Gambar Vitalik Buterin Raises Concerns Over X’s Algorithm, Transparency Seen as Key to Public Trust

Jakarta, Pintu News – Ethereum founder Vitalik Buterin has called for algorithm transparency on social media platforms to increase user trust and ensure fairness in information dissemination.

With the rise of online hate, especially in Europe, Buterin proposed using zero-knowledge proofs to verify fairness without revealing users’ personal data.

Algorithm Transparency for User Trust

Vitalik Buterin, founder of Ethereum, emphasized the importance of social media platforms to publish the algorithms they use. This aims to create transparency and build trust among users. Buterin argues that users deserve to know how the system is designed to promote or suppress certain types of content.

@elonmusk I think you should consider that making X a global totem pole for Free Speech, and then turning it into a death star laser for coordinated hate sessions, is actually harmful for the cause of free speech. I'm seriously worried that huge backlashes against values I hold…

In an effort to maintain fairness and privacy, Buterin proposed the use of zero-knowledge proof. This technology allows platforms to prove that their systems operate fairly without having to reveal users’ personal data. This is a step forward in protecting privacy while ensuring that algorithms work without bias.

Balance between Security and Transparency

Buterin also proposed that the algorithm code be made public after a lag of one to two years. This approach is designed to maintain a balance between transparency and security. This way, the public can review how decisions are made without providing opportunities for direct abuse of the system.

According to Buterin, with platforms like X managing hundreds of millions of posts every day, this delayed transparency will help users and researchers better understand how content decisions are made over time. It will also prevent possible censorship or manipulation that is invisible to the platform.

Potential Replies to Freedom of Speech

The attacks on Europe I've seen here the last couple of days, including from people I've generally considered interesting and sophisticated, have been getting unhinged…

I get that EU has problems – GDPR clickthroughs are dumb, Chat Control is awful, they need to be less…

Buterin expressed his concerns about the future of free speech on large social media platforms. He warned that platforms that become tools for organized harassment could trigger a backlash from the public and ultimately harm the idea of free speech itself.

In addition, Buterin also highlighted the increase in online hate targeted primarily at Europe. He emphasized that these exaggerated attacks that don’t match his personal experience use exaggerated stories to attack the region as a whole.

Conclusion

Transparency and fairness in the management of algorithms by social media platforms are key to rebuilding public trust and maintaining an open conversation space. With the approach proposed by Vitalik Buterin, there is hope that these platforms can be more responsible and fair in managing the content presented to users.

FAQ

Vitalik Buterin calls for social media platforms to increase algorithm transparency to build trust and ensure fairness in content distribution.

Why is algorithm transparency important?

Transparency helps users understand how content is promoted or suppressed, while reducing the potential for bias and manipulation of information.

What are Buterin’s zero-knowledge proofs?

Zero-knowledge proofs are cryptographic technologies that allow verification of the fairness of the system without revealing the user’s personal data.

Why is it recommended to publish algorithm code with a time lag?

The one to two year lag aims to maintain a balance between public transparency and the security of the system from abuse.

What are Buterin’s concerns regarding freedom of speech?

Buterin is concerned that organized harassment and online hate could lead to excessive restrictions that harm free speech.
