## Transaction Inclusion Policies

Transaction inclusion policies are the rules and strategies that determine which transactions are prioritized for inclusion in a block. These policies can range from simple gas-price-based ordering to more complex mechanisms that consider user preferences, network congestion, and potential MEV opportunities.

In a competitive block-building environment, these policies directly influence the fairness and efficiency of the network. Transparent and fair inclusion policies are crucial for preventing predatory practices like sandwiching and ensuring that all users have equal access to the blockchain.

As the complexity of block building increases, there is a growing need for standardized and verifiable inclusion policies that align with the broader goals of decentralization and fairness. This is a key area for future protocol upgrades and governance decisions, as it directly impacts the experience of every participant in the decentralized financial system.
