Core Borealis Concept
BM Score (Borealis Trust Score)
The Borealis Trust Score. A 0-1000 rating (displayed as 0-100) measuring AI agent trustworthiness across five weighted behavioral dimensions, anchored to Hedera Hashgraph as immutable proof.
Explanation
The BM Score is computed across five dimensions: Constraint Adherence (35%), Decision Transparency (20%), Behavioral Consistency (20%), Anomaly Rate (15%), Audit Completeness (10%). The raw score out of 1000 is divided by 10 for display. Credit ratings (AAA+ through Flagged) are assigned at fixed thresholds: AAA+ starts at 980/1000.
Why it matters
A single trustworthiness number creates the market signal needed for trust-based commerce. Like a credit score in finance or a safety rating in automotive, the BM Score lets buyers and regulators evaluate AI agents without running their own audits.
How Borealis uses it
BM Scores are public via /v1/verify/:agentId and /v1/agents/public. Scores update with each completed audit or telemetry batch. The score drives tier classification, marketplace access on Borealis Terminal, and Trust Badge eligibility.
