# OKX Block time Methodology

## 1. Overview

Block time is measured as the average time it takes for a new block to be added to the blockchain. The speed at which the network processes transactions and updates its state is reflected by this metric. For X Layer, network latency, throughput, and overall operational efficiency are evaluated using daily block time averages. Predictable transaction settlement and a stable user experience are supported by consistent block times.

## 2. Data sources

- **Blockchain events**: Block headers containing block numbers and timestamps, covering X Layer

## 3. Step-by-step calculation

### Component A: Block metadata extraction

- **Purpose**: Extract and clean block timestamps and block numbers
- **Logic**: Block timestamps and block numbers are extracted from block headers. The genesis block (block number 0) is excluded from the dataset to prevent distortion of the calculation from the initial Unix epoch timestamp.
- **Key fields**: `block_timestamp` and `block_number`

### Component B: Block interval calculation

- **Purpose**: Determine the duration between consecutive blocks
- **Logic**: Block timestamps are ordered chronologically by block number. The timestamp of the previous block is subtracted from the timestamp of the current block to calculate the block interval in milliseconds.
- **Key fields**: `block_timestamp` and `previous_timestamp`

### Component C: Daily averaging and normalization

- **Purpose**: Aggregate block intervals into a daily average block time
- **Logic**: Block intervals are grouped by day using UTC boundaries. The average block time is calculated for each day by taking the mean of all block intervals within that day. The final values are cast to float64 and any missing days are filled with zeros to ensure a continuous time series.
- **Key fields**: `block_time` and `timestamp`
