Embodiment Construction

[0071] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0072] The embodiment of the present invention proposes a block chain data encryption sharing method, such as figure 1 As shown, the method includes:

[0073]S1. When a data change occurs in a node in the blockchain, the changed data is encrypted, and a data change docking request is sent to a shared node that has a shared data link relationship with the node;

[0074] S2. Setting a preset data update docking request receiving time period and a preset data update time period of the shared node;

[0075] S3. The shared node performs security verification on all nodes that send data change docking requests within the preset data update docking request receiving time ...

Abstract

The present invention proposes a block chain data encryption sharing method and system, the method includes: when a node in the block chain changes data, encrypt the changed data, and link the shared data to the node The shared node of the relationship sends a data change docking request; sets the preset data update docking request receiving time period and the preset data update time period of the shared node; the shared node updates the preset data update docking request receiving time within the preset data update time period All nodes that send data change docking requests in the segment perform security verification, and complete data updates according to the security verification results; adaptively adjust the preset data update docking request receiving time period and the preset data update time period; shared nodes follow the self-adaptive The adjusted preset data update docking request receiving time period and the preset data update time period perform data update processing. The system includes modules corresponding to the method steps.

Description

technical field [0001] The invention proposes a block chain data encryption sharing method and system, belonging to the field of block chain technology. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. [0003] Blockchain is an important concept of Bitcoin. It is essentially a database of the district center. Blockchain can be considered as a shared database, and each node of a registered user can store a public key in the shared database. , Non-tamperable data, so as to achieve decentralization and non-tamperable functions. It is of great significance to the fields of finance, insurance, logistics, warehousing, banking, currency, etc. However, if the shared database is entered into illegal data or viruses by a registered user of a certain node, it will threaten the security of the entire blockchain, and now In the data s...
