Header Synchronization Latency

Header Synchronization Latency refers to the time delay between a block being produced on a source chain and the destination chain successfully updating its local copy of the source chain header. This delay is influenced by the network speed, the complexity of the verification process, and the block time of the destination chain.

In high-frequency trading or derivative liquidations, even small latencies can create arbitrage opportunities or risks of stale data. Protocols must balance the frequency of updates with the cost of transaction fees to minimize this gap.

Excessive latency can lead to discrepancies in state, potentially allowing users to exploit old price data.
