# Flow Transaction participants (weekly) Methodology

## 1. Overview

Transaction participants (weekly) measures the number of unique addresses that interact with the Flow blockchain within a rolling 7-day window. This metric provides a comprehensive view of network activity by accounting for transaction signers—including payers, proposers, and authorizers—as well as active recipients of non-native assets and NFTs. The metric encompasses activity across both Flow and Flow EVM.

## 2. Data sources

- **Blockchain events**: `Deposited` events from `FungibleToken` and `NonFungibleToken` contracts, along with native transaction signer and transaction initiator data covering Flow and Flow EVM

## 3. Step-by-step calculation

### Component A: Flow participant identification

- **Purpose**: Identifies all unique entities involved in transactions on the Flow blockchain.
- **Logic**: Multiple participant types are parsed from transaction data. Payers (responsible for transaction fees), proposers (owners of the proposal key), and authorizers (accounts authorizing the execution) are extracted. Additionally, recipients of fungible tokens and NFTs are identified via `Deposited` events from `FungibleToken` and `NonFungibleToken` contracts. Because receiving these assets on Flow requires the active setup of vaults or collections by the recipient, these addresses are classified as active participants. For fungible token transfers, the native FlowToken (contract address `1654653399040a61`) is excluded from the receiver logic, as native asset recipients are captured through other transaction roles.
- **Key fields**: `payer`, `proposal_key_address`, `authorizer`, and the `to` field within the `Deposited` event payload.

### Component B: Flow EVM user identification

- **Purpose**: Identifies active addresses within the Flow EVM environment.
- **Logic**: Active addresses are identified by extracting the initiator address from every successful transaction on Flow EVM.
- **Key fields**: `from_address`.

### Component C: Rolling weekly aggregation

- **Purpose**: Calculates the unique count of participants over a 7-day window.
- **Logic**: All unique addresses identified from Flow and Flow EVM are combined into a daily dataset. A rolling window is applied to these daily records, aggregating unique addresses across the current day and the preceding six days. Duplicate addresses appearing multiple times within the 7-day window are counted only once. Calculations are performed daily with UTC day boundaries.

Blockchains (L1)

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

Flow is a smart contract platform for decentralized applications (a blockchain). Flow was founded by Roham Gharegozlou, Dieter Shirley and Mikhael Naayem and launched in 2019.

FLOW holders own and govern the protocol. They currently don’t take a cut of the total transaction fees paid by users (revenue). Flow’s investors include a16z, Coatue, Coinfund, Fabric Ventures, etc.
