Suspicion Score Adjustment

Suspicion Score Adjustment is a mechanism to reduce the influence of potentially colluding or sybil voters without requiring hard bans. It employs behavior and connection patterns to assign each participant a score between 0 and 1, where zero indicates full trust and one indicates complete suspicion.

Suspicion Score Formula

The calculation uses three weighted factors:

  • O(v) — overlap in voting clusters
  • S(v) — average scores of associated voters
  • R(v) — support of suspicious proposals

Three alpha weights sum to 1.

Vote Weight Adjustment

Two methods reduce effective votes:

W(v) = 1 - SS(v)

Or an exponential variant:

W(v) = e^(-beta × SS(v))

Decay Mechanism

Scores decay each round, allowing recovery through honest participation:

SS_new(v) = gamma × SS(v)

Benefits

  • Discourages sybil attacks and vote manipulation
  • Preserves voter privacy and inclusion
  • Aligns with gradual trust principles rather than binary judgments
