Score Breakdown

How the TrustGrade algorithm computed this score.

Wilson Score Lower Bound

89.09%

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

Bayesian Posterior

91.53%

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

Incident Penalty

-2.0%

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

Volume Bonus

+7.50

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) 94.0% ±7 +6.58
Audit Coverage 97.0% ±8 +7.76
Exploit History 96.0% ±9 +8.64
Team Transparency 97.0% ±4 +3.88
Governance Decentralization 81.0% ±5 +4.05
Network Security 104.0% ±5 +5.20

Why this grade?

Exceptional trust profile for this blockchain_network. TrustGrade score 94/100 (Grade A).

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 generics.

✅ Exceptional: This entity scores in the top tier of the TrustGrade methodology, indicating strong trust signals across all measured dimensions.
