Facebook CEO and founder Mark Zuckerberg thinks of blockchain as a tool for users to log in to services via one set of credentials without relying on third parties. A blockchain-based solution can beat the single sign-on (SSO) technology which is utilized by, Facebook Connect, for example. Mark shared his thoughts on this during a recently posted video interview with Harvard Law professor Jonathan Zittrain.
“A use of blockchain that I’ve been thinking about … is around authentication and… granting access to your information to different services. So, replacing the notion of what we have with Facebook Connect with something that is truly distributed,” Zuckerberg said. According to him, this would allow Facebook users to enforce control of the apps that access their data, profiles, and pages.
Zuckerberg added though that he hasn’t figured out yet a particular way to utilize blockchain technology here.
Saying that Facebook can integrate blockchain technology into the platform’s login and data sharing systems, its CEO pointed that blockchain would allow developers to build applications and features without having to worry about losing access if they violated third-party policy.
“For developers, one of the things that is really troubling about working with our system, or Google’s system for that matter, or having to deliver services through Apple’s App Store is that you don’t want to have an intermediary between the people who are using your service and yourself. Where someone can just say hey, we as a developer have to follow your policy, and if we don’t, then you can cut off access to the people we are serving. That’s kind of a difficult and troubling position to be in,” CCN quoted.
Facebook CEO also noted that a decentralized system not only gives users more control over their data but could also lead to more abuse. “The question is, do you really want that? Do you have more cases where yes people would be able to not have an intermediary but there’d be more instances of abuse and recourse would be much harder?” Zuckerberg said.
Last year Facebook was increasing its crypto and blockchain efforts and hiring several new team members. The company reportedly acquired Chainspace in its first apparent blockchain-related acquisition.
