Pudgy Penguins
Strong trust signals with high statistical confidence. Large dataset (5,500 data points) provides high confidence. Floor Price Stability above average. Liquidity Depth above average.
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 |
|---|---|---|---|---|
| Floor Price Stability | 92.4% | ±7 | +5.94 | |
| Liquidity Depth | 86.0% | ±6 | +4.32 | |
| Holder Diversity | 61.9% | ±7 | +1.66 | |
| Team Transparency | 90.0% | ±4 | +3.20 | |
| Royalty Enforcement | 85.0% | ±4 | +2.80 | |
| Incident History | 100.0% | ±6 | +6.00 | |
| Historical Volume | 72.5% | ±4 | +1.80 |
Why this grade?
Strong trust signals with high statistical confidence. Large dataset (5,500 data points) provides high confidence. Floor Price Stability above average. Liquidity Depth above average.
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 7 weighted optional signals specific to nft collections.
