# Polkadot Relay Chain Transaction count Methodology

## 1. Overview

Transaction count measures the number of confirmed transactions added to Polkadot Relay Chain. It reflects how actively users engage with the network. In the Polkadot ecosystem, these transactions are processed as extrinsics, which represent external data points processed by the relay chain's validator set to update the state of the network.

## 2. Data sources

- **Blockchain events**: Confirmed extrinsics from Polkadot Relay Chain, Polkadot AssetHub, Polkadot Collectives, Polkadot BridgeHub, and 2 other chains

## 3. Step-by-step calculation

### Component A: Extrinsic data extraction

- **Purpose**: Retrieve and standardize raw transaction data from the Polkadot Relay Chain.
- **Logic**: Records are extracted from the underlying extrinsics records for Polkadot Relay Chain. Data fields including the block timestamp, transaction hash, and unique transaction index are selected and cast to standardized formats. A product identifier is assigned to distinguish these records from other parachain data within the Polkadot ecosystem.
- **Key fields**: `block_timestamp`, `transaction_hash`, and `transaction_index`.

### Component B: Transaction count aggregation

- **Purpose**: Calculate the daily volume of unique transactions.
- **Logic**: The total number of unique transaction indices is calculated for each 24-hour period. Data is aggregated based on UTC day boundaries. The resulting counts are filtered to ensure only validated records from Polkadot Relay Chain are included. A zero-filling strategy is applied to any timestamps where no activity is recorded to ensure a continuous data series.

Transaction count

Blockchains (L1)

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

Polkadot is a security & interoperability platform for blockchains and applications. Polkadot was founded by Gavin Wood and launched in 2020.

DOT holders own and govern the protocol. They currently take a cut of the total transaction fees paid by users (revenue). Polkadot’s investors include Polychain, IOSG Ventures, Hashkey, etc.
