Multichain
Poor trust profile for this bridge. TrustGrade score 16/100 (Grade F).
Score Breakdown
How the TrustGrade algorithm computed this score.
Wilson Score Lower Bound
95% confidence interval lower bound on positive outcome rate. Penalizes small samples automatically.
Bayesian Posterior
Beta(α,β) posterior mean with sceptical prior. Adjusts observed rate toward conservative estimate.
Incident Penalty
Compound penalty: 1−(1−s)². 10% incidents → 19% penalty. 30% → 51%.
Volume Bonus
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 |
|---|---|---|---|---|
| Bridge Security Score | 82.0% | ±7 | +4.48 | |
| Validator Set Size | 75.0% | ±8 | +4.00 | |
| Incident History | 80.0% | ±9 | +5.40 | |
| Team Transparency | 75.0% | ±4 | +2.00 | |
| Upgrade Mechanism | 78.0% | ±4 | +2.24 | |
| Exploit Severity | 10.0% | ±5 | -4.00 |
Why this grade?
Poor trust profile for this bridge. TrustGrade score 16/100 (Grade F).
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.
⚠️ Notable risk: This entity has an elevated incident penalty of 30.0%, which significantly impacts the final score.
