# Bifrost Substrate Block time Methodology

## 1. Overview

Block time measures the average duration required for a new block to be added to the Bifrost Substrate blockchain. This metric reflects the operational speed of the network and the frequency at which the system state is updated and transactions are finalized. It serves as a key performance indicator for the underlying Substrate infrastructure of the Bifrost protocol.

## 2. Data sources

- **Blockchain events**: Block metadata including timestamps and block heights from Bifrost Substrate

## 3. Step-by-step calculation

### Component A: Block data extraction

- **Purpose**: To retrieve the foundational timing and sequencing data from the blockchain.
- **Logic**: Block numbers and their corresponding timestamps are extracted from the network. The genesis block is filtered out from the dataset to prevent timestamp anomalies from affecting the calculation.
- **Key fields**: `block_timestamp`, `block_number`

### Component B: Block interval calculation

- **Purpose**: To determine the duration of the interval between consecutive blocks.
- **Logic**: The time difference between the timestamp of a specific block and the timestamp of the preceding block is calculated. These intervals are measured at millisecond precision to ensure granular accuracy in the subsequent averaging process.

### Component C: Daily aggregation and normalization

- **Purpose**: To provide a standardized daily average of the network's block time.
- **Logic**: All individual block intervals recorded within a UTC day are aggregated. The mean value of these intervals is calculated to represent the average block time for that day. The resulting values are cast to appropriate numeric types, and a zero-filling strategy is applied to ensure a continuous time series for periods without recorded activity. Missing days are filled with zeros to maintain data integrity across the reporting period.

Blockchains (L2)

Collators aggregate parachain transactions block candidates and producing state transition proofs for validators based on those blocks.

Bifrost is the Staking Yield Layer app-chain for stablecoins, RWAs, and DeFi, powered by the Polkadot Relay chain.

BNC holders own and govern the protocol. Bifrost’s investors include OKX Ventures, Long Hash Ventures, etc.
