What Is the Primary Difference in Front-Running Prevention between a CEX and a DEX?
A Centralized Exchange (CEX) prevents front-running through internal surveillance, regulatory compliance, and a private order book that is not publicly visible until execution. Front-running on a CEX is a violation of market rules and often illegal.
A Decentralized Exchange (DEX) operates on a public blockchain where the order book (mempool) is transparent. Prevention relies on cryptographic and technical solutions like MEV-protection tools and reduced slippage tolerance, as there is no central authority to enforce traditional rules.
