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

BNB Chain is a smart contract platform for decentralized applications (a blockchain). BNB Chain was founded by Changpeng Zhao and launched in 2020.

BNB holders own and govern the protocol. They currently take a cut of the total transaction fees paid by users (revenue).

# BNB Chain Revenue Methodology

## 1. Overview

BSC revenue represents the total daily revenue generated by the Binance Smart Chain (BSC) ecosystem, combining two distinct revenue streams: fee burns from the BSC mainnet and gas fees from the OpBNB Layer 2 network. This metric captures revenue through permanent token burns (BSC) and transaction fees (OpBNB), providing a comprehensive view of the economic value generated by the BSC blockchain infrastructure.

## 2. Data sources

- **BSC blockchain events**: Parsed `ValidatorSet_feeBurned_event` events from BSC blockchain capturing fee burn transactions
- **OpBNB transaction data**: Raw transaction records from OpBNB Layer 2 network including gas usage, prices, and L1 fee parameters
- **Token metadata**: BNB and Wrapped BNB (WBNB) token information for proper decimal handling
- **End-of-day price feeds**: Daily closing prices for BNB token to enable USD conversion

## 3. Step-by-step calculation

### Component A: BSC fee burns
- **Purpose**: Captures revenue from permanently burned BNB tokens through the BSC validator fee burn mechanism
- **Logic**: Extracts `ValidatorSet_feeBurned_event` blockchain events from BSC, filtering specifically for events from the `BSCValidatorSet` account. Uses the hardcoded WBNB token address `0xbb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c` to identify relevant burn events. Aggregates the burned amounts daily by summing the `amount` field from all burn events within each day.
- **Key fields**: `block_timestamp` for daily grouping, `amount` for burn quantities, `account_address` filtered to `BSCValidatorSet`, `token_address` set to WBNB address

### Component B: OpBNB gas fees
- **Purpose**: Calculates total gas fees generated from OpBNB Layer 2 transactions, including both L1 and L2 components
- **Logic**: Processes raw OpBNB transaction data to calculate two fee components. L2 gas fees are calculated as gas used multiplied by gas price, divided by 1e18 for decimal normalization. L1 gas fees are calculated as L1 gas used multiplied by L1 gas price and L1 fee scalar, divided by 1e18. Both components are summed separately across all daily transactions, then combined as total gas fees.
- **Key fields**: `gas_used` and `gas_price` for L2 fees, `l1_gas_used`, `l1_gas_price`, and `l1_fee_scalar` for L1 fees, `token_address` set to OpBNB BNB address `0x4200000000000000000000000000000000000006`

### Final aggregation
- **Combining components**: BSC fee burns and OpBNB gas fees are combined through a union operation, with BSC tagged as `blockchains_l1` market sector and `bsc` product, while OpBNB is tagged as `blockchains_l2` market sector and `opbnb` product
- **Currency conversion**: All revenue amounts are converted to USD using end-of-day BNB token prices and corrected for proper decimal places through the standard conversion macro
- **Time aggregation**: Both components use daily timestamp truncation, ensuring all data is aggregated to daily boundaries
- **Final calculation**: The final revenue metric equals the sum of daily BSC fee burns plus daily OpBNB gas fees (L1 + L2 components), all converted to USD values
