What is the Definition of Front-Running Prevention?

Front-running prevention refers to mechanisms designed to stop malicious actors from exploiting information about pending transactions to their own advantage. In blockchain systems, this typically involves preventing a transaction from being executed before another, more profitable one, thereby ensuring fairness in execution order. Such measures are vital for maintaining market integrity.

What is the Context of Front-Running Prevention?

The development and implementation of front-running prevention techniques are prominent topics in the optimization of decentralized exchanges and other on-chain trading protocols. Discussions frequently address the efficacy of various methods, such as private transaction relays, commit-reveal mechanisms, and batch auctions, in mitigating this threat. Ongoing research seeks to create more resilient systems against such predatory practices.
