Description: This article is devoted to development of electronic voting system based on the blockchain technology. Voting is the bridge between the governed and government. The current voting system has many security holes, and it is difficult to prove even simple security properties about them. There are also some reasons for a government to use electronic voting systems are to increase elections activities and to reduce the elections expenses. This article provides an overview of the experiences of other countries using electronic voting systems. Disadvantages of existing electronic voting systems were analyzed in this paper. Fundamentally new open source electronic voting system was supposed based on the analysis of existing electronic voting systems. Supposed electronic voting system uses blockchain for saving electronic votes on devices of voters. A blockchain is a decentralized, distributed and public digital ledger that is used to record transactions across many computers so that any involved record cannot be altered retroactively, without the alteration of all subsequent blocks. Each block of blockchain contains a cryptographic hash of the previous block, a timestamp, and transaction data. By design, a blockchain is resistant to modification of the data. Using of blockchain guarantees immutability of votes. This system allows voter to vote remotely using his own smartphone, tablet or personal computer and verify immutability of his vote. Voting secret is also guaranteed by this proposed electronic voting system. Main threats to the proposed electronic voting system were investigated. Investigation of these threats allows to design protected electronic voting system. Implementation of proposed electronic voting system will allow to increase legitimacy of elections, involve more voters to take participation in the elections.
