# Arc Block time Methodology

## 1. Overview

Block time is defined as the average time required for a new block to be added to the Arc blockchain. The speed at which the network processes transactions and updates its state is reflected by this metric. Latency, throughput, and overall performance of the Arc network are assessed using daily block time measurements. Network stability and operational efficiency are evaluated over time through the aggregation of these block intervals.

## 2. Data sources

- **Blockchain events**: Block timestamps and block numbers extracted from block headers, covering Arc

## 3. Step-by-step calculation

### Component A: Block data extraction and filtering

- **Purpose**: Extract block numbers and timestamps while excluding the genesis block
- **Logic**: Block timestamps and block numbers are extracted from block headers. The genesis block (block number 0) is excluded from the dataset to prevent distortion of the time calculations, as its timestamp is set to the start of Unix time.
- **Key fields**: `block_timestamp`, `block_number`

### Component B: Block interval calculation

- **Purpose**: Calculate the duration between consecutive blocks
- **Logic**: The timestamp of each block is compared to the timestamp of the immediately preceding block. The difference between these two timestamps is calculated in milliseconds to determine the individual block time for each block.
- **Key fields**: `block_timestamp`, `previous_timestamp`

### Component C: Daily aggregation and normalization

- **Purpose**: Calculate the average block time per day
- **Logic**: Individual block times are grouped by day using UTC boundaries. The average block time is calculated for each day by taking the mean of all block intervals recorded within that day. The final values are mapped to the Arc product and chain identifiers.
- **Key fields**: `timestamp`, `block_time`
