# Hyperbridge Substrate Block time Methodology

## 1. Overview

Block time measures the average duration between the addition of successive blocks to the Hyperbridge Substrate network. This metric serves as a key indicator of network latency and the speed at which the blockchain updates its state. It reflects the efficiency of the consensus mechanism and the consistency of block production by network validators.

## 2. Data sources

- **Blockchain blocks**: Block headers including block numbers and timestamps from Hyperbridge Substrate
- **External data**: Asset metadata for chain and product identification

## 3. Step-by-step calculation

### Component A: Block data extraction

- **Purpose**: Retrieve the sequence and timing of every block produced on the network.
- **Logic**: Block numbers and their associated timestamps are extracted from the Hyperbridge Substrate ledger. Blocks with a sequence number of zero are filtered out to ensure the genesis block, which is typically timestamped at the beginning of the Unix epoch, does not distort the calculation of intervals.
- **Key fields**: `block_timestamp` and `block_number`.

### Component B: Block interval determination

- **Purpose**: Calculate the specific duration elapsed between consecutive blocks.
- **Logic**: Blocks are sorted in ascending order based on their block number. For every block, the timestamp of the immediately preceding block is identified. The block interval is determined by calculating the difference between the current block timestamp and the previous block timestamp in milliseconds.
- **Key fields**: `block_timestamp` and `previous_timestamp`.

### Component C: Daily averaging and normalization

- **Purpose**: Aggregate individual block intervals into a standardized daily average.
- **Logic**: All calculated block intervals are truncated to a daily grain based on UTC boundaries. The arithmetic mean of all intervals occurring within each 24-hour period is calculated to derive the daily average block time. This value is assigned to the Hyperbridge Substrate product and chain identifiers to ensure consistency with the broader data platform.
- **Key fields**: `block_time`.
