On April 24, 2025, Ethos launched an experiment with anonymous reviews. Anyone could submit a review through a form without attaching their name, and the review would be stored onchain through @kairosAgent.

On Ethos, people review and vouch for each other, and every account gets a credibility score from what others say about it. Reviews are normally tied to the person who writes them. This experiment tested what happens when someone wants to share what they know without putting their own account behind it.

Why Ethos ran the experiment

Ethos framed the launch as part of a broader commitment to experimentation in order to build the best possible product. Anonymous reviews were offered as a test, not a permanent feature.

How the process worked

Ethos described the idea as simple, with three steps:

• Users filled out an anonymous Google form, which Ethos said tracked zero personal information
• The Ethos team reviewed the submissions
• The Ethos team posted them as @kairosAgent

The form was available at forms.gle/1isJs4NBr4rz6ZgB9. Because the reviews were published from the @kairosAgent account, they were stored onchain like any other Ethos review, but without linking back to the person who wrote them.

Keeping the impact small

Anonymous input carries an obvious risk: without a name attached, there is less accountability for what is said. Ethos addressed this through the account that posted the reviews.

According to Ethos, @kairosAgent had a low credibility score, so anonymous reviews posted from it would have only a minimal effect on the credibility of the accounts being reviewed. In other words, the reviews could put information on the record without carrying the same weight as a review from a well-established account.

That design reflects how Ethos works more generally. A review’s influence depends in part on the credibility of whoever leaves it, so routing anonymous reviews through a low-credibility account kept them visible while limiting how much they could move someone’s score.

What the posts don’t say

The posts announced the experiment and explained its setup. They don’t record how long it ran, how many reviews were submitted or what Ethos concluded from it.
