Definition ∞ Time Delay Bypass refers to any method or vulnerability that allows an adversary to circumvent or significantly reduce the intended sequential execution time of a cryptographic function or protocol. This action defeats the security guarantees provided by functions designed to enforce a minimum computation duration. It undermines the integrity of time-based security mechanisms.
Context ∞ The prevention of time delay bypass attacks is paramount for cryptographic primitives like Verifiable Delay Functions (VDFs), which are specifically constructed to ensure that a computation takes a fixed, long sequential time. In blockchain applications, such as fair leader election or randomness generation, protection against these bypasses is crucial for maintaining network security and preventing malicious manipulation.
