Description
Technical Field
The invention belongs to the technical field of computers, and particularly relates to a bidding method, a bidding system, bidding equipment and a storage medium based on a block chain.
Background
The bidding is a comprehensive economic responsibility system form for promoting competition in the field of basic construction, along with the rapid development of the Internet, the bidding activity is gradually electronized, the electronic bidding enables the communication process to be more convenient, and the efficiency of the whole bidding work is obviously improved on the premise of reducing the cost. The bidding process of the existing electronic bidding platform mainly comprises the following steps: the tenderer needs to register and log in the electronic tendering and bidding platform to input basic information for auditing. And after obtaining the bidding qualification, the tenderer registers the bidding project, can begin to compile bidding documents, can upload the bidding documents after completing the compilation, and releases the bidding information on the bidding platform. The same bidders need to register and log in the bidding platform to submit enterprise information for auditing in the bidding process; after obtaining the bidding qualification, the bidder can search the interested items by checking the bidding announcement in the bidding platform and download the bidding document, and the bidder can generate the bidding document on line and realize on-line one-key remote bidding. After the bid is opened, the bid inviting unit invites the bid evaluation experts to evaluate the bid on the project. The expert can develop bid evaluation work after logging in the platform, the project can be scored according to the grading detailed rules appointed by the bid inviting party in the bid evaluation process, whether the bid inviting party has bad bidding behaviors including false bidding and the like or not in the bidding link is evaluated, after all bid evaluators complete the work of the expert, bid evaluation results can be uniformly submitted to bidding units for accurate calculation according to the grading detailed rules and the bidding information of suppliers, one or more bid winning units are selected from the first few bidding units in the ranking, and finally bid winning announcements are issued.
However, the current electronic bidding method and system have the following problems: firstly, bidding document information is easy to leak, which is mainly embodied in two aspects, firstly, a platform side can simply obtain a plaintext of a bidding document, the leakage of bidding information can be caused by artificial or technical reasons of the platform, such as internal personnel leakage or hacking, and the like, and then actions such as information transaction and the like can be caused, so that part of bidders obtain bidding opponent information, and unfairness of bidding is caused; on the other hand, the tenderer can obtain bidding information of each bidder, bidding information is leaked in the working processes of bidding transfer printing and the like, and information transaction and other behaviors can be caused subsequently, so that part of bidders obtain bidding opponent information, and unfairness of tendering is caused. And secondly, the qualification of some bidders may be false, which may cause the bidding of bad bidders to enter the network, and the qualification difficulty and workload of the bidders are verified by experts in the bid evaluation process.
