30 to expand U.S.-based digital asset mining and formalize a national bitcoin reserve strategy.

U.S. Senator Bill Cassidy (R-La.) stated:

“Digital asset mining is a big part of our economy. We should be doing it here in America.”

He described the Mined in America Act as a measure designed to secure supply chains, reinforce domestic manufacturing, and strengthen the broader digital asset sector.

The proposal includes five key provisions. First, it establishes a voluntary “Mined in America” certification through the Department of Commerce for mining facilities and pools. Second, it requires certified operations to phase out hardware linked to foreign adversaries. Third, it leverages existing federal energy and rural development programs instead of introducing new spending. Fourth, it supports domestic manufacturing through guidance from the National Institute of Standards and Technology and the Manufacturing Extension Partnership. Fifth, it formalizes a Strategic Bitcoin Reserve within the Department of the Treasury.

U.S. Senator Cynthia Lummis (R-Wyo.) explained:

“President Trump pledged to make the United States the digital asset capital of the world— and we’re not backing down.”

She added that the legislation introduces forward-looking policies aimed at anchoring digital asset innovation domestically while supporting long-term financial stability, with a focus on reducing foreign dependency and strengthening U.S. competitiveness in the digital asset sector.

Satoshi Action Fund CEO and co-founder Dennis Porter highlighted supply chain concerns, noting that while the United States accounts for a significant share of global bitcoin hash rate, the majority of mining hardware originates from China, creating potential vulnerabilities. The proposed framework aims to address those risks by fostering domestic production, strengthening infrastructure resilience, and positioning the United States as a central player in the evolving digital asset economy. “If we are serious about leading on Bitcoin, we cannot let adversaries hold the keys to our supply chain,” he stressed.
