## Order Book Fairness

Order book fairness ensures that all participants have equal access to the matching engine and that orders are processed in a transparent, non-discriminatory manner. This involves preventing front-running, where certain participants use privileged information to jump ahead of other orders.

In centralized exchanges, this is managed through strict regulatory compliance and sophisticated internal auditing. In decentralized systems, fairness is challenged by the transparency of the mempool, where transactions can be observed before they are included in a block.

Achieving fairness in decentralized order books requires innovative cryptographic solutions to hide order details until they are finalized, ensuring a level playing field for all traders.
