# Active users (weekly) Methodology

## 1. Overview

Active users (weekly) measures the number of unique addresses that make a revenue-generating transaction with Polkadot Coretime. This metric reflects the weekly volume of unique transaction signers interacting with the chain to manage or purchase blockspace. Activity is tracked via signed extrinsics submitted to the network within a 7-day rolling window.

## 2. Data sources

- **Blockchain events**: `extrinsic` records from Polkadot Coretime

## 3. Step-by-step calculation

### Component A: Polkadot Coretime extrinsic extraction

- **Purpose**: Capture all transaction activity on the Polkadot Coretime chain.
- **Logic**: All extrinsics are parsed from Polkadot Coretime. The sender address is extracted from the `id` field of each signed extrinsic, along with the corresponding `extrinsic_hash` and `block_timestamp`.
- **Key fields**: `id` (user address), `extrinsic_hash` (transaction hash), and `block_timestamp`.

### Component B: User address identification and filtering

- **Purpose**: Isolate valid transaction signers.
- **Logic**: Extracted addresses are filtered to include only those categorized as 'Transaction sender'. This ensures that the metric captures active participants who initiate and sign transactions on the network.
- **Key fields**: `user_type` (categorized as Transaction sender).

### Component C: Weekly aggregation and deduplication

- **Purpose**: Calculate the unique number of active users per 7-day window.
- **Logic**: User addresses are deduplicated within each 7-day rolling window. Each unique address is counted only once per 7-day window, regardless of the total number of extrinsics submitted by that address. The resulting weekly counts are aggregated to provide the final metric for Polkadot Coretime.

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.
