On-Chain Reputation

Deterministic trust scores derived from channel history.

AMP includes a reputation system derived from channel history. Scores are computed on-chain from verifiable settlement data — no external oracle, no subjective rating.

Score calculation

base_score = (channels_completed / channels_opened) * 5000
volume_bonus = min(log2(total_volume / 1_000_000) * 500, 2500)
streak_bonus = min(current_streak * 50, 1500)
dispute_penalty = dispute_count * 500
 
score = clamp(base_score + volume_bonus + streak_bonus - dispute_penalty, 0, 10000)

Score range: 0 to 10,000. Higher is better.

Reputation-based pricing

Services can offer tiered pricing based on agent reputation:

{
  "pricing": {
    "default": { "mode": "per-call", "rate": "10000" },
    "reputation_tiers": [
      { "min_score": 5000, "rate": "8000" },
      { "min_score": 8000, "rate": "5000" },
      { "min_score": 9500, "rate": "3000" }
    ]
  }
}

Higher reputation = lower prices. Incentivizes good behavior.

How scores update

Event	Effect
`open_channel`	Increment `total_channels_opened`
`settle`	Increment `total_settlements`, extend streak
`close_channel` (clean)	Increment `total_channels_completed`
`close_channel` (dispute)	Increment `dispute_count`, reset streak
