Definition ∞ The manner in which a blockchain validator or miner selects and incorporates pending transactions into a new block. This behavior is influenced by transaction fees, network congestion, and protocol rules. It can reveal patterns related to miner extractable value (MEV) or censorship attempts. Analyzing these patterns helps assess network fairness and efficiency. This process is central to block finalization.
Context ∞ Transaction inclusion behavior is a critical area of study for understanding the economics and fairness of blockchain networks. Discussions often involve the impact of MEV on network participants and efforts to mitigate its negative consequences. Future protocol upgrades aim to create more equitable and transparent transaction ordering mechanisms.
