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 hang transaction, a buy transaction, etc. to the nodes. 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.
In some possible embodiments, a node 101 of the blockchain network may obtain a hang transaction submitted by a first user through a first terminal device 102, the hanging-disk transaction includes the quantity and price of the target virtual resource to be traded, if a purchase transaction submitted by a second user for the target virtual resource through the second terminal device 103 is received, node 101 invokes the smart contract to lock the target virtual resource and sends a payment link for the target virtual resource to the second terminal device, after the intelligent contract detects that the second user completes payment by using the payment link, the node 101 transfers the target virtual resource from the account of the first user to the account of the second user, therefore, the transaction of the virtual resources can be completed quickly and efficiently through the block chain, and the safety is effectively ensured.
In some possible embodiments, a certain node 101 of the blockchain network may broadcast the onboarding transaction and the buy transaction to other nodes in the blockchain network, and after the other nodes verify the consensus of the onboarding transaction and the buy transaction, the node 101 writes the onboarding transaction and the buy transaction into a block, so that each transaction record can be linked up, thereby effectively preventing tampering and ensuring the validity and traceability of transaction data.
In some possible implementations, taking the virtual resource as a bond as an example, referring to fig. 1d, a basic business process of bond transaction provided by an embodiment of the present invention specifically includes: the method comprises the steps that a seller submits a reel hanging transaction to a blockchain network aiming at bond assets to be sold, a buyer submits a buying transaction aiming at the reel hanging transaction of the seller, an intelligent contract of the blockchain network automatically matches the transactions of the buyer and the seller, the bond assets on a chain hung by the seller are transferred to an account of the buyer after matching is successful, the bond transaction record is written into a block in the blockchain, and the bond transaction record can be sent to a bond registration center for registration.

201. the node acquires a hanging disc transaction submitted by a first user through a first terminal device, wherein the hanging disc transaction comprises the quantity and the price of a target virtual resource to be traded.
The virtual resource related in the embodiment of the present invention may specifically include securities such as bonds.
Specifically, the first user may refer to a user who wants to sell a virtual resource, and then the first user is a seller at this time, the first terminal device may be accessed to the blockchain network, a node in the blockchain network may receive a hanging transaction submitted by the first user through the first terminal device, and may broadcast the hanging transaction to other nodes in the blockchain network, and the other nodes record the hanging transaction after passing through consensus verification on the hanging transaction, and the hanging transaction may include the number of target virtual resources to be traded (i.e., the amount of virtual resources that the first user wants to sell), and a price, taking a bond as an example, and the hanging transaction may include the number of bonds to be traded and a price of each bond, for example, 10 a bonds are sold, and the price is 100 yuan per bond.
202. And if the node acquires the purchase transaction submitted by the second user for the target virtual resource through the second terminal equipment, calling an intelligent contract to lock the target virtual resource, and sending a payment link for the target virtual resource to the second terminal equipment.
Specifically, the second user is a user who wants to buy the virtual resource, and the second user is a buyer at this time, and may access the second terminal device to the blockchain network to inquire about a hanging transaction submitted by other users, and if the second user is interested in a target virtual resource in the hanging transaction submitted by the first user and wants to buy the target virtual resource, a node in the blockchain network may receive a buying transaction submitted by the second user through the second terminal device, and after receiving the buying transaction, the node may invoke an intelligent contract to lock the target virtual resource, generate a payment link for the target virtual resource, and then send the payment link to the second terminal device, where the payment link is used for the second user to pay for buying the target virtual resource.
It should be noted that the node that receives the dial-up transaction submitted by the first user through the first terminal device and the node that receives the purchase transaction submitted by the second user through the second terminal device may be the same node in the blockchain network or different nodes in the blockchain network, which is not limited in the embodiment of the present invention.
203. And after the intelligent contract detects that the second user completes payment by using the payment link, the node transfers the target virtual resource from the account of the first user to the account of the second user.
Specifically, the second terminal device may display the payment link, the second 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 second user, and when a payment success notification returned by the payment platform is detected, the second user is confirmed to complete payment, and the target virtual resource is transferred from an account of the first user to an account of the second user, so as to complete a quick transaction of the virtual resource, where the account of the first user and the account of the second user are block chain accounts registered in advance, and a T +0 quick transaction of virtual resources such as bonds and the like may be achieved through the block chain.
In some possible embodiments, a user may uplink a virtual asset held by the user in a trading market outside a blockchain, and when receiving a virtual asset uplink request of the user, a node may obtain a virtual resource holding amount of a first user and a virtual resource holding amount of a second user, create accounts (i.e., blockchain accounts) for the first user and the second user respectively, then bind the virtual resource holding amount of the first user to the account of the first user, bind the virtual resource holding amount of the second user to the account of the second user, and write an uplink record of a virtual resource of the user into the blockchain after the common identification verification of other nodes passes, so that the user may subsequently perform a virtual resource transaction through the blockchain.
In some possible embodiments, the node, after sending the payment link for the target virtual resource to the second terminal device, the smart contract may be invoked to detect a payment status of a payment made by the second user using the payment link, if the payment is not completed within a preset time period (e.g., 10 minutes), the node may deduct a preset first amount (e.g., 1 minimum transaction unit) or a preset first proportion (e.g., 0.005% of the target virtual resource) of the virtual resource from the account of the second user, the deducted virtual resource (i.e., the on-chain asset) may be transferred to the current node's account as a reward for providing computing power to the node, and the target virtual resource may be unlocked, visually, if the user is not paid for the virtual resource over time, the node may automatically deduct a portion of the commission from its account to use as a penalty to the second user.
In some possible embodiments, before the node locks the target virtual resource for the second user, the node may invoke the smart contract to deduct a preset second amount (e.g., 2 minimum transaction units) or a preset second proportion (e.g., 0.01% of the target virtual resource) of the virtual resource from the account of the second user, that is, deduct a commission fee corresponding to the purchase transaction from the on-chain asset, and then lock the target virtual resource for the second user.
In summary, the on-chain assets (i.e. the held virtual resources) of the user are only used for paying the procedure cost in the transaction process, and the cost corresponding to the purchase and sale is completed by walking through the bank payment system by the intelligent contract.
In some possible embodiments, after the intelligent contract detects that the second user completes payment by using the payment link, the specific implementation manner of the node transferring the target virtual resource from the account of the first user to the account of the second user may be: after the intelligent contract detects that the second user completes payment by using the payment link, the node generates a transaction (marked as a transfer transaction of the target virtual resource), wherein the transfer transaction of the target virtual resource may specifically include the following data: the account address of a first user (namely a seller), the account address of a second user (namely a buyer), the amount of a target virtual resource, the transfer direction of the target virtual resource (namely, the transfer from the account of the first user to the account of the second user), the transfer time, the transaction price, the subscription fee and the commission charge amount paid by the second user, and the like, and broadcasts the transfer transaction of the target virtual resource to other nodes in the block chain network for verification, after the other nodes verify the common identification of the transfer transaction of the target virtual resource, the target virtual resource is transferred from the account of the first user to the account of the second user, and writes the transfer transaction of the target virtual resource into a block, and also broadcasts the block to other nodes in the block chain network, and after the other nodes verify that the block is legal, the block is added into an own account book, thereby completing the convenient transaction of the virtual resource, and the resource transfer record uplink is not tampered.
In some possible embodiments, after transferring the target virtual resource from the account of the first user to the account of the second 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 a transfer direction of the target virtual resource, that is, the target virtual resource is transferred from the account of the first user to the account of the second user, so that the transaction record is also recorded at a position other than the blockchain, thereby facilitating subsequent verification of the transaction record between users.
In some possible embodiments, the node may also perform uplink operations on onboarding and buy transactions, namely: the node broadcasts the hanging plate transaction and the buying transaction to other nodes, wherein the hanging plate transaction specifically comprises the following data: the account address of the first user (i.e. the seller), the amount of the target virtual resource to be traded, the price, the listing time, etc., and the purchase transaction may specifically include the following data: after the other nodes verify that the block is legal, the block is added into an account book of the second user, so that the user behaviors such as the hanging transaction and the buying transaction are recorded and linked up and cannot be tampered.
