# Katana Chain Block time Methodology

## 1. Overview

The average time it takes for a new block to be added to Katana Chain is measured by Block time. The speed at which the network processes transactions and updates its state is reflected by this metric. It is utilized to monitor network performance, latency, and the consistency of the consensus mechanism.

## 2. Data sources

- **Blockchain events**: Block metadata including timestamps and block numbers, covering Katana Chain

## 3. Step-by-step calculation

### Component A: Katana Chain block metadata extraction

- **Purpose**: Retrieve the necessary temporal data for every block produced on the network.
- **Logic**: Block numbers and their associated timestamps are extracted from Katana Chain. The genesis block (block zero) is excluded from the dataset to ensure calculations are based on active network production.
- **Key fields**: `timestamp`, `number`

### Component B: Block interval calculation

- **Purpose**: Determine the duration of time elapsed between successive blocks.
- **Logic**: The time difference between each block and its immediate predecessor is calculated in milliseconds. This is determined by comparing the timestamp of a specific block to the timestamp of the block with the preceding block number.
- **Key fields**: `block_timestamp`, `previous_timestamp`

### Component C: Daily aggregation and normalization

- **Purpose**: Produce a daily average block time metric.
- **Logic**: Individual block intervals are aggregated by day using UTC boundaries. An average value is calculated for each 24-hour period to represent the mean block time. The resulting data is finalized by applying zero-filling for any missing days and filtering based on the latest approved data availability for Katana Chain.
- **Key fields**: `block_time` (average)

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.
