# Katana Chain Transaction count Methodology

## 1. Overview

Transaction count is measured as the number of confirmed transactions added to the blockchain. Active user engagement with the network is reflected by this metric. Only transactions confirmed on Katana Chain are included in this calculation. Cross-product aggregation details are provided in the project-level methodology.

## 2. Data sources

- **Blockchain events**: Transaction records from Katana Chain.

## 3. Step-by-step calculation

### Component A: Katana Chain transaction extraction

- **Purpose**: Extract raw transaction data from the blockchain.
- **Logic**: The `block_timestamp`, `transaction_hash`, `from_address`, and `to_address` are parsed from Katana Chain transaction records.
- **Key fields**: `block_timestamp`, `transaction_hash`, `from_address`, and `to_address`.

### Component B: Daily transaction aggregation

- **Purpose**: Aggregate transaction data into daily totals.
- **Logic**: The number of unique `transaction_hash` values is aggregated for each UTC day. Data is grouped by the Katana Chain product identifier and timestamps are truncated to the start of the day to ensure daily granularity.
- **Key fields**: `transaction_count`.

### Component C: Normalization and finalization

- **Purpose**: Validate and finalize the metric for reporting.
- **Logic**: Aggregated counts are validated against canonical data identifiers. A zero-filling strategy is applied to ensure a continuous time series, and a chain availability filter is used to manage data freshness.
- **Key fields**: `timestamp`, `product_id`, and `chain_id`.

The network uses pessimistic proofs via the AgglayerGateway for settlement on Ethereum, with vault bridges for cross-chain asset transfers.

Katana Network provides a scalable execution environment connected to Ethereum through the Agglayer interoperability layer.
