PAC Protocol CEO David Gokhshtein told Sky News it will only take two to three years for a “decentralised” version of the internet to take over and those who don’t adapt “will be left out”. Companies such as PAC Protocol are currently developing applications built around blockchain which may soon challenge Google, Microsoft and other tech giants in how data is managed. “I mean technology, it moves fast so at the end of the day those that don’t adapt, they’ll be left out,” Mr Gokhshtein said.
