Score Breakdown

How the TrustGrade algorithm computed this score.

Wilson Score Lower Bound

73.15%

95% confidence interval lower bound on positive outcome rate. Penalizes small samples automatically.

Bayesian Posterior

79.85%

Beta(α,β) posterior mean with sceptical prior. Adjusts observed rate toward conservative estimate.

Incident Penalty

-5.0%

Compound penalty: 1−(1−s)². 10% incidents → 19% penalty. 30% → 51%.

Volume Bonus

+4.00

Log-credibility bonus: log₁₀(n)×k. More data = more confidence, diminishing returns.

Signal Contributions

Each signal's contribution to the final score. Positive = trust-building. Negative = risk-indicating.

Signal Value Weight Contribution Visualization
TVL Stability (30-day) 71.0% ±7 +4.97
Audit Coverage 77.0% ±8 +6.16
Exploit History 89.0% ±9 +8.01
Capital Adequacy 74.0% ±7 +5.18
Claims Processing 74.0% ±5 +3.70
Team Transparency 82.0% ±4 +3.28

Why this grade?

Good trust profile for this insurance_protocol. TrustGrade score 76/100 (Grade B).

The TrustGrade algorithm combines the Wilson score lower bound (which requires substantial evidence to score high), a Bayesian posterior (which shrinks toward a conservative estimate when sample sizes are small), a compound incident penalty (which grows faster than linear), a log-credibility volume bonus, and 6 weighted optional signals specific to defi protocols.
