# Contribution Rewards Engine

The Aether token forms the economic foundation of the Aether distributed network and serves as theunit of reward for verified bandwidth contribution. The distribution model is designed to directly link the quality, stability, and utility of provided network resources to reward output, ensuring a transparent and demand-aligned incentive system for participants.

Each device generates rewards based on **Proof-of-Bandwidth Contribution (PoBC)** — a cryptographically verified report that reflects the actual volume of encrypted data transmitted, the quality of the communication channel, and the stability of node performance. Rewards are issued only after full validation across all verification stages, eliminating the possibility of traffic simulation, synthetic activity, or manipulated reporting.

The reward model is defined by the dynamic formula:

```
AET = BaseRate × DeliveredBytes × QualityFactor × StabilityIndex × DemandWeight
```

Where BaseRate defines the baseline cost per unit of verified traffic and is dynamically adjusted through on-chain governance mechanisms on **Solana** to maintain long-term economic stability and controlled emission behavior. DeliveredBytes represents the total volume of successfully verified transmissions after filtering invalid, corrupted, or incomplete packets through statistical validation layers.

QualityFactor reflects the suitability of a network path for institutional-grade traffic and is derived from metrics such as RTT stability, latency variance, jitter profile, retransmission rate, and routing efficiency. Higher-quality connections receive increased weighting due to their greater utility for demand-side applications.

StabilityIndex represents the temporal reliability of a node and measures consistency across extended operational periods. Nodes with frequent disconnects, unstable throughput, or inconsistent RBW behavior receive reduced weighting, while long-term stable contributors gain progressively higher reward efficiency.

DemandWeight is a real-time multiplier reflecting live infrastructure demand across different geographic regions. The system continuously adjusts this parameter based on network load distribution and institutional requirements, increasing rewards in under-supplied regions and reducing imbalance between supply and demand across the ecosystem.

Reward distribution does not occur continuously at the packet level. Instead, PoBC records are aggregated into batch intervals and submitted to the **Solana** blockchain at fixed time windows. After validation, smart contracts execute deterministic reward settlement by distributing tokens to nodes based on their verified contribution profiles. Only anonymized session-level hashes and aggregated metrics are recorded on-chain, ensuring that no personal or device-level data is ever exposed.

The system incorporates an anti-manipulation framework designed to detect anomalies in throughput behavior, RBW exploitation attempts, traffic simulation, and statistical inconsistencies in contribution patterns. Detection is based on multi-dimensional behavioral analysis, including temporal variance, packet distribution consistency, and correlation between predicted and observed bandwidth usage. Nodes identified as engaging in manipulation are excluded from reward eligibility for the affected settlement period.

Overall, the reward structure ensures that compensation is strictly proportional to verifiable network contribution, aligning economic incentives with real infrastructure demand. This creates a self-balancing system where participant rewards directly reflect the utility provided to the network while maintaining long-term stability and integrity of the Aether ecosystem.
