US presidential candidate and cryptocurrency firebrand John McAfee will use a soon-to-be launched Perth blockchain technology in his bid for the White House in 2020.

ClearPoll, which was developed using the same technology that underpins Bitcoin, allows users to anonymously create and vote on opinon polls and is pitched at replacing the opinion surveys commissioned by the news media during election campaigns.

ClearPoll director and co-founder Daniel Abela said the technology would allow polls to be created then stored on a blockchain, which would be accessible by any user and prevent results being hidden or altered.

He said the technology would create a system more trustworthy than current methods of opinion polling.
