Decentralized Electronic Vote Based on Blockchain P2P

Voting has become one of the methods used by humans to determine decisions in a matter. As technology has developed, conventional Voting has also followed the transformation in the adaptation of today's digital age. There is an electronic version of this Voting, often referred to as e-voting (electronic Voting). Of course, the application of technology in Voting will lead to public opinion about concerns about maintaining network privacy and security in e-voting. Security problems can be overcome with technology that is currently being maximally utilized in various fields of life, namely blockchain technology. In improving the security of e-voting, Blockchain is used in P2P networks. Implementing the blockchain system in e-voting will result in a secure e-voting system to reduce the percentage of vote forgery in the e-voting system. Implementing a blockchain-based e-voting system will involve cryptography, software engineering theory, and voting theory. In realizing blockchain-based e-voting, several stages are required. (1) Counterfeit votes avoid adjusting the voting record model based on ledger technology, (2) in terms of authentication. The technology complemented by designing a user model based on Elliptic Curve Cryptography (ECC), (3) providing a model designed for voters to change their votes before the time limit specified. The implementation of Blockchain in this e-voting system is transparent with the existence of a blockchain system that provides notifications to all nodes to approve an incoming vote data. With this transparency, it can reduce fraud and the election of leaders according to people's choices.
