Back Running Defense

Definition

Back running defense describes mechanisms designed to counter back running, a form of front running where a malicious actor observes a pending transaction and submits their own transaction to execute immediately after it. These defenses aim to protect users from predatory trading practices on decentralized exchanges and other blockchain applications. Such measures help preserve fair transaction ordering and prevent value extraction by exploiting predictable transaction outcomes. They are crucial for maintaining market integrity in high-frequency trading environments.
