Definition ∞ The Monotonicity Property, in the context of certain blockchain mechanisms or economic models, indicates that a function or system output consistently moves in one direction as its input increases or decreases. For example, transaction fees might only increase with network congestion. This property ensures predictable behavior and prevents erratic or unexpected outcomes. It contributes to the stability and reliability of a protocol.
Context ∞ Ensuring the monotonicity property in critical blockchain functions, such as fee markets or resource allocation, is important for maintaining system predictability and user trust. Deviations from monotonicity can lead to undesirable market behaviors or protocol inefficiencies. Developers often design mechanisms to uphold this property for system robustness.
