What is the Context of Transaction Manipulation?

Concerns regarding transaction manipulation are frequently raised in discussions about front-running, sandwich attacks, and other forms of market abuse within decentralized exchanges and DeFi protocols. Developers are actively working on implementing countermeasures such as private transaction relays and improved transaction ordering mechanisms. Regulatory bodies are also increasing their focus on identifying and penalizing such manipulative activities within the digital asset ecosystem.

Transaction Manipulation

Definition

Transaction manipulation refers to any action taken to improperly alter, delay, or influence the outcome of a transaction on a blockchain or digital ledger. This can involve various deceptive practices aimed at exploiting network vulnerabilities or participant behaviors for illicit gain. Maintaining the integrity of transactions is paramount for the trust and functionality of decentralized systems.
