CARSON CITY, Nev. (AP) — In the Nevada desert, a cryptocurrency magnate hopes to turn dreams of a futuristic “smart city” into reality. To do that, he’s asking the state to let companies like his form local governments on land they own, which would grant them power over everything from schools to law enforcement.
Jeffrey Berns, CEO of Nevada-based Blockchains LLC, envisions a city where people not only purchase goods and services with digital currency but also log their entire online footprint — financial statements, medical records and personal data — on blockchain.
