## Orphan Block Rates

Orphan block rates refer to the frequency at which valid blocks are produced but ultimately discarded because they were not part of the main chain. This usually happens when two miners or validators produce blocks simultaneously, and the network eventually chooses one over the other.

A high orphan rate indicates network inefficiency or significant latency, which can undermine security and reduce throughput. In the context of financial derivatives, high orphan rates can lead to confusion regarding the true state of the market.

Reducing this rate is a priority for protocol developers to ensure a smooth, singular history of transactions. It serves as a metric for the health of the consensus process.
