However, the coding method, the tracing system and the data supervision in the existing tracing system often run independently, enterprises fight each other, information intercommunication interconnection is lacked, coding is inconsistent, and data is opaque, so that the tracing system is not standard, upstream and downstream data are incompatible, and an 'information island' is formed, which causes tracing difficulty. Once an enterprise joins the tracing network, a supervision system is difficult to realize fine-grained management and control, data on a chain cannot be effectively supervised, once a safety responsibility accident occurs, responsibility accurate positioning and product accurate tracing are difficult to perform, a problem product is recalled in time, and real-time supervision on a supply network cannot be achieved. Therefore, breaking the information barrier and making the various modules of the supply network form a good interaction is urgent. The existing research on the information intercommunication and interconnection is relatively deficient, and the tracing information control mainly comprises the following two schemes:
one scheme is that source data is stored in a down-link mode, a plaintext information abstract chain is stored in a certificate, authenticity of data is verified through cooperation of the up-link and the down-link, storage capacity is increased, however, if the down-link data is tampered, the data is difficult to recover, the risk of real data loss exists, on the other hand, all product information is uploaded to a block chain by an enterprise, and privacy information is easy to leak; the code and the data storage run independently, and illegal modification, cracking or batch counterfeiting of the tracing code inside or outside can cause chain breakage between upstream and downstream enterprises.
The other scheme is that the plaintext of public data is uploaded to a public traceability chain, private data is uploaded to an enterprise private chain in an encrypted mode and authorized to be shared, so that the capacity of a block chain can be increased, the data on the chain cannot be tampered, when a safety liability accident occurs to a product, a supervision department can determine a problem link through traceability private data, but cannot achieve penetrating whole-course supervision, and real-time full-coverage monitoring is achieved.

s21, obtaining a tracing code based on the Key value;
s22, calling a tracing contract based on the tracing code, and inquiring a alliance chain to obtain public tracing information;
and S23, calling a cross-link contract based on the source tracing code, and inquiring the private chain to obtain private privacy information.
Optionally, the traceable code is used as a Key value, an enterprise creates a state index database Key value index in a Key-value Key value pair mode, traditional traversal query is replaced, query speed is improved, the coded Key value is written into a supervision chain, and a supervision node queries the latest state of a Key value through the world state index, so that real-time monitoring is achieved.

and 31, encrypting the private privacy information in the enterprise tracing data meeting the uplink requirement, and writing the private privacy information into the private chain.
Optionally, as shown in fig. 4, firstly, the enterprise tracing data passes through a data-structured intelligent contract (including a plaintext data cochain contract and a ciphertext data cochain contract), determines whether the data content and format meet the cochain requirement, and rejects if not, uploads the data content and format to the block chain through the cochain contract (including a production data cochain contract, a processing data cochain contract, a storage data cochain contract, a logistics data cochain contract, and a distribution data cochain contract) for the enterprise tracing data meeting the requirement, and generates a unique traceability code, for the public tracing information in the enterprise tracing data, after passing through the data-structured intelligent contract, the public tracing information can be written into the block chain, for the private privacy information in the enterprise tracing data, after passing through the data intelligent contract, the encrypted private information is encrypted through the encrypted intelligent contract submitted by the node, and then the ciphertext is written into the private chain of each stage, to ensure the safety and privacy of private privacy information.
The tracing code is used as a Key value, an enterprise creates a state index database Key value index in a Key-value Key value pair mode to replace the traditional traversal query, the query speed is improved, the code Key value is written into a supervision chain, and a supervision node queries the latest state of a Key value through the world state index so as to achieve real-time monitoring. In the data storage, large data in a fluid form, video pictures and the like are stored in a distributed mode under a chain by using an Interplanetary file system (IPFS), and source tracing data are stored in a key value pair mode by using a CouchDB state index database providing rich query.
The traceability information of each stage of the agricultural product takes traceability codes as Key values, the product information is value values, and the traceability information is stored in a CouchDB state index database providing rich query in a Key-value Key value pair mode. And the consumers scan the final tracing two-dimension code to obtain the tracing code Key value of the product at each stage, so that the product information is quickly obtained.
