Research on E-voting Based on Blockchain

Network technology is changing with each passing day, and informatization has penetrated in life, which has promoted the development of electronic voting and brought new security tests to the voting system. The continuous development of blockchain technology has gradually developed from Bitcoin as the core support to other fields. The characteristics of decentralization make it a new development direction of electronic voting technology. Based on this, through theoretical analysis, this paper expects to design a relatively safe electronic voting process based on blockchain, and further solve the security problems in the system through auxiliary technology. The system uses the PFBT consensus algorithm to complete the synchronization and consistency problem, which solves the problem of large resource consumption and low data processing efficiency. The POW consensus algorithm enables the system to better meet the voting data processing needs. The design also uses SHA-256 to calculate the hash value, ECDSA algorithm for encryption and decryption, and uses the public key to encrypt the identity information of each voter. At the same time, blind signatures are used in electronic voting to prevent signers or other malicious parties from manipulating or leaking voters' voting results through signature information, which improves the security, privacy protection and fairness of the system.
