Lucid’s reputation system transforms raw traffic data into verifiable trust scores. Unlike self-reported ratings, every reputation signal in Lucid is anchored to a cryptographic receipt from a real interaction.

​
Three-Layer Architecture

​
Layer 1: On-Chain (Solana)

The lucid_reputation program stores immutable reputation data:
  • Feedback entries — Score (1-100), category, receipt hash, asset type
  • Validation entries — Third-party verification that a receipt is valid
  • Passport stats — Rolling aggregates: feedback count, validation count, average score
  • Revocation — Original submitters can revoke feedback; scores adjust atomically
Average scores are stored with 2-decimal precision (value * 100) and recomputed on every submission or revocation.

​
Layer 2: Off-Chain (API)

The IReputationProvider interface aggregates data from multiple sources:
  • Database-backed provider for fast queries
  • On-chain provider for verified data
  • Multiple scoring algorithms via IReputationAlgorithm

​
Layer 3: Gateway (PayReputation)

Credit scoring derived from payment history through TrustGate:
TierDescription
UnverifiedNo payment history
BronzeBasic payment history
SilverConsistent payments
GoldHigh-volume verified payments
PlatinumExtensive verified history
Scores are cached for 5 minutes and recomputed from receipt_events.

​
Reputation Per Asset Type

Reputation applies to all five AI asset types:
Type IDAsset TypeWhat Is Measured
0ModelAccuracy, latency, consistency
1ComputeUptime, throughput, reliability
2ToolCorrectness, availability
3AgentTask completion, user satisfaction
4DatasetQuality, freshness, coverage

​
Submitting Feedback

Feedback requires a valid receipt hash, proving the submitter actually interacted with the asset: 
import { RaijinLabsLucidAi } from "raijin-labs-lucid-ai";

const sdk = new RaijinLabsLucidAi({
  serverURL: "https://api.lucid.foundation",
  security: { bearerAuth: process.env.LUCID_API_KEY },
});

await sdk.reputation.lucidComputeReputation({
  passportId: 'agent-abc123',
  assetType: 'agent',
});

​
Revoking Feedback

Only the original submitter can revoke. The on-chain program atomically adjusts the total and average scores. The feedback_count is never decremented (it tracks total entries ever created, used as PDA seed), but total_score and avg_score reflect only non-revoked entries.

​
Cross-Network Reputation

Lucid’s reputation system syncs with external identity standards:
StandardIntegration
Metaplex (MIP #52)Bidirectional sync via syncReputationPlugin() (prep code, awaiting MIP release)
8004 / SATI / SAIDConsume scores from external protocols and feed validated scores back
This creates a bidirectional reputation mesh: Lucid consumes external signals and feeds its own verified scores back into the broader ecosystem.
