Logs and Rollback system

Many SMP servers require a system for logging player actions—such as block breaking, interactions with objects, kills, and other events—as well as the ability to roll back those actions.
This is essential for protecting against griefing, restoring accidentally destroyed builds, investigating disputes, and maintaining fair gameplay.

In fact, the lack of such functionality is one of the main reasons why many server owners still avoid using the standard vanilla server and instead rely on third-party patched server cores.

Examples of such systems include plugins like CoreProtect (for Spigot/Paper servers) and Ledger (for Fabric-based servers), which provide detailed action logging and efficient rollback capabilities.
