## Churn Limit Constraints

Churn Limit Constraints are technical rules that dictate the maximum number of validators allowed to join or leave a blockchain network within a single epoch. This restriction prevents rapid, large-scale changes to the validator set, which could otherwise be exploited to attack the network.

By limiting the churn rate, the protocol ensures that the validator population remains stable and that consensus remains secure. If too many validators joined or left simultaneously, the network might face volatility in its security budget.

These constraints are hard-coded into the protocol logic. They act as a defense mechanism against sybil attacks and rapid shifts in power.

The churn limit is dynamic in some protocols, adjusting based on the total number of active validators. It is a fundamental parameter for maintaining network health.
