Validators process transactions and receive fees from users (supply-side fees). DA costs for users are reflected in the transactions fees paid.

Celestia is a proof of stake blockchain optimized for data availability (DA). Celestia was founded by Mustafa Al-Bassam, etc. and launched in 2023.

TIA holders own and govern the protocol. They currently do not take a cut of the total transaction fees paid by users (revenue). Celestia's investors include Polychain Capital, Placeholder, Coinbase Ventures, etc.

# Celestia Fees Methodology

## 1. Overview

This metric calculates the total daily fees paid by users on the Celestia blockchain. It represents the sum of all transaction fees and tips paid to validators for processing transactions, converted to USD. This metric answers the business question: "How much are users paying in total to use the Celestia network each day?" The calculation aggregates individual transaction fees from all successful transactions, converts them from the native TIA token to USD, and presents them as daily totals.

## 2. Data sources

The calculation uses the following raw data sources:
- **Celestia transaction records**: Raw blockchain transaction data containing fee and tip information for all transactions processed on the Celestia network
- **CoinGecko price feeds**: End-of-day price feeds for the TIA token to enable USD conversion
- **Chain availability configuration**: Metadata defining when Celestia blockchain data is considered reliable and complete

## 3. Step-by-step calculation

### Component A: Transaction fee extraction
- **Purpose**: Extracts and normalizes transaction fees from raw Celestia blockchain data
- **Logic**: Retrieves all transaction records from the Celestia blockchain, focusing on the `transaction_fee` and `transaction_tip` fields. Both fee components are converted from their native microTIA format (divided by 10^6) to standard TIA token amounts, then combined into a single total transaction fee. Failed transactions with null fee values are excluded to ensure only successful, fee-paying transactions are counted.
- **Key fields**: `block_timestamp` for timing, `transaction_hash` for transaction identification, `transaction_fee` and `transaction_tip` for fee amounts

### Component B: Daily fee aggregation  
- **Purpose**: Groups transaction fees by day and aggregates them into daily totals
- **Logic**: Transaction timestamps are truncated to daily boundaries using the `block_timestamp` field. All transaction fees within each day are summed together to create daily fee totals. The data is enriched with chain identifier (`celestia`) and token identifier (`celestia` for CoinGecko price lookup) to support downstream processing.
- **Key fields**: `timestamp` (daily boundaries), `chain_id` (celestia), `coingecko_id` (celestia), `fees` (aggregated daily total in TIA)

### Final aggregation
- **Combining components**: The daily TIA fee totals flow directly from the aggregation component to the final metric calculation
- **Currency conversion**: TIA amounts are converted to USD using end-of-day CoinGecko price feeds for the TIA token, applying the conversion at the daily aggregation level
- **Time aggregation**: Data is aggregated at daily boundaries, with timestamps truncated to the start of each day
- **Final calculation**: The final metric value represents the total USD value of all transaction fees paid on Celestia for each day, calculated as the sum of all individual transaction fees (fee + tip) multiplied by the end-of-day TIA/USD exchange rate, with zero-filling applied for days with no transactions and chain availability filtering to ensure data quality
