blockchain technology; tax; fee; prohibition

Arizona's SB 1045 prohibits cities and counties from banning or taxing individuals who run blockchain technology nodes (home-based computers validating transactions) in their residences. The bill explicitly prevents local governments from imposing restrictions or fees on residential blockchain operations, stating such regulation is a statewide concern. It defines key terms like "computational power" (using hardware/software for tasks like blockchain processing) and "running a node" (validating transactions). The law directly affects residential users of blockchain technology, ensuring they cannot face local barriers or costs for this activity.
