# Robonomics Substrate Expenses Methodology

## 1. Overview

Expenses measures the total cost incurred by Robonomics Substrate to maintain its decentralized infrastructure and secure its operations. This metric specifically captures token incentives distributed to lighthouse providers and other network participants. These distributions are issued as block rewards to compensate for the computational resources and connectivity required to facilitate autonomous robot-to-cloud communications.

## 2. Data sources

- **Blockchain events**: `BlockReward` events from `lighthouse` pallet contracts on Robonomics Substrate
- **External data**: End-of-day price feeds for the native Robonomics Network asset

## 3. Step-by-step calculation

### Component A: Token incentive extraction

- **Purpose**: Captures the quantity of native assets issued by the protocol as staking rewards and infrastructure incentives
- **Logic**: `BlockReward` events are parsed from the `lighthouse` pallet. The reward amount is extracted from the event data payload.
- **Key fields**: `event_data` (containing reward quantities), `event_method` (filtered for block rewards), `event_pallet` (filtered for lighthouse modules)

### Component B: USD conversion and aggregation

- **Purpose**: Normalizes the captured incentive data into a standard currency for reporting
- **Logic**: Extracted reward amounts are normalized by decimal precision. These values are then multiplied by end-of-day price feeds for the Robonomics Network asset. Data is aggregated to a daily grain using UTC day boundaries.

### Component C: Final expense classification

- **Purpose**: Maps the processed incentive data to the Expenses metric
- **Logic**: The total value of token incentives calculated in Component B is assigned to the Expenses metric for Robonomics Substrate. This reflects the protocol's primary operating cost associated with network security and service delivery. Missing data points are zero-filled to ensure a continuous time series.
