Carbon checking system and method based on block chain and attribute encryption

The invention discloses a carbon checking system and method based on block chain and attribute encryption, the block chain and attribute encryption technology are combined to ensure data and access security, main carbon checking participants can realize credible interconnection by adding block chain nodes, original data are linked for evidence storage, and the authenticity of the data is effectively ensured; carbon emission, emission reports, check reports, supervision data and the like are timely collected and chained, and meanwhile, data fine-grained access control and problem data early warning processing are realized through an attribute encryption technology, so that privacy protection and accurate sharing of information are realized; traces of all data of the upper chain can be reserved, the data among the nodes are consistent and transparent, and the data traceability is realized. According to the carbon checking system and method based on the block chain and attribute encryption, the problems that in
