The Blockchain is one of the recent technologies that have emerged in the last decade. Blockchain has become a topic of many researches in several fields and it was implemented in some industries like finance, energy, health care, and electronic voting. Blockchain presents some great potential solutions that help to tackle difficulties. In this work we will focus on e-voting using blockchain technology. As we all know the voting is a way that leads the governments to approach democracy in their countries by an electoral process. The blockchain voting has replaced the traditional vote paper, also it replaced the voting systems that store data in central database. That gave much efficiency to the blockchain technology through a decentralized system that requires anonymity, confidentiality and transparency.
