Cryptocurrency millionaire Jeffrey Berns has revealed plans to develop a large parcel of Nevada's desert into a smart city powered by blockchain technology.
Berns, who made a fortune selling cryptocurrency last year, plans to transform the 67,000-acre (27,113-hectare) plot in the north of the US state after paying reportedly paying $170 million (£130 million) for the land.
The site known as Innovation Park, which neighbours hubs of major tech giants including Google, Apple, Switch and Tesla, is already home to the headquarters of his company Blockchains ? an incubator that supports ventures and businesses using blockchain technology.
City will be "new kind of business and residential community"
A blockchain is a set of digital records that track transactions chronologically and publicly. These decentralised ledgers ? not tied to a particular government or authority ? facilitate digital currencies (cryptocurrencies) like Bitcoin and Ether. Berns made his millions buying and selling Ether tokens, which are used on a computing platform called Ethereum, before their value crashed.

He now intends to use the money to develop the remainder of his land into a smart city, billed as "a new kind of business and residential community".
The proposed blockchain city is intended to pioneer uses for the technology in an urban environment, including houses, schools and a high-tech park for Berns' company.
