Research And Implementation Of Key Technology Of Electronic Online Voting System Based On Blockchain

With the progress and development of society,Internet applications have gradually penetrated into all aspects of people’s lives,and electronic online voting has gradually gained widespread attention.The electronic online voting system can span spatial distances and is not subject to time restrictions through online voting.It also eliminates the need for voting activities to be gathered in a fixed place.It is widely recognized for its efficiency and great flexibility.But on the other hand,the online voting method makes the voting participants lose the right to know and supervise the voting process.After online voting,voting participants are worried that the voting data has been tampered with,and the voting participants cannot verify or even know,so the distrust of the voting results has caused the online voting system to fall into a "trust trap",making the application and popularization of the electronic online voting system Being questioned.Based on the analysis of the implementation technology of electronic online voting at home and abroad,the thesis designs and completes a prototype system of electronic online voting system based on Fabric,and uses the blockchain system as a trusted third-party platform to establish a trust base for voting behavior.The thesis focuses on the implementation technology and scheme of establishing a fabric-based trust network,and completes the corresponding design;for specific voting issues,completes the design scheme and implementation architecture of the entire voting system;on the basis of trust,focuses on the research suitable for online voting Smart contract design of the system.Finally,a prototype system for an online voting system based on blockchain was completed,stress tests were conducted,and block destruction query experiments were conducted.The experimental results verify that the system designed by the thesis can solve the main problems of the current electronic online voting system and achieve the expected design and research goals.
