# Block time Methodology

## Overview

Block time measures the average time it takes for a new block to be added to the blockchain. It reflects the speed at which the network processes transactions and updates its state.

## Data sources

- Raw block records including sequential block numbers and heights from blockchain networks
- Block header metadata containing precise production timestamps

## Common calculation approaches

### Sequential block interval calculation
Time differences are calculated between consecutive block timestamps to determine the duration of each individual block production. For example, block intervals are derived from Aptos and Movement by subtracting the timestamp of a block from its immediate predecessor.

### Daily average aggregation
Block production consistency is assessed by averaging block intervals over 24-hour periods. Timestamps are paired and aggregated from Arbitrum One and opBNB to provide a smoothed measure of network timing and throughput.

### Network performance normalization
Block height and timestamp data are processed to reflect the frequency of global state updates. This approach is used for data from Solana to evaluate the efficiency of the underlying consensus mechanism and network latency.

**Note:** The calculation approaches and protocol examples above are representative patterns. Individual protocol implementations may vary.
