Based on the blockchain, homomorphic ElGamal encryption and ring signature, an electronic voting scheme based on blockchain is proposed for large-scale voting, which has the properties of decentralization, self-management, non-interactive and free-receipt, furthermore the one-time ring signature ensures the anonymity of the vote trading in the blockchain. The public verifiable billboards guarantee the voting fair, and the miner nodes provides ciphertext ballot counting service makes large-scale voting feasible. Finally, we analysis the security of the blockchain voting system and present the performance in large-scale nodes.
