Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

FIG. 1 is a system architecture diagram 100 that may be used in embodiments of the present invention. The following embodiments may apply the system architecture to trade information processing.

As shown in fig. 1, a system architecture may include a plurality of network nodes, networks, and blockchains. Wherein:

in this embodiment, the plurality of network nodes may include a provisioning node, a platform node, a demand node, a policing node, a lending node, a financing node, a credit investigation node, a guarantee node, and other nodes. It should be understood that the number of network nodes in fig. 1 is merely illustrative. The system architecture may have any number of provisioning, platform, demand, supervisory, lending, financing, credit investigation, and vouching nodes, as desired for implementation. Wherein each network node may be a variety of electronic devices. These electronic devices include, but are not limited to, personal computers, smart phones, tablets, personal digital assistants, servers, smart appliances, smart wearable devices, and the like. These electronic devices may be installed with various messaging client applications, such as instant messaging tools, mailbox clients, social platform software, audio video software, and the like. These electronic devices may have, among other things, a memory and a logical operation processor, control elements, etc. The electronic devices can send data requests, receive data requests, analyze, retrieve, verify, store data, and the like. Generally, the server has a higher hardware configuration and a stronger computing power. In the case of less computational stress, the server may be replaced by a desktop, workstation, mobile device, or other electronic device.

In this embodiment, a network is used to provide a medium for communication links between various electronic devices. In particular, the network may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others. Each node in the network where the block chain is located is in a peer-to-peer position, and each node has the same function and has no master-slave division. Typically, individual nodes do not rely on a dedicated centralized server, nor do they have dedicated workstations. One computer can be used as a server to set up shared resources for use by other computers in the network, or as a workstation. These nodes can both act as requestors of network services and provide resources, services and content in response to requests from other computers. Typically these resources and services include: sharing and exchange of information, computing resources (e.g., CPU computing power sharing), storage sharing (e.g., use of cache and disk space), network sharing, printer sharing, and the like.

In this embodiment, the blockchain may be a technical solution for collectively maintaining (maintaining through all nodes in the blockchain) a reliable database through decentralized and untrusted manners. All nodes in the block chain have no master-slave part, and the identity positions of the nodes are consistent. Any operation done by each node can be recorded in the blockchain only after obtaining the consistent approval of other nodes, and once the data is written, the data cannot be modified. Therefore, the data recorded in the blockchain cannot be modified by the control node with a special master control position, the data recorded in the blockchain cannot be tampered, and the reliability is high.

Fig. 2 is a schematic flow chart 200 of a method of processing trade information according to a first embodiment of the present invention. This embodiment is used on the supply node side of the traded object.

As shown in fig. 2, in S201, the supply node broadcasts pending trade information in the network where the blockchain is located.

In this embodiment, the supply node may be a server, and the server may directly broadcast the pending trade information in the network where the blockchain is located. The server may be a cloud or a remote network device, including but not limited to a single network server, a set of multiple network servers, or a cloud of multiple servers. Here, the Cloud may be configured by a large number of computers or web servers based on Cloud Computing (Cloud Computing). Cloud computing is a kind of distributed computing, and is a super virtual computer composed of a group of loosely coupled computer sets. In the embodiment of the present invention, the server may implement communication through any communication method, including but not limited to, 3GPP, LTE, WIMAX based mobile communication, TCP/IP, UDP protocol based computer network communication, and bluetooth, infrared transmission standard based short-range wireless transmission.

In some alternative embodiments, the supply node may be other electronic devices shown in fig. 1, and the supply node may also broadcast the pending trade information through a platform node, such as a financial service platform.

In this embodiment, the pending trade information may include: information on the trade object for which data processing is performed. The trade object may be a specific tangible product, such as steel, oil, grain, etc., or may be an intangible trade product abstracted as digital information, which is not limited in this respect.

In S202, after the broadcasted trade information obtains the network consensus, the consensus trade information is stored in the blockchain.

In this embodiment, the network consensus may be a mechanism for verifying and agreeing on the correctness of system data such as transaction, digital record, electronic evidence, etc. by a plurality of participating network nodes in a distributed system without a central control node. The consensus can be achieved by workload certification pow (proof of work), equity certification pos (proof of stamp), and delegation equity certification DPoS (freed proof of stamp), rayleigh consensus rcp (ripple consensus), and Stellar protocol. For example, the PoW mechanism and the PoS mechanism may be mixed to make up for the deficiency of the single mechanism, so as to enhance the effect of network consensus and ensure the reliability of trade information processing.

It will be appreciated that network consensus is not an absolute consensus among all nodes in the entire network. In particular, different arrangements may be made in consideration of some actual special cases. All online nodes except the first node may be set to agree, for example, taking into account whether the node is online or not. It may also be set, for example, so long as 80% of all nodes that are online are reached for agreement. In addition, the supply node may be configured to recognize itself.

In S203, the stored trade information is subjected to maintenance processing of one or more nodes in the network in which the blockchain is located.

Two embodiments are listed below to specifically describe the implementation of the maintenance process of one or more nodes in the network where the blockchain is located.

Firstly, enumerating an implementation mode of maintaining and processing to-be-processed trade information by a supervision node in a network where a block chain is located.

S1-11: and the supervision node in the network where the block chain is located acquires the to-be-processed trade information stored in the block chain.

S1-12: the supervisory node collects recorded information associated with the acquired pending trade information.

S1-13: and based on the associated recorded information, the supervision node supervises and audits the obtained to-be-processed trade information.

In this embodiment, all information of historical trading behaviors, loan behaviors, financing behaviors, and the like of the blockchain may be queried by the supervisory node (third-party supervisory organization), so that the supervisory node can conveniently perform financial trade supervision. When the conditions of trade default, trade dispute and the like occur, the related third-party supervision mechanism can quickly find out the truth of the affair and process the affair, and the related result is included in the credit evaluation of the credit investigation mechanism. By the arrangement, the authenticity, safety and reliability of the trade information can be ensured, and the reliability of the processing of the trade information is improved.

Then, enumerating the implementation manner of the credit investigation node in the network where the blockchain is located to perform maintenance processing on the to-be-processed trade information.

S1-21: and the credit investigation node in the network of the block chain respectively sets node credit scores for one or more nodes in the network of the block chain.

S1-22: the credit investigation node acquires data information associated with one or more nodes.

S1-23: and the credit investigation node changes the node credit score of the corresponding node according to the acquired data information.

In this embodiment, the credit investigation node (credit investigation institution) can comprehensively evaluate the credit condition of the enterprise through information such as product sale records, product agency sale records, loan records, financing records and the like of the block chain. In combination with the online enterprise qualification audit, the credit investigation node can broadcast the credit investigation record and store the broadcast in the block chain for all participants to refer to. Wherein, the credit investigation record can include: credit investigation record number, enterprise name, enterprise number, enterprise credit rating result, broadcast time, credit investigation agency signature, etc.

Because the credit investigation node is equal to other nodes, the credit score of the credit investigation node is objective and fair, otherwise, the credit investigation node can release the credit investigation function due to unfair or wrong credit score. Therefore, credit scoring is carried out on the nodes in the network through the credit investigation nodes, and the node credit scores of the nodes are changed in time according to the behaviors of the nodes, so that integrity and trust of the nodes can be promoted. By the arrangement, the real, safe and reliable trade information can be ensured by objective and fair credit evaluation, and the processing reliability of the trade information is improved.

In S204, the maintained trade information is stored in the blockchain after obtaining the network consensus.

The following describes in detail an implementation of a supply node (e.g., a manufacturer, a supplier, etc.) for processing trade information by taking a tangible product as an example.

S1-31: the supply node stores the product into the warehouse, generates a product warehouse receipt record which is used as the unique identifier of the product, wherein the record comprises information such as document number, warehouse information (warehouse name, storage position and contract number), product information (product name, material, production place, production unit, quantity, weight, incoming date, quality certificate and occupied area), order opening date, delivery record, supplier signature, warehouse logistics merchant signature and the like.

S1-32: the product warehouse bill record is written into the block chain storage by the manufacturer, and the whole network consensus is obtained. At this point, the process of storing the product in the warehouse and generating the broadcast product manifest record is completed.

S1-33: the supplier directly broadcasts the information of the sold product. The supplier generates a sale record and broadcasts the sale record in a block chain, wherein the record comprises information such as a sale record number, a product warehouse bill number, a product description, a production date, a warehouse logistics merchant name, a warehouse logistics merchant number, a warehouse code, a warehouse name, a supplier number, a supplier name, a supplier tax number, a warehouse state, a transaction variety name, a transaction variety code, a customs commodity number, a product description, a specification description, a bundle number, a resource number, a warehouse area description, a warehouse location description, a production place, a material, a weight unit, a quantity, a unit price, a quality description, an appearance description, a product grade, a warehouse date, a metering mode, a packaging mode, a danger grade, a supplier signature, a warehouse logistics merchant signature and the like.

In this embodiment, the provisioning node may choose to sell the product directly to the user. In other embodiments, the provisioning node may also choose to sell the product by broadcasting the product information via an intermediary (platform node, such as an intermediary trading platform or an agent platform).

Specifically, the supplier chooses to sell the product by broadcasting the product information via an intermediary party, such as an intermediary trading platform or an agent platform. The intermediary party generally performs works such as manufacturer qualification examination, product examination, information verification and the like, generates a product agent sale record after verifying the authenticity of the product information, and then stores and broadcasts the product agent sale record in a block chain. The agent sale record information comprises a sale record number, a middle party name, a middle party code, a warehouse logistics provider name, a warehouse logistics provider number, a warehouse receipt number, a warehouse code, a warehouse name, a supplier number, a supplier name, a supplier tax number, a warehouse state, a transaction variety name, a transaction variety code, a customs commodity number, a product description, a specification description, a bundle number, a resource number, a warehouse area description, a warehouse location description, a production place, a material, a weight unit, a quantity, a unit price, a quality description, an appearance description, a product grade, a warehouse entry date, a metering mode, a packaging mode, a danger grade, a supplier signature, a warehouse logistics provider signature, a middle party signature and the like.

Fig. 3 is a schematic flow chart 300 of a method of processing trade information according to a second embodiment of the present invention. This embodiment is used on the demand node side of the trade object.

As shown in fig. 3, in S301, the demand node acquires pending trade information.

In S302, the demand node acquires the recognized trade information and/or the maintenance-processed trade information corresponding to the pending trade information from the blockchain.

It is to be understood that the term "and/or" herein is merely one type of association relationship describing an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone.

In S303, the demand node compares the acquired recognized trade information and/or the maintenance-processed trade information with the acquired pending trade information, respectively.

In S304, the demand node sends trade feedback when the obtained agreed and/or maintenance processed trade information respectively matches the obtained pending trade information.

The main differences between this embodiment and the embodiment shown in fig. 2 are: the method shown in the embodiment is applied to the demand node side of the trade object, while the embodiment shown in fig. 2 is applied to the supply node side, which are different in the described angle, but similar in the working principle or the details of the method. For brevity, the same or similar contents are not described in detail, and the descriptions of the contents of the embodiments may be referred to each other.

The following describes the implementation of the maintenance process in the embodiment shown in fig. 3 by way of example in four embodiments.

S2-11: and the supervision node in the network where the block chain is located acquires the to-be-processed trade information stored in the block chain.

S2-12: the supervisory node collects recorded information associated with the acquired pending trade information.

S2-13: and based on the associated recorded information, the supervision node supervises and audits the obtained to-be-processed trade information.

This example is similar to the embodiment shown in fig. 2, except that this embodiment is applied to the demand node side, and the embodiment shown in fig. 2 is applied to the supply node side, and the details can refer to what is described above.

Then, the implementation manner of performing maintenance processing on the to-be-processed trade information by credit investigation in the network where the blockchain is located is listed.

S2-21: and the credit investigation node in the network of the block chain sets node credit scores for one or more nodes in the network of the block chain.

S2-22: a correspondent node obtains data information associated with one or more nodes.

S2-23: and the credit investigation node changes the node credit score of the corresponding node according to the acquired data information.

This example is also similar to the embodiment shown in fig. 2, except that this embodiment is used on the demand node side, while the embodiment shown in fig. 2 is applied on the supply node side, and the details can also refer to what is described above.

Then, an implementation manner in which the demand node performs maintenance processing such as trade data is listed.

S2-31: the demand node sends a preset number of trade data requests in the network where the block chain is located.

S2-32: after the loan and/or financing request has been agreed upon by the network, the agreed upon trade data request is stored in the blockchain.

S2-33: the demand node obtains a trade data response after the stored debit and/or financing request passes the audit of the trade data nodes in the network where the blockchain is located. Wherein the preset number is associated with a current node credit score of the demand node.

It is understood that in the financial trading process, trading activities may occur directly by the buyer, the intermediary party, and the supplier. In addition, the demander node and the provider node may also perform a trading action through the intermediate node, for example, the demander node provides a document to the intermediate node, and the intermediate node performs a corresponding trading action according to the document.

Specifically, a buyer, an intermediate party and a supplier can trade by means of a block chain, a demander needs to submit materials such as qualification certification and the like to a trading mechanism, the trading mechanism can inquire information such as historical trade records and credit investigation records of the demander by means of the block chain, if qualification audit on the demander is passed, the trading mechanism agrees to provide trade data for an enterprise, a trade record is generated, and broadcasting is stored in the block chain. The trade record includes information such as record number, enterprise name, enterprise number, financial institution name, financial institution number, amount of money, term, liability of default, enterprise signature, trade institution signature, etc. When the trade process is completed, a trade record is generated and the broadcast is stored in the blockchain. The trade record comprises information such as a record number, an enterprise name, an enterprise number, a trade organization name, a trade organization number, a quantity, a time, an enterprise signature and a trade organization signature.

In addition, the demand side, the intermediate side and the supply side can broadcast the data processing plan by the block chain, and the broadcasting of the data processing plan can be independently completed or completed under the guarantee of the trade institution. The financial plan broadcaster need only generate one data processing record and store the broadcast in the blockchain. The data processing record includes information such as a record number, a broadcaster name, a broadcaster number, content, a reward, a broadcast date, a schedule term, a warranty agency signature, a broadcaster signature, etc.

Therefore, the embodiment can promote safe and reliable trade execution and improve the feeling of users by providing the trade data processing service.

Finally, an implementation manner of maintenance processing such as warranty performed by the demand node (purchaser) is described.

S2-41: the demand node sends a predetermined number of guarantee requests in the network in which the blockchain is located.

S2-42: after the transmitted vouching request obtains the network consensus, the consensus vouching request is stored in the blockchain.

S2-43: after the stored guarantee request passes the examination of the loan node in the network where the blockchain is located, the demand node obtains a guarantee response. Wherein the preset number is associated with a current node credit score of the demand node.

Specifically, the guarantee agency can inquire the historical records, guarantee records, data processing records and credit investigation record information of the purchaser through the block chain, and completes the qualification auditing process of the demander by combining with the investigation and confirmation of the off-line enterprise qualification information. If the vouching authority agrees to offer a vouch-for to the enterprise, a vouch-for record is generated and the broadcast is stored in the blockchain. The guarantee record comprises information such as a guarantee record number, an enterprise name, an enterprise number, a guarantee agency name, a guarantee agency number, a guarantee range, guarantee contents, a guarantee mode, a guarantee period, a guarantee agency responsibility, a default responsibility, a guarantee agency signature and the like.

Therefore, in the embodiment, by incorporating the guaranty service record of the guaranty organization into the blockchain, the problem that some small enterprises may not meet the requirements of product manufacturers or intermediaries due to problems of capital, enterprise qualification and the like in the purchasing process, and thus the guaranty service is needed can be solved. Therefore, the embodiment can promote safe and reliable trade execution and improve the feeling of the user by providing the guarantee service.

The following describes an implementation of a demand node (e.g., a buyer) for processing trade information in detail by taking a tangible product as an example. The purchaser may choose to purchase the product directly to a provisioning node (e.g., a manufacturer) or via an intermediary platform.

S2-51: the buyer queries the blockchain for product sales records and then contacts the supplier for offline on-site product exploration if deemed necessary.

S2-52: after the authenticity of the product information and the inventory state of the product are verified and the purchasing intention is reached, the purchasing party pays the supplier, and appoints the purchasing affairs such as the delivery date, the default responsibility and the like.

S2-53: the method comprises the steps that a purchaser, a supplier and a storage logistics merchant jointly create a product purchase record, common identification broadcasting is stored in a block chain, and the product purchase record comprises record numbers, a warehouse order number, a goods total amount, a goods selling amount, a warehouse name, a storage position, a goods production date, a goods warehousing date, a transaction date, a goods deliverer, a goods description, an agreed delivery date, default responsibility, a purchaser signature, a supplier signature, a storage logistics merchant signature and other information.

S2-54: the method comprises the steps that a purchaser can complete off-line goods picking by virtue of a product purchase record, after goods picking is completed, the purchaser and a storage logistics provider jointly broadcast a product goods picking record and store a consensus broadcast in a block chain, wherein the record comprises information such as a goods picking record number, a purchase record number, a goods delivery amount, a goods delivery position, a goods delivery time, a goods deliverer, a product number, a product quantity, a product description, a goods delivery mechanism signature and a storage logistics provider signature.
