# Front-Running Attacks ⎊ Area ⎊ Resource 11 --- ## What is the Attack of Front-Running Attacks? Front-running attacks occur when a malicious actor observes a pending transaction in the mempool and submits a new transaction with a higher gas fee to ensure their transaction is processed first. This allows the attacker to profit from the information contained within the original transaction, typically by executing a trade that anticipates the price movement caused by the victim's transaction. The attack exploits the transparency and sequential nature of blockchain transaction processing. ## What is the Mechanism of Front-Running Attacks? The mechanism of front-running relies on the ability of miners or sophisticated bots to reorder transactions within a block based on gas fees. In decentralized exchanges, a front-running bot might observe a large buy order, execute its own buy order immediately before the victim's transaction, and then sell the asset at a higher price after the victim's order increases the market price. This results in a loss for the original trader and a profit for the attacker. ## What is the Consequence of Front-Running Attacks? The consequence of front-running attacks is reduced market efficiency and significant financial losses for traders, particularly those executing large orders. This type of market manipulation undermines fair price discovery and creates an environment where sophisticated actors can extract value from less informed participants. Mitigation efforts focus on implementing mechanisms like batch auctions and encrypted transaction pools to obscure order information from front-running bots. --- ## [Oracle Attack Cost](https://term.greeks.live/term/oracle-attack-cost/) Meaning ⎊ Oracle Attack Cost quantifies the capital required to compromise decentralized price feeds, serving as a critical metric for derivative system safety. ⎊ Term ##
