Private Transaction Ordering

Definition ∞ Private transaction ordering refers to methods that allow users to submit transactions to a blockchain network without revealing their order or content to the public mempool before confirmation. This process aims to prevent front-running and other forms of Miner Extractable Value (MEV) exploitation. It offers enhanced privacy and fairness for transaction execution.
Context ∞ The pursuit of private transaction ordering is a critical area of development within blockchain technology, driven by the increasing prevalence of MEV attacks. Solutions range from specialized private relay networks to encrypted mempools, all designed to protect users from predatory trading strategies. The ongoing challenge involves balancing privacy with the decentralized and transparent principles of public blockchains.
