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 the present invention belong. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Before further detailed description of the embodiments of the present invention, terms and expressions mentioned in the embodiments of the present invention are explained, and the terms and expressions mentioned in the embodiments of the present invention are applied to the following explanations.

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

2) Transactions (transactions), equivalent to the computer term "Transaction," include operations that need to be committed to a blockchain network for execution and do not refer solely to transactions in the context of commerce, which embodiments of the present invention follow in view of the convention colloquially used in blockchain technology.

For example, a deployment (deployment) transaction is used to install a specified smart contract to a node in a blockchain network and is ready to be invoked; the call (Invoke) transaction is used for adding a record of the transaction in the blockchain by calling an intelligent contract, and performing operations on a state database of the blockchain, including updating 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) Block Chain (Block Chain) is a storage structure for encrypted, chained transactions formed by blocks (blocks).

For example, the header of each block may include hash values of all transactions in the block, and also include hash values of all transactions in the previous block, so as to achieve tamper resistance and forgery resistance of the transactions in the block based on the hash values; newly generated transactions, after being filled into the tiles and passing through the consensus of nodes in the blockchain network, are appended to the end of the blockchain to form a chain growth.

4) A Block Chain Network (Block Chain Network) incorporates a new Block into a set of a series of nodes of a Block Chain in a consensus mode, and has the capacity of deploying intelligent contracts.

5) Ledger (legger) is a general term for blockchains (also called Ledger data) and state databases synchronized with blockchains.

Wherein, the blockchain records the transaction in the form of a file in a file system; the state database records the transactions in the blockchain in the form of different types of Key (Key) Value pairs for supporting fast query of the transactions in the blockchain.

6) Intelligent Contracts (Smart Contracts), also called Chain codes (Chain codes) or application codes, are programs deployed in nodes of a blockchain network, the programs are triggered to be executed according to conditions, and the nodes execute the intelligent Contracts called in received transactions to update or inquire key value pair data of a state database.

7) Consensus (Consensus), a process in a blockchain network, is used to agree on transactions in a block among a plurality of nodes involved, the agreed block is to be appended to the end of the blockchain, and the mechanisms for achieving Consensus include Proof of workload (PoW, Proof of Work), Proof of rights and interests (PoS, Proof of equity (DPoS), Proof of granted of shares (DPoS), Proof of Elapsed Time (PoET, Proof of Elapsed Time), and so on.

8) The public blockchain is a blockchain which can be read by anyone all over the world, can send a transaction, can effectively confirm the transaction, and can participate in a consensus verification process, wherein the consensus process determines which block can be added into the blockchain and defines the current state.

9) Private blockchain, refers to a blockchain whose write rights are in only one organization's hand. The read right is either open to the outside or is limited to any extent.

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

11) In response to the condition or state on which the performed operation depends, one or more of the performed operations may be in real-time or may have a set delay when the dependent condition or state is satisfied; there is no restriction on the order of execution of the operations performed unless otherwise specified.

Referring to fig. 1, fig. 1 is a schematic diagram of an optional application architecture of an article management system 100 based on a blockchain network according to an embodiment of the present invention, in order to implement an exemplary supported application, the article management system 100 based on a blockchain network includes a blockchain network 200 (where a plurality of consensus nodes 210, illustratively showing a consensus node 210-1, a consensus node 210-2, and a consensus node 210-3, are deployed in the blockchain network 200), an article-sharing service management platform 300, an authentication center 400, a service agent 500 (illustratively showing a terminal 500-1 belonging to the service agent 500 and a graphical interface 510-1 thereof) and a service agent 600 (illustratively showing a terminal 600-2 belonging to the service agent 600 and a graphical interface 610-2 thereof), the following describes each part of the article management system 100 based on the block chain network.

The type of the blockchain network 200 is flexible and may be any one of, for example, a public blockchain (referred to as a public chain), a private blockchain (referred to as a private chain), or a federation blockchain (referred to as a federation chain). Taking a public link as an example, electronic devices such as user terminals and servers of any service entity can access the blockchain network 200 without authorization; taking a federation chain as an example, electronic devices (e.g., user terminals and servers) under the jurisdiction of a service entity after obtaining authorization may access the blockchain network 200, and at this time, the service entity may become a client node in the blockchain network 200.

In some embodiments, the client node may only act as an observer of the blockchain network 200, i.e., provide a function supporting the business entity to initiate a transaction (e.g., for uplink storage of data or query of data on a chain), and for functions of the consensus node 210 in the blockchain network 200, such as a ranking function, a consensus function, and an accounting function (e.g., a function of querying a status database), etc., the client node may be implemented by default or selectively (e.g., depending on the specific business requirements of the business entity), so that the data and business processing logic of the business entity may be migrated to the blockchain network 200 to the greatest extent possible, and the credibility and traceability of the data and business processing procedures are achieved through the blockchain network 200.

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

An exemplary application of the blockchain network is described below, taking an example in which a plurality of service entities access the blockchain network to implement service management of shared goods.

Referring to fig. 1, a plurality of business entities involved in a business management process for sharing an article according to an embodiment of the present invention, for example, a business entity 500 may be an article sharing party, a business entity 600 may be an article using party, and different business entities (for example, the business entity 500 and the business entity 600) respectively register with a Certificate Authority (CA) 400 to obtain respective digital certificates (including a public key of the business entity and a digital signature signed by the CA on the public key and identity information of the business entity), so as to be attached to a transaction together with a digital signature of the business entity for the transaction, and be sent to the blockchain network 200. Wherein after different service entities obtain authorization from the commodity sharing service management platform 300, a client running on a device (e.g., a user terminal or a server) of the service entity can request access from the blockchain network 200 to become a client node.

A service person of the service agent 500 logs in a client of the terminal 500-1, inputs user identity information, item information of an item to be shared, or a revenue query request, the user identity information, the item information of the item to be shared, or the revenue query request is sent to the item sharing service management platform 300, the item sharing service management platform 300 authenticates the user identity information, when the user identity information is authenticated, the item sharing service management platform 300 generates a transaction corresponding to an update operation or a query operation according to the item information or the revenue query request, specifies an intelligent contract to be invoked for realizing the update operation or the query operation in the transaction, and a parameter (for example, the identity information of the service agent 500) transferred to the intelligent contract, and carries a digital certificate of the service agent 500 and a signed digital signature (for example, using the private key of the digital certificate of the client of the terminal 500-1, the digest of the transaction is encrypted, where the service agent 500 may register with the certificate authority 400 to obtain the digital certificate), and broadcast the transaction to the consensus node 210 in the blockchain network 200.

When receiving a transaction, the consensus node 210 in the blockchain network 200 verifies the digital certificate and the digital signature carried in the transaction, and after both are successfully verified, confirms whether the business agent 500 has a transaction right according to the identity information of the business agent 500 carried in the transaction, and the transaction fails due to any verification result of the digital signature and the right verification. After the rights verification is successful, consensus node 210 signs its digital signature (e.g., by encrypting a digest of the transaction using the private key of consensus node 210-1) and continues to broadcast in blockchain network 200.

After receiving the transaction successfully verified, the consensus node 210 in the blockchain network 200 fills the transaction into a new block and broadcasts the new block. When broadcasting a new block, the consensus node 210 in the block chain network 200 performs a consensus process on the new block, and if the consensus is successful, adds the new block to the tail of the block chain stored in the consensus node, updates the state database according to the transaction result, and executes 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; and for the transaction of the income obtained by query, querying a key value pair corresponding to the income obtained from the state database, and returning a transaction result.

Similarly, a service person of the service agent 600 logs in a client of the terminal 600-2, inputs an article query request, the article query request is sent to the article sharing service management platform 300, the article sharing service management platform 300 generates a transaction corresponding to a query operation according to the article query request, specifies an intelligent contract required to be called for implementing the query operation and parameters transferred to the intelligent contract in the transaction, and also carries a digital certificate of the client of the terminal 600-2 and a signed digital signature (for example, a digest of the transaction is encrypted by using a private key of the digital certificate of the client of the terminal 600-2), and broadcasts the transaction to the consensus node 210 in the blockchain network 200.

When receiving a transaction, the consensus node 210 in the blockchain network 200 verifies the digital certificate and the digital signature carried in the transaction, and after both are successfully verified, confirms whether the service agent 600 has a transaction right according to the identity information of the service agent 600 carried in the transaction, and the transaction fails due to any verification result of the digital signature and the right verification. After the rights verification is successful, consensus node 210 signs its digital signature (e.g., by encrypting a digest of the transaction using the private key of consensus node 210-1) and continues to broadcast in blockchain network 200.

After receiving the transaction successfully verified, the consensus node 210 in the blockchain network 200 fills the transaction into a new block and broadcasts the new block. When broadcasting a new block, the consensus node 210 in the block chain network 200 performs a consensus process on the new block, and if the consensus is successful, adds the new block to the tail of the block chain stored in the consensus node, updates the state database according to the transaction result, and executes the transaction in the new block: and for the transaction of the items meeting the screening conditions, the key value pair corresponding to the items meeting the screening conditions is inquired from the state database, and the transaction result is returned.

It is understood that the type of data that can be queried/updated by the service entity in the blockchain network 200 can be implemented by restricting the right of a transaction that can be initiated by the service entity, for example, when the service entity 500 has the right of a transaction to initiate a query-obtained benefit, a service person of the service entity 500 can input a benefit query request in the graphical interface 510-1 of the terminal 500-1, generate a transaction for querying the obtained benefit by the goods sharing service management platform 300, and broadcast the transaction to the blockchain network 200 to obtain a corresponding benefit from the blockchain network 200;

when the service agent 600 has the right to initiate a transaction for querying the articles meeting the screening conditions, the service personnel of the service agent 600 may input an article query request in the graphical interface 610-2 of the terminal 600-2, generate a transaction for querying the articles meeting the screening conditions by the article sharing service management platform 300, and broadcast the transaction to the blockchain network 200 to obtain the corresponding articles meeting the screening conditions from the blockchain network 200.

As an example of a block chain, referring to fig. 2, fig. 2 is an optional structural schematic diagram of a block chain in a block chain network 200 according to an embodiment of the present invention, 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, a record of a newly generated transaction is filled in the block and is added to a tail of the block chain after being identified by a common node in the block chain network, so as to form a chain growth, and a chain structure based on hash values among blocks ensures tamper resistance and forgery prevention of transactions in the block.

An exemplary functional architecture of a blockchain network provided by an embodiment of the present invention is described below, referring to fig. 3, fig. 3 is a schematic diagram of an optional functional architecture of a blockchain network 200 provided by an embodiment of the present invention, where the blockchain network 200 includes an application layer 201, a consensus layer 202, a network layer 203, a data layer 204, and a resource layer 205, and functions of each layer are described below.

The resource layer 205 encapsulates computing, storage, and communication resources that implement each node 210 in the blockchain network 200, such as computing, storage, and communication resources in computers, servers/clusters, and clouds, abstracts and provides a uniform interface to the data layer 204 to shield the underlying hardware implementing the resource layer 205 from differences.

Computing resources include various forms of processors, such as Central Processing Units (CPUs), Application Specific Integrated Circuits (ASICs), and Field-Programmable Gate arrays (FPGAs).

The storage resources include various types of storage media such as various volatile memories and nonvolatile memories. The nonvolatile Memory may be a Read Only Memory (ROM) or a Programmable Read-Only Memory (PROM). Volatile Memory can be Random Access Memory (RAM), which acts as external cache Memory.

The communication resources include various communication links for communication between various nodes 210 in the blockchain network 200, between the blockchain network 200 and the traffic body.

The computing resources and storage resources of the resource layer 205 may be mapped to various types of nodes 210 in the blockchain network 200, and the storage medium implementing an embodiment of the present invention stores executable instructions for implementing the blockchain network-based article management method of an embodiment of the present invention, and once the executable instructions deployed to the nodes are executed, the underlying resources (e.g., various types of processors) implementing the nodes will implement the deployment of various types of nodes 210 in the blockchain network 200 and perform the functions of the various types of nodes, thereby implementing ledgers for transactions in business processes and various applications based on the ledgers.

By way of example, executable instructions may be written in any form of programming language, including compiled or interpreted languages, or declarative or procedural languages, in the form of software (including system programs and applications), software modules, scripts, plug-ins, and the like, and may be deployed in any form, including as a stand-alone program or as a module, component, or other unit suitable for use in a computing environment.

The data layer 204 encapsulates various data structures that implement the ledger, including blockchains implemented in files in a file system, state databases of the key-value type, and presence certificates (e.g., hash trees of transactions in blocks).

The network layer 203 encapsulates the functions of a Point-to-Point (P2P) network protocol, a data propagation mechanism and a data verification mechanism, an access authentication mechanism and service agent identity management.

Wherein, the P2P network protocol implements communication between each node 210 in the blockchain network 200, the data propagation mechanism ensures the propagation of the transaction in the blockchain network 200, and the data verification mechanism is used for implementing the reliability of data transmission between each node 210 based on cryptography methods (such as digital certificates, digital signatures, public/private key pairs); the access authentication mechanism is used for authenticating the identity of the service subject added into the block chain network 200 according to an actual service scene, and endowing the service subject with the authority of accessing the block chain network 200 when the authentication is passed; the business entity identity management is used to store the identity of the business entity that is allowed to access blockchain network 200, as well as the permissions (e.g., the types of transactions that can be initiated).

The consensus layer 202 encapsulates the functions of the mechanism for the nodes 210 in the blockchain network 200 to agree on a block (i.e., a consensus mechanism), transaction management, and ledger management. The consensus mechanism comprises consensus algorithms such as POS, POW and DPOS, and the pluggable consensus algorithm is supported.

The transaction management is configured to verify a digital signature carried in the transaction received by the node 210, verify identity information of the service entity, and determine whether the node has an authority to perform the transaction according to the identity information (read related information from the identity management of the service entity); for the service agents authorized to access the blockchain network 200, the service agents all have digital certificates issued by the certificate authority, and the service agents use private keys in their own digital certificates to digitally sign submitted transactions, so as to declare their own legal identities.

The ledger administration is used to maintain blockchains and state databases. For the block with the consensus, adding the block to the tail of the block chain; executing a transaction in the identified block, updating the key-value pair in the state database when the transaction comprises an update operation; and when the transaction comprises a query operation, querying the key-value pair in the state database, and returning a query result to the client of the business body. Supporting query operations for multiple dimensions of a state database, comprising: querying the chunk based on the chunk sequence number (e.g., hash value of the transaction); inquiring the transaction according to the transaction serial number; inquiring account data of a business main body according to an account (serial number) of the business main body; and inquiring the block chain in the channel according to the channel name.

The application layer 201 encapsulates various services that the blockchain network 200 can implement, including tracing, crediting, and verifying transactions.

For example, as an example of a software module, the memory 302 may include the article management device 40 based on the blockchain network provided by the embodiment of the present invention, which may be software in the form of a program, a plug-in, and the like, and include a series of software modules, see fig. 5, and fig. 5 is an optional schematic structural diagram of the article management device 40 based on the blockchain network provided by the embodiment of the present invention, for example, the article management device 40 based on the blockchain network includes a first receiving unit 41, an authenticating unit 42, a storing unit 43, a second receiving unit 44, a querying unit 45, and an authority transferring unit 46, and functions of these units are logical, so that any combination or further splitting may be performed according to functions implemented by each software module. It should be noted that, for the specific functions of each unit in the article management device 40 based on the blockchain network provided by the embodiment of the present invention shown in fig. 5, the following description will be made.

The following describes implementation of the article management method based on the blockchain network according to the embodiment of the present invention, with reference to an exemplary application and implementation of the blockchain network according to the embodiment of the present invention.

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

In step 601, the article sharing party logs in the article sharing service management platform to perform registration service.

In some embodiments, the registering of the article sharing party to the article sharing service management platform for registration service can be implemented as follows: the method comprises the steps that a business person of an 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 an article sharing service management platform, the article sharing service management platform carries out 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 service management platform, the business person can log in the article sharing service management platform and carry out corresponding registration service on the article sharing service management platform.

Here, the business person of the article sharing party is used to indicate a user who shares an article that is left unused by the user, and the shared article can be rented by others. The registration service includes registering at least one of the following information: personal information of a user sharing the item; item information of an item to be shared.

Wherein the personal information of the user sharing the item comprises at least one of the following information: the user identity information such as the name, identification number, mobile phone number, 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 fee. The article information of the article to be shared comprises basic information of the article to be shared, such as color, material, model and used fuel of the article to be shared, and also comprises 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, in response to the registration service of the item sharing party, user identity information uploaded by the first terminal corresponding to the item sharing party and item information of an item to be shared.

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

In some embodiments, referring to fig. 7, fig. 7 is another optional flowchart of the article management method based on the blockchain network according to the embodiment of the present invention, and based on fig. 6, the authentication of the user identity information in step 603 may also be implemented through the following steps 6031 to 6033, which will be described below with reference to the steps.

In step 6031, the goods sharing service management platform calls an interface of the authentication center to obtain the digital certificate of the goods 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 is verified, 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 present invention, the user identity information uploaded by the first terminal corresponding to the article sharing party may include signature information corresponding to the user identity information obtained by digitally signing the user identity information by the article sharing party. The following describes a process of implementing digital signature on user identity information by an article sharing party, specifically, firstly, the article sharing party extracts a summary of the user identity information based on a summary algorithm to obtain a summary value of the user identity information; then, the article sharing party encrypts the digest value of the user identity information by using a private key of the article sharing party to form corresponding signature information.

Here, the article sharing party may register with the certificate authority to obtain the digital certificate of the article sharing party before digitally signing the user identity information, and the certificate authority may generate a public-private key pair in the digital certificate of the article sharing party based on a key generation algorithm. The public and 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 improve the security of the key and to ensure the non-tamper-ability of the signature result, the key generation algorithm may preferably be an asymmetric key generation algorithm. The public key can pass verification in the block chain network and corresponds to the private key; the private key is used for the article 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 generally does not exist in the blockchain network, so as to ensure the security of the private key.

In some examples, the article sharing service management platform holds a public key of the certificate authority to verify a digital certificate sent by the article sharing party, when the verification is passed, the article sharing service management platform may extract the public key in the digital certificate of the article sharing party, where the public key is used to authenticate signature information of user identity information uploaded by a first terminal corresponding to the article sharing party, and when the verification is passed, the authenticity and reliability of the signature information of the uploaded user identity information are proved to be higher.

In some embodiments, before performing step 603, the method for article management based on a blockchain network may further include: requesting access permission for an 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 the embodiment of the present invention, the article sharing service management platform is deployed independently from the blockchain network, that is, the article sharing service management platform is an entity existing independently from the blockchain network. Therefore, in order to implement a scheme of article sharing by using a blockchain technology, participants in an article sharing service management process related in the embodiment of the present invention, such as an article sharing party, an article using party, and the like, need to obtain authorization of an article sharing service management platform before accessing to a blockchain network, otherwise, the participants in the article sharing service management process cannot access to the blockchain network without obtaining authorization of the article sharing service management platform.

In step 604, when the user identity information passes the authentication, the article sharing service management platform stores the article information of the article to be shared into the blockchain network.

In the embodiment of the invention, the item information of the item to be shared is stored in a key-value pair form, specifically, when the user identity information passes authentication, the item sharing service management platform combines the identification information of the item to be shared as a key and the encrypted item information as a value to form a key-value pair corresponding to the item information of the item to be shared, and sends a transaction carrying the key-value pair to a consensus node in a block chain network so as to store the key-value pair to the consensus node.

In some embodiments, referring to fig. 8, fig. 8 is another optional flowchart of the article management method based on the blockchain network according to the embodiment of the present invention, based on fig. 6, the storing of the article information of the article to be shared in step 604 in the blockchain network may be implemented through the following step 6041 and step 6042, which will be described below with reference to each step.

In step 6041, the article sharing service management platform sends the article information of the article to be shared to the blockchain network, so that the node of the blockchain network generates a new block corresponding to the article information of the article to be shared.

In step 6042, when the nodes providing the consensus service among the nodes of the blockchain network agree with the new block, the new block with the consensus is added to the end of the blockchain 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 an article to be shared and a version of an intelligent contract to be called; after receiving the data transaction request, the block chain network generates a new block corresponding to the article information of the article to be shared, signature information corresponding to the article information of the article to be shared is stored in the new block, when the article information of the article to be shared and the corresponding signature information reach a consensus by a plurality of nodes providing consensus service in the block chain network, the article sharing service management platform calls a corresponding intelligent contract according to the version of the intelligent contract to be called, and the article information of the article to be shared and the corresponding signature information are written into the block chain network by executing the intelligent contract.

In the embodiment of the invention, after the article sharing service management platform initiates a data transaction request to the blockchain network, each node in the blockchain network broadcasts a data transaction request sent by the goods sharing service management platform to the whole network, wherein, the data transaction request may be broadcast to the entire network in the form of P2P, at which time, a plurality of nodes in the blockchain network that provide consensus services vote for the item information of the item to be shared and the corresponding signature information, based on the consensus mechanism adopted by the blockchain network, when a transaction is agreed between a plurality of nodes providing a consensus service, for example, the agreement for voting reaches a set condition, the goods sharing service management platform may invoke the corresponding intelligent contract according to the version of the intelligent contract to be invoked, and writing the article information of the article to be shared and the corresponding signature information into the block chain network through the called intelligent contract. Because the blockchain network has the characteristics of being not tampered and being unremovable, the article information of the article to be shared and the corresponding signature information are stored in the blockchain network, and the safety and the reliability of the data stored in the blockchain network can be guaranteed.

In other embodiments, the article sharing service management platform may further store the article information of the article to be shared in 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 corresponding to the article information, and storing the hash value of the article information into the block chain network.

For example, the article information of the article to be shared may only include a small amount of text information, for example, the text information includes color, material, model, and the like of the article to be shared, and the article sharing service management platform may directly store the text information of the color, material, model, and the like of the article to be shared into the blockchain network. Of course, when the article information of the article to be shared includes large text information, for example, includes detailed description information of the article to be shared, the hash value of the text information included in the article information of the article to be shared may be determined, and the obtained hash value may be stored in the block chain network, so as to reduce the volume of the block chain.

In other embodiments, the article sharing service management platform may further store the article information of the article to be shared in the blockchain network in the following manner: determining text information included in original data representing article information, and storing the text information into a block chain network; determining multimedia information included in original data representing the article information, performing 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 a block chain network.

For example, the article information of the article to be shared may also include multimedia information, for example, the article information includes an image of the article to be shared, a 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 text information and multimedia information included in the article information of the article to be shared are separately stored in the blockchain network, so as to reduce the volume of the blockchain.

In step 605, the second terminal corresponding to the item user sends an item query request to the item sharing service management platform.

In the embodiment of the present invention, the item query 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 article to be used, which is set in the graphical interface by the article user, and the screening condition includes one or more of the following conditions: color, material, type, and (type of) fuel used, etc.; but also the location of the shared item to be used.

In step 606, the item sharing service management platform responds to the item query request, and queries items meeting the screening condition in the items to be shared from the block chain network.

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

In step 6061, the item query request is parsed to obtain the identifier of the query intelligent contract to be invoked and the screening condition.

In step 6062, the identifier 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 identifier of the query intelligent contract to be invoked, and queries the article that meets the screening condition and is in an unused state from the stored article information.

As an example of the item query request, the item query request carries an identifier of a query intelligent contract to be invoked and a screening condition, a corresponding query intelligent contract is executed by a consensus node in the blockchain network to query an item in the ledger state, which meets the screening condition and is in an unused state (for example, the second terminal corresponding to the item user may periodically locate the location information of the shared item to determine whether the shared item is used), and the location of the queried item is displayed in a graphical interface of the client of the second terminal. Here, the account book state may be queried according to the identifier of the article (the article information in the account book state is stored in a key-value pair form, which may improve the query efficiency, and of course, may also directly query the account book data), so as to query the article that meets the screening condition and is in an unused state.

In step 607, the article sharing service management platform transfers the usage right of the article meeting the screening condition from the first terminal to the second terminal, so that the second terminal can execute the usage right of the article meeting the screening condition.

In the embodiment of the present invention, the item shared by the item sharing party may refer to a device having a locking function and capable of releasing the locking state according to the unlocking code, and having a transportation and/or transportation function, such as a sharing bicycle. When the user of the second terminal arrives at the location of the displayed queried item, in order to ensure that the item to which the user of the second terminal has access rights is indeed the item shared in the blockchain network, before executing the use authority of the articles meeting the screening condition, the block chain network can be inquired about the article information of the articles to be used, 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, it can be determined that the user of the second terminal has indeed reached the correct location of the item to be used, and the subsequent second terminal can request consensus to obtain the unlock password by sending the item information corresponding to the queried item to the blockchain network, therefore, the locking state of the article can be 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 article sharing efficiency is ensured.

In the embodiment of the present invention, when the article is unlocked and the use by the article user is finished, for example, the article user using the shared article is triggered to finish the use in the client, or the article does not move beyond the waiting time, the following description will be made with reference to the accompanying drawings to collect the rental fee from the article user using the shared article and transfer the rental fee to the user account of the article sharing party.

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

In step 608, when it is detected that the articles meeting the screening condition start to be used, the payment interface is called to deduct the fee for the user account of the second terminal.

In step 609, when the end of the use of the article meeting the screening condition is detected, the deduction fee is checked based on the payment transaction rule of the article and the charging data of the article meeting the screening condition to determine the lease fee for using the article meeting the screening condition.

In step 610, the lease fee is transferred to the user account of the first terminal, and the use right of the article meeting the screening condition is transferred from the second terminal to the first terminal.

In some examples, the transferring of the lease fee to the user account of the first terminal may be implemented as follows: firstly, transferring the lease fee to 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 a payment transaction using articles meeting screening conditions; secondly, sending the payment transaction to a consensus node in the block chain network so that the consensus node can perform consensus on the payment transaction; and finally, when the consensus on the payment transaction passes, calling a collection intelligent contract in the consensus node to transfer the lease fee from the intermediate account to the user account of the first terminal.

Here, the article sharing service management platform calls a payment interface of a financial institution (e.g., a bank) corresponding to the second terminal, deducts a fee for a user account of the second terminal corresponding to an article user using the shared article, and transfers the user account to an intermediate account of a third-party financial institution, wherein 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. It should be noted that before deducting the fee for the user account of the second terminal, the article sharing service management platform may further send the identification information of the user of the article sharing party to the consensus node in the block chain network for identity verification, and when the verification is passed, the fee for the user account of the second terminal corresponding to the article user is deducted for the user account of the second terminal, so as to ensure the security of the fund.

Here, the pre-deduction fee is checked to determine how much the pre-deduction fee is made up, so as to transfer the lease fee to the intermediate account. As an example of the payment transaction, a consensus node in the blockchain network performs consensus on whether the lease fee is accurate according to the identifier of the user sharing the article, the identifier of the article, and the charging data, which are carried in the payment transaction. For example, the lease fee of the used article may be calculated according to the payment transaction rule of the article and by combining the charging data of the article meeting the screening condition (taking the shared article as the shared bicycle, the charging data is, for example, the driving distance and the driving time length), and the charging mode of the payment transaction rule of the article may be set by the article sharing party, or may be a uniform charging mode.

It should be noted that the consensus node in the block chain network acquires the identifier of the article meeting the screening condition from the payment transaction, queries the payment transaction rule stored in the uplink, determines the lease fee according to the charging data carried in the payment transaction, and signs the payment transaction if the lease fee is consistent with the lease fee carried in the payment transaction. When a sufficient number of the consensus nodes sign the payment transaction, the consensus on the payment transaction passes, and when the use of the article is finished, the consensus nodes in the block chain network run a collection intelligent contract to call a payment interface, and the lease fee is transferred from the intermediate account to the user account of the first terminal, so that the charge collection of the use of the shared article is completed. Of course, the charges transferred to the intermediate account need to be compensated according to the actual use charges.

In some embodiments, referring to fig. 11, fig. 11 is another optional flowchart of the method for article management 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 step 611 to step 613. The following will explain the steps.

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

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

In step 613, a notification message returned by the blockchain network is received, and the notification message is sent to the third terminal, so that the third terminal can maintain the item 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, the consensus request carries an identifier of a consensus intelligent contract and an identifier of an article to be maintained, the consensus node in the blockchain network executes the consensus intelligent contract, the state of an account book is inquired according to the identifier of the article to be maintained, whether the article to be maintained submitted by a third terminal corresponding to an article maintainer is consistent with information corresponding to the inquired article is verified, and if a sufficient number of consensus nodes (for example, more than half of the consensus nodes) determine to be consistent, the consensus passes, so as to generate a notification message indicating that maintenance is permitted.

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

In some examples, when the item to be maintained is maintained by the item maintainer, the maintenance cost may be deducted from the user account of the first terminal having the ownership of the shared item and the last terminal having the usage right of the shared item, such as the user account of the second terminal, and the maintenance cost is transferred to the user account of the third terminal.

Compared with the scheme of realizing 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, a block chain technology is introduced, and based on the decentralized characteristic of a block chain network, a user (including an article sharing party and an article using party) participates in the construction process of the whole shared article network, namely the user (the article sharing party) submits an article idle by the user to the block chain network for the renting of the user (the article using party) without completely depending on the restriction of a third-party platform, so that the operation efficiency of article sharing is improved; storing the article information of the article sharing party into the block chain 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 block chain network to ensure the safety and traceability of the article information; meanwhile, articles meeting the screening conditions are inquired from the block chain network for renting by an article user, so that the reliability of the article sharing process can be improved.

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

Before exemplary description of an application scenario of an embodiment of the present invention, description is made on a sharing scheme of articles of related art. Referring to fig. 12, fig. 12 is a flowchart illustrating an article sharing method provided in the related art, in which an facilitator (i.e., an operator providing an article sharing service) puts a large number of shared articles, such as shared bicycles, shared automobiles and other internet products, in different areas, and these large number of shared articles form a shared article pool, and when a user needs to use the shared articles provided by the facilitator, the shared articles can be preferentially selected from the shared article pool to directly use the selected shared articles.

Therefore, the shared economic products of the related art, such as the shared bicycle and the like, are short-term rental services provided by the service provider to the user, and the user purchases short-term usage rights of the goods to realize the sharing mode of the goods. However, the above-mentioned service provider operation method has several problems: firstly, a server needs to invest huge funds to construct a relatively perfect shared network, so that the operation cost is high, and a server used by the server for storing article information is easy to become an object of network attack, so that mutual distrust of article sharing participants is caused, and the reliability of the article sharing process is reduced; secondly, the lease scale and the coverage scale of the shared goods completely depend on the releasing force of the service provider, and the user participation degree is low, namely, the user can only lease goods provided by the service provider but cannot lease idle goods; third, for damaged shared goods, the service provider is required to perform maintenance in person, and the damaged shared goods may be distributed in different geographical locations, which results in high operation cost and low operation efficiency.

In order to solve at least the above technical problems of the related art, the method, the apparatus, the electronic device, and the storage medium for managing articles based on a blockchain network provided in the embodiments of the present invention can enable a user to participate in the whole process of constructing a shared article network by using the decentralized feature of the blockchain network, that is, the user can store an article left unused by the user into the blockchain network for renting by others, without completely relying on a sharing service of a service provider, thereby not only ensuring the security and traceability of article information, but also improving the operation efficiency of article sharing; meanwhile, the user can maintain any damaged article and collect certain expenses, so that the operation cost is greatly reduced, and the operation efficiency is improved.

Referring to fig. 13, fig. 13 is an optional schematic structural diagram of an article management method based on a blockchain network according to an embodiment of the present invention, where participants involved in an article management process according to an embodiment of the present invention include a user a (an article sharing party, i.e., a user sharing an article), a user B (an article using party, i.e., a user renting a shared article), and a user C (an article maintaining party, i.e., a user maintaining a damaged shared article), and an implementation process of an article management scheme based on a blockchain network according to an embodiment of the present invention is described below.

Firstly, a user A submits article information of an idle article (an article to be shared) of the user A 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 is passed, the article information of the idle article submitted by the user A is subjected to chain linking storage, namely the article information of the idle article submitted by the user A is stored in a block chain network, and after the article information is successfully chain linked, the block chain network distributes ownership and use right of the submitted idle article to the user A. Therefore, the user A submits the idle articles to the block chain network for others to rent, and charges corresponding rent fees, thereby not only protecting the information security of the shared articles, but also realizing the automation of the sharing and renting processes without manual intervention. The user a may upload the idle shared item through the interface shown in fig. 14, and also may submit the photo and the ownership certificate of the shared item. Here, when the user a submits the idle article, it must pay a certain maintenance fund for the subsequent maintenance of the shared article.

Next, when a user B needs to use an article shared by other users, a terminal corresponding to the user B sends an article query request to an article sharing service management platform, where the article query request is used to request to use a shared article stored on a chain and also needs to pay a certain deposit, and after receiving the article query request, the article sharing service management platform queries a block chain network in response to the article query request, receives a queried shared article meeting the screening condition of the user B returned by the block chain network, and transfers the right of use of the queried shared article from the user a to the user B, so that the user B can start to use the queried shared article after obtaining the right of use of the shared article, and when detecting that the use of the shared article by the user B is finished, deducts corresponding lease fees from the user account of the user B when the user B returns the article, and credit the rental fee to a user account that owns the ownership of the item, such as user a's user account. After the user B finishes using the shared article, the user B needs to return the usage right of the shared article to the user a.

In the process of article management, when a user C finds that a shared article is damaged, the user C may send an article maintenance request to an article sharing service management platform to request maintenance of the damaged shared article, where the article maintenance request carries an identifier of the article to be maintained, and the article sharing service management platform sends, in response to the article maintenance request, identifier information to the blockchain network so that a consensus node in the blockchain network agrees with the article to be maintained corresponding to the identifier information, and when the consensus node passes through the identifier, generates a notification message permitting maintenance, and after receiving the notification message returned by the blockchain network, the article sharing service management platform may send the notification message to the user C, so that the user C may perform maintenance of the article to be maintained, and when the user C completes the maintenance, the user C will use an account having the ownership of the article, that is the user account of the user a, and deducting corresponding maintenance cost from the last account with the use right of the article, namely the user account number of the user B in proportion, and classifying the maintenance cost into the user account number of the user C.

It should be noted that, the user a can query all the lent items and the corresponding earnings of the user a through the query interface shown in fig. 15, and the earning interface shown in fig. 15 is used to achieve the purpose of earning the earnings of the rented shared items by one key. When there is no user using the shared article of the user a, or the user a wants to use the shared article by himself or herself, the purpose of retrieving the shared article can be achieved through the interface for retrieving the shared article shown in fig. 14.
