Problems solved by technology

[0002] In the existing blockchain system based on the P2P (Peer to Peer) peer-to-peer network, the credibility of the business system itself is not considered. It is based on the premise that the participating nodes are completely untrustworthy and completely relies on the blockchain to provide a trust mechanism. The block chain system adopts a fixed consensus scheme for all businesses, and the data must be completely transparent to all nodes in the system. On the one hand, this solidified scheme requires high data transmission and storage costs, and on the other hand, it violates the privacy of business data

Embodiment Construction

[0025] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention. It should be noted that in the following description, when detailed descriptions of known functions and designs may dilute the main content of the present invention, these descriptions will be omitted here.

[0026] Due to the fixed consensus method in the existing blockchain technology, data must be shared transparently at each node, causing the entire blockchain network to have great transmission and storage pressure; moreover, in real business, data is a business party The core value of , in addition to the content that must be shared and the peer-to-peer business parties that must be shared with it, the business side will strongly require data privacy. The existing mandatory transparent consensus will lead to the failure of business collaboration relying on the blockchain. ...

Abstract

The invention discloses a method for dynamically adjusting a block-chain consensus based on a business trust degree. In a block chain system, nodes are divided into authentication nodes and consensus nodes; data are only transparently shared among the authentication nodes; and for weakly trusted or completely untrustworthy businesses, node sets for authentication and consensus participation are designated, so that the trust of the cooperation side can be obtained and privacy of the business data can be protected. Compared with the prior art, the method has the following beneficial effects: in the block chain system, the consensus is adjusted dynamically by combining the business trust, so that the block chain system can adapt to application scenes with different business trust; the whole-network popularization requirement of data transmission and storage can be reduced; the system can be trusted; cost minimization can be realized; and thus the block chain technology can be widely applied.

Description

technical field [0001] The invention belongs to the field of information technology, and more specifically relates to a method for dynamically adjusting consensus based on business trust in a block chain system to meet the dynamic needs of data transparent sharing and minimize costs. Background technique [0002] In the existing blockchain system based on the P2P (Peer to Peer) peer-to-peer network, the credibility of the business system itself is not considered. It is based on the premise that the participating nodes are completely untrustworthy and completely relies on the blockchain to provide a trust mechanism. The block chain system adopts a fixed consensus scheme for all businesses, and the data must be completely transparent to all nodes in the system. On the one hand, this solidified scheme requires high data transmission and storage costs, and on the other hand, it violates the privacy of business data . [0003] In practical applications, business systems have a c...
