# NeuroWeb Block time Methodology

## 1. Overview

Block time measures the average time interval between consecutive blocks on the Neuroweb blockchain network. This metric indicates network performance and block production consistency by calculating the time elapsed between when each block is mined compared to its predecessor. The calculation produces daily aggregated average block times expressed in milliseconds, providing insight into blockchain throughput and network health.

## 2. Data sources

The calculation relies on:
- **Neuroweb blockchain block headers**: Raw block data including block numbers and timestamps from the Neuroweb network
- **Block metadata**: Fundamental blockchain data containing the sequential block number and exact timestamp when each block was mined
- **Network block production data**: Complete chronological sequence of blocks to enable consecutive block time calculations

## 3. Step-by-step calculation

### Component A: Block data extraction and filtering
- **Purpose**: Extract clean block data and remove invalid entries
- **Logic**: The process begins by extracting block timestamps and block numbers from raw Neuroweb blockchain block data. The genesis block (block number 0) is filtered out because it contains an invalid timestamp set to the Unix epoch start time, which would skew block time calculations. Only blocks with valid sequential numbers greater than zero are retained for analysis.
- **Key fields**: `block_timestamp` contains the exact time when each block was mined, `block_number` provides the sequential block identifier

### Component B: Consecutive block pairing
- **Purpose**: Create pairs of consecutive blocks to enable time interval calculations
- **Logic**: Using a window function ordered by block number, each block is paired with the timestamp of the immediately preceding block. This creates the necessary data structure to calculate time differences between consecutive blocks in the blockchain sequence. Blocks without a preceding block (the first valid block after genesis) are excluded since no time interval can be calculated.
- **Key fields**: `previous_timestamp` contains the timestamp of the prior block for each block pair

### Component C: Block time interval calculation
- **Purpose**: Calculate the actual time elapsed between consecutive blocks
- **Logic**: For each valid block pair, the time difference is calculated in milliseconds between the current block timestamp and the previous block timestamp. This represents the actual block production time - how long it took from one block being mined to the next block being mined. Results are grouped by day using timestamp truncation.
- **Key fields**: `block_time` contains the calculated interval in milliseconds, `timestamp` represents the daily grouping boundary

### Final aggregation
- **Combining components**: Daily block times are aggregated using the average function to produce a single representative block time value for each day
- **Currency conversion**: Not applicable for this time-based metric
- **Time aggregation**: Block times are grouped by calendar day boundaries, with each day receiving its own average block time calculation
- **Final calculation**: The final metric represents the average time in milliseconds between consecutive blocks for each day, enriched with metadata identifying the chain as Neuroweb in the layer-2 blockchains market sector. Missing days are filled with zeros using the fill strategy, and chain availability filtering ensures data quality standards are met.
