An electricity blockchain based on smart contract is designed by introducing decentralization into smart grid in this paper. The data in blockchain may reveal user privacy due to transparency. Therefore, a blockchain privacy protection scheme based on additive homomorphic encryption algorithm is proposed. The electricity and account balance of users are encrypted by the homomorphic encryption algorithm in the scheme to realize the confidentiality of data ensuring electricity billing. Finally, the security of the scheme is proved and the performance of the scheme is analyzed. The encryption algorithm of the scheme has less computational complexity and higher efficiency.
