New Hampshire Governor Kelly Ayotte has signed the "Blockchain Foundation Act" (HB 639), enhancing legal protections for blockchain developers, miners, validators, and crypto users. The legislation, signed last week, also establishes a specialized blockchain dispute tribunal within the state's Superior Court. This move aims to safeguard digital asset control through self-custody and provide a clear legal framework for fintech enterprises. State Representative Keith Ammon, the bill's primary sponsor, emphasized that the law is designed to attract entrepreneurs, investors, and developers by offering a supportive environment for next-generation financial technologies. This follows New Hampshire's earlier initiative in May 2025, when it became the first U.S. state to pass a strategic Bitcoin reserve bill, permitting the state treasury to invest up to 5% of public funds in Bitcoin and precious metals.
