Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of this invention belong. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Before further describing embodiments of the present invention in detail, the terms and terminology involved in the embodiments of the present invention will be described, and the terms and terminology involved in the embodiments of the present invention are suitable for the following explanation.

1) The sharing economy is a new economy mode based on strangers and with temporary transfer of the right to use the article, which aims to obtain a certain reward.

2) Transactions (transactions), which are equivalent to computer terms "transactions," include operations that need to be submitted to a blockchain network for execution, and do not refer solely to transactions in a business context, which embodiments of the present invention follow in view of the terminology "transactions" being colloquially used in blockchain technology.

For example, a deployment (Deploy) transaction is used to install a specified smart contract to a node in a blockchain network and is ready to be invoked; call (Invoke) transactions are used to append records of transactions in a blockchain by invoking smart contracts and to operate on a state database of the blockchain, including update operations (including adding, deleting, and modifying Key-Value pairs in the state database) and query operations (i.e., querying Key-Value pairs in the state database).

3) A blockchain (Block Chain) is a storage structure of encrypted, chained transactions formed by blocks (blocks).

For example, the header of each chunk may include both the hash values of all transactions in the chunk and the hash values of all transactions in the previous chunk, thereby enabling tamper-and anti-counterfeiting of transactions in the chunk based on the hash values; the newly generated transactions, after being filled into the block and passing through the consensus of the nodes in the blockchain network, are appended to the tail of the blockchain to form a chain growth.

4) A blockchain network (Block Chain Network) incorporates new blocks into a collection of nodes of a blockchain by way of consensus, with the ability to deploy intelligent contracts.

5) Ledger (Ledger), a generic term for blockchains (also known as Ledger data) and state databases that are synchronized with blockchains.

Wherein the blockchain records transactions in the form of files in a file system; the state database records transactions in the blockchain in the form of different types of Key (Key) Value pairs for supporting quick queries for transactions in the blockchain.

6) Smart contacts (Smart contacts), also known as Chain Code (Chain Code) or application Code, are deployed in a program in a node of a blockchain network, which program is triggered to execute according to conditions, the node executing a Smart contract invoked in a received transaction to update or query key values of a state database for data.

7) Consensus (Consensus), a process in a blockchain network for agreeing on transactions in blocks among the involved nodes, the agreed blocks will be appended to the tail of the blockchain, and mechanisms for implementing Consensus include Proof of Work (PoW), proof of equity (PoS), proof of equity (stare), proof of equity (DPoS), proof of-of-status, proof of elapsed time (PoET, proof of Elapsed Time), and the like.

8) A common blockchain refers to a blockchain that is readable by anyone worldwide, can send transactions and can be effectively validated, and can be engaged in a consensus verification process therein by anyone, which decides which blocks can be added to the blockchain and specifies the current state.

9) Private blockchains refer to blockchains whose write rights are in only one organization hand. The read right is either open to the outside or restricted to any extent.

10 A federated blockchain, refers to a blockchain whose consensus process is controlled by preselected nodes. A federated blockchain may be considered a blockchain that is common to many organizations or organizations, each of which manages one or more nodes in the federated chain.

11 In response to a condition or state that is indicative of a dependency of an operation performed, one or more operations performed may be in real-time or with a set delay when the dependency is satisfied; without being specifically described, there is no limitation in the execution sequence of the plurality of operations performed.

Referring to fig. 1, fig. 1 is a schematic diagram of an optional application architecture of a blockchain network-based article management system 100 according to an embodiment of the present invention, for implementing an exemplary application supported by the blockchain network-based article management system 100, the blockchain network-based article management system 100 includes a blockchain network 200 (in which a plurality of consensus nodes 210 are distributed in the blockchain network 200, the consensus node 210-1, the consensus node 210-2, and the consensus node 210-3 are illustrated, an article sharing service management platform 300, an authentication center 400, a service entity 500 (in which a terminal 500-1 and a graphical interface 510-1 thereof are illustrated and a service entity 600 (in which a terminal 600-2 and a graphical interface 610-2 thereof are illustrated and a terminal 600-2 thereof are illustrated and a service entity 500) are illustrated, and each part of the blockchain network-based article management system 100 is illustrated.

The type of blockchain network 200 is flexible and diverse, and may be any of public blockchains (abbreviated as public chains), private blockchains (abbreviated as private chains), or federated blockchains (abbreviated as federated chains), for example. Taking public chains as an example, any electronic device of a business entity, such as a user terminal and a server, can access the blockchain network 200 without authorization; taking the alliance chain as an example, after the service body obtains the authorization, the electronic devices (such as a user terminal and a server) under the jurisdiction of the service body can access the blockchain network 200, and at this time, the service body can become a client node in the blockchain network 200.

In some embodiments, the client node may be implemented as a mere observer of the blockchain network 200, i.e., providing functionality to support a business entity to initiate transactions (e.g., for storing data in the uplink or querying data on the chain), for functions of the consensus node 210 in the blockchain network 200, such as ordering functions, consensus functions, and ledger functions (e.g., functions of a query status database), etc., by default or selectively (e.g., depending on the specific business needs of the business entity), so that the business entity's data and business processing logic may be migrated to the blockchain network 200 to the maximum extent, with the reliability and traceability of the data and business processing processes being achieved by the blockchain network 200.

The consensus node 210 in the blockchain network 200 receives transactions submitted from terminals (e.g., terminal 500-1 belonging to the business entity 500 and terminal 600-2 belonging to the business entity 600 shown in fig. 1) of different business entities (e.g., business entity 500 and business entity 600 in fig. 1), performs the transactions to update or query the ledger, and various intermediate or final results of the performed transactions may be returned to the user interface of the terminal of the business entity (e.g., graphical interface 510-1 of terminal 500-1 and graphical interface 610-2 of terminal 600-2) for display.

An exemplary application of a blockchain network is described below taking as an example a plurality of business agents accessing the blockchain network to effect business management of shared items.

Referring to fig. 1, in the present embodiment, a plurality of service principals involved in a service management process for sharing an article, for example, a service principal 500 may be an article sharing party, a service principal 600 may be an article using party, and different service principals (for example, the service principal 500 and the service principal 600) register with an authentication center (CA, certificate Authority) 400 respectively to obtain respective digital certificates (including a public key of the service principal, and a digital signature signed by the CA for the public key and identity information of the service principal), and are used to be attached to a transaction together with a digital signature of the service principal for the transaction, and sent to a blockchain network 200. Wherein, after obtaining authorization of the article sharing service management platform 300, clients running by devices (such as user terminals or servers) of different service entities can request access to the blockchain network 200 to become client nodes.

The service person of the service entity 500 logs in the client of the terminal 500-1, inputs user identity information, item information of an item to be shared or a benefit inquiry request, the user identity information, the item information of the item to be shared or the benefit inquiry request is sent to the item sharing service management platform 300, the user identity information is authenticated by the item sharing service management platform 300, when the user identity information is authenticated, a transaction corresponding to the update operation or the inquiry operation is generated by the item sharing service management platform 300 according to the item information or the benefit inquiry request, an intelligent contract required to be invoked for implementing the update operation or the inquiry operation and parameters (for example, the identity information of the service entity 500) transferred to the intelligent contract are specified in the transaction, a digital certificate of the service entity 500, a signed digital signature (for example, a private key of the digital certificate of the client of the terminal 500-1 is used), the digest of the transaction is encrypted, the service entity 500 can be registered and registered to the authentication center 400 to obtain the digital certificate, and the transaction is broadcasted to the consensus node 210 in the blockchain network 200.

When the consensus node 210 in the blockchain network 200 receives a transaction, it verifies the digital certificate and the digital signature carried by the transaction respectively, and after the digital certificate and the digital signature are verified successfully, it confirms whether the service body 500 has transaction authority according to the identity information of the service body 500 carried in the transaction, and any one verification result of the digital signature and the authority verification will cause the transaction to fail. After the rights verification is successful, the consensus node 210 signs its own digital signature (e.g., encrypts the digest of the transaction using the private key of the consensus node 210-1) and continues to broadcast in the blockchain network 200.

After receiving a transaction that is successfully validated, the consensus node 210 in the blockchain network 200 populates the new block with the transaction and broadcasts the transaction. When the consensus node 210 in the blockchain network 200 broadcasts a new block, a consensus process is performed on the new block, if the consensus is successful, the new block is added to the tail of the blockchain stored in the new block, and the state database is updated according to the result of the transaction, so as to execute the transaction in the new block: for the transaction of submitting updated article information, updating the key value pair corresponding to the article information in the state database; for the trade of the obtained benefits, the key value pair corresponding to the obtained benefits is inquired from the state database, and the trade result is returned.

Similarly, the business person of the business entity 600 logs in the client of the terminal 600-2, inputs an item inquiry request, the item inquiry request is sent to the item sharing business management platform 300, the item sharing business management platform 300 generates a transaction corresponding to the inquiry operation according to the item inquiry request, an intelligent contract required to be invoked for realizing the inquiry operation and parameters transferred to the intelligent contract are specified in the transaction, a digital certificate of the client of the terminal 600-2 and a signed digital signature are carried in the transaction (for example, a private key of the digital certificate of the client of the terminal 600-2 is used, and a digest of the transaction is encrypted) and broadcast to the consensus node 210 in the blockchain network 200.

When the consensus node 210 in the blockchain network 200 receives a transaction, it verifies the digital certificate and the digital signature carried by the transaction respectively, and after both the digital certificate and the digital signature are verified successfully, it confirms whether the service body 600 has transaction authority according to the identity information of the service body 600 carried in the transaction, and any one verification result of the digital signature and the authority verification will cause the transaction failure. After the rights verification is successful, the consensus node 210 signs its own digital signature (e.g., encrypts the digest of the transaction using the private key of the consensus node 210-1) and continues to broadcast in the blockchain network 200.

After receiving a transaction that is successfully validated, the consensus node 210 in the blockchain network 200 populates the new block with the transaction and broadcasts the transaction. When the consensus node 210 in the blockchain network 200 broadcasts a new block, a consensus process is performed on the new block, if the consensus is successful, the new block is added to the tail of the blockchain stored in the new block, and the state database is updated according to the result of the transaction, so as to execute the transaction in the new block: for the transaction of inquiring the articles meeting the screening conditions, inquiring the key value pairs corresponding to the articles meeting the screening conditions from the state database, and returning a transaction result.

As can be appreciated, the type of data that a business entity can query/update in the blockchain network 200 can be achieved by restricting the rights of transactions that the business entity can initiate, for example, when the business entity 500 has the rights to initiate transactions for the benefits obtained by the query, the business personnel of the business entity 500 can input a benefit query request in the graphical interface 510-1 of the terminal 500-1 and generate a transaction for querying the benefits obtained by the item sharing business management platform 300 and broadcast the transaction into the blockchain network 200 to obtain the corresponding benefits from the blockchain network 200;

when the service entity 600 has authority to initiate a transaction for querying the item meeting the screening condition, the service personnel of the service entity 600 may input an item query request in the graphic interface 610-2 of the terminal 600-2, generate a transaction for querying the item meeting the screening condition by the item sharing service management platform 300, and broadcast the transaction to the blockchain network 200 to obtain the corresponding item meeting the screening condition from the blockchain network 200.

As an example of a blockchain, referring to fig. 2, fig. 2 is a schematic diagram of an alternative structure of a blockchain in a blockchain network 200 according to an embodiment of the present invention, where a header of each block may include hash values of all transactions in the block, and also include hash values of all transactions in a previous block, and a record of a newly generated transaction is filled into the block and appended to a tail of the blockchain after being identified by an identified node in the blockchain network, so as to form a chain type growth, and a chain structure based on the hash values between the blocks ensures tamper resistance and forgery resistance of the transactions in the block.

For example, as an example of software modules, the memory 302 may include the blockchain network-based article management device 40 provided in the embodiment of the present invention, which may be software in the form of a program, a plug-in, or the like, including a series of software modules, and fig. 5 is a schematic diagram of an optional component structure of the blockchain network-based article management device 40 provided in the embodiment of the present invention, where, for example, the blockchain network-based article management device 40 includes a first receiving unit 41, an authentication unit 42, a storage unit 43, a second receiving unit 44, a querying unit 45, and a rights transferring unit 46, and the functions of these units are logically combined, so that any combination or further splitting may be performed according to the functions implemented by the respective software modules. It should be noted that, for the specific functions of each unit in the blockchain network-based item management device 40 provided in the embodiment of the present invention shown in fig. 5, the following description will be given.

The implementation of the blockchain network-based item management method provided by the embodiment of the invention will be described below in connection with exemplary applications and implementations of the blockchain network provided by the embodiment of the invention.

Referring to fig. 6, fig. 6 is a schematic flowchart of an alternative method for managing articles based on a blockchain network according to an embodiment of the present invention, it may be understood from the foregoing that an article sharing service management platform implementing the blockchain network based article management method according to an embodiment of the present invention may be deployed in an electronic device (for example, a user terminal or a server), and the deployment of the article sharing service management platform in the server is taken as an example, and the following description will be given with reference to the steps shown in fig. 6.

In step 601, the item sharing party logs in to the item sharing business management platform for registration service.

In some embodiments, the article sharing party logging in the article sharing service management platform to perform registration service can be implemented by the following ways: business personnel of the article sharing party inputs a request of registration service through a graphical interface of a first terminal belonging to the article sharing party so as to send the request of registration service to the article sharing business management platform, the article sharing business management platform performs authorization verification on the article sharing party according to the request of registration service, and after the article sharing party obtains authorization of the article sharing business management platform, the business personnel can log in the article sharing business management platform and perform corresponding registration service on the article sharing business management platform.

Here, the business person of the article sharing party is used to represent the user who shares the article that is idle, and the shared article can be leased by others. Registering the service includes registering at least one of the following information: personal information of users sharing the items; item information for the item to be shared.

Wherein the personal information of the user sharing the item includes at least one of the following information: the user identity information such as the name, the identification card number, the mobile phone number, the face image and the like of the user sharing the article can also comprise a user account number (such as a bank card number) for the user to settle the cost. The article information of the article to be shared comprises basic information of the article to be shared, such as color, material, model, used fuel and the like of the article to be shared, and can also comprise position information of the article to be shared, an image of the article to be shared and payment transaction rules of the article to be shared.

In step 602, the item sharing service management platform receives user identity information uploaded by a first terminal corresponding to an item sharing party and item information of an item to be shared, in response to a registration service of the item sharing party.

In step 603, the item sharing service management platform authenticates the user identity information.

In some embodiments, referring to fig. 7, fig. 7 is a schematic flow chart of another alternative method for managing articles based on a blockchain network according to an embodiment of the present invention, based on fig. 6, the authentication of the user identity information in the step 603 may be further implemented by the following steps 6031 to 6033, which will be described below in connection with the steps.

In step 6031, the item sharing service management platform invokes an interface of the authentication center to acquire a digital certificate of the item sharing party.

In step 6032, the digital certificate of the item sharing party is verified, and when the digital certificate of the item sharing party passes the verification, the public key corresponding to the item sharing party in the digital certificate is extracted.

In step 6033, the user identity information is authenticated based on the public key corresponding to the item sharing party.

In the embodiment of the invention, the user identity information uploaded by the first terminal corresponding to the article sharing party can comprise signature information corresponding to the user identity information obtained by the article sharing party performing digital signature on the user identity information. The implementation process of digital signature on the user identity information by the article sharing party is described below, specifically, firstly, the article sharing party extracts the abstract of the user identity information based on the abstract algorithm to obtain the abstract value of the user identity information; then, the article sharing party encrypts the abstract value of the user identity information by utilizing the private key of the article sharing party so as to form corresponding signature information.

Here, before the article sharing party digitally signs the user identity information, the article sharing party may first register with the authentication center to obtain the digital certificate of the article sharing party, and the authentication center may generate the public-private key pair in the digital certificate of the article sharing party based on the key generation algorithm. The public-private key pair comprises a public key and a private key corresponding to the public key. The key generation algorithm includes a symmetric key generation algorithm and an asymmetric key generation algorithm. In order to increase the security of the key and to ensure the non-tamperability of the signature result, the key generation algorithm may preferably be an asymmetric key generation algorithm. The public key can pass verification in the blockchain network and corresponds to the private key; the private key is used for the item sharing party to digitally sign the digest value of the user identity information. It should be noted that only the public key of the digital certificate can be verified and displayed in the blockchain network, but the private key is not generally existed in the blockchain network, so as to ensure the security of the private key.

In some examples, the public key of the authentication center is held by the article sharing service management platform to verify the digital certificate sent by the article sharing party, when the verification passes, the article sharing service management platform can extract the public key in the digital certificate of the article sharing party, and the public key is used for authenticating the signature information of the user identity information uploaded by the first terminal corresponding to the article sharing party, and when the authentication passes, the authenticity and the reliability of the signature information of the uploaded user identity information are proved to be higher.

In some embodiments, prior to performing step 603, the blockchain network-based item management method may further include: requesting access rights for the article sharing direction blockchain network; and receiving a digital certificate distributed by the blockchain network for the article sharing party, wherein the digital certificate is used for signing a corresponding digital signature with the article information aiming at the article to be shared so as to declare the identity information of the article sharing party to the blockchain network.

In embodiments of the present invention, the item sharing service management platform is deployed independent of the blockchain network, that is, the item sharing service management platform is an entity that exists independent of the blockchain network. Therefore, in order to realize the solution of sharing the goods by using the blockchain technology, the participants in the process of managing the goods sharing service, such as the party sharing the goods, the party using the goods, and the like, need to access to the blockchain network after obtaining the authorization of the platform for managing the goods sharing service, otherwise, the participants in the process of managing the goods sharing service cannot access to the blockchain network without obtaining the authorization of the platform for managing the goods sharing service.

In step 604, the item sharing business management platform stores item information for the item to be shared into the blockchain network when the user identity information authentication passes.

In the embodiment of the invention, the article information of the article to be shared is stored in the form of key value pairs, specifically, when the user identity information passes the authentication, the article sharing service management platform takes the identification information of the article to be shared as a key and takes the encrypted article information as a value, the key value pairs corresponding to the article information of the article to be shared are formed by combining, and the transaction carrying the key value pairs is sent to the consensus node in the blockchain network so as to store the key value pairs to the consensus node.

In some embodiments, referring to fig. 8, fig. 8 is a schematic flow chart of another alternative method for managing articles based on a blockchain network according to an embodiment of the present invention, based on fig. 6, the storing of the article information of the article to be shared in the blockchain network in step 604 may also be implemented by the following step 6041 and step 6042, which will be described below in connection with the steps.

In step 6041, the item sharing business management platform sends item information for the item to be shared into the blockchain network to cause nodes of the blockchain network to generate new blocks of item information corresponding to the item to be shared.

In step 6042, when the node providing the consensus service among the nodes of the blockchain network agrees with the consensus for the new block, the new block which has taken the consensus is added to the tail of the blockchain for storing the item information of the item to be shared by the blockchain network.

Specifically, the article sharing service management platform initiates a data transaction request to the blockchain network, wherein the data transaction request carries article information of articles to be shared and versions of intelligent contracts to be called; after receiving the data transaction request, the blockchain network generates a new block of article information corresponding to the article to be shared, signature information corresponding to the article information of the article to be shared is stored in the new block, and when a plurality of nodes providing consensus service in the blockchain network agree on the article information of the article to be shared and the corresponding signature information, the article sharing service management platform invokes the corresponding intelligent contract according to the version of the intelligent contract to be invoked, and writes the article information of the article to be shared and the corresponding signature information into the blockchain network by executing the intelligent contract.

In the embodiment of the invention, after the object sharing service management platform initiates a data transaction request to the blockchain network, each node in the blockchain network broadcasts the data transaction request sent by the object sharing service management platform to the whole network, wherein the data transaction request can be broadcast to the whole network in a P2P mode, at this time, a plurality of nodes providing consensus services in the blockchain network vote the object information of the object to be shared and the corresponding signature information, and based on a consensus mechanism adopted by the blockchain network, when the agreement of the transaction among the plurality of nodes providing the consensus services, such as voting, reaches a set condition, the object sharing service management platform can call the corresponding intelligent contract according to the version of the intelligent contract to be called, and write the object information of the object to be shared and the corresponding signature information into the blockchain network through executing the called intelligent contract. Because the blockchain network has the characteristics of non-tampering and non-revocable, the article information of the article to be shared and the corresponding signature information are stored in the blockchain network, so that the safety and the reliability of the data stored in the blockchain network can be ensured.

In other embodiments, the item sharing business management platform may further store item information for the item to be shared into the blockchain network in the following manner: and carrying out hash processing on the original data representing the article information to obtain a hash value of the corresponding article information, and storing the hash value of the article information into the blockchain network.

For example, the item information of the item to be shared may include only a small amount of text information, for example, text information including color, material, model, etc. of the item to be shared, and then the item sharing service management platform may directly store the text information including color, material, model, etc. of the item to be shared into the blockchain network. Of course, when the text information included in the item information of the item to be shared is large, for example, detailed description information of the item to be shared is included, the obtained hash value can be stored into the blockchain network by determining the hash value of the text information included in the item information of the item to be shared, so as to reduce the volume of the blockchain.

In other embodiments, the item sharing business management platform may further store item information for the item to be shared into the blockchain network in the following manner: determining text information included in original data representing the item information, and storing the text information into a blockchain network; and determining multimedia information included in the original data representing the article information, carrying out hash processing on the multimedia information to obtain a hash value corresponding to the multimedia information, and storing the hash value of the multimedia information into the blockchain network.

For example, the article information of the article to be shared may also include multimedia information, for example, an image of the article to be shared, the hash value corresponding to the image of the article to be shared may be determined first, the obtained hash value of the image of the article to be shared is stored in the blockchain network, and the text information and the multimedia information included in the article information of the article to be shared are stored separately in the blockchain network, so as to reduce the volume of the blockchain.

In step 605, a second terminal corresponding to the article user sends an article inquiry request to the article sharing service management platform.

In the embodiment of the invention, the item inquiry request carries the screening condition corresponding to the second terminal. For example, the client in the second terminal receives the screening condition of the shared object to be used, which is set in the graphical interface by the object user, and includes one or more of the following: color, material, model, and (type of) fuel used, etc.; but also the location of the shared object to be used.

In step 606, the item sharing business management platform queries the blockchain network for items that meet the screening criteria among the items to be shared in response to the item query request.

In some embodiments, referring to fig. 9, fig. 9 is a schematic flow chart of another alternative method for managing articles based on a blockchain network according to the embodiment of the present invention, based on fig. 6, in step 606, in response to an article query request, the querying of articles to be shared from the blockchain network for articles meeting the screening condition may also be implemented by the following steps 6061 and 6062, which will be described below in connection with the steps.

In step 6061, the item query request is parsed to obtain the identification and screening conditions of the query smart contract to be invoked.

In step 6062, the identification of the query intelligent contract to be invoked and the screening condition are sent to the blockchain network, so that the consensus node in the blockchain network executes the corresponding query intelligent contract based on the identification of the query intelligent contract to be invoked, and queries the article which meets the screening condition and is in the unused state from the stored article information.

As an example of the item inquiry request, the item inquiry request carries the identification and the screening condition of the inquiry intelligent contract to be invoked, the corresponding inquiry intelligent contract is executed by the consensus node in the blockchain network, so as to inquire the item which accords with the screening condition and is in an unused state (for example, the second terminal corresponding to the item user can periodically locate the position information of the shared item to determine whether the shared item is used or not) in the account state, and the position of the inquired item is displayed in the graphical interface of the client of the second terminal. Here, the account state may be queried with the identification of the article (the article information in the account state is stored in the form of key value pairs, so that the query efficiency may be improved, and of course, the account data may also be queried directly), so as to query the article which meets the screening condition and is in the unused state.

In step 607, the item sharing service management platform transfers the usage rights of the items meeting the screening conditions from the first terminal to the second terminal, so that the second terminal executes the usage rights of the items meeting the screening conditions.

In the embodiment of the invention, the article shared by the article sharing party can refer to a device which has a locking function and can release the locking state according to the unlocking password and has a walking and/or transportation function, such as a sharing bicycle. When the user of the second terminal arrives at the position of the displayed inquired article, in order to ensure that the article with the use authority possessed by the user of the second terminal is the article which is shared in the blockchain network, before the use authority of the article which accords with the screening condition is executed, the article information of the article to be used can be inquired to the blockchain network, when the identification information of the corresponding article is extracted from the article information and is consistent with the identification information obtained by scanning the article, the user of the second terminal can be determined to be the correct position of the article to be used, the subsequent second terminal can request consensus to obtain the unlocking password by sending the article information corresponding to the inquired article to the blockchain network, so that the locking state of the article is released based on the unlocking password, the condition that the unlocking password is requested to fail because the wrong position is reached is avoided, and the efficiency of the article sharing is ensured.

In the embodiment of the present invention, when an item is unlocked and used by an item user, for example, the item user using a shared item is triggered to end use in a client, or no position movement occurs during an item exceeding waiting time, a process of charging a lease fee from the item user using the shared item with reference to the accompanying drawings and transferring the lease fee to a user account of the item sharing party is described below.

In some embodiments, referring to fig. 10, fig. 10 is another optional flowchart of a method for managing articles based on a blockchain network according to an embodiment of the present invention, and based on fig. 6, after step 607, the article sharing service management platform may further perform steps 608 to 610. The following will explain the steps.

In step 608, when it is detected that the article meeting the screening condition is started to be used, a payment interface is invoked to pre-deduct the fee from the user account of the second terminal.

In step 609, when it is detected that the use of the item conforming to the screening condition is completed, the pre-deduction fee is verified based on the payment transaction rule of the item and the charging data of the item conforming to the screening condition, so as to determine the lease fee for using the item conforming to the screening condition.

In step 610, the lease fee is transferred to the user account of the first terminal, and the usage rights of the articles meeting the screening conditions are transferred from the second terminal to the first terminal.

In some examples, for transferring lease fees to a user account of a first terminal, this may be accomplished in the following manner: firstly, transferring lease fees into an intermediate account, wherein the intermediate account is a third party account independent of a user account of a first terminal and a user account of a second terminal, and generating payment transactions using articles meeting screening conditions; secondly, sending the payment transaction to a consensus node in the blockchain network for the consensus node to consensus the payment transaction; finally, when the consensus for the payment transaction passes, a collection intelligence contract in the consensus node is invoked to transfer the lease fees from the intermediate account to the user account of the first terminal.

Here, the payment interface of the financial institution (e.g., bank) corresponding to the second terminal is called by the article sharing service management platform, the user account of the second terminal corresponding to the article user who uses the shared article is deducted in advance, and the fee is transferred to the intermediate account of the third party financial institution, where the intermediate account is a third party account independent of the user account of the first terminal and the user account of the second terminal. Before the fee is deducted from the user account of the second terminal, the article sharing service management platform may also send the identification information of the user of the article sharing party to the consensus node in the blockchain network to perform identity verification, and when the verification passes, the fee is deducted from the user account of the second terminal corresponding to the article using party, so as to ensure the safety of funds.

Here, the deduction fee is paid in a refund and repayment manner to transfer the lease fee to the intermediate account. As an example of a payment transaction, a consensus node in the blockchain network can agree on whether the lease fees are accurate or not based on the identity of the user sharing the item, the identity of the item, and billing data carried in the payment transaction. For example, the lease fee of the used article can be calculated according to the payment transaction rule of the article by combining the charging data (taking the shared article as the shared bicycle as an example, the charging data such as the driving distance and the driving duration) of the article meeting the screening condition, and the charging mode of the payment transaction rule of the article can be set by the article sharing party or can be a uniform charging mode.

It should be noted that, the consensus node in the blockchain network obtains the identification of the article meeting the screening condition from the payment transaction, inquires the payment transaction rule stored in the uplink, determines the lease fee according to the charging data carried in the payment transaction, and if the lease fee is consistent with the lease fee carried in the payment transaction, signs the payment transaction. When a sufficient number of consensus nodes sign a payment transaction, then the consensus of the payment transaction passes, and when the use of the item is over, the consensus nodes in the blockchain network run a collection intelligent contract to invoke a payment interface to transfer the lease fee from the intermediate account to the user account of the first terminal, thereby completing the fee collection for using the shared item. Of course, the fee transferred to the intermediate account requires a refund operation according to the fee actually used.

In some embodiments, referring to fig. 11, fig. 11 is another optional flowchart of a method for managing articles based on a blockchain network according to an embodiment of the present invention, and based on fig. 10, after step 610, the article sharing service management platform may further perform steps 611 to 613. The following will explain the steps.

In step 611, an article maintenance request sent by a third terminal corresponding to the article maintenance party is received, where the article maintenance request carries identification information of an article to be maintained.

In step 612, in response to the item maintenance request, the identification information is sent to a consensus node in the blockchain network, so that the consensus node performs consensus on the item to be maintained corresponding to the identification information, and when the consensus passes, a notification message indicating that maintenance is permitted is generated.

In step 613, a notification message returned by the blockchain network is received and sent to the third terminal, so that the third terminal can maintain the article to be maintained.

In the embodiment of the invention, an article sharing service management platform sends a consensus request to a consensus node in a blockchain network, wherein the consensus request carries the identification of a consensus intelligent contract and the identification of an article to be maintained, the consensus node in the blockchain network executes the consensus intelligent contract to inquire the state of an account book according to the identification of the article to be maintained so as to verify whether the article to be maintained submitted by a third terminal corresponding to an article maintainer is consistent with the information corresponding to the inquired article, and if a sufficient number of consensus nodes (for example, more than half of the consensus nodes) are confirmed to be consistent, the consensus passes, so that a notification message indicating that maintenance is permitted is generated.

In some embodiments, the blockchain network-based item management method further includes: when the maintenance of the article to be maintained is detected to be completed, determining maintenance cost corresponding to the article to be maintained based on the maintenance transaction rule of the article, and transferring the maintenance cost to a user account of the third terminal.

In some examples, when the maintenance of the article to be maintained by the article maintainer is completed, the maintenance fee can be deducted from the user account of the first terminal having ownership of the shared article and the last terminal having use right of the shared article, such as the user account of the second terminal, and the maintenance fee is transferred to the user account of the third terminal, so that the article maintainer maintains the shared article which is damaged arbitrarily and charges a certain maintenance fee, the cost of the operator is greatly reduced, and the operation efficiency of the article sharing is improved.

Compared with the scheme of realizing the article sharing by an article management system inside a service provider in the related art, by adopting the technical scheme provided by the embodiment of the invention, through introducing the blockchain technology and based on the decentralization characteristic of the blockchain network, a user (comprising an article sharing party and an article using party) participates in the whole construction process of the shared article network, namely, the user (the article sharing party) submits the idle article to the blockchain network for lease by other people (the article using party) without completely relying on the restriction of a third party platform, and the operation efficiency of the article sharing is improved; storing the article information of the article sharing party into a blockchain network, and tracing the whole process of article sharing according to the article information by utilizing the characteristics of non-tampering and non-revocable of the blockchain network, so as to ensure the safety and traceability of the article information; meanwhile, the articles meeting the screening conditions are inquired from the blockchain network for the article users to rent, and the credibility of the article sharing process can be improved.

In the following, an exemplary application of the embodiment of the present invention in a practical application scenario will be described.

Before an application scenario of the embodiment of the present invention is illustrated, a sharing scheme of related art items is illustrated. Referring to fig. 12, fig. 12 is a flow chart of a method for sharing items provided by the related art, in which a service provider (i.e. an operator providing an item sharing service) throws a large number of shared items, such as internet products such as a sharing bicycle, a sharing car, etc., in different areas, and the large number of shared items form a shared item pool, and when a user needs to use the shared items provided by the service provider, the shared items can be preferentially selected from the shared item pool so as to directly use the selected shared items.

It can be seen that the related art sharing economic products, such as sharing bicycles, etc., are short-term rental services provided to users by service providers, and short-term usage rights of items are purchased by users to realize a sharing mode of the items. However, the above-described service provider operation has several problems: firstly, a service provider needs to invest huge funds to construct a relatively perfect shared network, so that the operation cost is high, a server for storing article information is easy to be an object of network attack, the article sharing participants are not trusted, and the credibility of the article sharing process is reduced; secondly, the leasing scale and the coverage scale of the shared articles are completely dependent on the release strength of the service provider, so that the user has low participation, namely, the user can only lease the articles provided by the service provider and can not lease the idle articles; third, for damaged shared items, the service provider is required to perform maintenance in person, and often the damaged shared items may be distributed in different geographical locations, resulting in high operation cost and reduced operation efficiency.

In order to solve at least the technical problems of the related art, the article management method, the device, the electronic equipment and the storage medium based on the blockchain network provided by the embodiment of the invention can enable a user to participate in the construction process of the whole shared article network through the decentralization characteristic of the blockchain network, namely, the user can store the idle articles into the blockchain network for leasing by other people without completely relying on the shared service of a service provider, thereby not only ensuring the safety and traceability of article information, but also improving the operation efficiency of article sharing; meanwhile, a user can maintain any damaged article and charge a certain fee, so that the operation cost is greatly reduced, and the operation efficiency is improved.

Referring to fig. 13, fig. 13 is a schematic diagram of an alternative principle structure of a blockchain network-based item management method provided by an embodiment of the present invention, where participants involved in an item management process in the embodiment of the present invention include a user a (a sharing party of an item, i.e., a user sharing an item), a user B (a user of an item, i.e., a user renting an item to be shared), and a user C (a maintenance party of an item, i.e., a user maintaining a damaged item to be shared), and a process for implementing the blockchain network-based item management scheme provided by the embodiment of the present invention is described below.

Firstly, a user A submits article information of an idle article (article to be shared) and user identity information to an article sharing service management platform, the article sharing service management platform authenticates the user identity information of the user A, when the authentication passes, the article information of the idle article submitted by the user A is stored in a chain, namely, the article information of the idle article submitted by the user A is stored in a blockchain network, and when the article information is successfully linked, the blockchain network distributes ownership and use right of the idle article submitted by the user A. Therefore, the user A submits the idle articles to the blockchain network for the other to rent and charges corresponding renting fees, so that the information safety of the shared articles is protected, meanwhile, the automation of the sharing and renting processes is realized, and no manual intervention is needed. The user a can upload the idle articles through the interface for submitting the shared articles shown in fig. 14, and also need to submit the photos and ownership documents of the shared articles at the same time. Here, when submitting the idle articles, the user a must pay a certain maintenance fund for the maintenance of the subsequent shared articles.

And then, when the user B needs to use the articles shared by other users, the terminal corresponding to the user B sends an article inquiry request to an article sharing service management platform, wherein the article inquiry request is used for requesting to use the shared articles stored on the chain, and meanwhile, a certain deposit is required to be paid. After the end of the use of the shared object, the user B needs to return the right to use the shared object to the user a.

In the process of article management, when a user C finds that a certain shared article is damaged, the user C can send an article maintenance request to an article sharing service management platform to request maintenance of the damaged shared article, the article maintenance request carries an identification of the article to be maintained, the article sharing service management platform responds to the article maintenance request and sends identification information to a blockchain network, so that a consensus node in the blockchain network carries out consensus on the article to be maintained corresponding to the identification information, when the consensus is passed, a notification message permitting maintenance is generated, and after the article sharing service management platform receives the notification message returned by the blockchain network, the notification message can be sent to the user C, so that the user C can execute maintenance of the article to be maintained, and when the maintenance of the user C is completed, corresponding maintenance cost is deducted from an account with ownership of the article, namely a user account number of the user A, and a last account with use right of the article, namely a user account number of the user B, and the maintenance cost is classified into the user account number of the user C.

It should be noted that, the user a may query all the lending items and the corresponding benefits through the query interface shown in fig. 15, and achieve the purpose of getting the benefits of renting the shared items by one key through the benefit getting interface shown in fig. 15. When no user uses the shared item of the user a or the user a wants to use the shared item, the purpose of retrieving the shared item can be achieved through the interface for retrieving the shared item shown in fig. 14. The user C may submit a maintenance request for maintaining the damaged shared object to the object sharing service management platform through an operation of a maintenance application button shown in fig. 16, and maintain the damaged shared object after the user C receives a notification message for permitting maintenance, when the maintenance is completed, the photos of the shared object before and after the maintenance need to be uploaded to the blockchain network at the same time, and a consensus node in the blockchain network may determine that the user C has indeed maintained the damaged shared object by comparing the photos of the shared object before and after the maintenance, and at this time, by providing an interface for retrieving maintenance charges, the user C may retrieve corresponding maintenance charges after the maintenance of the shared object is completed.

In addition, it should be noted that the user a may sell ownership of the belonging item through the entire sharing network, or may purchase ownership of the shared item by other people.

According to the article management method based on the blockchain network, provided by the embodiment of the invention, based on the decentralization characteristic of the blockchain network, a user participates in the construction process of the whole shared article network, and can submit the idle articles to the blockchain network for leasing by others, so that the operation efficiency of article sharing is improved; storing the article information of the article sharing party into a blockchain network, and tracing the whole process of article sharing according to the article information by utilizing the characteristics of non-tampering and non-revocable of the blockchain network, so as to ensure the safety and traceability of the article information; meanwhile, the article maintainer maintains any damaged shared articles and charges certain maintenance cost, so that the cost of operators is greatly reduced, the operation efficiency of article sharing is improved, and the problem that a large number of shared articles are changed into social garbage due to unmanned maintenance at present is solved.

A software implementation of the blockchain network-based item management device 40 provided by an embodiment of the present invention is described next. The software modules included in the memory 302 of the electronic device 30 are described by way of example, and reference may be made to the above for inexhaustible details regarding the functional description of the modules.
