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

Heima is a specialized identity and data verification blockchain powered by Polkadot Relay chain.

HEI holders own and govern the protocol. Heima’s investors include LD Capital, Digital Renaissance, Signum Capital, and others.

# Heima Expenses Methodology

## 1. Overview

The Heima expenses metric represents the daily operational expenses incurred by the Heima protocol through staking rewards distributions. This metric captures the cost of incentivizing network participants through staking rewards, treating these token distributions as operational expenses. The calculation aggregates all staking rewards paid out by the protocol daily and converts them to USD values to provide a standardized measure of protocol expenses.

## 2. Data sources

- **Heima blockchain events**: Parsed event logs from the Heima parachain containing staking reward distribution records
- **Token price feeds**: End-of-day price feeds from CoinGecko for the Heima token (LIT) to enable USD conversion

## 3. Step-by-step calculation

### Component A: Staking rewards extraction
- **Purpose**: Extracts all staking reward events from the Heima blockchain to identify token distributions
- **Logic**: Filters Heima blockchain events for two specific staking reward types: `parachainStaking` pallet `Rewarded` events and `scoreStaking` pallet `RewardClaimed` events. These events represent different types of staking rewards distributed by the protocol. The raw token amounts are extracted from the event data array (specifically the second element) and converted from wei to LIT tokens by dividing by 1e18
- **Key fields**: `block_timestamp` for timing, `extrinsic_id` for transaction identification, and `amount` representing the reward amount in LIT tokens

### Component B: Daily aggregation and USD conversion
- **Purpose**: Aggregates staking rewards by day and converts to USD values
- **Logic**: Groups all staking reward amounts by day using timestamp truncation to daily boundaries. Sums all reward amounts within each day to get total daily staking rewards distributed. Applies USD conversion using end-of-day CoinGecko price feeds for the Heima token to convert LIT amounts to USD values
- **Key fields**: `timestamp` at daily granularity, `timestamp_grain` set to 'day', `chain_id` as 'heima', `product_id` as 'heimachain', and `token_incentives` representing the USD value of daily staking rewards

### Component C: Token incentives metric finalization
- **Purpose**: Applies metric finalization logic to create a complete time series
- **Logic**: Takes the daily USD-converted staking rewards and applies metric finalization using a fill-forward strategy for handling missing data points. This ensures continuous time series data by carrying forward the last known value when data is missing for specific days
- **Key fields**: Maintains all previous fields with finalized `token_incentives` values

### Final aggregation
- **Combining components**: The final expenses metric directly uses the token incentives values, conceptually treating staking rewards as operational expenses
- **Currency conversion**: All amounts are converted to USD using end-of-day CoinGecko price feeds for the Heima token
- **Time aggregation**: Data is aggregated at daily boundaries using timestamp truncation
- **Final calculation**: Staking rewards (token_incentives) are renamed to expenses to reflect the business logic that token distributions for staking rewards represent operational costs for the protocol. A fill_zeros strategy is applied during final metric processing to ensure zero values for periods with no staking activity
