Design of Blockchain Lottery for Thai Government

Abstract

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 in term of speed and also reduce the problems which is 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 rate. Additionally, the most important problem is the verification of the real owner of the lottery.
