Embodiment Construction

[0049] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0050]As the first aspect of this embodiment, a method for processing bidding information based on blockchain is provided. Such as Figure 5 As shown, the block chain includes bidding nodes 100 (multiple bidding nodes may exist in a block chain network, but for the bidding of a project, there is only one bidding node), bidding nodes 200 (one block There may be multiple bidding nodes 200), regulator nodes 300, and expert nodes 400 in the chain network (there may be multiple expert nodes in a block chain network), wherein, such as figure 1 As shown, the bidding information processing method includes:

[0051] In step S110, the bidding information is encrypted, ...

Abstract

The invention provides a bidding and tendering information processing method and terminal based on a block chain, a bidding and tendering supervision information processing method and terminal, a bidevaluation information processing method and terminal and a bidding and tendering system based on the block chain. The block chain comprises a bidding node, a bidding node, an expert node and a supervision institution node, and the bidding information processing method comprises the following steps: encrypting bidding information, and broadcasting the encrypted bidding information to a block chainnetwork; generating an intelligent contract, and broadcasting the intelligent contract to the blockchain network to extract review expert nodes; and when a bid winning result is received, verifying the bid winning result, if the verification is passed, encrypting the received contract file, and broadcasting the encrypted contract file to the blockchain network. According to the invention, the transparency of bidding and tendering is improved, and heavy loss caused by tampering of bidding and tendering information is avoided.

Description

technical field [0001] The present invention relates to the technical field of block chain and its application, in particular, to a block chain-based bidding information processing method and terminal, a bidding supervision information processing method and terminal, a bidding evaluation information processing method and terminals and a blockchain-based bidding system. Background technique [0002] The bidding system is a management system established for rationally allocating the rights, obligations and responsibilities of the bidding and bidding parties. Strengthening the construction of the bidding system is a requirement of the market economy. [0003] 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, whic...
