## FIFO Ordering

FIFO (First-In-First-Out) Ordering is a transaction sequencing policy where transactions are processed in the exact order they are received by the network. This is the simplest and most transparent form of ordering, as it prevents validators from reordering transactions based on fees or other criteria.

While FIFO is fair in theory, it can be difficult to implement in a distributed network due to network latency and the lack of a global clock. However, it remains a key benchmark for fairness in transaction sequencing and is a common design goal for protocols seeking to minimize MEV.

It promotes a level playing field for all users.
