> The checkpoint process can potentially be interrupted by a catastrophic
> failure such as complete power loss leaving the checkpoint corrupted. When
> the channel is restarted, the (corrupted) checkpoint will get loaded and
> there could be dataloss as a result of this.
> It is therefore necessary to have a safeguard to detect if a checkpoint
> succeeded or failed.
