## Transaction Sequencing Rules

Transaction Sequencing Rules are the protocols or algorithms that determine the order in which transactions are included in a block. In most blockchains, this is primarily determined by gas fees, but this creates an environment where those willing to pay more can effectively control the order of execution.

This has led to the rise of sophisticated strategies that manipulate this ordering to gain an advantage. Future blockchain designs are focusing on more equitable sequencing, such as first-come-first-served models or fair ordering protocols, to prevent the exploitation of transaction order.

These rules are fundamental to the fairness and neutrality of decentralized markets, and they represent a key area of innovation in blockchain infrastructure.
