TrustFingerprint
This section provides an overview of the Noderr Protocol's on-chain reputation system, TrustFingerprint.
What TrustFingerprint Is
TrustFingerprint is Noderr's on-chain reputation score (implemented in TrustFingerprint.sol). It quantifies an operator's or agent's track record into a single trust value that the protocol uses to gate node tiers, weight participation, and qualify operators for higher-responsibility roles.
The score is stored on-chain on a 0–10,000 scale and is displayed as a normalized 0–1 value (for example, a stored value of 7,000 is shown as 0.70).
Promotion Thresholds
A minimum TrustFingerprint is required to enter each node tier:
| Tier | Minimum TrustFingerprint |
|---|---|
| Validator | 0.60 |
| Guardian | 0.70 |
| Oracle | 0.80 |
Higher tiers carry additional requirements beyond the score: Guardian also requires governance approval and a node NFT, and Oracle also requires election (66% Oracle supermajority vote) and a node NFT.
How It Connects to the Protocol
- Tier-based voting power. Governance weight scales by node tier (Micro 1x / Validator 2x / Guardian 4x / Oracle 7x), so a stronger TrustFingerprint that unlocks higher tiers also increases governance influence.
- Agent reputation ladder. Noderr's agent-protocol backend uses a parallel reputation ladder (Unverified / Registered / Proven / Established / Core Contributor), with promotion thresholds at Proven 0.30, Established 0.55, and Core Contributor 0.70.
