Embodiment 1

[0048] Such as figure 1 As shown, a location-based blockchain consensus method includes the following steps:

[0049] S110. Receive a request for adding an application node, where the application node is a full-function node for receiving satellite positioning raw data;

[0050] S120. The verification node verifies the identity of the application node to verify whether the identity of the application node already exists in the blockchain network. If it exists, accept the application node and establish a connection. The verification node is At a node adjacent to the application node;

[0051] S130. If there is no node identification, the application node is required to send the satellite positioning raw data, and the authenticity and validity of the application node are verified by a high-precision positioning solution method. If the verification is passed, the preliminary endorsement is made. the above application node;

[0052] S140. The verification node sends the origina...

Embodiment 2

[0063] Such as figure 2 As shown, a location-based block chain consensus method, wherein, after the verification and full endorsement of multiple adjacent nodes, the application node completes the joining of the block chain network, including the following steps:

[0064] S210. The requesting node sends a satellite positioning raw data request including private key signature timestamp and identification to multiple adjacent nodes;

[0065] S220. The multiple adjacent nodes return the corresponding satellite positioning original data signed by the private key, and at the same time, the requesting node sends an endorsement request to the multiple adjacent nodes, and the multiple adjacent nodes give the endorsement results through the positioning solution method , when more than half of the adjacent nodes give the endorsement result, record the requesting node to the blockchain network.

[0066] In Embodiment 2, the block chain network is composed of multiple nodes, and the loc...

Embodiment 3

[0068] Such as image 3 As shown, a location-based blockchain consensus device includes:

[0069] Receiving module 10: for receiving a request for adding an application node, the application node is a full-featured node for receiving satellite positioning raw data;

[0070] Verification module 20: used for the verification node to verify the identity of the application node, to verify whether the identity of the application node already exists in the blockchain network, and if it exists, accept the application node and establish a connection, so The verification node is an adjacent node at the application node;

[0071] Preliminary endorsement module 30: used for new application node identification verification, requiring the application node to send the satellite positioning original data, and verifying the authenticity and validity of the application node through a high-precision positioning solution method, if the verification is passed, The application node mentioned in ...

Abstract

The invention discloses a position-based block chain consensus method, system and device. A wide-area, ubiquitous and robust location service and identity authentication service are provided by extracting location information through numerous equal participating nodes and performing cross validation, and contributions of block chain participating nodes comprise verifiable basic positioning information, identity authentication of other nodes, information authentication and positioning information use metering. The block chain system is low in calculation amount demand, and full-function nodes can be operated in an embedded system. According to the invention, a wide-area, high-precision and low-cost positioning suit infrastructure can be provided.

Description

technical field [0001] The present invention relates to the technical field of block chain applications, in particular to a location-based block chain consensus method, system and device. Background technique [0002] Positioning service is a basic service, and the common ones are global satellite GNSS system; mobile network-based positioning system; Lora-based metropolitan area positioning system; Bluetooth-based positioning system; ultra-wideband-based positioning system, etc. Among them, only GNSS can provide relatively complete outdoor coverage capabilities, while other positioning systems can only provide coverage capabilities in a certain area. [0003] Generally, the positioning accuracy of a single GNSS client is not high. When dynamic decimeter and centimeter level accuracy is required, differential and RTK technologies are required, and reference stations or CORS services are required to support high-precision positioning mobile stations to complete high-precision ...
