Locking mechanisms are integral to various blockchain applications, providing a way to secure assets by freezing them temporarily or until certain actions occur. These mechanisms are often utilized in decentralized finance (DeFi) to ensure that liquidity is maintained or that collateralized loans are protected from defaults. They can take many forms, including time-locks, where assets are locked for a predefined period, and condition-based locks, which require specific conditions to be satisfied before unlocking.
