Isle of Man launching cryptocurrency business register
The Isle of Man is looking to create a register of digital currency businesses based on the island using its own local blockchain.
The Manx government's Department of Economic Development will be assisted by local firm Pythia in setting up the protocol using the blockchain technology.
"This initiative demonstrates both the wider applications of the blockchain technology and the Isle of Man's commitment to create the right environment for responsible digital currency businesses to prosper," said Peter Greenhill, director of e-Business Development.
There are currently more than 25 digital currency businesses based in the Isle of Man, encouraged by the local government's forward-looking attitude to cryptocurrency.
"The Isle of Man has always maintained a very positive attitude to digital currency and in line with this approach the Government are currently developing a new and wide ranging digital strategy for its own services," said Nick Williamson, founder and CEO of Pythia
