Odaily News The Arkansas Crypto Mining Association filed a lawsuit against state Attorney General Tim Griffin and Oil and Gas Commission Director Lawrence Bengal in the U.S. District Court for the Eastern District on March 13, accusing them of enforcing unconstitutional and discriminatory state regulations that prohibit foreign-born U.S. citizens from engaging in crypto mining activities. Previously, a federal court temporarily prohibited Arkansas from preventing a naturalized Chinese American citizen from operating a crypto mining business in November last year. (Cointelegraph)
