[0031] Example embodiments will now be described more fully with reference to the accompanying drawings.

Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0034] The specific implementation of the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0035] Figure 1 FIG. 1 is a schematic diagram of a construction project management system in one embodiment of the present application. Figure 1 As shown, the system may include: a blockchain network 11, which includes blockchain nodes 12 of multiple objects related to the construction project.

[0036] The embodiments of the present application do not limit what objects the multiple objects related to the construction project specifically include. For example, the multiple objects may include: construction units, engineering survey units, design units, construction units, supervision units, government units, project management companies, equipment suppliers, material suppliers, etc.

[0037] The embodiments of the present application do not limit which object's blockchain node serves as the master node in the blockchain network 11. For example, the blockchain node of a government unit may serve as the master node, or the blockchain node of a construction unit may serve as the master node, and so on.

[0038] Any blockchain node 12 in the blockchain network 11 can receive project data related to the construction project sent by other devices, and any blockchain node 12 can also report project data on its own. After any blockchain node 12 obtains the project data, it can package the project data into a transaction and send it to the master node. After receiving the transaction, the master node stores the transaction in the transaction pool and queues it to be packaged into a block for consensus.

[0039] In one embodiment, before packaging transactions including project data into blocks, the master node first sends the project data included in the transaction to a supervisory agency for inspection, and receives the inspection results of the project data fed back by the supervisory agency. After that, the master node can package the inspection results into transactions, and then package the transactions including project data and transactions including inspection reports into a block, and then reach a consensus on the block. After the consensus is passed, the block is added to the blockchain and broadcast to the blockchain network 11, so that other blockchain nodes in the blockchain network 11 can update the blockchain.

[0040] The various blockchain nodes 12 in the blockchain network 11 communicate with each other through a network, which can be a wired network or a wireless network.

[0041] Optionally, the wireless network or wired network described above uses standard communication technology and / or protocols. The network is typically the Internet, but may also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a private network or any combination of a virtual private network). In some embodiments, technologies and / or formats including Hyper Text Mark-up Language (HTML), Extensible Markup Language (XML), etc. are used to represent data exchanged over the network. In addition, conventional encryption technologies such as Secure Socket Layer (SSL), Transport Layer Security (TLS), Virtual Private Network (VPN), Internet Protocol Security (IPSec), etc. may be used to encrypt all or some links. In other embodiments, customized and / or dedicated data communication technologies may also be used to replace or supplement the above data communication technologies.

[0042] Blockchain nodes can be various electronic devices, including but not limited to smartphones, tablets, laptops, desktop computers, etc.

[0043] A blockchain node can also be a server. Optionally, the server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), as well as big data and artificial intelligence platforms.

[0044] Those skilled in the art will know that Figure 1 The number of blockchain nodes 12 in the example is only illustrative, and any number of blockchain nodes may be provided according to actual needs. This embodiment of the present application does not limit this.

[0045] Under the above system architecture, an embodiment of the present application provides a construction project management method, which can be executed by any electronic device with computing and processing capabilities. For example, the electronic device is set as the master node in the blockchain network corresponding to the construction project, and the blockchain network includes blockchain nodes of multiple objects related to the construction project.

[0046] Figure 2 A flow chart of a construction project management method in an embodiment of the present application is shown as follows: Figure 2 As shown, the construction project management method provided in the embodiment of the present application includes the following S201 to S204.

[0047] S201, obtaining a first transaction carrying project data of a construction project.

[0048] The embodiments of the present application do not limit what kind of data the project data is. For example, the project data may be a construction plan, or raw material procurement data, or employee salary and payment information, etc.

[0049] The first transaction carrying the project data can be sent by any device to any node in the blockchain network (blockchain node, hereinafter referred to as node). If the node is a master node, the first transaction is directly placed in the transaction pool to queue for processing. After the master node receives the first transaction, it completes the acquisition of the first transaction. If the node is not a master node, the node can send the first transaction to the master node. After the master node receives the first transaction sent by the node, it completes the acquisition of the first transaction and puts the first transaction into the transaction pool to queue for processing.

[0050] It should be noted that any device can be a device outside the blockchain network or a node in the blockchain network.

[0051] If any device is a node in the blockchain network, the first transaction carrying the project data can be directly sent to the master node.

[0052] S202, obtaining a second transaction carrying an inspection report obtained by inspecting the project data, the inspection report including inspection details and inspection conclusions, the inspection details being used to indicate detailed information on the inspection of the project data, and the inspection conclusion being used to indicate whether the project data is abnormal or not.

[0053] The embodiments of the present application do not limit how to check the project data, and it can be determined based on the specific project data.

[0054] In one embodiment, obtaining a second transaction carrying an inspection report obtained by inspecting the project data may include: sending the project data to a supervisory agency for inspection; receiving the inspection report sent by the supervisory agency obtained by inspecting the project data; and creating a transaction including the inspection report to obtain the second transaction.

[0055] Among them, the supervisory agency is an organization that is qualified to inspect project data. The embodiments of the present application do not limit which specific organization the supervisory agency is. For example, the supervisory agency may be an auditing organization.

[0056] After the master node obtains the first transaction, it can obtain the project data from the first transaction, and then send the project data to the supervisory agency for inspection. After the master node receives the inspection report sent by the supervisory agency, it packages the inspection report into a block.

[0057] Checking project data through supervisory supervision can make inspection reports more authoritative, reduce the possibility of falsification of inspection reports, and reduce the complexity of construction project management.

[0058] S203, packaging the first transaction and the second transaction into a block for consensus.

[0059] The embodiments of the present application do not limit how to reach consensus on blocks.

[0060] The consensus process can be as follows: the master node broadcasts the block to the blockchain network. After receiving the block, the nodes in the blockchain network independently verify the block. After the verification is passed, the verification result is fed back to the master node. After the verification fails, the verification result is sent to the master node. The master node counts the number of results that have passed the verification. When the number of results that have passed the verification is not less than the set value of the consensus algorithm used in the blockchain network, the block is considered to have passed the consensus. If the number of results that have passed the verification is less than the set value of the consensus algorithm used in the blockchain network after the master node receives all the results, the block is considered to have failed the consensus.

[0061] In one embodiment, the construction project includes multiple sub-projects, and packaging the first transaction and the second transaction into a block for consensus may include: packaging the first transaction and the second transaction into a block; determining the sub-project to which the project data belongs; selecting the blockchain node of the object corresponding to the sub-project from the blockchain nodes of the multiple objects to obtain multiple sub-project nodes; and using the multiple sub-project nodes as consensus nodes to reach a consensus on the block.

[0062] Construction projects usually include numerous sub-projects, and the objects (units or individuals) involved in different sub-projects may be the same, partially the same, or different.

[0063] For objects involved in the subproject, the corresponding blockchain nodes should participate in the consensus process of the blocks corresponding to the data of the project. For objects not involved in the subproject, the corresponding blockchain nodes may not participate in the consensus process of the blocks corresponding to the data of the project, so as to improve the consensus efficiency, reduce the time used for the consensus process, and save the computing resources of the nodes not participating in the consensus process.

[0064] The embodiment of the present application does not limit how to determine the sub-project to which the project data belongs. In one embodiment, the project data includes an identifier of the sub-project, and the sub-project described in the project data can be determined according to the identifier of the sub-project.

[0065] In another embodiment, the project data includes a sub-project name, and the sub-project to which the project data belongs can be determined based on the sub-project name.

[0066] The embodiments of the present application do not limit how to select the blockchain node of the object corresponding to the sub-project from the blockchain nodes of the multiple objects to obtain multiple sub-project nodes.

[0067] In one embodiment, a third correspondence is stored in the master node, and the third correspondence is a correspondence between a blockchain node and a sub-project. According to the third correspondence, the master node can select a blockchain node of an object corresponding to the sub-project from blockchain nodes corresponding to multiple objects to obtain multiple sub-project nodes.

[0068] When it is necessary to explain, a blockchain node can participate in multiple sub-projects. For example, the blockchain node corresponding to the construction unit can participate in each sub-project.

[0069] Afterwards, the master node will use the multiple sub-project nodes as consensus nodes participating in this round of consensus, and then reach consensus on the block.

[0070] By selecting nodes corresponding to the sub-projects to which different project data belong for consensus, the efficiency of consensus can be improved, the time consumption of the consensus process can be reduced, and resource consumption can be reduced. In addition, by setting the nodes corresponding to the sub-projects to which the project data belongs for consensus, and nodes that do not belong to the sub-project do not participate in the consensus, the accuracy of the consensus can be improved and the influence of malicious nodes can be reduced.

[0071] In one embodiment, the multiple sub-project nodes are used as consensus nodes to reach consensus on the block, including: determining the weight scores of the multiple sub-project nodes in this round of consensus and the consensus threshold of this round; broadcasting the block to the multiple sub-project nodes; accumulating the weight scores of the target sub-project nodes, which are the sub-project nodes among the multiple sub-project nodes that have fed back verification to the main node for the block; in response to the accumulated weight scores of the target sub-project nodes exceeding the consensus threshold of this round, the block consensus is passed.

[0072] The embodiments of the present application do not limit how to assign weights to multiple sub-project nodes, and can be set based on experience. The embodiments of the present application do not limit how to set the consensus threshold for this round, and can be set based on experience. In one embodiment, the consensus threshold for this round is k times the sum of the weights of multiple sub-project nodes, where k is a constant greater than 0 and less than 1.

[0073] By assigning different weights to multiple sub-project nodes, more trusted nodes can have a greater impact in the consensus process, further reducing the impact of malicious nodes on consensus and improving the accuracy of consensus results. In addition, trusted nodes often have faster processing and feedback speeds, which can also improve consensus efficiency.

[0074] S204: If the consensus is passed, the block is added to the blockchain.

[0075] By storing the project data in the construction project as the first transaction on the blockchain, the problem of project data being tampered with or lost can be avoided, and the blocks are arranged in chronological order on the blockchain, and the blocks store data, so that querying project data from the blockchain is simpler, more convenient and faster than flipping through paper or electronic files. By obtaining a second transaction including an inspection report obtained by inspecting the project data, and the inspection report including the inspection conclusion, and packaging the first transaction and the second transaction into one block, anomalies in the project data can be discovered more quickly when querying the project data later.

[0076] Furthermore, since the blocks are arranged in chronological order when they are uploaded to the chain, it is easier to trace the abnormal project data when anomalies are found, so as to better manage the construction projects.

[0077] In one embodiment, after S204, the method further includes: when the inspection conclusion indicates that the project data is abnormal, adding the identifier of the block to the project data abnormality table, so as to query the block.

[0078] The embodiment of the present application does not limit which information of the block the block identifier is. For example, the block identifier may be the block number of the block, or the hash value of the block, or the hash value of the previous block, etc.

[0079] By storing the block number corresponding to the project data in the project data anomaly table when the inspection conclusion of the project data indicates that the project data is abnormal, it is possible to better discover abnormal project data when the project data is subsequently checked, thereby better managing the entire construction project.

[0080] In one embodiment, the construction project includes multiple sub-projects, and the master node stores a first correspondence relationship and a second correspondence relationship, wherein the first correspondence relationship is the correspondence relationship between the block identifier and the sub-project, and the second correspondence relationship is the correspondence relationship between the blockchain node and the sub-project. Figure 3 As shown, the process of querying project data may include S301 to S305, wherein the execution order of S302 and S303 may be interchangeable.

[0081] S301, receiving a query request from any blockchain node among the blockchain nodes of the multiple objects, where the query request includes a query identifier, and the query identifier is an identifier of any block.

[0082] The embodiment of the present application does not limit which information of the block the query identifier is specifically. For example, the query identifier can be the block number of the block, or the hash value of the block, or the hash value of the previous block, etc.

[0083] Any blockchain node can initiate a query request to the master node.

[0084] S302: Determine the sub-project to which any blockchain node belongs based on the second corresponding relationship.

[0085] The embodiment of the present application does not limit how the second corresponding relationship specifically reflects the corresponding relationship between the blockchain node and the sub-project. In one embodiment, the second corresponding relationship includes the corresponding relationship between the identifier of each sub-project and the identifier of the blockchain node belonging to the sub-project.

[0086] like Figure 4As shown, taking the example that the construction project includes 2 sub-projects and the multiple blockchain nodes include 5 blockchain nodes, the blockchain nodes corresponding to sub-project 1 are node 1, node 2 and node 4, and the blockchain nodes corresponding to sub-project 2 are node 1, node 2, node 3 and node 5.

[0087] In one embodiment, the query request includes an identifier of any blockchain node. Based on the identifier, the second corresponding relationship is queried to obtain identifiers of one or more sub-projects, thereby determining the sub-project to which the blockchain node belongs.

[0088] like Figure 4 As shown, the sub-projects to which node 1 belongs are: sub-project 1 and sub-project 2.

[0089] S303: Determine the sub-item corresponding to the query identifier according to the first corresponding relationship.

[0090] The embodiment of the present application does not limit how the first corresponding relationship specifically reflects the corresponding relationship between the block and the sub-item. In one embodiment, the first corresponding relationship includes the corresponding relationship between the identifier of the block and the identifier of the sub-item.

[0091] By searching the first corresponding relationship according to the query identifier, the identifier of the sub-item can be obtained, and then the sub-item can be determined.

[0092] It should be noted that the project data stored in a block belongs to the same sub-project.

[0093] S304, when the sub-project to which any blockchain node belongs includes the sub-project corresponding to the query identifier, the project data stored in the block corresponding to the query identifier is fed back to the any blockchain node.

[0094] S305: When the sub-project to which any blockchain node belongs does not include the sub-project corresponding to the query identifier, feedback that there is no query authority is given to any blockchain node.

[0095] By limiting the querying of project data of sub-projects to nodes belonging to the sub-projects, it can not only ensure that the nodes corresponding to the sub-projects can obtain project data related to themselves, but also reduce the joint tampering and falsification of project data required by different sub-projects before uploading to the blockchain, thereby improving the authenticity and credibility of project data of construction projects and reducing the difficulty of construction project management.

[0096] Based on the same inventive concept, the present application also provides a construction project management device in the following embodiments. Since the principle of solving the problem in the device embodiment is similar to that in the above method embodiment, the implementation of the device embodiment can refer to the implementation of the above method embodiment, and the repeated parts will not be repeated.

[0098] In some embodiments, the second acquisition module 52 is used to send the project data to a supervisory agency for inspection; receive an inspection report sent by the supervisory agency for the project data; and create a transaction including the inspection report to obtain the second transaction.

[0099] In some embodiments, the device further comprises an adding module for adding the identifier of the block to the project data anomaly table when the inspection conclusion indicates that the project data is abnormal, so as to query the block.

[0101] In some embodiments, the consensus module 53 is used to determine the weight scores of the multiple sub-project nodes in this round of consensus and the consensus threshold of this round; broadcast the block to the multiple sub-project nodes; accumulate the weight scores of the target sub-project nodes, which are the sub-project nodes among the multiple sub-project nodes that have fed back verification to the main node for the block; in response to the accumulated weight scores of the target sub-project nodes exceeding the consensus threshold of this round, the block consensus is passed.

[0102] In some embodiments, the construction project includes multiple sub-projects, and the master node stores a first correspondence and a second correspondence, the first correspondence is the correspondence between the block identifier and the sub-project, and the second correspondence is the correspondence between the blockchain node and the sub-project. The device also includes: a query module, used to receive a query request from any blockchain node among the blockchain nodes of the multiple objects, the query request includes a query identifier, and the query identifier is an identifier of any block; according to the second correspondence, determine the sub-project to which the any blockchain node belongs; according to the first correspondence, determine the sub-project corresponding to the query identifier; when the sub-project to which the any blockchain node belongs includes the sub-project corresponding to the query identifier, feedback the project data stored in the block corresponding to the query identifier to the any blockchain node; when the sub-project to which the any blockchain node belongs does not include the sub-project corresponding to the query identifier, feedback to the any blockchain node that there is no query authority.

[0103] The technical solution provided in the embodiment of the present application can avoid the problem of project data being tampered with or lost by storing the project data in the construction project as the first transaction on the blockchain, and the blocks are arranged in chronological order on the blockchain, and the blocks store data, so that querying project data from the blockchain is simpler, more convenient and faster than flipping through paper or electronic files.
