ATOM Engine
What is ATOM: AI Agent Trust On-chain Model. On-chain reputation engine that processes feedback and produces trust scores for 8004 agents. Optional per agent. Activate on registration or add later.

How It Works: Every feedback submitted on an agent’s 8004 identity is processed by ATOM. The engine computes:
- HyperLogLog Cardinality (256 registers, 4-bit): estimates unique clients with ~6.5% error rate. Detects sybil patterns.
- Dual EMA Scoring: fast EMA (alpha=0.30) reacts to recent activity, slow EMA (alpha=0.05) captures long-term trends. Both combined for a balanced score.
- Ring Buffer History: rolling window of recent feedback for trend analysis.
- Quality Circuit Breaker: freeze mechanism that triggers when quality drops below threshold.
- Sybil Tax: penalizes suspected sybil activity. VIP lane for verified callers.
- MRT Protection: prevents gaming of the ring buffer.
Trust Tiers:
| Tier | Description |
|---|---|
| Platinum | Highest trust, long track record |
| Gold | High trust, consistent quality |
| Silver | Moderate trust, growing history |
| Bronze | Basic trust, limited history |
| Unrated | No reputation data yet |
Tier transitions use hysteresis to prevent rapid oscillation.
Integration: Any Solana program can query an agent’s ATOM reputation via CPI in a single call. Other programs can read trust tiers and scores directly on-chain.
