It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present description. The word "if," as used herein, may be interpreted as "at … …" or "when … …" or "in response to a determination," depending on the context.

Currently, some physical goods may be temporarily stored in the warehouse of the warehousing party, and a storage certificate returned by the warehousing party is obtained, and the storage certificate may be regarded as the code number of the physical goods. For convenience of the following description, such a storage certificate is referred to as a manifest, and an organization or an individual storing physical goods at a warehousing party is referred to as a depositor. The information of the stock party identifier, the storage party identifier, the type of the stored physical goods, the quantity of the stored physical goods, the value and the like can be recorded in the warehouse bill.

The depositor may transfer the inventory to the resource side in exchange for the resource matching the value of the inventory, and it is understood that the transfer of the inventory to the resource side in exchange for the resource matching the value of the inventory may be a transfer of some right to the resource side to obtain some right to the resource matching the value of the inventory. E.g., ownership, etc. The right of the depositor to the resource is only temporarily owned and is not permanently owned, and the right of the depositor to the warehouse is also temporarily owned. If certain conditions are met, the right of the resource needs to be returned to the resource side, and the right of the warehouse bill is retrieved, for example, if the time length agreed by the two sides is reached, the right of the resource is returned to the resource side by the stock side.

In general, the stocking party needs to return the acquired right of the resource to the resource party according to the agreement with the resource party, wherein the agreement can also agree with the return time and the number of the resource needing to be returned more, namely the stocking party usually needs to return a part of the resource when returning the right of the resource. After returning the resource rights, the inventory party may retrieve the right to the manifest and use the manifest to retrieve the physical goods stored at the warehousing party from the warehousing party.

Fig. 1a is an interactive flowchart between the three parties, in which the process of exchanging the right of the warehousing party for the right of the resource by using the right of the warehouse slip in the diagram may be slightly different from that shown in the diagram, for example, after the warehousing party generates the warehouse slip, the warehousing party directly sends the right of the warehouse slip to the resource party, and the resource party provides the right of the resource to the warehousing party, that is, the right of the resource matching the value of the warehouse slip is issued to the warehousing party.

Wherein, there are multiple interactive processes in the above-mentioned course, if any one is done badly, will cause the serious influence to the whole business process, for example after the depositor gets the resource, does not admit to reach the exchange consensus with the resource side, refuse to transfer the bill right to the resource side; for another example, the resource party refuses to return the originally agreed right of the resource to the stocking party after obtaining the right of the warehouse of the stocking party, and the like, and the warehousing party does not return the right of the corresponding warehouse after storing the physical goods of the stocking party. I.e. there is a potential for any one party to do harm and no one party can fully trust each other.

In order to solve the above problem, the event that the inventory side uses the warehouse right to replace the resource right from the resource side can be stored in the block chain network, so that the problems of repudiation and repudiation of any one of the three sides can be avoided.

The above events may be recorded by recording each warehouse slip with the tenant transition on the blockchain network. In addition, each bin may be recorded, i.e., the bin whether or not the tenant switch has occurred is recorded on the blockchain, e.g., events characterizing each bin generation process may also be recorded in the blockchain network.

For more detailed management of each warehouse slip, the blockchain network may also manage each warehouse slip based on the intelligent contract, for example, when the warehousing party generates a warehouse slip, the warehousing party may also send a request to the blockchain network, the blockchain network may invoke the intelligent contract to issue a warehouse slip, the issued slip is an asset in the blockchain network, and the issued slip may include various information of the slip, for example, information of an possessor, a current state, whether the slip has been exchanged for a resource, and the like.

By adopting the mode, the trust problem among the stocking party, the warehousing party and the resource party can be solved, namely, the interactive data among the three parties are recorded on the block chain network, so that any party can be prevented from doing repudiation or repudiation.

In some cases, the inventory party may need to use the physical goods corresponding to the manifest before the time for the appointment to return the resources comes, but may not return sufficient resources to the resource party due to insufficient resources.

For example, the physical goods corresponding to the manifest have a shelf life, and the inventory party needs to take the physical goods corresponding to the manifest out of the warehousing party and process them as soon as possible, but not enough resources are returned to the resource party in exchange for the right to take the manifest.

For another example, in a case where the current value of the physical good corresponding to the manifest is greatly different from the value of the physical good when the resource is exchanged for the physical good, the stocking party usually wants to retrieve the physical good corresponding to the manifest as soon as possible.

On the other hand, in a situation where the current value of the physical goods is increased more, it is generally desirable for the depositor to replace the physical goods corresponding to the invoice as soon as possible, so as to obtain more resources by using the physical goods as soon as possible, for example, the physical goods corresponding to the invoice can be sold or replaced with the invoice with higher value after being replaced.

On the other hand, when the current value of the physical goods is much reduced and there is a continuous trend of decline, it is generally desired that the depositor replace the physical goods corresponding to the manifest and sell the physical goods as soon as possible to stop damage as soon as possible.

In the above scenarios, the warehousing party needs to obtain the entity goods corresponding to the manifest before the time for agreeing to return the resources comes, but in these scenarios, if the warehousing party does not have enough resources to return to the resource party, the right of the manifest cannot be exchanged, and further the entity goods corresponding to the manifest cannot be obtained from the warehousing party.

To address this problem, a "swap" approach is currently proposed that allows the inventory party to swap orders with the rights of other orders. For example, the stocking party stores some physical goods in the warehouse of the warehousing party, and obtains a target manifest with which the stocking party replaces the resource from the resource party for a resource that matches the value of the target manifest, and contracts the date on which the resource is returned.

Before the predetermined return date, the stocking side needs to acquire the physical goods corresponding to the target manifest for some reason, and thus needs to return the resource to the resource side. However, since the stocking party does not have enough resource elements to return, the stocking party can store some physical goods to the warehousing party to obtain a new warehouse slip, which is referred to as a replacement warehouse slip for convenience of description. The depositor can replace the target manifest by using the replacement manifest, that is, the corresponding entity goods in the target manifest are replaced by using the entity goods corresponding to the replacement manifest, so as to obtain the entity goods of the target manifest for processing.

The specific interactive process may be as shown in fig. 1b, where the category of the first physical goods stored by the inventory party may be the same as or different from that of the second physical goods, and this specification does not limit this. In the process of replacing the target inventory by using the replacement inventory, the resource side needs to check whether the value of the replacement inventory is matched with the value of the target inventory, and it can be understood that the matching means that the value of the replacement inventory is not lower than the value of the target inventory, so that the stocking side is allowed to replace the right of ownership of the target inventory by using the right of ownership of the replacement inventory.

In this scenario, there is still a trust issue between the inventory, warehousing, and resource parties described above, so the interaction flow of replacing the target manifest with the replacement manifest can be recorded in the blockchain website to avoid any party's repudiation or repudiation.

Based on the above description, the present specification proposes a block chain-based warehouse slip processing method applied to a warehouse slip processing system, as shown in fig. 2, the warehouse slip processing system at least includes a block chain network 210 and an inventory side client 220.

The block chain network is a distributed shared account book and a database, and has the characteristics of decentralization, no tampering, whole-course trace marking, traceability, collective maintenance, openness and transparency and the like, so that the data is stored in the block chain network, and the safety of the data can be effectively ensured. Specifically, the network may be a public link network or a alliance link network, which is not limited in this specification. When the blockchain network is an alliance-chain network, the warehousing party and the resource party may be nodes in the alliance-chain network or users of the nodes in the alliance-chain network, and the description does not limit the nodes.

The block chain network is deployed with a warehouse receipt replacement contract, the warehouse receipt replacement contract is used for processing a transaction representing a warehouse receipt replacement application event, and a processing result is stored in the block chain network; the intelligent contract can be understood as a computer program which is agreed by each party and can execute a certain transaction, and the intelligent contract is stored and deployed in the block chain network, so that the intelligent contract is not tampered and is completely trusted.

As shown in fig. 4, an interactive flowchart for executing a policy replacement proposed in the present specification specifically includes the following process steps:

s301, the inventory side client submits a transaction for calling the inventory replacement contract to the block chain network;

wherein the transaction specifies the business input information required when invoking the manifest replacement contract: target manifest identification, replacement manifest identification;

the transaction may be submitted to the blockchain network when the inventory party needs to apply for the right to replace the manifest in exchange for the target manifest right. Since the smart contract corresponds to a program that can be executed based on input information, the inventory party can add target manifest identifications and substitute manifest identifications in the transaction to invoke the smart contract to process based on the input information. Namely, the inventory side client side constructs the warehouse slip replacement application event as a transaction and submits the transaction to the block chain network to call the intelligent contract for processing each time the warehouse slip replacement application is required.

In addition, in this specification, when a warehousing party creates a bill, a unique identifier is assigned to each bill to identify and distinguish different bills. For example, the warehousing party may generate a number of each warehouse slip according to the generation sequence of each warehouse slip, and the number is used as the identifier of each warehouse slip to distinguish different warehouse slips. That is, the above replacement manifest identifier is information for identifying a replacement manifest, and the above target manifest identifier is information for identifying a target manifest.

Of course, in the case where the block chain network issues the manifest based on the intelligent contract, the intelligent contract may write the manifest identifier in the information of the issued manifest according to the manifest identifier provided by the warehousing party.

S303, the block chain network executes the warehouse bill replacement contract, matches the warehouse bill information identified by the stock square target warehouse bill, and uses the right of the replacement warehouse bill to replace the right of at least part of the matched target warehouse bill;

in this step, after receiving the transaction, the blockchain network executes a policy replacement contract to process, where the matching generally refers to searching for a target policy issued or stored in advance in the blockchain network, that is, searching for pre-stored policy information of the target policy according to a target policy identifier. Further using the right of the replacement manifest to exchange at least part of the right of the matched target manifest, specifically, removing the association relationship between the resource party and the target manifest, removing the association relationship between the stock party and the replacement manifest, and establishing the association relationship between the resource party and the replacement manifest; meanwhile, under the condition of replacing the right of all the matched target inventory, establishing the incidence relation between the depositor and the target inventory; and under the condition of exchanging partial rights of the matched target warehouse slip, splitting the target warehouse slip into a exchanged partial warehouse slip and an undischanged partial warehouse slip, establishing an association relationship between the depositor and the exchanged partial warehouse slip, and establishing an association relationship between the resource supplier and the undischanged partial warehouse slip.

As can be seen from the above description, when an inventory party submits a transaction that invokes the manifest replacement contract, it is generally because and the inventory party has replaced the rights of the target manifest to the resource party for the rights of the corresponding resource. In order to make the process credible, the process may be stored in the blockchain, and a specific way may be that the intelligent contract for exchanging the warehouse list is also used for processing the transaction representing the event of applying for transferring the warehouse list, and a specific way may be that the inventory side submits the transaction representing the event of applying for transferring the warehouse list to the blockchain network, and the transaction also calls the intelligent contract for exchanging the warehouse list. The transaction may include an identification of the target inventory. A blockchain network that can transfer the right of the target manifest of the depositor to a resource side; here, the association relationship between the depositor and the target manifest may be released, and the association relationship between the resource depositor and the target manifest may be established. Meanwhile, the resource side can transfer the right of the resource matched with the value of the target warehouse slip to the stocking side, and upload the resource quantity and the transfer result to the block chain network for storage, and the corresponding intelligent contract can record the corresponding resource and the exchanged state in the target warehouse slip.

In the above process, it is understood that the stocking party has negotiated with the resource party in advance, and the resource party and the agreement that the stocking party can use the right of the replacement manifest to replace the target manifest, so that the blockchain network can execute the said manifest replacement contract to implement the above process of directly using the right of the replacement manifest to replace at least part of the right of the matched target manifest.

However, in the event that the inventory party does not have pre-negotiated with the resource party, an audit is typically required by the resource party, i.e., it is required to determine whether to agree that the inventory party may use the rights to replace the manifest to replace the target manifest.

Thus, as shown in fig. 3, a resource side client 230 may also be included in the manifest processing system; as shown in fig. 5, before trading rights for at least part of the matched target manifest in executing the intelligent contract in the blockchain network, the method may further include:

s302a, after monitoring the policy replacement application event, the resource side client acquires the target policy identifier and the replacement policy identifier from the block chain network, and provides the target policy identifier and the replacement policy identifier to the resource side to check whether the target policy and the replacement policy are matched in value;

in this case, the inventory party actively contacts the resource party outside the blockchain network, so that the resource party acquires the target manifest identification and the replacement manifest identification from the blockchain network by using the resource party client.

The client of the resource side may also obtain the target policy identifier and the replacement policy identifier from the blockchain network when monitoring that the blockchain network executes the policy replacement contract.

After obtaining the target manifest identification and the replacement manifest identification, the resource side client can display the obtained target manifest identification information and the replacement manifest identification information to the resource side user, and the resource side user obtains the corresponding target manifest and the replacement manifest information according to the obtained two manifest identifications, and further verifies whether the target manifest and the replacement manifest are matched in value according to the manifest replacement application event, the obtained target manifest and the replacement manifest information. When the stocking side needs to replace all rights of the target warehouse slip by using the replacement warehouse slip right, whether the value of the replacement warehouse slip is larger than or equal to the value of the target warehouse slip can be audited, if so, the audited result is passed, and if not, the audited result is not passed if the value of the replacement warehouse slip is determined to be not enough to replace the target warehouse slip.

If the stock side needs to use the replacement policy to replace the partial ownership of the target policy, whether the value of the replacement policy is greater than or equal to the value of the partial ownership of the target policy which needs to be replaced or not can be checked, if so, the checking result is passed, and if not, the checking result is not passed.

Of course, it is to be understood that information as to whether an inventory party has full or partial ownership of a replacement inventory replacement target inventory using the replacement inventory rights may also be recorded in the transaction characterizing the inventory replacement application event. After the resource side completes the audit, the resource side can input the audit result through the client of the resource side, that is, the resource side client can receive the audit result input by the resource side.

S302b, responding to the operation of the resource side, the client side of the resource side submits the trade for calling the stock exchange contract to the block chain network, and the first checking result of the resource side is appointed in the trade initiated by the client side of the resource side;

after receiving the audit result of the resource party, the resource party client can construct the audit result as a first audit transaction and submit the first audit transaction to the block chain network, so that the audit result can be stored in the block chain network, and the resource party is prevented from doing harm, for example, the audit result is not admitted.

Correspondingly, S303, the right of the matched target policy can be replaced with the right of the replacement policy based on the first examination result of the resource side for the blockchain network.

In addition, in this step, the intelligent contract may be called by the block chain network, and according to the first audit transaction, under the condition that the resource party audit result representation is determined to pass, the association relationship between the resource party and the target manifest is released, the association relationship between the depositor and the replacement manifest is released, and the association relationship between the resource party and the replacement manifest is established. In addition, if the resource side does not verify the result representation, recording a record of which the verification is not passed for the target warehouse slip.

In this embodiment, when the inventory party and the resource party do not negotiate in advance, the auditing and the auditing results are stored in the blockchain network, so as to further improve the overall credibility.

By adopting the mode, the block chain network processes the transaction representing the warehouse receipt replacement application event based on the deployed intelligent contract, namely the whole process of warehouse receipt replacement is recorded in the block chain network, so that the interactive data among the stock party, the storage party and the resource party can be credible, and the trust problem among the three parties is further solved; meanwhile, since the stocking side can exchange the ownership of the target inventory with the ownership of the replacement inventory, the stocking side can be made available to exchange the physical goods in the target inventory with other physical goods.

It can be understood that the blockchain network may receive the transactions for characterizing the policy replacement event at the same time, where the above manner may be performed for the processing flow of each transaction, and in addition, in order to distinguish and characterize the transactions of different policy replacement events, the different transactions may be distinguished by using corresponding identifiers, for example, the identifiers of the target policy and the replacement policy corresponding to the different policy replacement events may be used as the identifiers of the different transactions for distinguishing, or a predefined identifier generation rule may be used to generate the identifier of each transaction for distinguishing the different policy replacement transactions, and the identifier of the policy replacement transaction is not limited in this specification.

In addition, there may be a plurality of stocking parties and a plurality of warehousing parties in the system, and the description of the business processes of a single stocking party and a single warehousing party is provided herein, it will be understood that the processes therein may be applied to each stocking or warehousing party in the system.

In order to improve the auditing rigor in the manifest replacement process, an auditing link of the warehousing party may also be added in the auditing process, that is, as shown in fig. 6, the manifest processing system further includes a warehousing party client 240.

And after monitoring the manifest replacement application event, the client of the warehousing party acquires the target manifest identifier and the replacement manifest identifier from the block chain network and provides the target manifest identifier and the replacement manifest identifier for the warehousing party for auditing, wherein the auditing can be in various modes.

Wherein, a storage side's auditing mode can be:

the storage party client acquires a target manifest identifier and a replacement manifest identifier and provides the target manifest identifier and the replacement manifest identifier to the storage party so that the storage party can check whether the target manifest and the replacement manifest are matched in value or not;

the warehousing party client submits a second examination result to the block chain network; and the second auditing result comprises a warehouse party auditing result.

The auditing manner, i.e. the specific judgment principle, may refer to the auditing process of the resource side, and is not described in detail here. The client of the storage party checks the value matching of the two bills, so that the storage party can also participate in the checking link, and the checking result can be referred to the resource party.

In addition, the warehousing party is used as a party for storing the physical goods of the stock storing party, and the storage condition of the physical goods corresponding to the warehouse slip can be checked at any time. Therefore, another auditing mode of the warehousing party can also be as follows:

the client of the warehousing party acquires the replacement manifest identification and provides the replacement manifest identification for the warehousing party so that the warehousing party can check whether the replacement manifest is real or not; the warehousing party client submits a second checking result to the block chain network; the second auditing result comprises a warehousing party auditing result. Namely, the client of the warehousing party provides the replacement manifest identification in the manifest replacement transaction to the warehousing party, and the warehousing party checks whether the entity goods corresponding to the replacement manifest exist in the warehouse or not according to the identification, if so, the audit is passed, and if not, the audit is not passed. Meanwhile, the client of the warehousing party can also provide the target manifest identification in the manifest replacement transaction for the warehousing party, and the warehousing party checks whether the entity goods corresponding to the target manifest exist in the warehouse or not according to the identification, if so, the audit is passed, and if not, the audit is not passed, namely, the authenticity of the target manifest is also audited.

In addition, if other detailed information about the manifest is stored in the manifest replacement transaction, for example, information such as the storage location, the stock quantity, the value of the physical goods corresponding to the replacement manifest, the storage location, the stock quantity, the value of the physical goods corresponding to the target manifest, and the like, the warehousing party can also perform authenticity verification on the detailed information about the target manifest and the replacement manifest stored in the replacement transaction according to the actual situation in this link.

The mode of verifying the authenticity of the warehouse bill by the warehousing party is added, so that the safety of the whole process can be further improved.

It is contemplated that if a replacement manifest succeeds in replacing the target manifest, it may involve transferring the physical goods corresponding to the replacement manifest to the actual storage location. For example, from one warehouse to another. In this process, additional costs may arise due to the need to transfer storage locations. While the transfer of storage locations is typically managed and handled by the warehousing party.

The warehousing party may not transfer the physical goods corresponding to the replacement manifest to the actual storage location for some objective reasons, for example, the physical goods may not be transferred to the actual storage location temporarily due to reasons such as traffic, weather, etc., or the warehousing party may not be able to transfer the physical goods to the actual storage location due to the extra cost generated by transportation and the expense generated by transportation due to the fact that the warehousing party cannot bear the cost.

Therefore, the auditing mode of the warehousing party can also be that the warehousing party is added to audit whether the replacement of the storage position of the entity goods corresponding to the replacement manifest is allowed.

Specifically, the client of the warehousing party acquires the replacement manifest identifier and provides the replacement manifest identifier to the warehousing party, so that the warehousing party can check whether the warehousing position of the entity goods corresponding to the replacement manifest is allowed to be transferred or not;

the warehousing party client can submit a second examination result to the block chain network; the second examination result comprises a warehouse party examination result.

When the warehousing party actually checks, it can be determined whether the current objective condition supports the transfer of the warehousing position of the entity goods corresponding to the change manifest.

For example, it may be determined that the audit is passed when the stock direction itself pays the cost of transferring the physical goods corresponding to the replacement manifest to the actual storage location, and the factors such as traffic and weather allow, otherwise the audit is not passed.

Or the warehousing party can determine whether to be willing to pay the cost according to the number of the actual cost although the cost is produced, if the warehousing party is willing, and under the condition that factors such as traffic, weather and the like also allow, the auditing is passed, if the warehousing party is unwilling, and under the condition that the warehousing party does not pay the cost, the auditing is determined not to be passed, and the like. The present specification does not limit the auditing conditions for auditing whether the transfer of the storage location is permitted.

It is understood that the warehousing party may perform all or part of the above auditing methods, and the specification should not be limited thereto.

The warehousing party client can respond to the operation of the warehousing party and submit the transaction for calling the warehousing party replacement contract to the block chain network, and the second auditing result of the warehousing party is appointed in the transaction initiated by the resource party client.

Accordingly, the blockchain network may replace at least a portion of the rights of the matched target manifest with the rights of the replacement manifest based on the first review result of the resource side and the second review result of the warehousing side.

The audit executed by the storage party can be performed before the audit of the resource party, after the audit of the resource party, or can be performed in parallel with the resource party, that is, the audit is performed by the storage party and the resource party respectively, and the two parties do not affect each other.

Finally, the warehouse policy replacement request provided by the current warehouse side can be forbidden under the condition that the audit of either the warehouse side or the resource side is not passed.

In addition, considering that the resource side is the side which finally transfers the right of ownership of the resource to the depositor, the auditing result can be the final confirmation result, namely, the auditing of the depositor can be performed before the auditing of the resource side.

As shown in fig. 7, one possible way may be that a blockchain network invokes the intelligent contract, and notifies the resource side client of a policy replacement application event when it is determined that the storage side audit result representation passes according to the second audit transaction.

The block chain network calls an intelligent contract, the warehousing party client is informed of the warehouse replacement application event, the warehousing party performs audit, the resource party client is informed after the audit of the warehousing party is passed, and the resource party performs audit again.

And the resource party is used as a party with the right of ownership of the target warehouse slip, is a final auditing party of the warehouse slip replacement application event, and further audits after the auditing of the warehouse party is determined to be passed, and if the auditing of the warehouse party is not passed, the auditing is not required. By adopting the mode, the system resource is saved, and meanwhile, the auditing efficiency is also improved.

In the case where the stocking party does not want to replace all the physical goods corresponding to the target manifest with the replacement manifest, that is, does not want all the ownership of the target manifest, the transaction-specific business information submitted by the stocking party may further include the replacement quantity, that is, the quantity of the goods that need to be replaced from the physical goods corresponding to the target manifest with the replacement manifest.

In this way, the intelligent contract is called in the block chain network, after the bill replacement application event is notified to the resource side client according to the bill replacement transaction, the resource side client can acquire the quantity of the replacement goods from the block chain network and provide the quantity of the replacement goods to the resource side, the resource side can judge whether the goods of the quantity of the replacement goods in all the goods corresponding to the target bill are matched with the value of the replacement bill, if so, the audit is passed, if not, the audit is not passed, the matching principle can be that the value of the replacement bill is greater than or equal to the value of the goods of the quantity of the replacement goods in all the goods corresponding to the target bill, the matching is performed, and if not, the matching is not performed.

In addition, in order to avoid performing the above replacement process, other process flows may also process each target inventory and replacement inventory at the same time, for example, the process flow of returning the resource to the resource side to change the ownership of the target inventory may be processed at the same time.

Therefore, when receiving the inventory replacement transaction submitted by the inventory side client, the blockchain network can put the target inventory identification and the replacement inventory corresponding to the replacement inventory identification in the inventory replacement transaction into the frozen state based on the intelligent contract, and in the case of putting the target inventory and the replacement inventory into the frozen state, the blockchain network refuses to call the inventory replacement intelligent contract for other transactions of the target inventory, wherein the other transactions are transactions unrelated to the inventory replacement application event. That is, when the intelligent contract executes the replacement transaction, other processing is not executed on the target inventory or the replacement inventory at the same time, so that the problem of data confusion caused by the simultaneous multi-service processing of each inventory is avoided.

After the target warehouse slip is frozen, the frozen state of the target warehouse slip can be released under the condition that the block chain network receives a first checking result, namely a resource party checking result, and the resource party checking result representation is determined not to pass based on the intelligent contract. That is, in the case where the audit is not passed, it is determined that the current replacement audit process is ended, and therefore the frozen state of the target manifest can be released. If the audit is passed, the ownership of the target inventory is returned to the depositor, so that the target inventory can be directly placed in the failure state.

For the replacement manifest, after the block chain network receives the first audit result, whether the audit is passed or not, the frozen state of the replacement manifest can be released based on the intelligent contract, that is, the frozen state of the target manifest is released under the condition that the replacement is determined to be successful or failed. Since it will also exist for replacement orders whether audited or not, only the possessor may have changed.

In addition, the blockchain network can also record the appointed time length of the resource occupation of each storage party by an intelligent contract and record the occupied time length of the resource of the storage party, wherein, the two time lengths can be recorded when a target event is recorded, and the right of the resource party to the target warehouse bill is determined to be expired, the right of replacing the warehouse bill is refused to replace at least part of the right of the matched target warehouse bill. And refusing to replace at least part of the matched right of the target warehouse by using the right of the replacement warehouse when the right of the resource party to the target warehouse is determined to be expired. I.e., in the event that the inventory party needs to return the resource to the resource party, the storage party is no longer allowed to replace the target inventory with the replacement inventory. And, the processing result can be automatically generated so that the resource side client and the stocking side client provide the processing result to the resource side and the stocking side in a case where the resource side client and the stocking side client detect the processing result, so that the stocking side returns the corresponding resource to the resource side as soon as possible in exchange for the right of the objective manifest.

As can be seen from the above-mentioned scenario, in the case that the current value of the physical goods corresponding to the manifest is greatly different from the value of the physical goods in exchange for the resource, the inventory party usually has a need to obtain the physical goods corresponding to the manifest again.

For the depositor, it is not always concerned about the value change of the physical goods corresponding to the bills, and for a depositor, it is possible to simultaneously give ownership of a plurality of bills to the resource side in exchange for the resource, so it is not convenient for such depositor to be concerned about the value of the physical goods corresponding to each bill.

In order to solve the above problem, the present embodiment proposes the following:

in the warehouse receipt processing system, a freight rate monitoring client is added, and the freight rate monitoring client can be a certain node on the blockchain network or a user of the certain node on the blockchain network, namely the freight rate monitoring client can perform data interaction with the blockchain network.

The client of the freight rate monitoring party can submit the transaction for calling the freight rate replacement contract to the block chain network when the freight rate evidence storage condition of the entity freight corresponding to the target freight rate is met; the transaction initiated by the goods price deposit certificate transaction specifies the service input information required when the inventory replacement contract is called: the current unit price of the entity goods corresponding to the target manifest;

for example, when the stored entity goods are entity goods with value fluctuation attributes such as gold, silver and the like, the goods price monitoring party client may be a device corresponding to the trading exchange price equivalent monitoring mechanism. The method can monitor the value fluctuation condition of each entity goods, and the monitored value is the unit price of each type of entity goods in the general case, and the unit price can be the price of unit weight, the price of unit quantity and the like.

The aforementioned price deposit condition may be that a preset price deposit period is reached, for example, the price deposit period may be a period of one day, one week or one month, for example, the price monitoring side client may submit the current unit price of the entity goods corresponding to the target manifest to the block chain network at 9 am every day.

The goods price evidence condition can also be the sending change of the unit price of the physical goods, namely once the sending change of the unit price of the physical goods, the unit price of the physical goods is submitted to the block chain network;

the freight price evidence storing condition may be that the unit price of the entity goods corresponding to the target manifest is submitted to the blockchain network when the unit price change of the entity goods is detected to be large, for example, the unit price difference uploaded to the blockchain network last time is large.

The manner of obtaining the type of the entity goods corresponding to the target manifest by the freight monitoring party client may be by obtaining a manifest transfer transaction stored on the block chain network, that is, the identifier of each target manifest may be determined, and further, the type of the entity goods corresponding to each target manifest may be determined.

In addition, the client of the freight rate monitoring party does not need to know the type of the entity goods corresponding to the target warehouse slip, and only needs to submit the current unit prices of all the monitored entity goods to the block chain network.

After the goods price deposit evidence transaction is submitted to the block chain network by the goods price monitoring party client, the block chain network executes the warehouse receipt replacement contract, and compares the current unit price with the historical unit price to obtain a comparison result; the historical unit price is the unit price of the entity goods corresponding to the target bill when the bill transfer application event occurs; when the depositor transfers the right of the target warehouse slip to the resource depositor to exchange the right of the resource with the value matched, the unit price of the entity goods corresponding to the target warehouse slip;

and if the client of the stocking party monitors that the comparison result meets the preset condition from the block chain network, inquiring whether the stocking party triggers a warehouse receipt replacement application event or not.

The preset condition may be that the comparison result indicates that the current unit price of the entity goods is higher than the historical unit price, and the difference price is greater than a preset value; the comparison result may also indicate that the current unit price of the entity goods is lower than the historical unit price, and the difference price is greater than the preset value.

When inquiring, the client of the stock side can display the current unit price, the historical unit price, the difference between the two unit prices of the entity goods and the total quantity difference calculated based on the total quantity of the entity goods to the stock side, and the stock side can decide whether to trigger the stock replacement application event according to the information displayed by the client of the stock side.

For example, when it is determined that the value of the physical goods corresponding to the target manifest is increased more, the inventory side may trigger the manifest replacement application event, and may replace the target manifest with a replacement manifest of other physical goods with relatively stable value fluctuation, so as to obtain the physical goods corresponding to the target manifest, so as to obtain more resources by using the physical goods as soon as possible, for example, selling the physical goods or replacing the physical goods with a higher value manifest.

For example, when the value is low and the trend is continuously decreasing, the inventory side may trigger the inventory replacement application event in order to quickly replace the physical goods corresponding to the inventory for sale and stop the loss as soon as possible.

In the embodiment, the stocking party does not need to monitor the value fluctuation condition of the entity goods corresponding to each target warehouse receipt by himself, but the stocking party is based on the unit price data submitted to the block chain network by the stocking party client side and is checked based on the intelligent contract processing result in the block chain network, so that the overall intelligence is improved.

It is to be understood that the resources mentioned above may be resources such as funds, points, etc., and the description is not limited thereto.

When the resource is fund, the corresponding resource party can be each financial institution, such as a bank, a third-party payment institution and the like, the corresponding stocking party can be a party which has a fund borrowing demand for the financial institution, the corresponding stocking party can store the entity goods in the warehousing party and obtain the fund provided by the financial institution and matched with the value of the entity goods, and when the stocking party does not have sufficient fund to pay back to the financial institution but needs to obtain the entity goods stored in the warehousing party, the data generated by the auditing process of the warehouse slip and the warehouse slip replacement warehouse slip can be recorded on the block chain network in the above manner, so that the trust problem among the stocking party, the warehousing party and the financial institution is solved.
