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 Token incentives Methodology

## 1. Overview

Token incentives measures the total value of native SUI assets distributed to network participants, primarily validators and stakers. These distributions serve to compensate supply-side stakeholders for providing network security and maintaining the blockchain infrastructure. The metric captures the inflationary cost of network operations and is analogous to stock-based compensation in traditional finance.

## 2. Data sources

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

## 3. Step-by-step calculation

### Component A: Staking reward extraction

- **Purpose**: Captures the value of SUI assets distributed to validators and stakers each epoch
- **Logic**: `SystemEpochInfoEvent` events are parsed from `sui_system_state_inner` contracts, which are emitted once per epoch (approximately daily). The `total_stake_rewards_distributed` field is extracted from the event data, representing the sum of the network stake subsidy and storage fund reinvestment. This value reflects the total compensation paid to validators for network security.
- **Key fields**: `total_stake_rewards_distributed` (distributed amount), `block_timestamp` (timing)

### Component B: Aggregation and USD conversion

- **Purpose**: Normalize reward values to USD and ensure a continuous daily time series
- **Logic**: Rewards are aggregated by day based on UTC boundaries. Extracted amounts are normalized by decimal precision and multiplied by end-of-day price feeds to determine the USD value. A zero-filling strategy is applied to the final dataset to ensure continuity across all historical dates.
