Controversial crypto advocate John McAfee is joining blockchain startup Flype as an advisor.

He hooked up with the venture at Malta Blockchain Summit last week. In a LinkedIn post, Yousif Touza, Co-founder and CEO, said: “Word about Flype spread through the entire conference, and the interest in our project was overwhelming.”

Flype is pitched as the world’s first blockchain-based, secure platform for international delivery. “John McAfee sees us as the next big thing in the sharing economy; in his words, we are the Uber of postal delivery,” Touza told Coin Rivet.
