Mark Zuckerberg Reveals His Thoughts on Blockchain-Based Authorization


The CEO of Facebook talked to Jonathan Zittrain and discussed the potential advantages of blockchain online logins. Mark Zuckerberg shared his opinion on decentralized authentication services in the most recent interview conducted by a Law professor from Harvard.

At all, the Facebook leader remained vague about such an innovation. As it was told, on the one hand, it can be useful for software developers and users to get rid of third-party corporations which limit accesses now. On the other hand, blockchain sets a lot of challenges like more difficult recourse or high tech requirements.

In details, here are key ideas from the interview.

Potential Benefits and Changes

Zuckerberg sees blockchain-driven logins quite simply. During the interview, he revealed that it’s enough to «take your information, store it on decentralized system, and … log into places without intermediary».

Talking about technologies, Zuckerberg mentioned that he and members of his generation tend to choose products which give more power to individuals and reduce the level of centralization. Hence, fully decentralized systems can grant customers more control over their sensitive data. People will be able to protect their info with nearly unbreakable tech.

According to Facebook CEO’s opinion, this use of blockchain idea would become a competitive alternative to existing single sign-on apps like Facebook Connect. However, it’s still possible to merge two ideas and create branded decentralized solutions. For instance, Facebook already started integrating encryption features in its messaging services.

Weaknesses of the Technology

Nevertheless, Zuckerberg mentioned that there are several significant social and philosophical questions. They are related to consent, data abuse, and recourse. Say, with blockchain systems, it’s much harder to roll back changes or return missed/stolen information. «Do you really want that?», asks Mark…

Lastly, Zuckerberg noted the tech side of the discussed innovations. Despite he considers them as secondary to moral issues, there are no doubts that Facebook barely can handle computational tasks of decentralized systems. Blockchain-related processes are harder than the existing project’s stuff but eventually it will be possible to handle them, as well.

Upcoming Innovations

We don’t know the real plans of Facebook blockchain groups but we do remember that the company has recently consumed Chainspace, a startup focused on scalability and smart contracts. The team tries to find a solution to poor blockchain-based platforms’ stability when they are under load. It seems that Facebook is more interested in tech knowledge of Chainspace’s members rather than on their products.
