# World Mobile Chain Block time Methodology

## 1. Overview

Block time measures the average time between consecutive block productions on the World Mobile Chain blockchain, expressed in milliseconds and aggregated daily. This metric indicates the blockchain's block production consistency and network performance, answering how efficiently the World Mobile Chain network is producing new blocks over time.

## 2. Data sources

The calculation uses the following raw data sources:
- **World Mobile Chain block headers**: Raw blockchain block metadata containing timestamps and block numbers extracted from World Mobile Chain nodes
- **Block production data**: Fundamental blockchain infrastructure data that records when each block was mined/validated on the World Mobile Chain network

## 3. Step-by-step calculation

### Component A: Block data extraction
- **Purpose**: Extract and clean block timestamp and number data from World Mobile Chain blocks
- **Logic**: The system retrieves block timestamps and block numbers from World Mobile Chain block headers, casting them to proper data types. The genesis block (block number 0) is excluded because it typically has an artificial timestamp at the start of Unix time that would skew block time calculations
- **Key fields**: `block_timestamp` (when the block was produced) and `block_number` (sequential block identifier)

### Component B: Time interval calculation
- **Purpose**: Calculate the time difference between consecutive blocks
- **Logic**: The system uses a window function to pair each block with the immediately previous block's timestamp, ordered by block number. This creates consecutive block pairs needed to calculate individual block production times
- **Key fields**: `block_timestamp`, `previous_timestamp` (timestamp of the preceding block), and `block_number` for proper ordering

### Component C: Block time computation
- **Purpose**: Calculate individual block production times in milliseconds
- **Logic**: For each block pair, the system calculates the millisecond difference between the current block timestamp and the previous block timestamp. Blocks without a previous timestamp (the first block after genesis) are excluded from the calculation
- **Key fields**: `block_time` (milliseconds between consecutive blocks), truncated daily timestamps for aggregation boundaries

### Final aggregation
- **Combining components**: Individual block times are grouped by day using truncated block timestamps
- **Time aggregation**: Block times are averaged within each daily boundary to produce a single daily average block time value
- **Final calculation**: The daily average block time represents the mean time in milliseconds between consecutive block productions for that specific day on World Mobile Chain. The `finalize_metric_block_time` macro adds standard metadata fields including chain identifier and applies consistent formatting across all blockchain metrics.
