# Robonomics Network Earnings Methodology

## 1. Overview

Robonomics Network earnings is measured as the net value retained by the protocol after subtracting all expenses from revenue. Daily asset incentives (expenses) are subtracted from daily fee revenue, with both components converted to USD using end-of-day price feeds. The metric is calculated for Robonomics Substrate.

## 2. Data sources

- **Blockchain events**: `TransactionFeePaid` events and `BlockReward` events from the `lighthouse` pallet, covering Robonomics Substrate
- **External data**: End-of-day price feeds for the native asset and asset metadata

## 3. Step-by-step calculation

### Component A: Fee collection

- **Purpose**: Total daily transaction fees collected by Robonomics Substrate are calculated.
- **Logic**: `TransactionFeePaid` events are extracted from blockchain event logs. Two monetary components are parsed from the event data: the base transaction amount and the tip amount. Both amounts are normalized by decimal precision. Daily aggregation is performed by summing the total fees (base amount plus tip) for each day, which are then converted to USD using end-of-day price feeds.
- **Key fields**: `amount` (base transaction fee), `tip` (additional fee), `block_timestamp` (timing)

### Component B: Staking rewards tracking

- **Purpose**: Total daily staking rewards distributed to validators are calculated.
- **Logic**: `BlockReward` events are extracted from the `lighthouse` pallet in blockchain event logs. The reward amount is parsed and normalized by decimal precision. Daily aggregation is performed by summing all block rewards distributed each day, which are then converted to USD using end-of-day price feeds.
- **Key fields**: `amount` (block reward amount), `block_timestamp` (timing)

### Component C: Revenue calculation

- **Purpose**: Protocol revenue is defined as total transaction fees collected.
- **Logic**: Aggregated daily fee data from Component A is utilized, with the fees field designated as revenue.
- **Key fields**: `revenue` (total daily fees in USD)

### Component D: Expenses calculation

- **Purpose**: Protocol expenses are defined as staking rewards paid to validators.
- **Logic**: Aggregated daily staking rewards from Component B are treated as operational expenses. The asset incentives are designated as expenses, representing the cost of maintaining network security through validator rewards.
- **Key fields**: `expenses` (total daily asset incentives in USD)

### Component E: Earnings calculation and aggregation

- **Purpose**: Net earnings are calculated and aggregated.
- **Logic**: Daily expenses are subtracted from daily revenue for each timestamp. Calculations are performed at daily granularity using timestamp truncation to day boundaries. The final earnings values are filtered to only include timestamps on or before September 24, 2026.
- **Key fields**: `earnings` (net profit in USD)

Net profit (also profits, net income, profitability) — revenue remaining after subtracting expenses.
