Lock-in periods are essential for staking mechanisms, as they dictate how long clients' assets must be staked to qualify for staking rewards. This feature outlines the specific timeframes during which funds must remain locked and the consequences of early withdrawal, such as forfeiting rewards or incurring penalties. The purpose of this feature is to ensure that clients are aware of the commitment required for staking and to maintain the stability of the staking pool by preventing sudden withdrawals that could impact the overall liquidity and reward distribution.
