Pseudorandom Generation

Definition

Pseudorandom generation involves algorithms that produce sequences of numbers appearing random but are determined by an initial seed value. These sequences are not truly random because they are computationally generated and thus deterministic, meaning the same seed will always produce the same sequence. In blockchain and cryptography, pseudorandom number generators (PRNGs) are utilized for various purposes, including creating private keys, generating nonces, and selecting validators. Their security relies on the practical infeasibility of predicting the next number without knowledge of the seed or previous outputs.
