Embodiment 1

[0038] This embodiment discloses a blockchain-based bidding data processing system, such as figure 1 As shown, it includes a block chain network, the block chain network includes an application layer, a transaction layer, and an underlying platform, and the application layer, the transaction layer, and the underlying platform are sequentially arranged from top to bottom;

[0039] Compared with the traditional bidding operation mode, the block connection + bidding trading platform process is safer, more efficient and more reliable. The P2P bid evaluation by the judges does not interfere with each other, which can ensure the objectivity of the bid evaluation to the greatest extent; once the bid winning information is confirmed and meets the stipulated publicity period, the bid winning notice will be sent to the winning bidder immediately, strictly abide by the time node and not procrastinate;

[0040] The application layer is used to establish a visual management of transparent ...

Embodiment 2

[0065] This embodiment discloses a blockchain-based bidding data processing method. This embodiment is implemented based on the blockchain-based bidding data processing system provided in Embodiment 1. The processing method is as follows:

[0066] The bidder submits the electronic version of the prepared bidding documents through the blockchain platform in accordance with the requirements of the bidding documents, uploads the hash value of the final draft of the bidding document to the blockchain for storage, and locks it with a time stamp;

[0067] The bidder submits the electronic version of the prepared bidding documents through the blockchain platform in accordance with the requirements of the bidding documents, uploads the hash value of the final draft of the bidding document to the blockchain for storage, and locks it with a time stamp. The blockchain platform is used to ensure Sensitive information in bidding documents cannot be changed after submission;

Abstract

The invention discloses a bidding and tendering data processing system and method based on a block chain. An application layer, a transaction layer and an underlying platform are sequentially arranged from top to bottom; the application layer is used for establishing transparent bid evaluation, anti-counterfeiting verification, establishment of visual management of public trust and data storage, and storage of any processing information in a bid inviting process data processing process; the transaction layer is used for independently evaluating bids by expert judges after a bidder submits a bidding file in the system, and automatically triggering a contract and automatically executing the contract based on an intelligent contract; the bottom layer platform is used for establishing a network protocol, a security mechanism, a smart contract and consensus management in a block chain network; the system has the beneficial effects that the block chain is combined with bidding and tendering services, data disclosure and transparency are realized, and the security performance of data information is improved; the characteristics of decentralization, high transparency, non-tampering, safety, credibility and the like of bidding and tendering service processing data are realized.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a blockchain-based bidding data processing system and method. Background technique [0002] Bidding refers to the procurement behavior of goods, projects and services. The tenderee attracts many bidders to compete on an equal basis according to the same conditions through the procurement requirements announced in advance, and organizes technical, economic and legal experts in accordance with the prescribed procedures. The conduct process of comprehensive evaluation of bidders and selection of the winning bidder for the selected project. Its essence is to obtain the best goods, projects and services at a lower price. However, in the traditional bidding technology, the data of the whole bidding process will not be disclosed, so the bidding process will not be open and transparent, and the data security performance is not high, and the traceability is poor. [0003...
