Collators aggregate parachain transactions block candidates and producing state transition proofs for validators based on those blocks.

NeuroWeb is a decentralized Artificial Intelligence blockchain powered by Polkadot Relay chain.

NEURO holders own and govern the protocol.

# NeuroWeb Expenses Methodology

## 1. Overview

Expenses measures the daily USD value of block rewards issued by the NeuroWeb blockchain protocol. This is represented by the protocol's operational expense in the form of native asset emissions paid to validators and block producers for securing the network. `Issued` events from the `balances` pallet, which represent newly minted assets distributed as block rewards, are captured.

## 2. Data sources

- **Blockchain events**: `Issued` events from the `balances` pallet, covering NeuroWeb
- **External data**: End-of-day price feeds for the `neurowebai` asset

## 3. Step-by-step calculation

### Component A: Block reward event extraction

- **Purpose**: Identifies and extracts all block reward emission events from the NeuroWeb blockchain
- **Logic**: Raw NeuroWeb event logs are filtered to only include `Issued` events from the `balances` pallet, which represent newly minted assets issued as block rewards. The reward amount is extracted from the first element of the `event_data` JSON array and cast to a numeric value.
- **Key fields**: `timestamp`, `block_number`, `event_index`, `amount`

### Component B: Daily reward aggregation

- **Purpose**: Aggregates individual block rewards into daily totals and normalizes units
- **Logic**: All block reward events are grouped by day using timestamp truncation to day boundaries. Reward amounts are summed and normalized by decimal precision. Each daily record is tagged with metadata including chain identifier, market sector, and reward type classification.
- **Key fields**: `daily_timestamp`, `token_incentives`, `chain_id`, `reward_type`

### Component C: USD conversion

- **Purpose**: Converts daily asset amounts to USD values using market prices
- **Logic**: The `convert_to_usd_cg` macro is used to join daily amounts with end-of-day price feeds for the `neurowebai` asset. The USD price is applied to the asset amount to calculate the USD value of daily block rewards.
- **Key fields**: `token_incentives`, `asset_id`

### Component D: Final aggregation and metric classification

- **Purpose**: Finalize the expenses metric for reporting
- **Logic**: The USD-converted daily incentives flow directly into the expenses calculation. Data is aggregated to daily boundaries by truncating block timestamps to the day level. The final metric is renamed from `token_incentives` to `expenses` to reflect that these emissions represent operational costs for the protocol.
- **Key fields**: `token_incentives`, `expenses`
