Definition ∞ Zero-Fee Inclusion refers to a mechanism within a blockchain protocol that allows certain transactions to be processed and included in a block without requiring an explicit transaction fee. This feature might be implemented for specific types of system-level operations, internal protocol messages, or as part of a design to subsidize user activity. It aims to reduce friction for particular interactions. Such inclusion can enhance network utility.
Context ∞ The implementation of zero-fee inclusion is often a topic of debate concerning network economics, spam prevention, and equitable access. While it can improve user experience for specific actions, it also requires careful design to prevent network abuse. Understanding this mechanism provides insight into a protocol’s economic design choices and its approach to user incentives.
