Elon Musk said X will open-source its recommendation algorithm within seven days, with updates every four weeks and detailed developer notes.
The move was presented as a step towards transparency in how content and advertising are ranked and distributed on the platform.
Ethereum co-founder Vitalik Buterin welcomed the idea but said transparency must be verifiable rather than limited to published code.
If done properly, this is a very good move, but I hope it can be verifiable and replicable.
Vitalik Buterin said.
Buterin suggested delayed audits of anonymised likes and posts so users could verify whether content was boosted or suppressed.
He warned that frequent four-week updates could undermine accountability and suggested a longer timeline for meaningful transparency.
Critics argued users need proof of how algorithms evaluate reach, signals and visibility rather than access to complex source code.
Some community members proposed cryptographic proofs to allow users to audit feed outcomes without compromising usability.
Others called for simpler feed logic based on follows, engagement and timestamps instead of predictive models.
The debate highlights growing pressure on X to balance openness, trust and usability in algorithm-driven feeds.
At the time of reporting, Ethereum price was $3,107.68.
