Zukerberg on using Blockchain based authentication

In an interview with Harvard law professor Jonathan Zittrain Facebook creator and CEO Mark Zuckerberg said that Facebook is considering using the blockchain in authenticating users of various web services without relying on third parties.

According to Zuckerberg Facebook is considering a potential use of the blockchain in which users can control their data.
“I think about how it would be possible to use the blockchain technology in the authentication processes and in providing access to user data for various services, but at the moment I don’t completely understand the options for implementing this idea. The functions that Facebook Connect currently performs can be shifted to something truly distributed. In essence, the user enters his data into a decentralized system and subsequently uses it for authentication, while not resorting to third parties. ” Zukerberg said.

But there are also disadvantages in the application of a decentralized system like the lack of ability to counteract the attackers.
Over this Zukerberg said that a decentralized system can give users greater control over their data but can also lead to more abuse and any recourse to help will be much more difficult to implement than in a centralized system.

The creator of Facebook also said that it would take a lot of effort to implement such an idea since there are technical obstacles associated with decentralized technologies.

“Undoubtedly, Facebook processes a large amount of data. But a decentralized solution requires even more computation. To conduct them in a distributed registry is more difficult, although in the end the amount of available resources should be enough. ”

Zuckerberg said that one example of how a company is moving toward a more decentralized structure is to provide encryption in its messaging services.

At the beginning of this month Facebook bought a blockchain-startup called Chainspace. Reportedly Facebook acquired this startup mainly for the skills and experience of its employees and not for the services or products that the company provides.
