## Entropy Source Failures

Entropy Source Failures occur when the random number generation process in a system becomes predictable or biased, compromising the security of cryptographic operations. In digital finance, secure randomness is essential for everything from key generation to nonce selection in signatures.

If an entropy source fails, an attacker might be able to predict the random numbers, leading to the theft of private keys or the manipulation of protocol outcomes. This is a critical vulnerability that is often overlooked in system design.

Ensuring a high-quality, unpredictable source of entropy is a fundamental requirement for any secure financial application. It serves as the bedrock of cryptographic trust, and its failure can undermine even the most robust protocols.
