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.

Katana Network is a Layer 2 blockchain built on the Agglayer ecosystem.

# Katana Network Block time Methodology

## 1. Overview

Block time measures the average duration required for a new block to be added to Katana Chain. Insight into the network's processing speed and the frequency of state updates is provided by this metric. The latency experienced by users when submitting transactions to the network is reflected by these measurements.

## 2. Data sources

- **Blockchain events**: Block timestamps and block numbers from Katana Network

## 3. Step-by-step calculation

### Component A: Block data extraction

- **Purpose**: Retrieve the sequential and temporal data required for interval analysis
- **Logic**: Block timestamps and block numbers are extracted from the network. The genesis block is filtered out of the dataset to ensure that the initial network timestamp does not skew the subsequent interval calculations.
- **Key fields**: `block_timestamp`, `block_number`

### Component B: Interval determination

- **Purpose**: Calculate the time elapsed between successive blocks
- **Logic**: The time difference between each block and its immediate predecessor is calculated in milliseconds. The timestamps of blocks with consecutive block numbers are compared to ensure the intervals represent the true time between state updates.
- **Key fields**: `block_timestamp`, `previous_timestamp`

### Component C: Daily averaging and aggregation

- **Purpose**: Generate a daily representative value for network performance
- **Logic**: Individual block intervals are aggregated by day using UTC boundaries. An average value is calculated for all intervals recorded within each 24-hour period. The final values are associated with Katana Chain and any gaps in the daily sequence are filled with zeros to maintain a continuous time series.
- **Key fields**: `block_time`, `timestamp`
