Validators process transactions and receive fees from users (supply-side fees).

Ethereum is a smart contract platform for decentralized applications (a blockchain). Ethereum was founded by Vitalik Buterin, Anthony Di Iorio, Mihai Alisie, etc. and launched in 2015.

ETH holders own and govern the protocol. They currently take a cut of the total transaction fees (base fee) paid by users (revenue). Ethereum’s investors include KR1, Block Ventures, 8 Decimal Capital, etc.

# Ethereum Token incentives Methodology

## 1. Overview

The Ethereum token incentives metric measures the total daily token rewards issued by the Ethereum network to validators and miners. This metric captures the economic incentives paid out to secure the network, including both historical proof-of-work rewards (block, uncle, and nephew rewards) and current proof-of-stake rewards (beacon chain rewards). The calculation combines hardcoded historical reward schedules with real-time validator data to provide a comprehensive view of Ethereum's token issuance for network security.

## 2. Data sources

The metric relies on several key data sources:
- **Ethereum block data**: Raw blockchain block information including block numbers, timestamps, gas usage, and uncle block references
- **Uncle block data**: Details of uncle blocks including their relationships to main chain blocks, used for calculating uncle and nephew rewards
- **Beacon chain validator data**: Ethereum 2.0 validator statistics including validator counts, effective balances, and slot timestamps from the consensus layer
- **End-of-day price feeds**: ETH to USD conversion rates for currency normalization
- **Token metadata**: Decimal precision information for the WETH token used as the reward denomination

## 3. Step-by-step calculation

### Component A: Block rewards calculation
- **Purpose**: Calculate the base mining rewards paid to block producers under proof-of-work consensus
- **Logic**: Apply hardcoded reward amounts based on historical Ethereum network upgrades. Rewards are 5 ETH for blocks before Byzantium upgrade (block 4,370,000), 3 ETH between Byzantium and Constantinople (block 7,280,000), 2 ETH between Constantinople and The Merge (block 15,537,392), and 0 ETH after The Merge when proof-of-work ended. Each block reward is associated with the WETH token address and timestamped to the block's timestamp
- **Key fields**: `block_number` determines the reward amount, `block_timestamp` provides timing, `amount` contains the ETH reward value

### Component B: Uncle rewards calculation  
- **Purpose**: Calculate rewards paid to miners who found valid blocks that became uncles (orphaned blocks) in the proof-of-work system
- **Logic**: For each uncle block, calculate rewards using the formula: (uncle_block_number + 8 - main_block_number) × base_reward ÷ 8, where base_reward follows the same schedule as block rewards. This formula compensates uncle miners based on how close their block was to the main chain. Uncle rewards are set to 0 after The Merge
- **Key fields**: `uncle_block_number` and `block_number` determine the reward calculation, `amount` stores the calculated uncle reward

### Component C: Nephew rewards calculation
- **Purpose**: Calculate additional rewards paid to main chain miners for including uncle blocks in their blocks
- **Logic**: Calculate nephew rewards as 1/32 of the base block reward multiplied by the number of uncle blocks included (maximum of 2 uncles per block). This incentivized miners to include uncle blocks to strengthen network security. Nephew rewards are 0 after The Merge
- **Key fields**: `uncles` array length determines multiplier, `amount` from block rewards provides the base calculation

### Component D: Beacon chain rewards calculation
- **Purpose**: Calculate daily proof-of-stake rewards issued to validators on the Ethereum beacon chain
- **Logic**: Use validator data to calculate theoretical maximum daily issuance using the formula: 225 epochs per day × (32 ETH effective balance increment × 64 base reward factor × number of active validators) ÷ square root of total effective balance. The calculation uses the most recent validator data for each day by applying row numbering to deduplicate entries and select the final daily snapshot
- **Key fields**: `number_of_validators` provides the validator count, `total_effective_balance` represents total staked ETH, `amount` contains the calculated daily beacon rewards

### Final aggregation
- **Combining components**: All four reward components are unioned together into a single dataset with standardized fields including timestamp truncated to daily boundaries, reward type labels, and chain identifiers
- **Currency conversion**: ETH rewards are converted to USD using end-of-day price feeds, with decimal corrections applied to ensure proper token denomination
- **Time aggregation**: All rewards are aggregated to daily totals using timestamp truncation to day boundaries
- **Final calculation**: The final metric represents the sum of all daily token incentives across block rewards, uncle rewards, nephew rewards, and beacon chain rewards, converted to USD and validated for data completeness with gap-filling logic applied where necessary
