# Kilt Transactions per second Methodology

## 1. Overview

The transactions per second metric measures the average rate of transaction processing on the KILT Protocol blockchain. This metric calculates the daily transaction throughput by counting unique transactions (extrinsics) per day and dividing by the number of seconds in a day (86,400) to produce an average transactions per second rate. This provides insight into the network's transaction processing capacity and usage patterns.

## 2. Data sources

- **KILT blockchain extrinsics**: Raw transaction records from the KILT Protocol substrate blockchain containing transaction metadata, timestamps, and unique identifiers
- **Substrate chain data**: Transaction-level activity data from the KILT substrate chain infrastructure

## 3. Step-by-step calculation

### Component A: Transaction extraction
- **Purpose**: Extract and standardize raw KILT transaction data
- **Logic**: Raw KILT extrinsics are extracted from the substrate blockchain data. Each record contains a `block_timestamp` indicating when the transaction was processed and an `extrinsic_id` serving as the unique transaction identifier. The timestamps are cast to proper timestamp format and each transaction is labeled with the KILT chain identifier.
- **Key fields**: `block_timestamp` for timing, `extrinsic_id` for unique transaction identification, `chain_id` set to 'kilt'

### Component B: Daily transaction aggregation  
- **Purpose**: Count unique transactions per day to calculate daily transaction volume
- **Logic**: Transactions are grouped by day using timestamp truncation to daily boundaries. For each day, distinct `extrinsic_id` values are counted to avoid double-counting duplicate records. Missing days in the data are filled with zero transaction counts to ensure complete time series coverage. The data is classified under the 'blockchains_l2' market sector and 'blockchain' business segment.
- **Key fields**: `timestamp` truncated to day granularity, `transaction_count` as distinct count of extrinsics, `timestamp_grain` set to 'day'

### Final aggregation
- **Combining components**: The daily transaction counts flow directly from the aggregation component to the final calculation
- **Currency conversion**: No currency conversion required as this is a count-based metric
- **Time aggregation**: Daily transaction counts are maintained at daily granularity
- **Final calculation**: The transactions per second rate is calculated by dividing the daily transaction count by 86,400 (the number of seconds in a day) using safe division to handle potential null or zero values. This produces an average transactions per second rate for each day. Chain availability filtering is applied to ensure data quality and the final schema is validated through the finalization macro.
