Background

The housing construction industry plays an important role in promoting social welfare and prosperity. However, the construction industry is currently faced with a number of challenges, including construction costs rising, delays, which can lead to cost outages, legal disputes, even construction safety risks, etc. One of the root causes of these problems is the lack of efficient data management and data sharing and interaction by the industry.

Traditionally, the building construction industry has relied on manual and decentralized data management procedures, which can lead to data islanding, data inconsistencies, and data errors. For example, parties involved in a building project, such as building units, construction units, first parties, and proctoring units, may use different software systems and formats to store and exchange data, thereby resulting in difficulties in accessing, integrating, and verifying the data. Furthermore, due to lack of security measures and centralized control, data may be susceptible to errors, tampering, and unauthorized access. Therefore, the industry is inefficient, has poor interoperability and has low trust between parties.

Blockchains are a distributed ledger technique that allows multiple parties to record and verify transactions in a secure, transparent, and decentralized manner. A blockchain consists of a series of blocks, where each block contains a transaction list and the cryptographic hashes of the last block. The transaction is validated by a consensus mechanism and added to the blockchain, which involves multiple nodes in the network agree on the validity of the transaction. Once added to the chain, the transactions become immutable and transparent because they are stored in multiple copies of the ledger and can be verified over the network.

Blockchain technology will potentially change various industries and departments in the future by enabling secure and efficient data exchange and verification. Blockchain technology has been applied in various areas of finance, supply chain, healthcare, and government to address challenges and opportunities related to trust, security, and interoperability.

On the premise of fully considering the principles of advancement, practicality, normalization, expandability, safety, confidentiality, sharing and inheritance, a data hub system design framework established on the basis of a blockchain is shown in fig. 1, and comprises eight parts, namely a hub management module, a node management module, a public storage space management module, a channel management module, a contract center module, a user group module, a user information editing module and a management voting module; the hub management module is used for acquiring the operation state of the hub in the data hub system and making corresponding adjustment and maintenance. The node treatment module is used for obtaining the current running condition of the block chain node and controlling the expansion, the change and the elimination of the node. The public storage space management module is used for acquiring the use and operation conditions of the public storage space. The channel management module is used for managing and controlling the channels in the current data hub ecosystem and managing and controlling the contract version of channel deployment and the associated condition of the channel user application system. The contract center module is used for issuing, uploading, version updating and logging-off operation of the contract file. The user group module is used for obtaining the user organization structure relationship and the user detailed information in the current data hub system. The user information editing module is used for editing information of a user, registering an application system, associating the application system to a certain hub and registering certificates for the application system. The treatment voting module provides information notification for users and takes part in the voting working area, and when other modules initiate the influence on the hubs, nodes, channels, contracts, public storage space and users in the data hub system, multiparty voting is carried out through the module. The functional description of each module is as follows:

The hub management module is used for displaying the relation among the nodes of the data hub system, the hub and the application system. And when the hub is newly added, logged off, information is changed or the associated node is associated with an application system, synchronously updating the information to the module. The hub management module is also used for displaying the transaction status of all the hubs in real time, displaying the business storage information in real time, and needing to contain time, passing through the hub, initiating the system and transaction id. Counting the number of hubs, nodes, associated systems and contracts, and counting the number of transactions initiated daily.

The node treatment module is used for displaying the block chain node information in the data hub system and comprises node names, construction units, construction time and node description. The nodes should be able to update synchronously after they are newly added, logged off or information changed. The node management module can initiate the services of newly-built nodes, changing node information, disabling nodes and the like, and the services are executed after the common voting.

The public storage space management module is used for statistically displaying the use condition of the public storage space and the information of each storage node in the data hub system. The total amount of storage space, the usage amount and the allowance need to be contained, and the construction unit, the construction time, the node description, the node storage space amount, the storage space usage amount and the allowance of the storage nodes are stored. After the public storage space is expanded and the storage nodes are newly added, the public storage space is synchronously updated to the module.

The channel management module is used for managing and displaying channel conditions in the data hub system. Including the channel list and channel details. The channel list display includes channel name, last update time, channel description, block height, number of transactions, number of channel associated systems, and number of contracts deployed. In addition to the above information contained in the channel details, the channel associated system and deployed contracts should be displayable and contract deployment and update initiated.

The contract center module is used for managing and publishing intelligent contract files in the data hub system. Including a list of contracts and contract details. The contract list contains the name, description, version, status, language used, uploading user, and the latest update time of the contract. Contract source code should be previewable and downloadable. The contract state includes published, voted, draft, and revoked. The three states of released, voted-in and cancelled are common to all users, and the draft is displayed for each user according to the draft submitted by the user. The draft contract file is considered as a draft, cannot be deployed, and is not visible to non-uploading accounts. Details of the contract draft may be entered for publishing the draft. After release, users with voting authority need to vote, and the voting agrees to enter the released state in a half way. The published state contract file may be invoked for deployment by the channel administration module. The issued contract file can be withdrawn, meanwhile, the contract with the same name cannot be in the issued state, and the original contract file is required to be withdrawn before a new contract is issued. And after the contract file is revoked, the contract file enters a revoked state, and all contracts with the same name and different versions are combined into one.

The user group module is used for displaying user information and organization relations among users, and the information comes from each user information editing module, can only be used for viewing and cannot be changed. The organization relation tree is constructed according to the organization relation among the users, and the users are classified, so that the association and the affiliated relation among the users are represented.

The user information editing module is used for displaying and managing account information of the user, wherein the unit name, the mailbox, the telephone, the address and the introduction can be filled in at will. The unit property, industry and organization relation are set as options, wherein the organization relation options are read from the member module. The user information editing module can also initiate application of certificates, and the certificates under application need to be marked. Certificate aliases, certificate serial numbers, and expiration dates, the certificates may be revoked. Modification of the password should be supported; the registration of the application system can be performed, the name of the registration system needs to be noted, the serial number is automatically generated, and the serial number can be related to the hub and the binding certificate. The method supports the cancellation of the registration system, simultaneously removes the relation between the hub, the channel and the certificate, introduces the distributed certificate to apply for the original certificate, and innovates the verification mode. The method comprises the following steps:

The distributed credentials can realize the backup of the credentials based on the credential archive center and the identity authentication of the user based on the user authentication center, the backup archive and the user identity are managed by different modules in a normal state, and the credentials can be associated when the credential backup is invoked. Meanwhile, the distributed data storage is met, data security protection of different types and different levels is provided, and the key data security of a user is fully protected; and meets the butt joint with the credential service, receives the credential backup information and the backup archive call request initiated by the credential APP and responds.

As shown in fig. 2, the credential archive center mainly includes:

(1) Establishing a document file: when a new certificate is generated in any mode, a corresponding certificate file is established, and the user information is managed by the certificates in the file when the certificates are stored and belong to different centers. And carrying out association with the user according to the association relation only when the user calls.

(2) Backup archive update: when the corresponding certificate of the backup file is changed due to the service, the change information is acquired from the certificate service to synchronously update the file, so that the consistency of the backup file and the data stored in the certificate APP is ensured.

(3) And (3) calling a backup archive: when the credential APP needs to regenerate the credential due to equipment replacement or data loss, user identity information is sent, and the archive backup archive is called through the association relation by the information.

As shown in fig. 3, the user authentication center mainly includes:

(1) User registration: when the user applies the distributed certificate for the first time, an identity certificate is generated through identity recognition. After the identity credentials are generated, the synchronization completes user registration at the user authentication center.

(2) Device registration and modification: after the user is registered, the binding equipment is registered as the storage equipment of the user credentials according to the equipment codes of the user association authentication. After the user changes the device to re-associate, the registered device is changed to a new device.

(3) Association relation: and establishing an association relation between the user, the credentials and the equipment, and determining which files to call according to the association relation when the credentials are called for backing up files after the equipment is replaced by the user.

The treatment voting module is used for providing information notification for users and participating in a voting working area, and when other modules initiate the influence on the hubs, nodes, channels, contracts, public storage space and users in the data hub system, multiparty voting is carried out through the module. The treatment voting module informs the current user of things to be handled and information to be checked. For users with voting rights, when related voting of channels, contracts and new member applications is required, a notification of voting is issued, and the users need to vote. The contract file issued by the current user receives the notification after voting, and the notification is sent after the user applies for the certificate.

The design architecture for the data intercommunication software platform is shown in fig. 4, and comprises an infrastructure layer, a blockchain supporting layer, a system service layer and a business application layer, wherein the blockchain technical platform is used as a core, and the original data hub system is used as a basis, and the interface provided by an intelligent contract, a consensus mechanism and the like is used for realizing the butt joint with the upper data hub system service to provide the services of resource management, resource submission, data monitoring, authority authentication and the like.

In the present invention, the infrastructure layer mainly refers to a large distributed blockchain infrastructure which is completely available for application of building enterprises, and comprises the design of the building of a blockchain node network, the storage capacity of a database, the calculation power resources of a server, the resource scheduling capacity of a distributed system, and the like.

The blockchain support layer is mainly used for designing a blockchain operation mechanism based on an infrastructure layer, and comprises the design of a consensus algorithm, the design of an intelligent contract, the introduction of a security system, the design of monitoring logic, and the provision of unified authentication, unified authority and the like for users. The method comprises the following steps:

1. professional service alliance chain:

Blockchains are currently divided into three types: public chain, private chain, alliance chain. Obviously, as a data sharing and exchanging platform for building enterprise users, the data sharing and exchanging platform cannot be realized in a private chain mode, and also a common public service and a block chain (base) platform are not provided, so that the data sharing and exchanging platform cannot be made into a public chain. Thus, the most suitable form is a federated chain. The platform provides all-round services for all parties in the construction process in a alliance chain mode is a necessary choice. After the user requests login authentication and passes identity authentication and authorization, the user can use the service provided by the platform. The authentication mode adopts an asymmetric key mode for authentication.

2. Consensus mechanism:

The platform operates under the spirit of ensuring the health of clients under national laws and regulations. How to realize consensus among various units or entities or clients, achieving reciprocity and reciprocity, benefit sharing and cooperation win-win, which requires coordination of various subjects and compliance with game rules in a system platform. On the basis, the operational execution rules are realized on a system platform by utilizing the characteristics of the blockchain, and are automatically realized on the system.

3. Data storage

The method adopts a mode of combining on-chain and off-chain, hash verification of data and on-chain transaction of small-capacity data are carried out through a blockchain, and a large amount of data are transmitted and stored through a platform or other transmission modes.

4. Intelligent contract

The platform is developed based on a Fabric framework, and main tasks involved in development include development of intelligent contracts, development of clients, selection of consensus mechanisms and the like. Smart contracts are means of applying contacts and manipulating blockchains, which are languages in which developers communicate with blockchains. The smart contracts can define more complex logic during writing and reading, thereby ensuring that the writing of data is constrained by the non-tamperable smart contracts. The block chain platform consensus process is divided into two parts in total, namely a transaction endorsement process and global ordering of transactions. Global ordering is the part of the operation of the consensus mechanism, and because of the distributed system, no global unification is available all the time, so orderer is required to perform global ordering on transactions sent by different nodes. The consensus mechanism can ensure that the whole block chain system can still achieve consensus under the condition that the network is not communicated to cause node failure or malicious nodes exist, and the consistency of data is met. The contract design can adopt files such as a programming business model, transaction scripts, access control and the like to design and limit the contract logic under different scenes. To satisfy the multi-party interests, promote further development of federation chains and pricing of different data, various solutions are provided in designing contracts, allowing different users to choose a transaction style appropriate to the current environment. Various processes and decisions of the building construction industry can be automated and simplified through intelligent contracts. For example, the bid process may be used to automate the SCE's bidding process by evaluating the bid and selecting the bid according to predefined criteria. At the same time, intelligent contracts can also improve transparency and accountability of flows and decisions, as the terms and execution of the contract can be viewed and verified by parties and networks. This may reduce the risk of errors and disputes and increase trust and collaboration between the parties.

The system service layer mainly provides service interfaces for an upper business application layer, and comprises a resource management interface, a permission authentication interface, a certificate management interface, a contract management interface, a payment settlement interface and the like.

Each user participating in the chain requires its own identity management, including authentication and role management. When a user registers, the dedicated encryption mechanism generates an own key pair for each user. The CA can issue different certificates to the user and the organization according to different scenes, so that the identity authentication requirements of the user and the organization in various scenes are met. The multi-channel mechanism can associate the peer node with the orderer node to form a plurality of communication links with confidentiality, thereby facilitating the identity authentication of users in the channel. The multi-chain then enables the participant to be isolated or authorized from the data to a much greater extent.

Based on the business requirements, developing intelligent contracts aiming at confidential and non-confidential data, and completing basic operation flow planning for the transaction between the client and the platform. The communication process authenticates the identities of both sides, adopts a mode of mixing a symmetric key and an asymmetric key, gives consideration to the transmission speed and the safety of data, and ensures the credibility, traceability, effectiveness and privacy safety of transactions. The blockchain technique ensures that each participant can independently verify the data transaction process, thereby ensuring that the whole data transaction system is realized:

1. the identities of all the transaction parties are true and reliable, so that transaction fraud is avoided;

2. transaction data cannot be tampered and cannot be counterfeited;

3. The transaction process is highly automated, so that the probability of human error is reduced, the labor cost is saved, and the flow efficiency is improved;

4. each authorization link is ensured to be effectively executed, so that the data security is ensured;

5. user privacy is protected by contract-specified data processing and encryption.

The business application layer is the uppermost application layer, and relies on the platform of the whole blockchain to combine the advantages of business logic of the application and the blockchain platform. The platform utilizes a decentralised application to provide user-friendly interfaces and functions for parties involved in the construction process. The application layer enables parties to access and interact with the data and services of the platform through a web-based portal or mobile application. The application layer provides various functions and services such as data visualization, data analysis, communication and collaboration, and workflow management. For example, the application layer may implement automated engineering progress tracking and payment flows by tracking task completion and accepting engineering money according to progress. The application layer may also implement a planning review and approval process for automated regulatory authorities, allowing the authorities to review and comment on plans and reports in real-time and issue approvals based on feedback.

Examples

During the planning and construction phase of an item, parties need to exchange and manage a large amount of data, including planning, specification, schedule, budget, reporting, and approval. However, data is often stored in different software systems and formats and is prone to errors, inconsistencies, and delays. For example:

1. the architects and constructors use different software systems for design and analysis, which can lead to difficulties in data exchange and integration.

2. The contractors and subcontractors use different software systems for scheduling and progress tracking, which may cause discrepancies and delays in scheduling updates.

3. Regulatory bodies use different software systems to review and approve plans and reports, which can lead to lengthy review periods and expensive rework.

To address the data management challenges, parties decide to implement the trusted interworking software platform of the present invention in the project. The platform is deployed on a private blockchain and operated by the complexes of the parties. The federation is responsible for building and maintaining blockchain networks, as well as defining and enforcing the rules and policies of the platform.

The platform is integrated with the parties' existing software systems through APIs or the like, allowing them to store and retrieve data in a standard format on the blockchain. The platform also provides a web-based portal that allows parties to access and interact with data in a user-friendly interface. The platform also utilizes smart contracts and decentralizing applications to automate and simplify the various processes and decisions in the project.

The implementation of the data hub system in housing construction projects brings practical benefits, specifically:

Improving data management: the platform provides a single, true source of data, eliminating the need for manual data entry and verification. The data is stored in a standard format, which facilitates integration and interoperability of the data. The data is also transparent and immutable, which ensures the accuracy and integrity of the data.

Error reduction and efficiency improvement: the process and decision automation is realized through intelligent contracts and decentralizing application programs, and errors and delay risks caused by manual errors and decisions are reduced.

The cost is reduced: the introduction of data hub systems can automate and simplify the process and decisions and reduce errors and rework to reduce costs. The platform may also reduce the need for physical labor and intermediaries, which may reduce transaction costs.

Efficiency and productivity are improved: the data hub system can improve the efficiency and productivity of the parties participating in the construction process by providing more efficient and reliable data exchange and use modes. Real-time monitoring and coordination can be realized, so that the mobility and coordination of work are improved.

Adding trust and collaboration: the data hub architecture can provide a secure and transparent way to store and exchange data, as well as increase trust and collaboration among parties by enabling real-time communications and feedback. The data hub architecture may also provide tamper-resistant logging of events and protocols, facilitating resolution of disputes and conflicts.

The above-described embodiments are intended to illustrate the present invention, not to limit it, and any modifications and variations made thereto are within the spirit of the invention and the scope of the appended claims.
