Lucid’s reputation system builds trust scores for AI assets from real traffic data. Unlike self-reported metrics, Lucid reputation is backed by cryptographic receipts — every score is traceable to verified interactions.

​
Architecture

Reputation operates across three layers:
LayerComponentPurpose
On-chainlucid_reputation Solana programImmutable feedback, validation, revocation
Off-chainIReputationProviderAggregation algorithms, scoring, caching
GatewayPayReputationCredit scoring from payment history

​
How Scores Are Computed

Reputation scores combine multiple signals:
  1. Feedback — Users submit scores (1-100) per interaction, linked to a receipt hash
  2. Validation — Third parties validate receipts, confirming interactions occurred
  3. Revocation — Submitters can revoke feedback; the score adjusts atomically
  4. Traffic volume — More verified interactions increase confidence
  5. Payment history — Consistent payments improve credit tier
The on-chain program maintains rolling statistics per passport: feedback count, validation count, total score, and average score (stored with 2-decimal precision).

​
Submitting Feedback

curl -X POST https://api.lucid.foundation/v1/reputation/feedback \
  -H "Authorization: Bearer lk_..." \
  -d '{
    "passportId": "agent-abc123",
    "score": 85,
    "category": "accuracy",
    "receiptHash": "0xabc..."
  }'
Feedback requires a valid receipt hash, ensuring that only users who actually interacted with the asset can rate it.

​
Reputation Tiers (PayReputation)

At the gateway level, agents accumulate a credit tier based on payment history:
TierRequirements
UnverifiedNo payment history
BronzeBasic payment history
SilverConsistent payment record
GoldHigh-volume verified payments
PlatinumExtensive verified history
Higher tiers unlock benefits like reduced payment verification overhead and higher trust in multi-agent delegation.

Querying Reputation

# Get reputation for an agent
curl https://api.lucid.foundation/v1/reputation/agent-abc123 \
  -H "Authorization: Bearer lk_..."

# Via the control plane (admin)
curl https://control-plane.lucid.foundation/admin/reputation/agent-abc123 \
  -H "X-Admin-Key: ..."

Cross-Network Sync

Lucid reputation syncs with external identity standards:

Lucid extends Metaplex identity beyond agents to all AI assets (models, compute, tools, datasets), creating a bidirectional reputation mesh.
