Definition ∞ Entropy Failure describes a critical security flaw arising from insufficient randomness in cryptographic processes, particularly when generating private keys or other sensitive data. When entropy is low, the range of possible outcomes is limited, making it easier for attackers to guess or predict values. This compromises the fundamental security of digital assets.
Context ∞ Reports on Entropy Failure often appear in the context of security vulnerabilities discovered in wallet software, hardware devices, or blockchain protocols. Such failures can lead to the compromise of user funds, highlighting the paramount importance of robust random number generation in all cryptographic applications. Developers continuously work to audit and strengthen entropy sources to prevent these exploits.
