# Soneium Block time Methodology

## 1. Overview

Block time measures the average time interval between consecutive blocks on the Soneium blockchain, expressed in milliseconds and aggregated daily. This metric indicates blockchain network performance and consistency, showing how regularly new blocks are produced. The calculation determines the time difference between each block and its immediate predecessor, then averages these intervals by day to provide a daily block time metric.

## 2. Data sources

The metric relies on:
- **Soneium blockchain block data**: Raw block information directly from Soneium network nodes, containing native block timestamps and sequential block numbers for each block produced on the network

## 3. Step-by-step calculation

### Component A: Block data extraction
- **Purpose**: Retrieves block timestamps and numbers while filtering out anomalous genesis block
- **Logic**: Extracts `block_timestamp` and `block_number` fields from Soneium blockchain data. Excludes the genesis block (block number 0) which typically has an anomalous timestamp at the start of Unix time that would distort block time calculations. For incremental processing, includes blocks from recent days with configurable lookback period.
- **Key fields**: `block_timestamp` (when the block was mined), `block_number` (sequential block identifier)

### Component B: Consecutive block pairing
- **Purpose**: Links each block with its immediate predecessor to enable time difference calculations
- **Logic**: Uses LAG window function ordered by block number ascending to retrieve the timestamp of the previous block for each current block. This creates pairs of consecutive blocks needed for interval calculations.
- **Key fields**: `block_timestamp` (current block time), `previous_timestamp` (preceding block time), `block_number` (block sequence)

### Component C: Block time interval calculation  
- **Purpose**: Computes the actual time elapsed between consecutive blocks
- **Logic**: Calculates millisecond differences between each block's timestamp and its predecessor using timestamp difference function. Truncates block timestamps to daily boundaries for aggregation grouping. Excludes the first block which has no predecessor.
- **Key fields**: `timestamp` (daily truncated date), `block_time` (milliseconds between blocks)

### Final aggregation
- **Combining components**: Aggregates all block time intervals within each day using average function to determine typical block production speed
- **Currency conversion**: Not applicable for time-based metrics
- **Time aggregation**: Daily boundaries determined by truncating block timestamps to day precision, grouping all blocks mined within the same calendar day
- **Final calculation**: Average of all individual block time intervals (in milliseconds) for each day, providing the mean time between consecutive blocks. Includes metadata fields identifying the chain as Soneium, market sector as layer-2 blockchains, and business segment as blockchain infrastructure.
