Electronic bidding method, device and equipment based on block chain, and storage medium

Abstract

The invention relates to the technical field of block chains, and discloses an electronic bidding method, device and equipment based on a block chain and a storage medium, which are used for data security in the field of electronic bidding. The method comprises the steps of encrypting bidding data in a bidding document file, converting the bidding data into bidding data packets, cutting the bidding data packets according to a preset storage block size through a data cutting algorithm, and writing the bidding data packets into a block chain; detecting whether a bid opening instruction exists ornot in real time, and when the bid opening instruction is detected, obtaining bid data packet slices from a storage block of the block chain according to the bid opening instruction, and splicing thebid data packet slices to obtain a ciphertext file; and decrypting the ciphertext file to obtain plaintext bidding data, and evaluating bids according to the plaintext bidding data. According to themethod, the bidding data is stored in the block chain, in the bidding process, all participants can supervise the encrypted bidding data at low cost, and it can be effectively avoided that in the bidding process, a bidding platform and a bidder modify the data.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a blockchain-based electronic bidding method, device, equipment and storage medium. Background technique [0002] Bidding is an international practice, a product of the highly developed commodity economy, an organized method of selecting the best deal through the application of technology, economic methods, and the competition mechanism of the market economy. In the traditional bidding mode , Bidding is based on paper documents, and related work is mainly completed offline. With the development of the Internet, the traditional bidding model began to develop into electronic bidding. Electronic bidding realizes the electronic management and operation of the bidding process, which can solve the unfairness brought by many subjective factors to the bidding parties. It is mandatory in implementation, reduces the difficulty of business operations, and avoids business Standa...
