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

Mythos is a specialized gaming blockchain powered by Polkadot Relay chain.

MYTH holders own and govern the protocol.

# Mythos Expenses Methodology

## 1. Overview

The Mythos expenses metric measures the total USD value of token incentives paid out by the Mythos protocol to network participants. These expenses represent staking rewards distributed to collators (validators) on the Mythos blockchain. The metric captures the daily cost incurred by the protocol in maintaining network security through staking incentives, calculated by aggregating native MYTH token rewards and converting them to USD values.

## 2. Data sources

- **Mythos blockchain events**: Parsed event logs from the Mythos blockchain's `collatorStaking` pallet, specifically capturing `StakingRewardReceived` events that record when staking rewards are distributed to network validators
- **End-of-day price feeds**: Daily MYTH token prices from CoinGecko API for USD conversion
- **Chain availability data**: Configuration data that determines valid date ranges for metric calculation and reporting

## 3. Step-by-step calculation

### Component A: Raw staking rewards extraction
- **Purpose**: Extract and parse staking reward events from Mythos blockchain
- **Logic**: Filter Mythos blockchain events for `collatorStaking` pallet and `StakingRewardReceived` method. Parse the reward amount from the second element of the `event_data` JSON array. Convert amounts from Wei units (1e18) to native MYTH tokens by dividing by 10^18. Include `block_timestamp` and `extrinsic_id` for transaction tracking.
- **Key fields**: `block_timestamp` for timing, `event_data` array containing reward amounts, `amount` as the parsed MYTH token reward value

### Component B: Daily aggregation and USD conversion
- **Purpose**: Aggregate staking rewards by day and convert to USD values
- **Logic**: Truncate timestamps to daily boundaries using day-level granularity. Group by date, chain identifier ('mythos'), and product identifier ('Mythos Substrate'). Sum all staking reward amounts for each day. Apply USD conversion using end-of-day CoinGecko price feeds for the MYTH token, matching daily timestamps to corresponding price data.
- **Key fields**: `timestamp` as daily boundary, `chain_id` as 'mythos', `product_id` as 'Mythos Substrate', `token_incentives` as daily USD-converted reward totals

### Component C: Token incentives metric finalization
- **Purpose**: Standardize the token incentives data into proper metric format
- **Logic**: Apply metric finalization logic to ensure consistent data structure and completeness. Use zero-fill strategy to populate missing days with zero values, maintaining continuous time series. Apply chain availability filters to exclude dates outside valid reporting periods.
- **Key fields**: Standardized `timestamp`, `timestamp_grain`, `chain_id`, `product_id`, and `token_incentives` fields

### Final aggregation
- **Combining components**: Map the `token_incentives` field directly to the `expenses` field, as staking rewards represent the protocol's operational expenses for network security
- **Currency conversion**: USD conversion occurs at the daily aggregation stage using end-of-day MYTH token prices from CoinGecko
- **Time aggregation**: Daily boundaries are established by truncating timestamps to day level, with all staking rewards within a 24-hour period summed together
- **Final calculation**: The final expenses value equals the total USD value of staking rewards paid out each day, with zero-filling applied to ensure complete time series coverage and chain availability filters ensuring data quality
