Jailing Mechanism
The jailing mechanism is a temporary suspension of a validator's ability to participate in consensus after they have violated protocol rules or failed to maintain liveness. When a validator is jailed, they are removed from the active set and stop earning rewards, effectively cooling them off.
This serves as a protective measure to prevent a compromised or failing node from continuing to impact the network. To return to the active set, the validator must often perform a manual unjailing procedure or wait for a specific duration to elapse.
This process allows operators to fix technical issues or security vulnerabilities without causing permanent damage to the network. It is a critical component of protocol stability and risk management in proof-of-stake systems.
