# Active users (monthly) Methodology

## 1. Overview

Active users (monthly) measures the number of unique addresses that initiate revenue-generating transactions on Polkadot AssetHub within a 30-day rolling window. This metric serves as a key indicator of user engagement with the parachain’s core functionalities, including the issuance, management, and transfer of digital assets. By identifying the distinct set of transaction senders, the metric reflects the monthly scale of the active participant base for Polkadot AssetHub.

## 2. Data sources

- **Blockchain events**: `extrinsics` from Polkadot AssetHub
- **External data**: Asset metadata for normalization of transaction details

## 3. Step-by-step calculation

### Component A: Transaction sender extraction

- **Purpose**: To identify the unique addresses initiating activity on the parachain.
- **Logic**: Transaction data is parsed from the `extrinsics` records of Polkadot AssetHub. For every extrinsic, the `id` field is mapped to the user address and the `extrinsic_hash` is captured to identify the unique transaction. The user type is explicitly classified as a transaction sender.
- **Key fields**: `block_timestamp` (timing), `id` (sender address identification), and `extrinsic_hash` (transaction identification).

### Component B: Monthly aggregation

- **Purpose**: To calculate the distinct count of active participants per 30-day window.
- **Logic**: All extracted transaction records are grouped by date, with timestamps truncated to the start of the 30-day rolling window. A distinct count of user addresses is performed for each 30-day rolling window. This ensures that each address is only counted once per 30-day window, regardless of the number of extrinsics submitted by that address.
- **Key fields**: `block_timestamp` (30-day rolling window truncation) and `user_address` (deduplication).

### Component C: Product-level filtering

- **Purpose**: To ensure the metric accurately reflects activity specific to Polkadot AssetHub.
- **Logic**: The dataset is filtered to include only records where the product is identified as Polkadot AssetHub. This isolation prevents the inclusion of activity from the Polkadot Relay Chain or other system parachains, ensuring the metric remains a specific measure of the Polkadot AssetHub ecosystem.
- **Key fields**: `product_id` (set to Polkadot AssetHub).

Blockchains (L2)

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.
