Virgin founder and entrepreneur Richard Branson has publicly voiced praise for wallet provider Blockchain.

In a blog post Monday, Branson, who invested in the startup’s recent Series B funding round, also complimented co-founders Peter Smith and Nicolas Cary.

“What we like is that the Blockchain team, run by co-founders Peter Smith and Nic Cary, have built a platform that will allow them to be the custodian of any digital assets should alternate use cases of Blockchain technology reach critical mass,” he wrote.

Blockchain’s latest funding was a considerable success and marked the largest such round ever by a Blockchain company.

Announced mid-June, contributions also came from Lightspeed Venture Partners including early Snapchat investor Jeremy Liew, who like Branson also participated in the Series A round in 2014.

“While our hypothesis about Blockchain technology adoption is in its infancy, we are excited to be backing the entrepreneurs behind Blockchain,” Branson continued.

“We’ve had to change course in many Virgin businesses over the years as industries have evolved. So it is important when making early stage investments to be backing the smartest entrepreneurs, who know how to deal with these changes.”

He added he “certainly” didn’t know “how emerging payment technologies are going to change the world” in future.
