## Heartbeat Update Frequency

The Heartbeat Update Frequency is the interval at which an oracle updates the price data on the blockchain, even if the asset price has not changed significantly. This ensures that the protocol always has access to a relatively fresh price feed, reducing the risk of using stale data.

A shorter heartbeat frequency provides more accurate and responsive data, which is crucial for high-frequency derivative trading and rapid liquidation triggers. However, more frequent updates increase the gas costs for the protocol or the oracle provider.

Finding the right balance between update frequency and cost is a key design decision for any oracle-dependent system. If the heartbeat is too slow, the protocol may be vulnerable to market movements that occur between updates.

It is a fundamental parameter in maintaining the real-time accuracy required for sophisticated financial instruments on-chain.
