# Story Protocol Block time Methodology

## 1. Overview

Block time measures the average time interval between consecutive blocks produced on the Story Protocol blockchain, calculated daily. This metric provides insight into the blockchain's performance and network efficiency by tracking how consistently blocks are being produced. The calculation takes raw blockchain block data, computes the time differences between consecutive blocks, and averages these intervals on a daily basis.

## 2. Data sources

- **Story Protocol blockchain blocks**: Raw block data from the Story Protocol network containing block headers with timestamps and sequential block numbers
- **Block metadata**: Block timestamps indicating when each block was mined/validated and block numbers providing sequential ordering

## 3. Step-by-step calculation

### Component A: Block data extraction
- **Purpose**: Extract and prepare raw block data from the Story Protocol blockchain
- **Logic**: Retrieves block timestamps and block numbers from Story Protocol blockchain block headers. The genesis block (block number 0) is excluded because it typically has an artificial timestamp set to the Unix epoch start, which would skew block time calculations
- **Key fields**: `block_timestamp` (when the block was produced) and `block_number` (sequential block identifier)

### Component B: Consecutive block pairing
- **Purpose**: Pair each block with its immediately preceding block to enable time difference calculations
- **Logic**: Uses a lag window function ordered by block number to access the timestamp of the previous block for each current block. This creates pairs of consecutive blocks where time differences can be calculated
- **Key fields**: `block_timestamp` (current block time), `previous_timestamp` (preceding block time), and `block_number` for ordering

### Component C: Block time interval calculation
- **Purpose**: Calculate the actual time elapsed between consecutive blocks
- **Logic**: Computes the millisecond difference between each block's timestamp and its predecessor's timestamp using timestamp difference functions. Rows where no previous timestamp exists (the first block after genesis) are filtered out
- **Key fields**: `block_time` (milliseconds between consecutive blocks), `timestamp` (truncated to daily boundaries for aggregation)

### Final aggregation
- **Combining components**: Individual block time intervals are grouped by day using timestamp truncation to daily granularity
- **Time aggregation**: All block times within each calendar day are averaged to produce a daily average block time metric
- **Metadata assignment**: The metric is classified with chain identifier 'story', market sector 'blockchains_l2', and business segment 'blockchain'
- **Final calculation**: The average block time in milliseconds per day, representing the typical time interval between blocks on the Story Protocol network for each day
