Ethereum’s Vitalik Buterin Calls for On-Chain Transparency at X

Ethereum ETH $2,832.52 co‑creator Vitalik Buterin suggested that the social platform X could use blockchain and zero‑knowledge proofs (ZK‑proofs) to make its algorithm transparent and resistant to censorship.

This idea was shared in an X post on December 15, which noted that content‑ranking decisions could be verified on‑chain to demonstrate fairness.

The proposal included timestamping posts, likes, and reposts on a public ledger so the platform could not manipulate timing or visibility.

Buterin also addressed concerns about how Elon Musk's leadership of X affects freedom of expression.

He stated that turning the platform into a "global totem pole for free speech", yet allowing it to "become a death star laser for coordinated hate sessions", undermines the principle of free communication.

Additionally, Buterin backed the idea put forward by the Ethereum Foundation's AI lead, Davide Crapis, who called for greater openness from X.

Crapis emphasized that if the platform claims to support free speech, it must state its algorithmic objectives. He called for users to be able to understand and adjust those goals.

One part of the proposal involves using ZK proofs to verify that every algorithmic choice on X adheres to predefined rules, without revealing confidential data.

Buterin further suggested that the entire algorithm code be published with a delay of one to two years.

Buterin recently shared an idea to help users plan for changing network fees. What did he say? Read the full story.
