Blockchain based E-Voting system-LITERATURE  SURVEY | IJCT Volume 12 – Issue 6 | IJCT-V12I6P29

The advancement of blockchain and cloud technologies has enabled secure and transparent online voting systems. Traditional voting mechanisms often suffer from issues such as vote tampering, identity fraud, and lack of transparency. The proposed E-voting framework integrates cloud computing with hybrid blockchain technology to ensure a reliable, flexible, and tamper-proof voting process. The system operates through three phases—registration, vote casting, and vote counting—utilizing a timestamp-based authentication protocol and digital signatures for validation. Smart contracts automate transactions while eliminating third-party involvement, and the Practical Byzantine Fault Tolerance (PBFT) algorithm guarantees secure and consistent vote tallying. Performance evaluation demonstrates reduced authentication delay, minimized vote alteration, and improved system latency, offering a more secure and efficient E-voting solution compared to traditional systems.
