Description
Technical Field
The invention relates to the technical field of blockchains, in particular to a bidding performance fusion system based on a blockchain.
Background
In the process of bidding, the following technical problems exist:
(1) Information sharing is opaque: the bid information cannot be shared, and the main manifestation is that: the information release platforms used by the ports lack uniformity, so that the bidding mechanism has larger workload and is extremely easy to deviate when inputting information, and bidding conditions set by bidding units are too harsh, so that certain interference is generated to bidding work. The bidding procedure lacks standardization, and the project unit has the problems of messy additional links, overlong accounting time and low efficiency during engineering calculation and acceptance.
(2) The information is completely unprotected: the construction difference of the electronic bidding in each domestic area is obvious, the implementation standard lacks uniformity, and the bidding business links cannot be practically connected together due to certain difference in construction period, especially the interface compatibility problem cannot be effectively solved, so that the information island problem is serious. The functions cannot be practically connected with the information, so that great negative influence is generated on the sharing of market information resources, all functions in the electronic bidding period are invalid, and the special advantages of the electronic bidding are not fully exerted. Meanwhile, as the information data cannot be effectively shared, the data cannot be communicated in all areas, and the electronic bidding needs to be repeatedly constructed, so that large-scale resources are wasted. Electronic bidding is based on a network environment, and the network has the characteristic of openness, so that a plurality of hidden dangers exist in bidding activities, the confidentiality and the safety of information cannot be effectively guaranteed, and the electronic bidding is a problem which is urgent to be solved currently. The electronic bidding process lacks clear standard and authority mechanisms to judge, so that the normalization of the process is not effectively guaranteed, the necessary fairness and fairness of the construction engineering bidding are lacked, and the difficulty of information acquisition is high.
(3) A real bottleneck occurs in process supervision. The existing construction engineering quality assessment method eliminates the assessment content of quality grades, can evaluate the standard condition by using completion materials only, and is mainly characterized by standardizing various behaviors of bidding units according to social environments at present, so that the quality projects of the current domestic construction market are greatly reduced, and the quality of construction engineering is gradually reduced.
Challenges faced by engineering bidding include difficulty in achieving both efficiency and effectiveness, difficulty in implementing cross-regional sharing, difficulty in implementing cross-stage collaboration, and centralization of the bidding process. In particular, in the current stage, when the conditions of interference caused by human factors occur in the bidding process of the project, some construction units violate the principle to manually control the bidding activities of the project. When the administrative unit is managed, the management is only carried out according to some existing related laws and regulations, and the management is not carried out by taking the actual situation as a fundamental starting point. The effective solution is to perform decentralization during bidding, skip intermediate links such as agency or transaction platform, practically reduce the influence and interference of various subjective factors, practically realize decentralization of bidding procedure, compress transaction flow, practically reduce transaction cost, objectivity and transparency of bidding activity, and actively develop system maintenance by each node, so that the safety of bidding transaction is effectively improved, and the operation risk is greatly reduced.

As shown in fig. 2, as a preferred embodiment, the bid performance fusion mechanism (i.e., bidding procedure) includes: the tenderer initiates the bidding, bidder bids, on-chain bid opening, bid evaluation, scaling, bid evaluation processes disclose query and contract performance.
And in the bidding link of the tenderer, the tenderer issues bidding requirements and uploads the electronic bidding file to the block chain bidding system. In addition, the final manuscript of the mark can be uploaded together, and the final manuscript of the mark can be locked by using a time stamp.
In the bidding link of the bidding party, the bidding party uploads the block chain bidding system after completing the electronic bidding file according to the bidding file compilation, and the final manuscript of the bidding file can be uploaded together and locked by utilizing the timestamp; sensitive information such as a label is further encrypted, so that later tampering and leakage of important information are effectively avoided. In the block chain bidding system, the identity information of bidders is encrypted, illegal operations such as string bidding among bidders are strictly stopped, and the fairness and fairness of bidding environments are ensured.
In the bid evaluation link, the platform firstly checks the validity of all bidding documents, and only bidding documents conforming to bidding rules enter the bid evaluation link. For automatic scoring, evaluation criteria may be written in detail in the smart contracts, and the results automatically generated and stored. For remote evaluation, the identity of the expert is verified by using various modes such as face recognition and the like, and then the evaluation result is uploaded within a certain time, and as the blockchain has anonymity and can realize point-to-point transmission, the expert can be ensured to independently evaluate the label, and the situation that the expert is a specific party station in the process is avoided; and finally, automatically generating the bid evaluation result based on the expert evaluation result by the intelligent combined date, and uploading the bid evaluation result to a blockchain for storage.
The bid evaluation process shows a query link, and an electronic bidding system based on a blockchain technology completely records all bid evaluation information in a bidding process and operation behaviors of parties on a blockchain, and realizes locking based on a time stamp mechanism. After bidding is completed, the system provides an external query interface, all original certificate storage data in the bidding process can be queried through the external query interface, any link occurrence problem can be traced forward and clear to the specific identity of the participant, and the fairness, fairness and transparency of the bidding process are ensured.
And in the contract performance link, the intelligent contract based on the blockchain technology can realize the online instant automatic contract signing of the bidding party and the winning party, reduce the signing period and improve the working efficiency. The block chain platform can track project progress, urge each participant to fulfill the contract content within the specified time period, avoid the default behavior and promote the quality and quantity of the bidding project to finish.
As a preferred embodiment, the bid performance fusion system includes: the system comprises an information acquisition module, an information processing module and an information query module; wherein:
1. the information acquisition module is based on a blockchain information technology and comprises two blockchains, namely a private chain and a alliance chain, wherein a signer, a bidder and an agency are positioned on the private chain with a plurality of companies participating in bidding, and a supervisor and a main body needing service are positioned on the alliance chain with a plurality of companies participating in bidding.
In the conventional bidding forms, data is submitted by the respective subjects. The characteristic of decentralization of the block chain technology is introduced into bidding activities, so that public opening of bidding units and bidding unit information can be improved, different links of bidding data can enable a single node to be generated by a source of the data, the problem of unequal between the bidding units and a main department is solved, and decision rights of centers are continuously weakened. The use of the blockchain technology can not only expand the information acquisition of qualification examination, deposit, bidding documents and the like in bidding activities, but also enable an expert to list all data of bidding units into a tax-paying credit level evaluation range, establish nodes after the data record chain is provided with information by all participating subjects, and the nodes are verified by using a blockchain algorithm and a cryptographic method and cannot be changed. The scheme can improve the comprehensiveness, effectiveness and transparency of the bidding credit data record. The private chain and alliance chain technology is adopted in the process of recording the bidding credit information. When related information resources are obtained, since confidential data of tax payers are only leaked and utilized by others, company safety, social safety and economic safety are necessarily affected. The present embodiment proposes that information collection should use a private chain of information hosting blockchain concepts, while the governing authority should build a federation chain for government agencies when information should be collected from related personnel.
2. Information processing module
First, the information quality is ensured by means of smart contract technology. The premise of credit assessment is basic data of bidding units, but most of information of bidding units has different aspects, and the information is comprehensive and unstable, so that financial risks and reverse selection are easily caused. The intelligent contract layer provides, verifies and fulfills contracts for the data by utilizing the technology, and the data of different nodes can be matched, recombined and verified by utilizing the blockchain technology in the bidding process. In this way, the problem of information inequality of past bidding can be reduced in a certain sense, and the cost of manual reconciliation can be reduced.
Second, the data transport layer of the blockchain ensures that the data in the blockchain can be copied in a special period and cannot be changed. Thus, all nodes can generate public effect for other nodes when being established, all participants can confirm the change condition of data, and special operation records are stored in the nodes, because of open and transparent data processing.
Take a certain bidding unit as an example. The block chain is established based on different nodes generated by company information, deposit, bid amount, contracts, books, schemes and the like in the bidding process, all the added information cannot be modified again, and the information is displayed in a new block for a long time. And all links in the production and management process of the company are made public, and the data is still continuously updated.
3. Information inquiry module
The block chain technology-based communication of data can reduce the cost input by bidding units, namely, the bidding units implement self bidding obligations, obey regulations and participate in other expenses of journey in bidding activities. The use of this technique enables the association of a bid with a network using an information recording layer and an information transport layer. Because this technical support data is continually being upgraded, bidding activity is entered as soon as it occurs. In other words, this technique can ensure that the bid evaluation cost does not change.
The preferred embodiment adopts an encryption algorithm to encrypt the main sensitive data, and has better safety coefficient compared with an electronic bidding platform using rights management. The public key encryption algorithm is utilized to encrypt bidding unit bidding and bid evaluation expert identity data, so that only owners can query the data, and the situation that the key data are not revealed can be fully ensured.
Meanwhile, the unlicensed chain and the alliance chain are reasonably used in the information interaction process. Firstly, aiming at all used unlicensed chains, not only the bidding credit level can be disclosed, but also the punishment and evaluation result suffered by bidding units can be disclosed; secondly, for a alliance chain of government related institutions, information obtained by a master institution from different dimensions and a main body is disclosed in the alliance chain, and a trusted credit sharing mechanism is established. Thus, at the same time, different departments commonly issue incentive penalty systems, thereby deploying deep usage for such data.

Ensuring that different processes are completed according to time limit required by law through intelligent contracts, preventing the process centralization in the current information platform and avoiding the situation of manually modifying data in the background of the information platform; the bid evaluation committee is automatically established in the expert database by using the intelligent contract. Through recording the whole process, the disclosure degree and the credibility of the data materials are ensured, and the problem of non-compliance of the intermediate flow is reduced.
4. Open calibration period
And establishing an intelligent pre-scoring model, wherein the intelligent pre-scoring model can extract subjective and objective scoring factors from the bid clearing table and the bid file to be used as model input, pre-scoring corresponding contents of the subjective and objective parts according to the bid evaluation weight of the scoring factors, and automatically calculating objective scores of all bidders for expert auditing and reference. The method has the advantages that the structured data of the bid-bidding documents, the bid-bidding documents and the bid-bidding-cleaning tables are used as input, part of bid-bidding report contents are automatically generated in an auxiliary mode according to format requirements of bid-bidding reports, a final bid-bidding report is generated after manual auditing and modification, efficiency of the bid-bidding report writer in writing the report is improved, intelligent review and manual review are combined, and review reliability is improved. Meanwhile, the data in the whole bid evaluation process is written into the blockchain, so that the later inquiry is more convenient.

The time stamping technology of the block chain can ensure that bidding units and bidding units meet the time specification and the traceability requirement of supervision, the encryption algorithm can ensure that file information cannot be influenced by utilizing signature and verification signature functions, the bidding confidentiality is improved in the technical aspect, and the condition of human intervention is avoided. The bid evaluation is to integrally judge different aspects of bidders, and mainly comprises price, business, technology and the like. However, how the panelist judges the authenticity of the provided data in the actual process is a main influencing reason related to the fairness of bidding. In the face of the situation of information dispersion faced by current bidding purchasing, each large platform and each large website information are not shared and are data exploration technology. Especially, under the condition that the current electronic bidding becomes a new trend of the bidding industry, bidding units change the aspects of registered funds, detection reports, product performance and the like which are highly valued by panel experts by utilizing an image processing tool so as to realize the behavior of the bidding targets. The advantage of blockchain in the information notarization industry can cope with this situation in time.
3) The alliance chain is used as a block chain technology for setting certain nodes to participate according to corresponding nodes, and the corresponding blocks are controlled by the selected nodes in the stage of achieving common job assignment, so that the technical effect of high-limit pushing bidding process is achieved.
4) The cross-chain technology is used, so that the related data of different block chains can be exchanged and transmitted on a trusted mechanism. In the actual process, related departments or associations can be utilized to construct a bottom layer platform of the system, and data in aspects of company test detection, financial audit and the like can be utilized to achieve the purpose of information sharing by utilizing a alliance chain in the system, so that illegal modification is avoided. The scattered data of the river company utilizes a cross-link technology to compile the bidding document, thereby ensuring the effectiveness and comprehensiveness of the bidding document and avoiding the illegal modification of the company.
5) The BT technology is used for enabling the evaluation of the evaluation expert in the evaluation activity to be traced. Under the condition that personnel of a special institution are allowed to inquire related information and the condition that the evaluation data cannot be changed is ensured, the management can be traced, and the condition that evaluation experts operate evaluation results is reduced.
6) In the traditional bidding process, the contract fulfillment process is mostly supervised by a manual repeated auditing mode, the contract signing and bidding documents can be effectively compared by using an intelligent contract mode, further, automation can be realized by implementing and implementing the contract signing and bidding documents, after the two parties achieve common cognition, the platform can automatically realize the work of payment, signing and receiving and the like, relevant information is recorded in a block chain, and illegal conditions such as subcontracting, subcontracting and the like in the contract fulfillment process are avoided.
