## Orphaned Block Rate

The orphaned block rate measures the frequency at which blocks are created but subsequently rejected by the network because they were not part of the longest or main chain. This occurs when two or more miners or validators produce a block at nearly the same time, leading to a temporary fork.

While the orphaned block is valid in its own right, it is not included in the canonical ledger, and the work done to produce it is effectively wasted. A high orphaned block rate is a sign of poor network synchronization or excessive latency.

It can also be an indicator of a network under stress or an inefficient consensus mechanism. Reducing this rate is essential for maximizing the energy and computational efficiency of the blockchain.

It serves as a key performance indicator for the health and responsiveness of the network.
