Rating System

The score impacts tiers, fees, and access to certain actions.

Key goals:

• Promote successful P2P interactions.
• Integrate social verification for trust.
• Motivate users to connect accounts and maintain high reputation.

See also: Tier System.

Inputs

Connected accounts (base score)

• Telegram only: base_score = 200
• Telegram + X: base_score = 300

Deal outcomes

• succ_deal: number of successfully closed deals
• unsucc_deal: number of unsuccessful deals

PoSFI multiplier (from Ethos)

posfi_rating is a multiplier derived from Ethos.

• No X linked: default Ethos level is Untrusted → posfi_rating = 0.7
• Higher Ethos levels increase the multiplier up to 2.0

X verification bonus

If X is linked, apply a one-time bonus:

• unsucc_deal = max(0, unsucc_deal - 1)

Score calculation

Use base_pts_per_deal = 10.

score = base_score
      + (succ_deal   × base_pts_per_deal × posfi_rating)
      − (unsucc_deal × base_pts_per_deal ÷ posfi_rating)

Where:

• base_score: 200 (Telegram only) or 300 (Telegram + X).
• succ_deal: Number of successfully closed deals.
• unsucc_deal: Number of unsuccessful deals.
• base_pts_per_deal: Fixed at 10 points per deal.
• posfi_rating: 0.7 to 2.0, based on Ethos level (see table below).

This formula rewards successful deals with a boost from posfi_rating while penalizing failures more harshly for low-reputation users (since division by low posfi_rating increases the deduction).

Worked examples

Example A (Telegram only, Neutral Ethos)

Assume:

• base_score = 200
• posfi_rating = 1.0
• succ_deal = 10
• unsucc_deal = 1

Result:

• score = 200 + (10 × 10 × 1.0) − (1 × 10 ÷ 1.0) = 290

Example B (Telegram + X, Established Ethos)

Assume:

• base_score = 300
• posfi_rating = 1.3
• succ_deal = 10
• unsucc_deal = 1
• X bonus: unsucc_deal = max(0, 1 − 1) = 0

Result:

• score = 300 + (10 × 10 × 1.3) − 0 = 430
