Before explaining the resource distribution method based on the block chain provided by the embodiment of the present application, relevant contents of the block chain are explained first.
Fig. 1 is a schematic structural diagram of a data sharing system (also referred to as a blockchain system) according to an embodiment of the present disclosure. Referring to fig. 1, a data sharing system 100 refers to a system for performing data sharing between nodes, the data sharing system 100 may include a plurality of nodes 101, and the plurality of nodes 101 may refer to respective clients in the data sharing system 100. Each node 101 may receive input information and maintain shared data within the data sharing system 100 based on the received input information while operating normally. In order to ensure information intercommunication in the data sharing system 100, an information connection may exist between each node 101 in the data sharing system 100, and information transmission may be performed between the nodes 101 through the information connection. For example, when an input information is received by any node 101 in the data sharing system 100, other nodes 101 in the data sharing system 100 acquire the input information according to the consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes 101 in the data sharing system 100 are consistent.
Each node 101 in the data sharing system 100 has a node identifier corresponding thereto, and each node 101 in the data sharing system 100 may store the node identifiers of other nodes 101 in the data sharing system 100, so that the generated block is broadcast to other nodes 101 in the data sharing system 100 according to the node identifiers of other nodes 101. Each node 101 may maintain a node identifier list as shown in table 1 below, and store the node name and the node identifier in the node identifier list correspondingly. The node identifier may be an IP (Internet Protocol) address and any other information that can be used to identify the node 101, and only the IP address is taken as an example in table 1 for description.
TABLE 1
| Node name | Node identification |
| Node 1 | 117.114.151.174 |
| Node 2 | 117.116.189.145 |
| …… | …… |
| Node N | 119.123.789.258 |
Note that, in the embodiments of the present application, the node identifier list is described only by taking table 1 as an example, and table 1 does not limit the embodiments of the present application.
Each node 101 in the data sharing system 100 stores one and the same blockchain. The block chain is composed of a plurality of blocks, referring to fig. 2, the block chain is composed of a plurality of blocks, the starting block includes a block header and a block main body, the block header 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. 3, when the node where the block chain is located receives the input information, the input information is verified, after the verification is completed, the input information is stored in the memory pool, and the hash tree 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. Subsequently, the node where the block chain is located sends the newly generated blocks to other nodes 101 in the data sharing system 100 where the newly generated blocks are located respectively according to the node identifiers of the other nodes 101 in the data sharing system 100, the newly generated blocks are verified by the other nodes 101, and the newly generated blocks are added to the block chain stored by the newly generated blocks after the verification is completed.
The following describes a block chain system related to embodiments of the present application.
Fig. 4 is a block chain system according to an embodiment of the present disclosure. Referring to fig. 4, the blockchain system may include a plurality of node servers and resource distribution servers. The plurality of node servers are servers of a plurality of nodes in a supply chain, and the resource issuing server is a server of a resource issuing authority. Each server of the plurality of servers included in the blockchain system is a blockchain node.
It should be noted that a plurality of nodes may be included in the supply chain, such as a core node, a level one node, a level two node, … …, a level N node, etc., each node having a node server. The terminal of each node may communicate with the server of the node via a wireless or wired network. The core node is a large-scale and credit-good node in the supply chain, such as a large nationally owned enterprise with sufficient funds. The primary node, the secondary node, … …, the N-level node, etc. are nodes that have direct or indirect transaction with the core node, such as medium and small micro-enterprises such as primary suppliers, secondary suppliers, tertiary suppliers, ·.
In addition, the resource issuing authority has a resource issuing server, and a terminal of the resource issuing authority can communicate with the resource issuing server through a wireless network or a wired network. The resource issuing authority is an authority capable of issuing resources, such as a financial company, which may be a commercial bank, a credit company, and the like. Nodes in the supply chain can apply for resources from the resource issuing organization when a resource gap occurs, for example, a supplier in the supply chain can apply for financing from a finance company when a fund gap occurs.
The node in the supply chain may uplink store its own resource indication information, that is, send its own resource indication information to its node server, and the node server stores the resource indication information into the blockchain configured in the blockchain system. The resource issuing server can determine the resource issuing risk value according to the resource indication information stored in the self-configured block chain and send the resource issuing risk value to the resource issuing mechanism. And the resource issuing mechanism can issue the resources to the nodes in the supply chain according to the resource issuing risk value.
Next, a resource distribution method based on a block chain provided in the embodiment of the present application is explained in detail.
Fig. 5 is a flowchart of a method for resource allocation based on a blockchain according to an embodiment of the present disclosure, where the method is applied to the blockchain system shown in fig. 4, an execution subject of the method may be a node server in one or more groups, where one or more blockchains are configured in the node server, and the one or more blockchains are in one-to-one correspondence with the one or more groups. Referring to fig. 5, the method may include the steps of:
step 501: the node server receives the resource indication information sent by the node terminal.
It should be noted that the node server is a server of any node in the supply chain, and the node terminal is a terminal of the node. Nodes in the supply chain are participants in supply chain commerce and may include core enterprises, suppliers, and the like.
In addition, the resource indication information may be used to indicate a resource status of the node to reflect the credit strength of the node, for example, the resource indication information may be a contract, a ticket, a fixed resource quantity, and the like, which is not limited in this embodiment of the present application.
For example, when the resource indication information is a contract, the name, amount and date of the contract may be first entered through a contract information upload page as shown in fig. 6, and then the contract is uploaded to the node terminal, and the node terminal sends the contract to the node server.
For another example, when the resource indication information is a ticket, the name and the amount of the ticket may be first entered through a ticket information upload page as shown in fig. 7, and then the ticket is uploaded to the node terminal, and the node terminal sends the contract to the node server.
It should be noted that, while sending the resource indication information to the node server, the node terminal may also send a group identifier to the node server to indicate a group to be shared by the resource indication information in the blockchain system. The group id may be used to identify a group, for example, the group id may be a name of the group.
Step 502: the node server generates a block according to the resource indication information, wherein the block is used for storing the resource indication information.
Specifically, the node server may extract at least one node identifier included in the resource indication information. The node server generates a block in which the resource indication information is stored, and correspondingly stores the identifier of the block and the at least one node identifier; or, generating a block storing the resource indication information and the at least one node identifier.
It should be noted that the node identifier is used to identify the identity of the node, for example, the node identifier may be a name of the node. The at least one node identifier included in the resource indication information is an identifier of each of the at least one node to which the resource indication information relates. For example, when the resource indication information is contract, at least one node identifier included in the resource indication information is an identifier of two or more nodes signing for the contract; when the resource indication information is a bill, at least one node identifier contained in the resource indication information is an identifier of a node issuing the bill; when the resource indication information is the fixed resource quantity, at least one node identifier included in the resource indication information is the identifier of the node to which the fixed resource with the fixed resource quantity belongs.
In addition, the identification of the block may be a memory address of the block, etc. The block can be found according to the identification of the block, and then the data stored in the block is obtained.
Wherein the node server extracting at least one node identifier contained in the resource indication information may be implemented using an OCR (Optical Character Recognition) technique. Of course, other technologies may be used to implement the method, and the embodiment of the present application is not limited thereto.
It should be noted that OCR technology may include processes of image input, image preprocessing, character positioning, character recognition, and the like. For example, when the node server extracts at least one node identifier included in the resource indication information by using an OCR technology, the node server may obtain an image of the resource indication information; preprocessing the image such as binarization, noise removal, inclination correction and the like; locating a character in the image; and identifying characters in the image by using a template matching or feature extraction method so as to obtain at least one node identifier contained in the resource indication information.
Further, before step 502, the node server may further determine the type of the resource indication information, detect whether the resource indication information is true or false according to the type of the resource indication information, and then execute step 502 when the resource indication information is true.
It should be noted that the type of the resource indication information may include a ticket type, a transaction type, and the like. The bill type can be invoice vouchers of fixed resources purchased by the node, tax payment vouchers of the node and the like; the transaction type may be contract credentials signed between nodes, etc.
In addition, when the resource indication information has authenticity, the node server generates a block for the resource indication information. When the resource indication information does not have authenticity, the node server indicates that the resource indication information is unreliable, and at this time, the node server may not generate a block for the resource indication information and directly end the operation.
The node server may detect whether the resource indication information is true or false according to the type of the resource indication information, where the operation of detecting whether the resource indication information is true may include the following two possible implementation manners:
a first possible implementation: when the type of the resource indication information is a bill type, the node server extracts an information code in the resource indication information; and detecting the authenticity of the resource indication information according to the information code.
The information code is a code given to the resource indication information by an authority such as a tax authority, and may be a string of numbers or letter codes. For example, when the resource indication information is an invoice certificate of a node purchasing a fixed resource or a tax payment certificate of the node, the information code may be a code of the invoice certificate or the tax payment certificate.
The operation of extracting the information code in the resource indication information by the node server is similar to the operation of extracting at least one node identifier included in the resource indication information by the node server, which is not described in detail in this embodiment of the present application.
When the node server detects the authenticity of the resource indication information according to the information code, the node server can send a verification request carrying the information code to a designated server; after receiving a verification success message returned by the appointed server, determining that the resource indication information has authenticity; and when receiving the authentication failure message returned by the specified server, determining that the resource indication information does not have authenticity.
It should be noted that the designated server is a server for distributing the information code, for example, the designated server may be an authoritative server, and thus the designated server may identify whether an information code is authentic. When the designated server stores the information code, the information code can be determined to be real, and at the moment, a verification success message is returned to the node server to indicate that the resource indication information has authenticity; when the information code is not stored in the designated server, it may be determined that the information code is not authentic, and at this time, an authentication failure message may be returned to the node server to indicate that the resource indication information does not have authenticity.
A second possible implementation: when the type of the resource indication information is a transaction type, the node server extracts at least two node identifications contained in the resource indication information; and sending the resource indication information to the node terminals corresponding to the at least two node identifications so as to indicate the node terminals to detect the authenticity of the resource indication information.
It should be noted that, when the resource indication information is information including transaction contents such as a contract, the type of the resource indication information is a transaction type, and at this time, the resource indication information includes at least two node identifiers, and the resource indication information relates to at least two nodes, so that the at least two nodes can identify the authenticity of the resource indication information. Therefore, the node server can send the resource indication information to the node terminals corresponding to the at least two node identifiers to indicate the node terminals to detect the authenticity of the resource indication information.
Further, after the node server sends the resource indication information to the node terminals corresponding to the at least two node identifiers, and after receiving a verification success message returned by the node terminals, the node server determines that the resource indication information has authenticity; and when receiving the authentication failure messages returned by the node terminals, determining that the resource indication information does not have authenticity.
It should be noted that, when receiving the resource indication information, the node terminal may generate a reminding message to remind the user to confirm the authenticity of the resource indication information. When the node terminal detects the confirmation operation of the reminding message, the resource indication information is determined to be true, and a verification success message is generated and returned to the node server. And when the node terminal detects the denial operation of the reminding message, determining that the resource indication information is not true, generating a verification failure message and returning the verification failure message to the node server.
Step 503: the node server determines a target group allowing the resource indication information to be shared from one or more groups in which the node server is located, wherein the target group comprises other node servers and a resource issuing server.
It should be noted that the node servers may be in one or more groups. In a possible implementation manner, one or more groups in which the node server is located may be determined according to a level of a node corresponding to the node server, and the level of the node may be preset.
In addition, for any one of the one or more groups, all servers in the group share a blockchain. Thus, when the node server is in a group, there is a blockchain corresponding to the group in the node server, and the blockchain is shared by all servers in the group. When the node server is in a plurality of groups, a plurality of blockchains which are in one-to-one correspondence with the plurality of groups exist in the node server, and each blockchain is shared by all the servers in one corresponding group. In other words, for any group, any server (e.g., node server or resource distribution server) included in the group is configured with a blockchain corresponding to the group.
Furthermore, the resource issuing server is a server of a resource issuing authority, and the resource issuing authority may be an authority for issuing resources, such as a financial institution like a commercial bank, a credit company, and the like. Nodes in the supply chain can apply for resources from the resource issuing authority when resource gaps occur.
The operation of the node server determining, from one or more groups in which the node server is located, a target group that is allowed to share the resource indication information may be: when the node server is only in one group, the one group can be directly determined as a target group allowing the resource indication information to be shared; when the node server is in multiple groups, the group identifier sent by the node terminal while sending the resource indication information may be obtained, and the group identified by the group identifier in the multiple groups is determined as a target group allowed to share the resource indication information.
It should be noted that, in the embodiment of the present application, the servers in the blockchain system may be divided into a plurality of groups, and then the resource indication information sent by a certain node terminal is shared in the target group. Therefore, the resource indication information of a certain node is only shared in a small range, and is not shared in the whole world, so that the privacy of the resource indication information is ensured. In addition, since a plurality of groups are configured, different resource indication information can be shared in different groups, thereby improving the flexibility of resource indication information storage.
For example, fig. 8 is a schematic diagram of a plurality of groups according to an embodiment of the present disclosure. As shown in fig. 8, the block chain system includes group 1 and group 2. The group 1 comprises a node server 1, a node server 2 and a resource distribution server, and the node server 1, the node server 2 and the resource distribution server are all configured with a block chain corresponding to the group 1. The group 2 includes a node server 3, a node server 4 and a resource distribution server, and a block chain corresponding to the group 2 is configured in each of the node server 3, the node server 4 and the resource distribution server. At this time, the resource indication information sent by the node terminal corresponding to the node server 1 may be shared within the group 1, that is, the resource indication information may be stored in one block chain corresponding to the group 1 and configured in each server in the group 1. The resource indication information sent by the node terminal corresponding to the node server 2 may be shared within the group 1, that is, the resource indication information may be stored in a block chain corresponding to the group 1 configured in each server in the group 1. The resource indication information sent to the node server 3 by the node terminal corresponding to the node server 3 may be shared within the group 2, that is, the resource indication information may be stored in a block chain corresponding to the group 2 configured in each server in the group 2. The resource indication information sent to the node server 4 by the node terminal corresponding to the node server 4 may be shared within the group 2, that is, the resource indication information may be stored in a block chain corresponding to the group 2 configured in each server in the group 2.
Step 504: the node server adds the block to a block chain corresponding to the target group in the one or more block chains, and synchronizes the block to the block chains configured by other node servers and the resource issuing server included in the target group.
Wherein, the node server synchronizes the block to the block chain configured by the other node servers included in the target group and the resource issuing server, that is, the node server synchronizes the block to the block chain configured by the other node servers included in the target group and the resource issuing server and corresponding to the target group, and the specific operations may be: the node server sends the block to other node servers and the resource issuing server included in the target group, and the other node servers and the resource issuing server can add the block to a self-configured block chain corresponding to the target group. As such, the resource indication information will not be tampered with.
It should be noted that the resource issuing server is configured to determine the resource issuing risk value according to the resource indication information stored in the configured blockchain. In this way, the resource issuing mechanism corresponding to the resource issuing server can determine whether to issue the resource for the node according to the resource issuing risk value of the node in the supply chain.
In addition, the resource distribution risk value represents the probability that the resource cannot be recovered on time after the resource distribution mechanism distributes the resource, that is, the larger the resource distribution risk value is, the larger the probability that the resource cannot be recovered on time after the resource distribution mechanism distributes the resource is, the smaller the resource distribution risk value is, and the smaller the probability that the resource cannot be recovered on time after the resource distribution mechanism distributes the resource is.
In the embodiment of the application, the node server receives the resource indication information sent by the node terminal, and then generates a block according to the resource indication information, where the block is used for storing the resource indication information. Then, the node server determines a target group allowing sharing the resource indication information from one or more groups in which the node server is located. The node server adds the block to a block chain corresponding to the target group in one or more block chains configured by the node server, and then synchronizes the block to the block chains configured by other node servers and the resource distribution server included in the target group. Finally, the resource issuing server can determine the resource issuing risk value according to the resource indication information stored in the configured block chain, so as to issue the resource to the node in the supply chain. Therefore, each node in the supply chain has an opportunity to obtain the resources issued by the resource issuing mechanism, and the flexibility and the accuracy of the resource issuing are improved.
Fig. 9 is a flowchart of a resource distribution method based on a blockchain according to an embodiment of the present disclosure, where the method is applied to a blockchain system, where the blockchain system includes n groups, each group includes a plurality of node servers and resource distribution servers, n is an integer greater than or equal to 2, please refer to fig. 9, where the method may include the following steps:
step 901: and the node server receives the resource indication information sent by the node terminal.
It should be noted that the node server may be any node server in the blockchain system. The node server is a server of any node in a supply chain, the node server is in one or more groups in n groups, one or more block chains are configured in the node server, and the one or more block chains are in one-to-one correspondence with the one or more groups.
In addition, for any one of the n groups, a blockchain corresponding to the group is configured in the plurality of node servers and the resource issuing server included in the group, that is, all the servers included in the group share the blockchain corresponding to the group.
Moreover, the operation of step 901 is the same as the operation of step 501, and is not described again in this embodiment of the present application.
Step 902: the node server generates a block according to the resource indication information, wherein the block is used for storing the resource indication information.
It should be noted that the operation of step 902 is the same as the operation of step 502 described above, and details thereof are not described in this embodiment of the application.
Step 903: the node server determines a target group allowing the resource indication information to be shared from one or more groups in which the node server is located.
It should be noted that the operation in step 903 is the same as the operation in step 503, and this is not described again in this embodiment of the present application.
Step 904: the node server adds the block to a block chain corresponding to the target group in the one or more block chains, and synchronizes the block to the block chains configured by other node servers and the resource issuing server included in the target group.
It should be noted that the operation of step 904 is the same as the operation of step 504, and the description of this embodiment is omitted here.
Step 905: and the resource issuing server receives a risk assessment request which is sent by a terminal of the resource issuing mechanism and carries the node identification.
It should be noted that the risk assessment request is used to request risk assessment for the node identified by the node identifier, that is, to request to acquire the resource issuance risk value of the node.
Step 906: and the resource issuing server determines a resource issuing risk value according to all the resource indication information which is stored in the configured block chain and is associated with the node identifier.
When the resource issuing server acquires all resource indication information associated with the node identifier from the configured block chain, the resource issuing server can search the block in which the node identifier is stored from the configured block chain, acquire the resource indication information from the searched block, and the acquired resource indication information is the resource indication information associated with the node identifier; or, the resource distribution server may obtain the block identifier corresponding to the node identifier, search the block identified by the block identifier from the configured block chain, and obtain the resource indication information from the searched block, where the obtained resource indication information is the resource indication information associated with the node identifier.
Further, before step 906, the resource issuing server may further detect whether the terminal of the resource issuing authority has the query right; when the terminal of the resource issuing authority has the query right, the resource issuing server performs step 906.
The operation of the resource issuing server detecting whether the terminal of the resource issuing mechanism has the query right may be: the resource distribution server sends a reminding message to the node terminal corresponding to the node identifier; when the resource issuing server receives a confirmation message returned by the node terminal according to the reminding message, the resource issuing server determines that the terminal of the resource issuing mechanism has the inquiry authority; and when receiving the negative confirmation message returned by the node terminal according to the reminding message, the resource issuing server determines that the terminal of the resource issuing mechanism does not have the inquiry authority.
It should be noted that the reminding message is used to indicate that the terminal of the resource issuing mechanism is inquiring the resource indication information of the node terminal, and the node terminal receiving the reminding message can determine whether to give the resource issuing mechanism an inquiry authority. The node terminal can display the reminding message when receiving the reminding message; when receiving the confirmation operation of the reminding message, generating a confirmation message and returning the confirmation message to the resource issuing server; and when receiving the denial operation of the reminding message, generating a denial message and returning the denial message to the resource issuing server.
Step 907: and the resource issuing server sends the resource issuing risk value to the terminal of the resource issuing mechanism.
It should be noted that, after receiving the resource issuing risk value, the terminal of the resource issuing mechanism may determine whether to issue the resource for the node identified by the node identifier according to the resource issuing risk value. For example, when the resource issuance risk value is large, the resource may not be issued for the node; when the resource issuance risk value is small, the resource can be issued for the node.
In the embodiment of the application, the node server receives the resource indication information sent by the node terminal, and then generates a block according to the resource indication information, where the block is used for storing the resource indication information. Then, the node server determines a target group allowing sharing the resource indication information from one or more groups in which the node server is located. The node server adds the block to a block chain corresponding to the target group in one or more block chains configured by the node server, and then synchronizes the block to the block chains configured by other node servers and the resource distribution server included in the target group. And finally, when receiving a risk evaluation request carrying a node identifier sent by a terminal of the resource issuing mechanism, the resource issuing server determines a resource issuing risk value according to all resource indication information which is stored in the configured block chain and is associated with the node identifier, and sends the resource issuing risk value to the terminal of the resource issuing mechanism, so that the terminal of the resource issuing mechanism can issue resources to the node in the supply chain. Therefore, each node in the supply chain has an opportunity to obtain the resources issued by the resource issuing mechanism, and the flexibility and the accuracy of the resource issuing are improved.
