Encrypted electronic voting system and method based on alliance block chain technology

The invention relates to the technical field of electronic voting, and discloses an encrypted electronic voting system and method based on an alliance block chain technology, and the system comprises a member authority control management module, a voting intelligent contract module, and a distributed account book storage module. The voters and the voting initiators register the entity identities of the voters and the voting initiators through the member authority control management module to join the alliance chain network. The voting intelligent contract module is used for achieving specific encrypted voting process automation and comprises a voting party contract, a voting publisher contract and a voting result statistics and contract publishing module. The distributed account book storage module is maintained by nodes in a block chain network, adopts a Raft consensus algorithm for accounting, is public and transparent for the voting party and the voting initiator, and can carry out traceability verificatio
