BIDDING INFORMATION PROCESSING METHOD BASED ON BLOCK CHAIN, SYSTEM, APPARATUS, AND MEDIUM
Document Type and Number:
Japanese Patent JP2022033002
Kind Code:
A

To provide a bidding information processing method, a system therefor, an apparatus therefor, and a recording medium therefor which, by using a block chain network having a smart agreement, forms separation among a bid tenderer, a bidder, a bidding evaluation expert, and a successful bidder determination committee and effectively prevent a cunning phenomenon from occurring.SOLUTION: A bidding information processing method according to the present invention has a step of acquiring a bidding certificate from a first node, a step of transmitting the bidding certificate to a second node to acquire a BIM bidding document from the second node, a step of transmitting the BIM bidding document to a third node to acquire a review result for the BIM bidding document from the third node, and a step of transmitting the review result to the fourth node to acquire a closing bid result from the fourth node. The bidding information, bid tendering information, the review result and the closing bid result are broadcasted to a consortium chain.SELECTED DRAWING: Figure 1
