P2P Propagation Delay

P2P propagation delay is the time elapsed between a transaction being broadcast by one node and its receipt by the majority of the network. In financial protocols, this delay creates information asymmetry that searchers exploit to gain a competitive advantage.

Reducing this delay involves peering with well-connected nodes and utilizing optimized networking stacks. High propagation delays can lead to stale blocks and failed transactions, increasing the cost of operations.

Understanding this metric is vital for any participant involved in high-frequency on-chain activities. It is a fundamental constraint on the speed of price discovery in decentralized systems.
