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

Darwinia Network is a decentralized blockchain for cross-chain interoperability and decentralized finance infrastructure powered by Polkadot Relay chain.

RING holders own and govern the protocol. Darwinia Network’s investors include HashKey, Waterdrip Capital, SevenX Ventures, etc.

# Darwinia Network Expenses Methodology

## 1. Overview

The Darwinia expenses metric measures the daily operational costs incurred by the Darwinia protocol through staking reward distributions. This metric captures the protocol's spending on network security and validator incentives by tracking all staking payout events on the Darwinia blockchain. Expenses represent the cost of maintaining network security through token-based rewards paid to validators and delegators.

## 2. Data sources

- **Darwinia blockchain events**: Raw event logs from the Darwinia blockchain containing staking-related transactions and state changes
- **Staking payout events**: Parsed `darwiniaStaking.Payout` events that record when staking rewards are distributed to network participants  
- **External price data**: End-of-day price feeds from CoinGecko for the Darwinia Network Native Token (RING) to enable USD conversion
- **Chain configuration data**: Availability and configuration settings for data quality filtering

## 3. Step-by-step calculation

### Component A: Staking rewards extraction
- **Purpose**: Extract and parse raw staking reward payout events from the Darwinia blockchain
- **Logic**: Filter Darwinia blockchain events for entries where the event pallet is `darwiniaStaking` and the event method is `Payout`. Extract the payout amount from the event data array at position [1] and convert from JSON format to numeric. Apply decimal conversion by dividing by 1e18 to convert from wei units to standard token amounts. Include block timestamp and extrinsic ID for tracking and aggregation purposes.
- **Key fields**: `block_timestamp` for time-based aggregation, `extrinsic_id` for transaction tracking, `amount` representing the staking reward payout in RING tokens

### Component B: Daily aggregation and USD conversion  
- **Purpose**: Aggregate staking rewards by day and convert to USD values
- **Logic**: Truncate block timestamps to daily boundaries and group all staking payouts by day, chain, and product. Sum all staking reward amounts within each daily period to get total daily token incentives. Apply USD conversion using CoinGecko price feeds for the Darwinia Network Native Token, matching daily token amounts with corresponding end-of-day prices. Maintain dimensional attributes including timestamp grain, chain ID, and product ID for proper metric categorization.
- **Key fields**: `timestamp` truncated to daily boundaries, `timestamp_grain` set to 'day', `chain_id` as 'darwinia', `product_id` as 'darwiniachain', `token_incentives` representing daily staking reward totals in USD

### Component C: Token incentives standardization
- **Purpose**: Apply standardization and data quality processes to token incentives data
- **Logic**: Process the aggregated token incentives data through finalization procedures that standardize metric format and handle missing data points. Apply a fill-forward strategy to maintain continuity in the time series by carrying forward the last known value for any missing daily periods. Include chain availability filtering to ensure data quality and completeness based on configuration settings.
- **Key fields**: `token_incentives` as standardized daily USD amounts with gap-filling applied

### Final aggregation
- **Combining components**: Map the processed token incentives values directly to expenses, since staking rewards represent the protocol's operational costs for maintaining network security
- **Currency conversion**: USD conversion occurs at the daily aggregation stage using end-of-day CoinGecko price feeds for RING tokens
- **Time aggregation**: Daily boundaries are established by truncating blockchain event timestamps to day-level granularity  
- **Final calculation**: The final expenses metric equals the daily sum of all staking reward payouts converted to USD, representing the protocol's daily operational spending on network incentives
