The true ingredient of any lottery system to be successful is randomness of its underlying algorithm. Since the introduction of gambling and lottery industry into cryptocurrency market, trust and security have been less of a concern for organizations, unlike randomness and verifiability. Many of the existing lottery designs use dynamic attributes of either game or blockchain to introduce randomness in its algorithm and only a handful of them are verifiable. In this paper, we introduce a lottery system design having novel random function, which uses combination of game and blockchain state to produce randomness in underlying algorithm and is verifiable. Proposed lottery DApp, built on Ethereum platform, includes smart contracts that help system to achieve properties like decentralization, transparency, and immutability. These properties combined with randomness and verifiability lead to this significant lottery design to be unique of its kind.
