Expected Constant Time

Definition

Expected constant time refers to an algorithm’s average execution time remaining constant, regardless of the input size. In the context of cryptographic protocols and blockchain operations, this concept means that certain computations are designed to complete within a predictable, fixed duration on average. This predictability is crucial for security, as it prevents timing attacks where an adversary might deduce sensitive information by observing variations in execution time. Achieving expected constant time helps ensure fair and consistent processing across the network.
