# Robinhood Chain Block Time Methodology

## 1. Overview

Block Time is defined as the average duration of time required to produce a new block on Robinhood Chain. This metric is utilized to assess the throughput, latency, and operational efficiency of the network. By monitoring the average time elapsed between consecutive blocks, network performance and stability can be evaluated over time. These measurements are aggregated daily to provide institutional-grade insights into the blockchain's performance.

## 2. Data sources

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

## 3. Step-by-step calculation

### Component A: Block data extraction

- **Purpose**: Retrieve block numbers and timestamps from the blockchain
- **Logic**: Block numbers and timestamps are extracted from the block headers of Robinhood Chain. The genesis block (block number 0) is excluded from the dataset to prevent distortion from the initial Unix epoch timestamp.
- **Key fields**: `block_timestamp` (timing), `block_number` (block sequence)

### Component B: Block interval calculation

- **Purpose**: Determine the time elapsed between consecutive blocks
- **Logic**: For each block, the timestamp of the immediately preceding block (ordered by block sequence) is retrieved. The difference between the current block's timestamp and the previous block's timestamp is calculated in milliseconds to determine the individual block interval.
- **Key fields**: `block_timestamp` (current block time), `previous_timestamp` (preceding block time)

### Component C: Daily aggregation and normalization

- **Purpose**: Calculate the daily average block time
- **Logic**: Individual block intervals are grouped by day based on the block timestamp truncated to UTC day boundaries. The average of these intervals is calculated for each day to produce the daily average block time. The final daily values are outputted in milliseconds, with days containing no block activity represented as zero.
- **Key fields**: `timestamp` (daily boundary), `block_time` (average block duration in milliseconds)
