Definition ∞ Bounded randomness describes a system where random outcomes are constrained within a specific, predefined range or set of parameters. In blockchain contexts, this means the unpredictable element, while random, operates within limits set by the protocol rules. This approach provides a controlled degree of unpredictability, essential for predictable yet fair system operation. It helps prevent extreme or undesirable random results that could compromise network stability.
Context ∞ Bounded randomness is frequently discussed in relation to committee selection for consensus protocols or sharding mechanisms. The constraint on randomness is crucial for maintaining a minimum level of security or performance, even with random assignments. Debates often address the balance between sufficient unpredictability for security and the necessary bounds for operational reliability.
