Transaction Inclusion Rule

Definition ∞ A transaction inclusion rule defines the specific criteria and logic that determine whether a transaction is valid and eligible to be added to a blockchain block by a validator or miner. These rules typically cover aspects like correct cryptographic signatures, sufficient funds, and adherence to protocol-specific parameters such as gas limits. Adherence to these rules is essential for maintaining the integrity and security of the entire ledger. It ensures only legitimate operations are recorded.
Context ∞ News frequently references transaction inclusion rules when discussing network congestion, fee market dynamics, or protocol upgrades that modify how transactions are processed. Any alteration to these rules can have significant implications for network performance, security, and user costs. Understanding these rules is crucial for interpreting blockchain activity reports and assessing the operational health of decentralized networks.
