# Ajuna Substrate Number of validators Methodology

## 1. Overview

Number of validators measures the number of active nodes that produce blocks and secure the network. It reflects the degree of decentralization and resilience of the blockchain. For Ajuna Substrate, this metric specifically identifies the active set of collators that participate in the network's consensus and block production process.

## 2. Data sources

- **Blockchain events**: `NewInvulnerables` and `InvulnerableRemoved` events from the `collatorSelection` pallet on Ajuna Substrate

## 3. Step-by-step calculation

### Component A: Collator set membership tracking

- **Purpose**: Identify the addition and removal of active validators from the network.
- **Logic**: `NewInvulnerables` and `InvulnerableRemoved` events are parsed from the `collatorSelection` pallet. The account addresses of collators are extracted from the event data. `NewInvulnerables` events are used to identify both the initial set of validators and any new validators added to the active pool, while `InvulnerableRemoved` events are used to identify validators that have exited the active set.
- **Key fields**: `event_method` (event type identification), `event_data` (validator account addresses).

### Component B: Validator count aggregation

- **Purpose**: Calculate the net change and total count of active validators.
- **Logic**: The number of distinct validator addresses from `NewInvulnerables` events is aggregated as a positive value, and the number of distinct addresses from `InvulnerableRemoved` events is aggregated as a negative value. These values are summed by day to determine the net change in the validator set.

### Component C: Cumulative total and temporal normalization

- **Purpose**: Generate a continuous time series of the total validator count.
- **Logic**: A running sum is applied to the daily net changes to calculate the total number of active validators for every day in the series. Because validator state changes may not occur daily, values are filled forward from the last known state to ensure a continuous daily record. Data is aggregated according to UTC day boundaries.
