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

Astar is a collective driving web3 adoption by connecting people through blockchain technology, business innovation, decentralized applications, and seamless digital experiences in the Polkadot ecosystem. Astar was founded by Sota Watanabe and launched in 2021.

ASTR tokenholders own and govern the protocol. Part of the transaction fees is burned (revenue). Astar’s investors include Binance, Polychain Capital, Crypto.com, etc.

# Astar Number of validators Methodology

## 1. Overview

The number of validators metric measures the daily count of unique validators actively participating in block production on the Astar blockchain. This metric provides insight into the decentralization and network security of the Astar network by tracking how many different validators are producing blocks each day. The calculation identifies unique block producers (validators) per day and maintains a continuous time series using forward-fill logic for days with missing data.

## 2. Data sources

- **Astar blockchain block data**: Raw block records from the Astar blockchain containing block metadata including timestamps, block numbers, and validator identifiers
- **Block production records**: Each block record includes the validator ID (`author_id`) of the validator who produced that specific block

## 3. Step-by-step calculation

### Component A: Daily validator identification
- **Purpose**: Identify and count unique validators producing blocks each day
- **Logic**: Raw Astar block data is processed to extract block timestamps and validator identifiers. Block timestamps are truncated to daily boundaries to group all blocks produced within the same calendar day. For each day, the system counts the number of distinct validator IDs (`author_id`) that produced at least one block during that day
- **Key fields**: `block_timestamp` (truncated to day), `author_id` (validator identifier), `number_of_validators` (distinct count)

### Final aggregation
- **Time aggregation**: Data is grouped by calendar day using timestamp truncation, ensuring all blocks from the same day are considered together
- **Validator counting**: The metric uses distinct counting logic to ensure each validator is counted only once per day, regardless of how many blocks they produced
- **Gap handling**: Forward-fill strategy is applied to maintain continuous time series data, carrying forward the last known validator count for days when no blocks were produced
- **Data quality**: Chain availability filters are applied to ensure only reliable data periods are included in the final metric
- **Final calculation**: The daily number of validators equals the count of distinct validator IDs that produced at least one block on that specific day
