What Is the Role of Validators in the Checkpointing Process?
In the checkpointing process, validators are responsible for reaching a consensus on the state of the blockchain at a specific point in time. They collectively create a snapshot of the blockchain's state, sign it with their cryptographic keys to attest to its validity, and then submit this snapshot to the anchor chain.
This process ensures that the checkpoint is a true and accurate representation of the blockchain's history, and it prevents any single validator or small group of validators from submitting a fraudulent checkpoint.

Checkpointing Process
Procedure ⎊ This systematic process involves periodically recording the entire state of the ledger onto a more permanent or easily verifiable structure, often across different consensus layers.
Checkpointing
Finality ⎊ Checkpointing is a mechanism in Proof-of-Stake protocols designed to establish transaction finality by creating irreversible points in the blockchain history.
Validators
Attestation ⎊ Validators, within cryptocurrency networks, represent nodes actively participating in a consensus mechanism, verifying and attesting to the validity of new blocks or transactions.
