This bill establishes a new chapter titled "Blockchain Basic Laws" in New Hampshire's legal code to protect blockchain technology and its users. It aims to enhance investor and consumer confidence by clarifying the legal status of blockchain technologies and promoting the state as a favorable jurisdiction for blockchain innovation. Key provisions include the creation of a blockchain dispute docket to handle related disputes, definitions of terms related to blockchain and digital assets, and protections for individuals using digital assets for transactions without facing undue restrictions or taxes. Additionally, the bill allows for home mining of digital assets while adhering to local noise ordinances and prevents local governments from imposing discriminatory electricity rates on mining businesses.

Furthermore, HB 639-FN amends existing laws to clarify that digital asset mining and staking services will not be classified as securities or investment contracts under RSA 421-B. It provides legal protections for individuals and businesses engaged in digital asset mining, stating they will not face liability for validating transactions. The bill also allows individuals affected by violations of the chapter to seek civil remedies through the superior court or the blockchain dispute docket, with provisions for reasonable attorney's fees for prevailing parties. A severability clause is included to ensure the enforceability of remaining provisions if any are found invalid. The act will take effect in stages, with the blockchain dispute docket provisions starting on January 1, 2026, and other sections becoming effective 60 days after passage.
