Rootstock

# Rootstock Block time Methodology

## 1. Overview

Block time measures the average time it takes for a new block to be added to the Rootstock blockchain. 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 frequency of state transitions on the Rootstock sidechain.

## 2. Data sources

- **Blockchain events**: Block headers containing block numbers and timestamps, covering Rootstock

## 3. Step-by-step calculation

### Component A: Block data extraction

- **Purpose**: Retrieve the necessary timing and sequence data for every block on the network.
- **Logic**: Block numbers and their corresponding timestamps are extracted from the Rootstock network. The genesis block (block 0) is explicitly excluded from the dataset to prevent inaccurate interval calculations derived from the Unix epoch start time.
- **Key fields**: `block_number`, `block_timestamp`

### Component B: Block interval measurement

- **Purpose**: Determine the specific duration between sequential blocks.
- **Logic**: Blocks are ordered chronologically by their block number. The time difference is calculated in milliseconds between the timestamp of each block and the timestamp of the block immediately preceding it.
- **Key fields**: `block_timestamp`, `previous_timestamp`

### Component C: Daily averaging and normalization

- **Purpose**: Aggregate individual block intervals into a standardized daily metric.
- **Logic**: All calculated block intervals are grouped by UTC calendar day. The arithmetic mean is calculated for all intervals occurring within each 24-hour period. The resulting values are normalized to ensure consistent data types and are zero-filled for any days where no blocks are recorded to maintain a continuous time series.
- **Key fields**: `timestamp`, `block_time`
