Random Number Generators (RNG) are integral to the functionality and fairness of blockchain-based applications, particularly in sectors like gaming, gambling, and various digital platforms. RNGs ensure equitable distribution of resources and rewards, which is fundamental in applications involving substantial economic transactions.

**Smart contracts and the need for true randomness**

Smart contracts, which are autonomous software programs designed for verification and execution. These contracts enable developers to minimize intermediary involvement, reduce costs, and innovate in business and operational models. However, generating truly random numbers within smart contracts presents a significant challenge. The decentralized and transparent nature of blockchains makes them vulnerable to manipulation or bias in number generation, potentially by any network participant.
