The first embodiment is as follows:
the present disclosure provides a digital manifest management method, as shown in fig. 1.
S1 creating an organizational structure for a digital manifest system, wherein the organizational structure includes one or more bodies, each body containing one or more objects.
In one embodiment, a digital inventory system organization is shown in FIG. 2. Digital inventory systems include, but are not limited to, the following participant subjects:
a warehousing party, typically one or several professional warehousing companies (i.e. the objects);
a trading platform party, typically one or several bulk commodity exchanges or futures exchanges (i.e. the objects);
a fund provider, typically one or several banks or futures companies (i.e. the objects);
a risk controller, typically one or several insurance companies or futures companies risk management subsidiaries (i.e. the objects);
the administrator is generally one or several administrative units, such as a certificate authority, a local financial administration (i.e., the object), and the like.
In the digital warehousing system, each participant principal or object is equal and may have one or several blockchain nodes.
S2 builds a Fabric blockchain network of the digital manifest system based on the organizational structure.
In one embodiment, as shown in the Fabric blockchain network structure diagram of fig. 3, the hyper-hedger Fabric blockchain network is built according to the organization structure determined in step S1. In general, a Fabric blockchain network contains the following classes of nodes:
order node (ordering service node): receiving the transaction containing the endorsement signature, sequencing the unpacked transaction to generate a block, and broadcasting the block to the Peer node
Peer node (Peer node): each Peer node is a bookkeeping node, and besides the bookkeeping node, the Peer node can also play one to multiple roles, namely, a certain node can be a bookkeeping node and an endorsement node at the same time, and can also be a bookkeeping node, an endorsement node, a master node and an anchor node at the same time.
CA node (authentication authorization node): and receiving a registration application of the client, and returning a registration password for logging in so as to obtain the identity certificate. All operations on the blockchain network verify the identity of the user.
In the digital warehouse receipt system of the embodiment, each participant has at least one Peer node, so that each participant can obtain real-time, real and consistent warehouse receipt data.
Therefore, the Fabric blockchain network of the digital warehouse system is formed by mutually linking a plurality of Order nodes, a plurality of CA nodes and a plurality of Peer nodes of each participant.
S3 creating a data structure of the digital manifest system, the data structure including, manifest essential information data, manifest user information, manifest trade information, and manifest pledge information, wherein the manifest essential information includes manifest state information, and the manifest pledge information includes pledge state information.
In one embodiment, the data structure of the digital manifest system mainly includes the following four types:
1. warehouse bill basic information data format
2. Bill user information data format
3. Bin order transaction information data format
4. Warehouse receipt pledge information data format
In one embodiment, in the above four data, the basic information of the manifest and the user information of the manifest are completely public data for all the participants of the digital manifest system to access; the warehouse bill transaction information is only used for the access of a specified warehousing party, a transaction platform party and a monitoring party; the warehousing information is only used for access of designated warehousing parties, fund providers, risk controllers and supervisors.
S4 creating a data access policy of the digital policy system, where the policy specifically includes that the basic information of the policy and the user information of the policy are open to all cooperative objects for public data, and uplink, storage, and sharing are performed through a Channel of the Fabric block chain network; and setting different private data sets PDC in the Channel for storing the warehouse receipt transaction information or the warehouse receipt pledge information, wherein the private data sets PDC are used for uplink, storage and sharing among authorized objects in a specified range.
In one embodiment, as shown in a schematic diagram of a data access policy shown in fig. 4, in the digital policy system of this embodiment, the basic information data of the policy and the information data of the policy user are used as completely public data, and uplink, storage, and sharing are performed through a Channel of a Fabric block link network. The business trade information data and the stock pledge information data contain sensitive business confidential data, and different PDC (private data sets) are arranged in the Channel, so that uplink, storage and sharing are performed among authorized partners in a specified range.
S5 updates the pledge status information, including,
responding to a first authorized object to apply for pledge financing to a first warehouse receipt owned by a second authorized object and a third authorized object, respectively generating pledge information data of the first warehouse receipt in a first private data set and a second private data set, wherein the first authorized object is an object authorized by the first private data set and the second private data set, the second authorized object is an authorized object of the first private data, the third authorized object is an authorized object of the second private data set, and updating the pledge state information in the warehouse receipt pledge information to be a first pledge state, and at the moment, the warehouse receipt state information in the warehouse receipt basic information is a first warehouse receipt state,
and responding to the second authorized object passing through the pledge financing application before the third authorized object, updating the pledge state information in the first private data set into a second pledge state, and updating the warehouse receipt state in the warehouse receipt basic information into a second warehouse receipt state, based on the second warehouse receipt state, the third authorized object refuses to pass through the pledge financing application.
In one embodiment, for example, all the inventory basic information data and the inventory user information data of the warehousing company 1 are stored on a Channel of the Fabric network (such as named Channel-1), and all its partners (such as bank 1, bank 2, futures company 1, insurance company 1, risk management company 1, futures exchange 2, local financial bureau 1, witness party, etc.) are invited to join the Channel. Thus, all the warehouse bill basic information data and warehouse bill user information data of the warehousing company 1 are shared with all the partners joining the Channel, and all the participants can obtain real and consistent warehouse bill basic information data and warehouse bill user information data from Channel-1 through the Channel code.
On the basis, the bank 1 and the insurance company 1 are cooperative partners, the warehousing company 1 is provided with the warehouse financing service, and the local monitoring bureau 1 is a monitoring party of the financing service. Then, the 4 parties can form a sharing group on the Channel, define a private data set (named as PDC-1), store all the warehouse warranty pledge information data generated by the warehouse warranty financing service in the PDC-1, and set an access policy, and only the bank 1, the insurance company 1, the warehouse company 1 and the local administration 1 have access to and update the data in the PDC-1.
Meanwhile, the bank 2 and the insurance company 1 are also cooperative partners, and also provide the warehousing company 1 with the warehouse financing service, and the certificate prison is the supervisor of the financing business. These 4 parties can also form a shared group on the Channel defining a private data set (named PDC-2, for example). Similarly, all the warehouse receipt pledge information data generated by the bank 2 providing the warehouse receipt financing service for the warehousing company 1 are stored in the PDC-2, and the access policy of the PDC-2 is as follows: only bank 2, insurance company 1, storage company 1 and certificate authority have access to and update data in PDC-2.
When a first authorized object, for example, a user a of a warehousing company 1, applies to a second authorized object, for example, a bank 1, and a third authorized object, for example, a bank 2, respectively for a warranty financing application for a first policy, for example, a policy war-1 owned by the second authorized object, for example, the bank 1, the digital policy system of the present embodiment first generates policy warranty information data of war-1 in a first private data set, for example, PDC-1, and a second private data set, for example, PDC-2, respectively. In this case, the warrant status in the warrant pledge information data as the first pledge status may be, for example, "applying for pledge", and the warrant status in the warrant warran-1 in Channel-1 as the first warrant status may be, for example, keeping "warehoused" unchanged.
Assuming that the bank 1 and the cooperative risk controller insurance company 1 have audited the pledge application and passed the pledge audit of the policy prior to the bank 2, the pledge status of the bin elemental policy information data in PDC-1 and the policy status of the bin elemental information data in Channel-1 are both changed to "pledged". At this time, when the bank 2 checks the pledge application of the stock bill, the state of the stock bill in the Channel-1 is changed from 'warehoused' to 'pledged', and the approval condition is not met any more, so that the approval is not passed.
In this process, bank 1 and bank 2 cannot access the PDC of the other party, so neither know that user a applies for the pledge application to the same warrant warran-1 at both banks at the same time. However, through updating and acquiring the completely-disclosed basic information data of the warehouse receipt and updating and acquiring the information data in the PDC corresponding to the warehouse receipt, two banks can timely and accurately know the real state of the warehouse receipt (whether the warehouse receipt is already pledged or hung or not) and the possibility that the warehouse receipt is repeatedly pledged is avoided, meanwhile, in the whole process, the bank 1 and the bank 2 are used as competitors, the commercial secrets of the other party cannot be acquired through the digital warehouse receipt system, and the method is beneficial to protecting the privacy data of users for bank users.
By the method, the digital warehouse receipt system can ensure the authenticity and consistency of all data in the system, and also ensure the protection and specified range sharing of business confidential data and user privacy data.
In one embodiment, the aforementioned data access policies are implemented by smart contracts.
In the Fabric blockchain network, data access and modification are realized through the chaincode, so the chaincode is actually equivalent to a protocol layer of each participant, and a data access strategy agreed by each participant is realized through the chaincode, thereby ensuring that a data access mechanism is fair and consistent for all participants. A plurality of intelligent contracts can be set according to business needs, such as applying for a pledge (a flowchart is shown in fig. 5), approving a pledge (a flowchart is shown in fig. 6), applying for a hang list (a flowchart is shown in fig. 7), approving a hang list (a flowchart is shown in fig. 8), and the like.
Each participant can call the intelligent contract chaincode through the node in the Fabric blockchain network, so that the warehouse bill data can be accessed and updated. On the basis, each participant can build an independent subsystem for realizing respective unique requirements by depending on the node of the participant in the Fabric block chain, and finally, a complete digital warehouse receipt system is built, as shown in fig. 9. Meanwhile, the structure enables the data layer (Fabric block chain network) and the service layer (system application layer) of the digital warehouse system to be completely stripped, so that effective cooperation is guaranteed, and excellent expansibility is guaranteed. The digital warehouse system can add new participants, block chain nodes, data access strategies, data structures, data information, intelligent contracts and subsystems at any time.
