Introducing EIP-2: Community Moderation for Review Impact
We’re rolling out EIP-2, a major upgrade to how reviews influence credibility scores on Ethos. This proposal brings the community directly into the loop, letting votes on a review shape how much it actually moves someone’s score.
In short: reviews that the community supports will carry more weight, and ones that get a lot of pushback will matter less (or not at all).
Why This Matters
Until now, a review’s impact was based mostly on two things:
- The reviewer’s own credibility (via our ELO-style ranking)
- The sentiment of the review (positive, negative, or neutral)
But there’s been no way for the broader community to weigh in on whether a review is fair or accurate, and that’s a problem. A single high-ELO user could write a low-quality or biased review, and it would still carry heavy weight.
EIP-2 solves that by introducing community sentiment weighting.
How It Works
We’re adding a new layer to the Review Impact algorithm: Community Sentiment Adjustment.
Every review can now be upvoted or downvoted by the community. Based on the pattern of votes, a review’s influence on credibility scores will adjust in real-time:
- Well-regarded reviews (more upvotes than downvotes) keep their full impact
- Heavily downvoted reviews (e.g., 5+ net downvotes) are effectively nullified; they no longer influence the score
- Slightly or moderately downvoted reviews have their impact reduced in proportion to the number of downvotes
This means that reviews need community alignment to make a real impact.
Why This Approach?
We designed it to be nuanced and fair:
- It’s flexible: Not every disagreement is treated the same. One downvote won’t kill a review, but five or more sends a stronger signal.
- It’s resilient: A review still has value unless there’s clear consensus against it.
- It keeps signal intact: If a review isn’t hotly contested, it still contributes, even if only slightly.
- It balances top-down and bottom-up inputs: Both the reviewer’s credibility and the community’s reaction matter.
What This Means for You
- The community has more power: You can now directly moderate which reviews matter most.
- Scores will be more accurate: Low-effort or unfair reviews won’t skew reputations as easily.
- No more needing admin appeals: This system reduces the need for centralized moderation. If you see a bad review, just downvote it.
- Future-proofing for Sybil resistance: While this system is live now, we’re already thinking about future updates to prevent coordinated vote manipulation or Sybil attacks.
Final Thoughts
EIP-2 is another step toward a more transparent, resilient, and community-governed credibility system.
