Embodiment Construction

[0052] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0053] refer to Figure 1-2 , the embodiment of the present application provides a blockchain data traceability method based on an umbrella cross-chain, including the following steps:

[0054] S1. The designated block chain node obtains the data to be traced; the designated block chain node is a mobile block chain node in the preset designated block chain, and the mobile block chain node refers to a block chain with mobile capabilities node;

[0055] S2. Perform retrospective processing in the main chain storage structure of the designated block chain to determine the des...

Abstract

The invention discloses a blockchain data tracing method based on an umbrella-shaped cross chain. The method comprises the following steps: acquiring to-be-traced data; performing tracing processing in the main chain storage structure to determine a specified main storage block; obtaining a first branch chain storage chain; obtaining a second branch chain storage chain according to the cross corresponding relation; obtaining all branch chain storage blocks, and summarizing the branch chain storage blocks into a branch chain storage block set; calculating the similarity to obtain a plurality of block similarity values; judging whether a preset quantity standard is met or not; if the number meets the preset number standard, extracting half of the branch chain storage blocks; carrying out blockchain node number extraction processing; performing blockchain node number search in the branch chain storage structure to obtain a search result; and according to the search result, generating the organization relation graph, so the security of the stored data is ensured, the data obtained by counterfeiting between the collected data and the stored data is easy to trace, and the relevance data tracing of the blockchain is realized.

Description

technical field [0001] The present application relates to the computer field, in particular to a blockchain data traceability method, system, computer equipment and storage medium based on an umbrella cross-chain. Background technique [0002] The data in the blockchain is traceable. The reason is that the data stored in the blockchain is difficult to tamper with, and the stored data will not change. Therefore, there is data uniqueness and it is easy to perform data traceability processing. However, because of this, when the traditional blockchain traces a piece of data, it can only find a single traceability result (that is, the node that generated the data), so it lacks relevance and cannot trace other data that may have problems. Contents of the invention [0003] This application proposes a blockchain data traceability method based on umbrella cross-chains, including the following steps: [0004] S1. The designated block chain node obtains the data to be traced; the d...
