# Hydration Block time Methodology

## 1. Overview

Block time measures the average time it takes for a new block to be added to the Hydration Substrate network. It reflects the speed at which the network processes transactions and updates its state. This metric is a key indicator of network latency and the efficiency of the underlying consensus mechanism.

## 2. Data sources

- **Blockchain events**: Block headers containing block numbers and timestamps from Hydration Substrate
- **External data**: None required for this metric

## 3. Step-by-step calculation

### Component A: Block data extraction

- **Purpose**: Retrieve the necessary sequence and timing information from the blockchain.
- **Logic**: Block numbers and their corresponding timestamps are extracted from the network. The genesis block (block 0) is excluded from the dataset to prevent skewed results caused by its initial timestamp.
- **Key fields**: `block_number` (sequence), `block_timestamp` (timing)

### Component B: Block interval calculation

- **Purpose**: Measure the duration between successive blocks.
- **Logic**: The time difference between each block and its immediate predecessor is calculated in milliseconds. This identifies the specific production time for every individual block in the sequence.
- **Key fields**: `block_time` (calculated as the difference between current and previous timestamps)

### Component C: Daily averaging and normalization

- **Purpose**: Provide a representative daily value for network performance.
- **Logic**: All individual block intervals are aggregated by day based on UTC boundaries. The average of these intervals is calculated to produce the daily block time metric. Missing data points are handled via a zero-fill strategy to ensure continuous time-series reporting.
- **Key fields**: `timestamp` (UTC day), `block_time` (average duration)
