Rollback netcode is a method used to ensure correctness and consistency in systems that require real-time interactions, like online gaming or blockchain-based applications. It allows a system to revert to a previous state in case of discrepancies or errors during transactions.In essence, when an event occurs, the system temporarily processes the action. If inconsistencies arise, the system can “rollback” to a prior known good state. This way, it prevents potentially fraudulent activities or mistakes from affecting the overall integrity of the network.This technique is particularly important in environments where multiple parties interact simultaneously. It ensures that everyone has a fair chance and that data remains accurate without the need for extensive waiting times or manual corrections. By maintaining smooth operations while safeguarding against errors, rollback netcode enhances the reliability and user trust in decentralized systems.
