Randomness Generation Protocol

Definition ∞ A randomness generation protocol is a set of rules and algorithms designed to produce unpredictable and verifiable random numbers within a distributed system. In blockchain contexts, these protocols are crucial for applications requiring unbiased selection, such as leader election or lottery mechanisms. The output must be resistant to manipulation by any single participant or group. This ensures fairness and security in decentralized processes.
Context ∞ The reliable generation of unpredictable on-chain entropy remains a significant challenge and active research area in blockchain technology, often referred to as the randomness trilemma. Debates focus on achieving security, decentralization, and availability simultaneously. News frequently reports on new approaches, such as verifiable random functions (VRFs) or time-lock puzzles, aimed at improving the integrity of randomness in decentralized applications.
