E-voting System using Public Blockchain

Our paper aims at developing an online e-voting system using blockchain. It proposes the use of block chain to build an efficient and secure system for conducting elections online while using anonymity. The voter accounts are mapped to public keys of accounts on the blockchain randomly. When a vote is cast it is written to the blockchain and recorded. It cannot be modified as the blockchain is immutable. This system would ensure anonymity as there is no voter data stored on the blockchain. Since the mapping of the user accounts to the public key is not known, the votes cannot be traced to the voter. Upon completion of the election the blockchain can be made available to the public in order to verify their votes individually by providing them access to public keys. This ensures fair elections which can be conducted at any level.
