# Humanity Protocol Block time Methodology

## 1. Overview

Block time measures the average time interval between consecutive blocks produced on the Humanity blockchain, expressed in milliseconds. This metric provides insights into the blockchain's performance and consistency of block production. The calculation determines the time difference between consecutive blocks and aggregates these intervals into daily averages, serving as a key infrastructure performance indicator for the Humanity Layer 2 network.

## 2. Data sources

The calculation uses the following raw data sources:
- **Humanity blockchain block headers**: Raw block data collected from Humanity blockchain nodes, containing fundamental blockchain metrics including block numbers and production timestamps
- **Block timestamp data**: Precise timestamps recording when each block was produced and added to the Humanity blockchain
- **Block sequencing data**: Block numbers providing the sequential order of blocks in the Humanity chain

## 3. Step-by-step calculation

### Component A: Block data extraction
- **Purpose**: Retrieves raw block information from the Humanity blockchain
- **Logic**: Extracts block timestamps and block numbers from Humanity blockchain node data. Filters out the genesis block (block number 0) since it carries a Unix epoch timestamp that would distort block time calculations. Applies incremental processing to focus on recent blocks when updating the metric.
- **Key fields**: `block_timestamp` (when the block was produced), `block_number` (sequential block identifier)

### Component B: Consecutive block pairing  
- **Purpose**: Links each block with its immediate predecessor to enable interval calculation
- **Logic**: Uses a LAG window function to retrieve the timestamp of the previous block for each block, ordered by block number sequence. This creates pairs of consecutive blocks where each block has access to both its own timestamp and the timestamp of the preceding block.
- **Key fields**: `previous_timestamp` (timestamp of the preceding block), maintaining original `block_timestamp` and `block_number`

### Component C: Block interval calculation
- **Purpose**: Computes the actual time difference between consecutive blocks
- **Logic**: Calculates the millisecond difference between each block's timestamp and its predecessor's timestamp. Filters out records where no previous timestamp exists (the first block after genesis). Truncates block timestamps to daily boundaries to prepare for daily aggregation.
- **Key fields**: `block_time` (milliseconds between consecutive blocks), `timestamp` (daily truncated timestamp)

### Final aggregation
- **Combining components**: Groups block intervals by day and calculates the average block time in milliseconds for each day
- **Currency conversion**: Not applicable for this time-based metric
- **Time aggregation**: Daily boundaries are established by truncating block timestamps to day level, ensuring consistent daily reporting periods
- **Final calculation**: The average block time for each day is computed by taking the mean of all individual block intervals within that day. The result is formatted with standard metadata including chain identifier ('humanity'), market sector ('blockchains_l2'), and business segment ('blockchain') classifications. Chain availability filters ensure data quality and completeness.
