TL;DR
The bill creates a voluntary “Mined in America” certification for mining operations.
It codifies the Strategic Bitcoin Reserve within the Treasury Department into law.
NIST and manufacturing programs will support U.S.-made energy-efficient mining machines.
On March 30, 2026, U.S. Senators Bill Cassidy (R-LA) and Cynthia Lummis (R-WY) put forward the Mined in America Act. The legislation has two main goals. First, it pushes digital asset mining operations back onto U.S. soil. Second, it writes President Trump’s executive order on a Strategic Bitcoin Reserve into law.
The bill targets a weak spot in the supply chain. According to the Satoshi Action Fund, a group supporting the bill, the United States controls 38% of the world’s Bitcoin hash rate. But here is the problem. 97% of the mining hardware used to produce that hash rate comes from China.
Senators Cassidy and Lummis call this a national security risk. The bill tries to break that dependency.
What the Legislation Does
The Mined in America Act directs the Department of Commerce to create a voluntary certification program. This program is called “Mined in America.” It applies to cryptocurrency mining facilities and mining pools.
Certified operations must switch away from equipment linked to foreign adversaries. The bill does not create new federal spending authorities. Instead, it connects certified projects into existing federal energy and rural programs.
The legislation also gives tasks to two agencies. The National Institute of Standards and Technology (NIST) and the Manufacturing Extension Partnership must support U.S. manufacturers. The goal is to help those manufacturers build energy-efficient mining hardware.
A fifth part of the bill formally sets up a Strategic Bitcoin Reserve inside the Department of the Treasury. This provision codifies Trump’s earlier executive action, turning it from an order into a permanent law.
The bill’s backers say the current setup leaves the U.S. exposed
An excerpt from the bill cites Dennis Porter, CEO and Co-Founder of the Satoshi Action Fund. Porter said the legislation “breaks that dependency by building a virtuous cycle of domestic manufacturing, certified mining operations, grid-strengthening energy infrastructure, and a pipeline to the Strategic Bitcoin Reserve.” He added, “We cannot let adversaries hold the keys to our supply chain.”
That last line carries a connotation. The keys are not literal. But the image fits. Whoever controls the hardware controls the flow of new Bitcoin.
If the bill passes, it would change how the U.S. handles Bitcoin mining security
Right now, American miners buy most of their machines from Chinese manufacturers. Those machines are expensive. They are also hard to replace. A disruption in trade or a hidden backdoor in the hardware could hurt U.S. mining operations.
The voluntary certification program aims to fix that. Miners who join the program would get a label. That label says their equipment is free from foreign adversary parts. Over time, the bill phases out old hardware from certified facilities.
The bill also ties mining to existing energy programs. That means miners could get help with power costs. They could also help balance the electric grid. Some mining operations already shut down during peak demand. The bill encourages that kind of coordination.
The Strategic Bitcoin Reserve provision stands out
It takes an executive order and makes it law. That gives the reserve more stability. A future president cannot simply undo it with another order. For U.S. hardware makers, the bill offers a push. NIST and the Manufacturing Extension Partnership will provide technical help. But the bill does not hand out cash. Companies must build the machines themselves.
The bill faces an uncertain path. Some lawmakers may question whether the government should certify mining facilities at all. Others may worry about trade retaliation from China.
Still, the numbers speak for themselves. The U.S. mines more Bitcoin than any other country. But the machines that do the work come from a rival. That gap is what the Mined in America Act tries to close.
The bill was introduced on March 30. It now heads to committee for review.
