This bill establishes a new chapter titled "Blockchain Basic Laws" in New Hampshire's legal code to protect blockchain technology and its users, thereby enhancing investor and consumer confidence. Key provisions include the creation of a blockchain dispute docket, definitions for terms such as "blockchain," "digital asset," and "smart contract," and protections for individuals and businesses involved in blockchain activities. Notably, the bill prohibits state or local government agencies from restricting the use of digital assets for transactions and from imposing discriminatory electricity rates on digital asset mining businesses. It also allows home digital asset mining without specific sound limits beyond existing noise ordinances and exempts certain blockchain activities from needing a money transmitter license.

Additionally, HB 639-FN clarifies that digital asset mining and staking services will not be classified as securities or investment contracts under RSA 421-B, and it introduces legal language that protects businesses from liability for validating transactions. Individuals affected by violations can seek relief through the superior court or the new blockchain dispute docket, which will handle related disputes with the consent of the parties involved. The bill includes a severability clause to maintain the enforceability of remaining provisions if any are invalidated. The effective date for the blockchain dispute docket is set for January 1, 2026, while other provisions will take effect 60 days after passage. The fiscal impact remains uncertain, with potential increased litigation costs and a possible loss of revenue for the Bureau of Securities due to limited regulatory authority over digital asset services.
