This research represents a model of buying and
selling lotteries system on Blockchain by using Ethereum
network to determines the conditions for the purchasing of
the lottery and reward the prize winner. Our system uses
Ethereum coins to buy and reward the prize for convenience

unable to be controlled by the government. For example,
lottery agents (intermediaries) may sell the lottery at overprice, and reward the winners at a lower than appropriate
