# Backhaul provider

#### Backhaul Provider — Reward Specification

Backhaul Providers supply upstream internet bandwidth to the Dabba Network.\
They enable hotspots to connect to the broader internet and support end-user data consumption.

Backhaul Providers earn DBT in exchange for providing reliable, high-throughput upstream connectivity.

### Role in the Network

A Backhaul Provider:

* Supplies upstream bandwidth to one or more hotspots
* Maintains uptime and service quality
* Supports traffic growth as broadband adoption increases
* Ensures stable latency and throughput

Without backhaul connectivity, hotspots cannot serve users.

### Eligibility Requirements

To qualify for rewards in epoch t, a Backhaul Provider must:

* Be registered and verified on-chain
* Provide active upstream connectivity during the epoch
* Meet minimum uptime and performance thresholds
* Submit validated bandwidth usage data
* Pass compliance checks

Providers failing validation for an epoch receive no rewards for that epoch.

Total Reward Per Epoch

#### Year 1:

$$
Reward\_{BH,i,t} = \frac{R\_t}{B\_t}
$$

#### Year 2+:

$$
Reward\_{BH,i,t} = \frac{UBI\_t}{B\_t} + P\_{BH,i,t}
$$

### Settlement Process

* Performance metrics are calculated off-chain each epoch
* Eligibility and scoring are validated
* Results are submitted on-chain
* DBT rewards are distributed at the start of the next epoch

All settlements emit logs for transparency and auditability.

### What Increases Earnings?

Backhaul Providers earn more when:

* Traffic volume increases
* Network adoption grows
* Reliability remains high
* Latency remains stable
* Uptime approaches 100%

As broadband usage grows, performance-based rewards increase proportionally.

### Why This Design?

Year 1 prioritizes onboarding and infrastructure availability.

Year 2 onward prioritizes real bandwidth contribution and reliability.

This ensures that:

* Early participation is incentivized
* Long-term rewards align with measurable network value
