In the presence of the President of the University, Prof. Imran Gamal Hassan, and his scientific assistant, Prof. Ahmed Abdel Ibrahim, the College of Computer Science and Information Technology discussed the master's thesis entitled "electronic voting system based on the smart contract using Blockchain technology". Dr. Ahmed Chalak Shakir. The proposed system has two parts: the first is a web application for electronic registration before the elections; And the mobile application part for voting by the voter, the proposed system used QR code technology and fingerprint and face technology to enter the system, as the blocks are linked to the SHA-256 algorithm with a prefix of three zeros to improve the security of the blocking network. The study included building an electronic voting system based on smart contracts using smart contracts using The decentralized private blocking technology encrypted with the ECC algorithm. The researcher recommended using servers with high specifications and increasing the number of servers in each governorate when applying them.
