## Uncle Block Rate

The uncle block rate measures the frequency of blocks that are mined but not included in the main chain, often due to network latency or simultaneous block production. These blocks, while valid, do not contribute to the main chain's security and represent wasted computational effort.

A high uncle rate often indicates network congestion or inefficient propagation, which can negatively impact the overall stability of the blockchain. In terms of protocol physics, a high rate can lead to reduced security margins and increased vulnerability to certain types of attacks.

Monitoring this metric helps in optimizing the network for faster, more reliable consensus.
