What Is the Relationship between Checkpoint Frequency and the Concept of “Finality” in a Blockchain?

The frequency of checkpoints is closely related to the concept of "finality" in a blockchain. Finality is the point at which a transaction can be considered irreversible.

In a blockchain that uses checkpointing, a transaction can be considered "final" once it has been included in a checkpoint that has been anchored to a more secure chain. A higher frequency of checkpoints means that transactions can achieve finality more quickly, which is important for applications that require a high degree of certainty, such as financial transactions.
