What Is “Checkpointing” as a Security Measure?
In cryptocurrency, checkpointing is a security measure where periodic snapshots of a blockchain's state are taken and anchored to a more secure blockchain, like Ethereum. This process ensures that, in the event of a security breach or malicious attack, the system can be reverted to the last known good state, preserving the integrity of the blockchain and its assets.
Checkpoints are a key feature of some blockchain protocols, such as Polygon, to enhance their security.
