Senate Children and Youth Committee hears experts warn bitcoin mining may strain power grid and raise security concerns

At a Sept. 4 meeting of the Senate Committee on Children and Youth in Little Rock, two experts told lawmakers that expanding bitcoin mining facilities can put pressure on local energy systems and raise national security concerns because of increasing foreign control of mining operations and associated power contracts.

Adam Zarazinski, co‑founder of Inca Digital, and Anita Nikolich, director of research and technology innovation at the University of Illinois Urbana‑Champaign, presented Exhibit B to the committee, summarizing trends in bitcoin mining facilities and their potential impacts on the electricity grid. The presenters said the concentration of ownership and the growth of data‑center‑scale mining operations have increased the risk that mining could disrupt local grid stability and create strategic vulnerabilities.

The presenters highlighted particular concern that “bitcoin mining activities can cause a potential national security threat,” pointing to the expanding control and ownership of mining operations and power contracts by foreign companies. Zarazinski and Nikolich described that trend as a point of risk for both energy reliability and broader security considerations.

Senator Bryan King, the committee chair, called the meeting to order. The record lists Senators Alan Clark (vice‑chair), Matt McKee, Clint Penzo, Dan Sullivan and John Payton as present; no formal motions or votes were recorded on the cryptocurrency presentation. The committee adjourned at 1:30 p.m.

The record notes Exhibit B and Exhibit B1 as materials for the presentation; the transcript does not include further technical data, specific local grid studies, or proposed legislative actions. The committee did not record any formal direction to staff or a vote on follow‑up steps during this session.
