World Chain is designed as a Layer 2 blockchain built on the OP Stack and optimized for verified humans. It leverages World ID, a privacy-preserving proof of personhood, to prioritize real users over bots and Sybil attackers. It integrates with World App and other identity wallets using Safe smart contract infrastructure.

World Chain is an Ethereum Layer 2 chain that enables applications to distinguish between bots and verified humans. It forms a core part of the Worldcoin ecosystem, aiming to power more human-centric onchain activity by prioritizing real people in blockspace allocation and transaction processing.

World Chain is developed by the team behind Worldcoin, which is currently governed by the Worldcoin Foundation. Worldcoin's investors include a16z, Multicoin Capital, 1confirmation, CoinFund, among others.

# World Chain Transaction count Methodology

## 1. Overview

Transaction count measures the daily number of distinct transactions on the Worldchain blockchain, grouped by recipient address. This metric provides insight into transaction volume and activity patterns on Worldchain, tracking how many unique transactions are sent to each destination address each day. The calculation uses approximate distinct counting to handle potential duplicate transaction records and applies standardized metric processing to ensure data quality and consistency.

## 2. Data sources

The metric relies on these underlying data sources:

- **Worldchain transaction records**: Complete transaction data from the Worldchain blockchain, including transaction hashes, sender/recipient addresses, and block timestamps
- **Incremental processing metadata**: Table modification tracking data used to optimize incremental data processing and determine processing boundaries

## 3. Step-by-step calculation

### Component A: Transaction data preparation
- **Purpose**: Standardizes raw Worldchain transaction data for metric calculation
- **Logic**: Selects core transaction fields from Worldchain blockchain records and casts them to appropriate data types. Extracts the `block_timestamp`, `transaction_hash`, `from_address`, and `to_address` fields, ensuring consistent string and timestamp formatting. Tags all records with the chain identifier 'worldchain' for downstream processing.
- **Key fields**: `block_timestamp` (transaction timing), `transaction_hash` (unique transaction identifier), `from_address` (sender), `to_address` (recipient), `chain` (blockchain identifier)

### Component B: Daily transaction aggregation
- **Purpose**: Aggregates transaction counts by day and recipient address
- **Logic**: Groups transaction data by daily time boundaries using timestamp truncation on `block_timestamp`. For each day and recipient address combination, calculates the approximate distinct count of `transaction_hash` values to determine unique transactions. Applies standardized metadata tagging including chain identifier ('worldchain'), market sector ('blockchains_l2'), and business segment ('blockchain'). Uses approximate counting to efficiently handle large transaction volumes while maintaining accuracy.
- **Key fields**: `timestamp` (daily boundary), `transaction_count` (distinct transaction count), `to_address` (recipient address), standard metadata fields for categorization

### Final aggregation
- **Combining components**: The transaction preparation feeds directly into the daily aggregation component, with no additional joining required
- **Currency conversion**: Not applicable - this is a count-based metric with no monetary values
- **Time aggregation**: Daily boundaries are established by truncating block timestamps to day precision, ensuring consistent daily reporting periods
- **Final calculation**: The final transaction count represents the approximate distinct count of transaction hashes grouped by recipient address and day, processed through standardized metric finalization that includes schema validation, ID validation, and zero-filling for any missing days to maintain complete time series continuity
