Front-running is a practice where a broker or trader executes orders on a security for their own account while taking advantage of advance knowledge of pending orders from their clients. This unethical practice can lead to increased costs for clients and undermines the trust necessary in financial markets. Within the realm of decentralized applications (DApps) and blockchain technology, front-running can occur when miners or validators exploit transaction ordering to benefit from market movements before the actual trades are executed.
