# Boba Network Block time Methodology

## 1. Overview

The block time metric measures the average time interval between consecutive blocks produced on the Boba Network blockchain, aggregated daily. This metric indicates blockchain performance and network efficiency by tracking how consistently blocks are being produced. Block time is a fundamental blockchain health metric that reflects network congestion, validator performance, and overall system stability.

## 2. Data sources

The calculation uses the following raw data sources:

- **Boba Network blockchain data**: Block-level data including timestamps and sequential block numbers from Boba Network blockchain nodes
- **Block metadata**: Block production timestamps and sequential numbering system that tracks when each block was created and validated

## 3. Step-by-step calculation

### Component A: Block data extraction
- **Purpose**: Extract clean block timing data from the Boba Network blockchain
- **Logic**: Raw block data is retrieved containing `block_timestamp` and `block_number` fields. The genesis block (block number 0) is explicitly excluded because it has an artificial timestamp set to the Unix epoch start rather than reflecting actual block production time. Data types are safely cast to ensure timestamp and integer formats are consistent.
- **Key fields**: `block_timestamp` (when the block was produced), `block_number` (sequential block identifier)

### Component B: Temporal sequencing
- **Purpose**: Pair each block with its predecessor to enable interval calculation
- **Logic**: Blocks are ordered sequentially by `block_number` and a LAG window function retrieves the timestamp of the previous block for each row. This creates pairs of consecutive blocks with their respective timestamps, enabling calculation of the time elapsed between block productions.
- **Key fields**: `previous_timestamp` (timestamp of the preceding block), maintaining original `block_timestamp` and `block_number`

### Component C: Block interval calculation
- **Purpose**: Calculate the actual time taken to produce each block
- **Logic**: For each block pair, the time difference between the current block timestamp and the previous block timestamp is calculated in milliseconds using timestamp difference functions. Blocks are grouped by daily boundaries using timestamp truncation to the day level. Any blocks where no previous timestamp exists (the first block in the dataset) are filtered out since no interval can be calculated.
- **Key fields**: `block_time` (interval in milliseconds), `timestamp` (daily boundary), standard metadata fields for chain identification

### Final aggregation
- **Combining components**: All block time intervals within each day are averaged to produce a single daily block time value, smoothing out variations and providing a stable daily performance metric
- **Currency conversion**: Not applicable for this timing-based metric
- **Time aggregation**: Data is aggregated to daily boundaries with each day representing the average block production time across all blocks produced that day
- **Final calculation**: The average block time per day is calculated by taking the arithmetic mean of all individual block intervals (in milliseconds) within each 24-hour period, providing a daily performance indicator for the Boba Network blockchain
