Problems solved by technology

[0003] The technical problem to be solved by the present invention is that, in view of the traditional bidding process of the prior art, the public fairness of each link is complicated, and the fairness of information and results depends on the bidding trading platform. Once the platform is attacked, the data may be tampered with, lacking The technical defects of the corresponding information tamper-proof and traceable mechanism provide a blockchain-based bidding processing method and system

Embodiment Construction

[0033] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0034] (1) Bidding process

[0035] refer to figure 1 , assuming that a trusted third party E2 is responsible for the block on the private chain of the entire bidding process, it first selects the publicly known content "ZHAOTOUBIAO" and puts it into the genesis block.

[0036] The bidding entity E1 sends the bidding information M1 to the trusted third party E2 after signing CS(M1).

[0037] The trusted third party E2 stores M1 (for example, in a local location), and the storage address is c:\E2\M1.

[0038] The trusted third party E2 is writing the bidding content data into the BLOCK1 block. At this time, B1 is c:\E2\M1, and B2 is M1, CS(M1).

[0039] The trusted third party E2 generates the block header information A...

Abstract

The invention discloses a block chain-based bidding and tendering processing method and system. The bidding and tendering processing method comprises a bidding processing step, a tendering processingstep, a bid opening processing step, a bid evaluation processing step and a bid winning processing step. The bidding and tendering processing method is adopted for performing bidding and tendering processing. By implementing the block chain-based bidding and tendering processing method and system, the bidding and tendering processes are simple; the openness and fairness of all links are guaranteed; data is difficultly tampered; and a data time sequence is guaranteed and the data can be traced.

Description

technical field [0001] The invention relates to the field of block chain and its application technology, in particular to a bidding processing method and system based on a competitive trust-based third-party private chain for bidding applications. Background technique [0002] Bidding includes bidding, bidding, bid opening, bid evaluation, and bid winning. Designing an open, fair, and just transaction between multi-bidding enterprises and bidding units is an urgent problem that needs to be solved. In the traditional method, it is either based on the whole process control of the closed bidding unit, or based on the bidding and bidding trading platform, and these methods are based on absolute trust. At the same time, in these methods, the bidding process is complicated, the openness and fairness of each link are difficult to fully guarantee, the data may be tampered with, the data time series is difficult to guarantee, and the data is difficult to trace. Contents of the inve...
