// attributes & scoring
Every service starts from two base scores of 50 — Privacy and Trust. The attributes in the catalog below add or subtract points (each axis capped 0–100). The headline grade is a weighted blend:
Overall = Privacy × 60% + Trust × 40%
Most attributes are set once by a moderator. Some are derived automatically from data we already have (marked auto) and update on their own over time — service age, Monero support, live-rate integration, our verification window. Nothing is a hand-tuned number: change a rule and every service recalculates.
A confirmed incident applies a one-time trust penalty that fades to zero over a window set by severity. The resolution outcome immediately shrinks the penalty, then the remainder decays.
| Severity | Penalty | Decays over |
|---|---|---|
| Low | −5 | 90 days |
| Medium | −12 | 180 days |
| High | −22 | 365 days |
| Critical | −35 | 540 days |
Penalty retained by outcome: funds recovered 20% · users reimbursed 30% · partial recovery 50% · funds lost 75% · unknown 50%.
