In this paper, a double-blockchain structure based on “public blockchain + consortium blockchain” was proposed for the information querying of tobacco traceability system. The public blockchain adopts Ethereum platform, which can not only ensure the openness of data but also ensure data security. The consortium blockchain adopts Hyperledger Fabric platform, and only internal organizations of tobacco companies participate in setting certain permissions for tobacco companies. In addition, we also improve the consensus mechanism of the consortium blockchain and add management node to ensure the security of the consortium blockchain. The double-blockchain structure proposed in this paper can not only improve the security of querying tobacco traceability information but also not affect the efficiency of querying.
