Problems solved by technology

[0005] However, when blockchain technology is applied in the field of urban planning, all the nodes involved in the information processing of the blockchain are usually part-time nodes, and they also need to undertake the original computing work. Therefore, computing resources are often insufficient; moreover, in the field of urban planning The business has relatively obvious business characteristics, and the information exchange of a considerable part of the business is only realized between specific nodes. Therefore, it is not like the complete lack of trust between traditional blockchain nodes. Relatively speaking, there is a certain foundation of trust

Embodiment 1

[0054] The specific steps of the first embodiment are as follows figure 1 shown, including:

[0055] Step 1: Divide the trust relationship between the service initiating node and each service participating node, namely high trust relationship and low trust relationship. The same group of initiating nodes and participating nodes can present different trust relationships in different services. The specific division rules are as follows:

[0056] (1) The internal nodes of the same subnet can be set to a high trust relationship, or the internal nodes belonging to the same functional department can be set to a high trust relationship; this is because the nodes within the same subnet or within a functional department are generally In a trusted environment, the possibility of malicious nodes appearing is very low;

[0057] (2) If they are all internal nodes, but do not belong to the same functional department or the same subnet, when jointly processing a business with a low level o...

Embodiment 2

[0075] The concrete steps of embodiment two are as follows figure 2 shown, including:

[0076] Step 1: Divide the trust relationship between the service initiating node and each service participating node, namely high trust relationship and low trust relationship. The same group of initiating nodes and participating nodes can present different trust relationships in different services. The specific division rules are as follows:

[0077] (1) The internal nodes of the same subnet can be set to a high trust relationship, or the internal nodes belonging to the same functional department can be set to a high trust relationship; this is because the nodes within the same subnet or within a functional department are generally In a trusted environment, the possibility of malicious nodes appearing is very low;

[0078] (2) If they are all internal nodes, but do not belong to the same functional department or the same subnet, when jointly processing a business with a low level of con...

Abstract

The invention provides a city planning domain block chain consensus verification method and system based on aggregation encryption, and the method comprises the steps: dividing a trust relation between an initiating node of a block chain service and each participating node according to a relation between calculation nodes of a city planning domain; two processing flows are divided according to the credibility of the initiating node and the credibility of each participating node. According to the method, high-credibility services among internal nodes are converted into efficient flow processing consensus verification, so that the verification complexity is greatly reduced; for high and low credibility coexisting services, a scheme of setting weights for processing is provided, and the aggregation requirement can be met in advance.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to a blockchain consensus verification method and system in the field of urban planning based on aggregation encryption. Background technique [0002] A blockchain is a chain consisting of one block after another; each block stores certain information and is connected into a chain according to the time sequence of its generation. This chain is kept in all servers, and as long as one server in the entire system can work, the entire blockchain is secure. These servers are called nodes in the blockchain system, and nodes provide storage space and computing power support for the entire blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes, and these nodes are usually in the hands of different subjects, so it is extremely difficult to tamper with the in...
