# 4.2 Trine Scoring Model™ – Contribution Quantification

The Trine Scoring Model™ is ACP’s proprietary evaluation framework that assesses contribution quality across three dimensions:

* **PerfCore**: How intensively and effectively the node works (compute performance).<br>
* **TrustWave**: Accuracy of results and consistency in passing validations.<br>
* **FlowRate**: Operational reliability and uptime over extended periods.\ <br>

Rather than rely on pure computation quantity, ACP assigns weighted contribution scores:

**Daily Reward Formula**\
Base Pool × (0.5 × PerfCore + 0.3 × TrustWave + 0.2 × FlowRate)

| Metric    | Description                                 | Example Evaluation                            |
| --------- | ------------------------------------------- | --------------------------------------------- |
| PerfCore  | GPU speed, execution count, time efficiency | High scores for top-tier compute rates        |
| TrustWave | Output validity, verification pass rate     | Assessed via oracle logs and accuracy checks  |
| FlowRate  | Uptime, daily continuity, crash rates       | Extra points for uninterrupted 30-day service |

The model promotes fairness and sustainability by rewarding consistent and reliable contributors over raw power.

ACP plans to evolve this system through:

1. **Anti-Domination Balancing** – Prevents reward monopolization by ultra-high-end GPUs.<br>
2. **Group-Based Benchmarking** – Peers are evaluated within similar spec tiers (e.g., region, hardware).<br>
3. **Tiered Reward Multiplier System** – Contributors with high Trine scores may receive bonus coefficients in future updates.
