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

Sui is a smart contract platform for decentralized applications (a blockchain). Sui was founded by Evan Cheng, Sam Blackshear, Adeniyi Abiodun, George Danezis and launched in 2022.

Sui (Mysten Labs) team & investors own and govern the protocol. They currently don’t take a cut of the total transaction fees paid by users (revenue). Sui's investors include a16z, Coinbase Ventures, Electric Capital, etc.

# Sui Earnings Methodology

## 1. Overview

Earnings measures the net profitability of the Sui network. This metric is calculated by subtracting network expenses from protocol revenue. On Sui, revenue is recognized as the non-refundable portion of transaction fees, which are burned to accrue value to asset holders. Expenses are defined as the total value of staking rewards (token incentives) distributed to validators to secure the network.

## 2. Data sources

- **Blockchain events**: `SystemEpochInfoEvent` events from `SuiSystemStateInner` contracts and transaction gas data on Sui
- **External data**: End-of-day price feeds for the native SUI asset

## 3. Step-by-step calculation

### Component A: Protocol revenue (burned fees)
- **Purpose**: Determine the total value recognized as revenue from network activity.
- **Logic**: Transaction-level gas data is extracted from the ledger. Protocol revenue is calculated as the sum of the computation cost and 1% of the storage cost, representing the non-refundable portion of transaction fees. Refundable storage deposits and rebates are excluded as protocol liabilities. Because 100% of these non-refundable fees are burned, they are recognized as protocol revenue.
- **Key fields**: `computation_cost`, `storage_cost`

### Component B: Network expenses (token incentives)
- **Purpose**: Capture the cost of network security paid to validators.
- **Logic**: Staking rewards are parsed from `SystemEpochInfoEvent` events from `SuiSystemStateInner` contracts, which are emitted once per epoch. The `total_stake_rewards_distributed` field, representing the sum of stake subsidies and storage fund reinvestments, is extracted to calculate total network expenses.
- **Key fields**: `total_stake_rewards_distributed`

### Component C: USD conversion and final aggregation

- **Purpose**: Normalize values to USD and calculate the net earnings.
- **Logic**: All native SUI amounts are normalized by decimal precision. Values are multiplied by end-of-day price feeds to arrive at USD-denominated totals. Daily earnings are then calculated by subtracting recognized expenses from recognized revenue.
- **Key fields**: `earnings` (calculated as `revenue - expenses`)

Net profit (also profits, net income, profitability) — revenue remaining after subtracting expenses.
