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 Number of validators Methodology

## 1. Overview

Number of validators measures the count of active nodes that participate in the Sui consensus process to produce blocks and secure the network. This metric reflects the degree of decentralization and the structural resilience of the blockchain. Active validators are responsible for verifying transactions and maintaining the state of the network during each epoch.

## 2. Data sources

- **Blockchain events**: `ValidatorEpochInfoEventV2` events from system contracts on Sui
- **External data**: None

## 3. Step-by-step calculation

### Component A: Validator event extraction

- **Purpose**: Identify the set of active validators participating in the network at each epoch boundary.
- **Logic**: `ValidatorEpochInfoEventV2` events are parsed from the system event logs. Each event record corresponds to a single active validator for a given epoch. The total count of these events within a specific timestamp reflects the size of the validator set for that period.

### Component B: Daily aggregation and averaging

- **Purpose**: Normalize epoch-based validator counts into a daily time series.
- **Logic**: The number of validators is aggregated based on the block timestamp of the epoch events. For days containing multiple epoch transitions, the daily value is calculated by taking the average of the validator counts recorded. All timestamps are truncated to daily granularity using UTC boundaries.

### Component C: Data continuity and finalization

- **Purpose**: Ensure a consistent and continuous data series for institutional reporting.
- **Logic**: A fill-forward strategy is applied to the time series to account for any periods where new epoch events are not explicitly recorded. This ensures the most recent known validator count is maintained until a new update is processed. The resulting values are then mapped to canonical chain identifiers.
