Summary

Introduce a new reputation-score element: "Reputation boost for existing social graphs"

For every non-Ethos user we count how many "Reputable"-tier (or higher) Ethos profiles follow them on connected social networks and allocate up to +400 points on a percentile basis.

Impact

External accounts with strong reputable followership gain an initial credibility boost, better reflecting their existing credibility.

Motivation

• Improve Ethos score evaluation for users still outside the platform.
• Provide a bootstrap path for newcomers who are already widely recognized.

Specification

1. Definitions

   • Reputable User – any Ethos profile with score higher than 1600.
   • External Account – a social-network identity or wallet address without an Ethos profile.
   • Reputable Follower Count (RFC) – number of distinct Reputable Users following the External Account

2. Score Calculation

   a. Identify all External Accounts with RFC > 0. b. Compute the percentile rank of each External Account by number of followers. c. Assign a sigmoid calculation to the percentile rank, stretching the 0-100 range to a 0-400 range.

3. Dynamic Population Updates

   • Percentiles are recomputed regularly. This implies that a change in the user's percentile rank will change the score contribution, even if the user's individual RFC did not change.

4. Decay on Ethos-Profile Creation

   • When an External Account is claimed and becomes an Ethos profile, its stored Reputable Followers Impact begins a linear decay from its current value to 0 over the next 60 days.
   • After the decay period the factor is permanently 0; the user's score is then governed entirely by standard Ethos mechanisms.

5. Caps & Interaction

   • Max +400 pts; no negative values.
   • The global 2800-point cap remains unchanged. Because non-Ethos profiles cannot have reputation markets, that range can safely overlap this one.

Rationale

• Percentile scaling normalizes follower-count variability.
• Decay clause prevents double-counting: once a user is on Ethos, their credibility should stem from on-platform activity, not indefinitely from external follows.

Considerations & Safeguards

• Sybil resistance: acquiring Reputable status is costly, limiting fake-follower farms.

Future considerations

• Today this EIP covers only adding reputation. In the future we could use this as a basis for determining when there is a significant mismatch between reputation and existing social graph presence and potentially remove score in the event someone has a very high Ethos reputation score with very low.
  • Example: User A is in top 1% of all Ethos scores (i.e. 2400), but bottom 10% of reputable followers (i.e. 4 followers) could eventually penalize users one day.
• This EIP also is only for users who are NOT on Ethos, we could eventually also extend this to users with profiles too.
