Aiming at the problems of complicated flow, poor safety and the like commonly existing in virtual resources such as bond issuing at present, the embodiment of the invention provides a resource management method based on a block chain network, which can conveniently and efficiently issue the virtual resources through the block chain and effectively ensure the data safety.

Referring to fig. 1a, it is a schematic structural diagram of a resource management system provided in an embodiment of the present invention, where the resource management system includes a blockchain network 10, a first terminal device 102, and a second terminal device 103, where:

the blockchain network 10 refers to a network for performing data sharing between nodes, and a plurality of nodes 101 may be included in the blockchain network. Each node 101 may receive input information and maintain shared data (i.e., blockchains) within the blockchain network based on the received input information while operating normally. In order To ensure information intercommunication in the blockchain network, each node may have information connection, and any two nodes may implement Peer-To-Peer (P2P) communication, and specifically may perform P2P communication through a wired communication link or a wireless communication link. For example, when any node in the blockchain network receives input information, other nodes acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes in the blockchain network are consistent.

The first terminal device 102 and the second terminal device 103 may access the blockchain network and may communicate with nodes in the blockchain network, for example, initiate a service request to a node, obtain data from a node, and so on. The first terminal device 102 and the second terminal device 103 may be a smart phone, a tablet computer, a notebook computer, a desktop computer, a vehicle-mounted smart terminal, and the like.

It should be noted that the number of nodes shown in fig. 1a is only schematic, and any number of nodes may be deployed according to actual needs, and the first terminal device 102 and the second terminal device 103 may communicate with the same node in the blockchain network or communicate with different nodes in the blockchain network respectively.

Each node in the blockchain network has a corresponding node identifier, and each node in the blockchain network can store node identifiers of other nodes in the blockchain network, so that the generated block can be broadcast to other nodes in the blockchain network according to the node identifiers of other nodes. Each node may maintain a node identifier list as shown in the following table, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an Internet Protocol (IP) address or any other information that can be used to identify the node, and the table is described by taking the IP address as an example.

Node name	Node identification
		Node 1	117.114.151.174
Node 2	117.116.189.145
		…	…
Node N	119.123.789.258

Each node in the blockchain network stores one identical blockchain. The block chain is composed of a plurality of blocks, referring to fig. 1b, the block chain is composed of a plurality of blocks, the starting block comprises a block head and a block main body, the block head stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.

When each block in the block chain is generated, referring to fig. 1c, when a node where the block chain is located receives input information, the input information is verified, after the verification is completed, the input information is stored in a memory pool, and a hash tree used for recording the input information is updated; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:

SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET

wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.

Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. And then, the node where the block chain is located respectively sends the newly generated blocks to other nodes in the block chain network where the newly generated blocks are located according to the node identifications of the other nodes in the block chain network, the newly generated blocks are verified by the other nodes, and the newly generated blocks are added to the block chain stored in the newly generated blocks after the verification is completed.

The intelligent contract can be operated on the nodes of the block chain network, the intelligent contract is realized by codes executed when a certain condition is met, developers can define contract logic through a programming language, issue the contract logic to the block chain (intelligent contract registration), and call keys or other events to trigger execution according to the logic of contract terms to complete the contract logic and simultaneously provide the functions of upgrading and cancelling the intelligent contract.

please refer to fig. 2, which is a flowchart illustrating a resource management method based on a blockchain network provided by the resource management system shown in fig. 1a according to an embodiment of the present invention, where the resource management method based on a blockchain network according to an embodiment of the present invention is mainly described from a node side, the blockchain network includes a plurality of nodes, and the resource management method based on a blockchain network includes the following steps:

201. the node receives a virtual resource issuing request sent by an issuer through first terminal equipment, wherein the virtual resource issuing request carries characteristic information of the issuer and a virtual resource issuing plan.

The issuer may be an issuer of an enterprise, a country, or the like, the virtual resource may specifically include securities such as bonds, and the node may be any one of a plurality of nodes included in the block chain network.

Specifically, when the issuer needs to issue the virtual resource, the first terminal device may be accessed to the blockchain network, a node in the blockchain network may receive a virtual resource issuance request sent by the issuer through the first terminal device, and the virtual resource issuance request carries characteristic information of the issuer and a virtual resource issuance plan, where the characteristic information of the issuer may include data capable of reflecting credit and reimbursement capability of the issuer, such as name of the issuer, taxpayer identification number, business data and financial data, and the virtual resource issuance plan may include an issuance total, unit price, number of sheets, and reimbursement period.

202. The node generates a virtual resource issuance transaction according to the issuer characteristic information and the virtual resource issuance plan, and broadcasts the virtual resource issuance transaction to other nodes of the plurality of nodes.

Specifically, after receiving a virtual resource issuance request sent by a first terminal device, a node may generate a transaction (denoted as a virtual resource issuance transaction) according to the characteristic information of an issuer and a virtual resource issuance plan carried in the virtual resource issuance request, and broadcast the virtual resource issuance transaction to other nodes in the blockchain network for verification, where the virtual resource issuance transaction may specifically include the following data: the name of the issuer, the type of the virtual resource, the total amount of issuance, unit price, number of sheets, repayment period, subscription channel, etc.

203. And after the other nodes pass the verification of the consensus of the virtual resource issuance transaction, the node writes the virtual resource issuance transaction into a block so as to complete the issuance of the virtual resource.

Specifically, after the consensus algorithm is used by other nodes to verify the consensus of the virtual resource issuance transaction, the node may write the virtual resource issuance transaction into the block, broadcast the block to other nodes in the block chain network, and add the block into its own account book after the other nodes verify that the block is legal, thereby completing issuance of the virtual resource.

In some possible embodiments, after receiving the virtual resource issuance request, the node may review the virtual resource issuance request, which may specifically include: the node calls an intelligent contract to check the virtual resource issuing request, wherein the intelligent contract indicates the issuing condition of the virtual resource, when the checking result of the intelligent contract indicates that the characteristic information of the issuer and the virtual resource issuing plan meet the issuing condition, the node can generate a virtual resource issuing transaction for the characteristic information of the issuer and the virtual resource issuing plan, and the check of the virtual resource issuing request can effectively avoid the issuing of low-quality virtual resource and ensure the reliability of the issued virtual resource. Wherein the intelligent contract may be run on a virtual machine of each of a plurality of nodes included in the blockchain network.

Please refer to fig. 3, which is a flowchart illustrating another resource management method based on a blockchain network provided by the resource management system shown in fig. 1a according to an embodiment of the present invention, where the resource management method based on a blockchain network according to an embodiment of the present invention is mainly described from a node side, the blockchain network includes a plurality of nodes, and the resource management method based on a blockchain network includes the following steps:

301. the node receives a virtual resource issuing request sent by an issuer through first terminal equipment, wherein the virtual resource issuing request carries characteristic information of the issuer and a virtual resource issuing plan.

302. The node generates a virtual resource issuance transaction according to the issuer characteristic information and the virtual resource issuance plan, and broadcasts the virtual resource issuance transaction to other nodes of the plurality of nodes.

303. And after the other nodes pass the verification of the consensus of the virtual resource issuance transaction, the node writes the virtual resource issuance transaction into a block so as to complete the issuance of the virtual resource.

The specific implementation of steps 301 to 303 can be referred to the specific description of steps 201 to 203 in the foregoing embodiments, and will not be described herein again.

304. And the node acquires a virtual resource acquisition request submitted by a user through the second terminal equipment, wherein the virtual resource acquisition request carries the number of the virtual resources.

Specifically, after the virtual resource of the issuer is issued in uplink, the user (i.e., the subscriber) may subscribe to the issued virtual resource, access the second terminal device to the blockchain network, and obtain, by a node in the blockchain network, a virtual resource obtaining request submitted by the user through the second terminal device, where the virtual resource obtaining request carries a virtual resource quantity, which is a virtual resource quantity that the user wants to subscribe to, and takes a bond as an example, and the virtual resource quantity may specifically refer to the number of bonds or the value of the bond.

It should be noted that the node receiving the virtual resource acquisition request and the node receiving the virtual resource issuance request may be the same node in the blockchain network or different nodes in the blockchain network, and the embodiment of the present invention is not limited thereto.

305. And the node calls an intelligent contract to lock the target virtual resources corresponding to the virtual resource quantity, and sends a payment link aiming at the target virtual resources to the second terminal equipment.

Specifically, after the user submits the virtual resource acquisition request, the node locks the target virtual resource matched with the amount of the virtual resource that the user wants to subscribe to by using the intelligent contract, generates a payment link for the target virtual resource, and then sends the payment link to the second terminal device, wherein the payment link is used for the user to pay for subscribing to the target virtual resource.

306. And after the intelligent contract detects that the user completes payment by using the payment link, the node transfers the target virtual resource to the account of the user.

Specifically, the second terminal device may display the payment link, the user may jump to a payment platform (e.g., a unionpay or a third-party payment mechanism) to pay the fee by clicking the payment link, the intelligent contract of the node may detect a payment state of the user, and when a payment success notification returned by the payment platform is detected, the user is confirmed to complete payment, and the target virtual resource is transferred to an account of the user, so as to complete subscription of the virtual resource, where the account of the user is a block chain account registered by the user in advance.

In some possible embodiments, the virtual resource acquisition request submitted by the second terminal device further carries a commission amount, that is, a fee that the user is willing to pay in addition to preferentially subscribe to the virtual resource, and the specific way for the node to invoke the intelligent contract to lock the target virtual resource corresponding to the virtual resource quantity may be: the node acquires the submission time and the commission amount of the virtual resource acquisition request, and then determines the locking priority of the user on the target virtual resource by calling an intelligent contract according to the submission time and the commission amount, wherein the earlier the submission time is, the higher the commission amount willing to be paid additionally is, the higher the locking priority on the target virtual resource is, which means that the target virtual resource can be subscribed preferentially, so that the node locks the target virtual resource by calling the intelligent contract according to the determined locking priority.

In some possible embodiments, after the node sends the payment link for the target virtual resource to the second terminal device, the node may invoke a smart contract to detect a payment status of the user for making a payment by using the payment link, if the payment status indicates that the payment is not completed within a preset time (e.g., 15 minutes or 30 minutes), the node may deduct a preset amount or a preset proportion of the virtual resource from an account of the user, transfer the deducted virtual resource to the account of the current node as a reward for providing computing power to the node, and unlock the target virtual resource, and it is seen that if the user does not pay for a timeout while subscribing the virtual resource, the node may automatically deduct a part of the commission charge from the account of the user as the reward.

In some possible embodiments, after the intelligent contract detects that the user completes payment by using the payment link, the specific implementation manner of the node transferring the target virtual resource to the account of the user may be: after the intelligent contract detects that the user completes payment by using the payment link, a transaction (marked as a transfer transaction of the target virtual resource) is generated, where the transfer transaction of the target virtual resource may specifically include the following data: the method comprises the steps that an account address of a user (namely a subscriber), the number of target virtual resources, paid subscription fees, commission amount, transfer time and the like are broadcasted to other nodes in a block chain network for verification, the target virtual resources are transferred to the account of the user after the other nodes verify the transfer transaction consensus of the target virtual resources, the transfer transaction of the target virtual resources is written into a block, the block needs to be broadcasted to other nodes in the block chain network, and the block is added into an account book of the user after the other nodes verify the validity of the block, so that the transfer of the virtual resources is completed, the subscription of the virtual resources by the user is realized, and the uplink and the non-tampering of the subscription record are realized.

In some possible embodiments, after the node transfers the target virtual resource to the account of the user, the node may send a transfer transaction of the target virtual resource to the virtual resource registration center, so that the virtual resource registration center records information such as that the target virtual resource has been subscribed, a corresponding subscriber, subscription time, and the like, so that the subscription record is also recorded at a position other than the blockchain, thereby facilitating subsequent verification of the user subscription record.

In the embodiment of the present invention, a node may receive a virtual resource issuance request sent by an issuer through a first terminal device, where the virtual resource issuance request carries characteristic information and a virtual resource issuance plan of the issuer, and may generate a virtual resource issuance transaction for the characteristic information and the virtual resource issuance plan of the issuer, and then broadcast the virtual resource issuance transaction to other nodes in a block chain network, and after the other nodes verify the consensus of the virtual resource issuance transaction, the node writes the virtual resource issuance transaction into a block to complete issuance of a virtual resource, further, the node may further obtain a virtual resource acquisition request submitted by a user through a second terminal device, where the virtual resource acquisition request carries the number of virtual resources, and locks a target virtual resource corresponding to the number of virtual resources by invoking an intelligent contract, and sending a payment link to the second terminal device, and transferring the target virtual resource to an account of the user after the intelligent contract detects that the user completes payment by using the payment link, so that the virtual resource is issued conveniently and efficiently by an asset issuing uplink mode, the user can perform quick subscription on the virtual resource through the block link, and issue records and subscribe records uplink, so that data cannot be tampered, and the safety is effectively ensured.
