Movement

# Movement Block time Methodology

## 1. Overview

Block time measures the average time interval between consecutive blocks on the Movement blockchain, expressed in milliseconds. This metric provides insight into the blockchain's performance and consistency, helping assess network throughput and stability. The calculation determines the time difference between each consecutive block pair and aggregates these intervals into daily averages.

## 2. Data sources

The calculation relies on:
- **Movement blockchain block data**: Raw block information from the Movement blockchain containing block timestamps and block numbers/heights
- **Block metadata**: Each block record includes a timestamp indicating when the block was created and a sequential block number

## 3. Step-by-step calculation

### Component A: Block data extraction
- **Purpose**: Retrieves and prepares raw block information from the Movement blockchain
- **Logic**: Extracts block timestamps and block numbers from Movement blockchain block records, converting block heights to integers. Filters out the genesis block by requiring block numbers greater than zero to focus on actual network activity
- **Key fields**: `block_timestamp` (when each block was created), `block_number` (sequential block identifier), `chain` (set to 'movement')

### Component B: Time difference calculation
- **Purpose**: Calculates the time interval between each consecutive block pair
- **Logic**: Uses window functions to access the previous block's timestamp and number for each block, ordered by block number. Computes the time difference in milliseconds between the current block and its immediate predecessor. Filters to ensure only truly consecutive blocks are included by verifying the block number difference equals exactly 1
- **Key fields**: `block_time` (milliseconds between consecutive blocks), `previous_timestamp` (timestamp of preceding block), `previous_block_number` (number of preceding block)

### Final aggregation
- **Combining components**: Block time intervals are grouped by day using timestamp truncation to day granularity
- **Currency conversion**: Not applicable for this time-based metric
- **Time aggregation**: Daily boundaries are established by truncating block timestamps to day level, with all block times within each day contributing to that day's average
- **Final calculation**: The average block time for each day is calculated using the mean of all valid consecutive block time intervals within that day, expressed in milliseconds. The result includes standard metric metadata identifying Movement as an L2 blockchain in the blockchain business segment
