## Transaction Ordering Risks

Transaction Ordering Risks refer to the dangers associated with the sequence in which transactions are processed within a block. Since validators have the power to determine the order of transactions, they can influence the outcome of trades to their advantage or to the advantage of those who pay them.

This risk is a core component of the MEV landscape, where the sequence can be manipulated to create arbitrage or liquidation opportunities. For the average user, this means that their trade might be placed after a price-moving event, leading to worse execution.

Understanding these risks is necessary for developing strategies that are resilient to manipulation. It emphasizes the need for decentralized and fair sequencing protocols to ensure equitable market participation for all users.
