Front-Running Mitigation

Definition ∞ Front-running mitigation refers to strategies and technical measures designed to prevent malicious actors from profiting by observing pending transactions. These techniques aim to ensure fair transaction ordering and execution on blockchain networks. They protect users from predatory trading practices that exploit information asymmetry. Effective mitigation enhances market integrity and user confidence.
Context ∞ The issue of front-running, particularly in decentralized finance (DeFi), remains a significant concern, leading to continuous efforts in front-running mitigation. Debates center on the efficacy of various solutions, such as encrypted mempools or batch auctions. Observing the implementation of new anti-front-running protocols provides insights into the ongoing pursuit of fair and equitable transaction environments.
