Embodiment 1

[0061] This embodiment provides a grid data integrity detection system based on block chain technology, refer to the attached figure 1 , the system structure includes a hash module, a block module, a blockchain module, and a distributed module;

[0062] Hash module, used to encrypt power grid business data to ensure data integrity;

[0063] The block module is used to store data and ensure the integrity of the data and detect whether the data has been tampered with;

[0064] The blockchain module is used to test the efficiency of the system and the relationship between the mining time and the number of blocks, so as to further optimize the system;

[0065] Distributed modules are used to simulate system data.

[0066] Among them, in the page design process of the hash module, the data is converted into a 256-bit hash through the SHA-256 algorithm. Due to two key reasons, this algorithm is suitable for anti-tampering. One is that the hash is a one-way function , cannot be re...

Embodiment 2

[0090] This embodiment provides a grid data integrity detection method based on block chain technology, refer to the attached figure 1 , including the following steps:

[0091] 1), data generation

[0092] 1.1. The data is generated by four sensors in the form of a combination of numbers and text, and the data will be inserted into the block at the same time. These four nodes are simulated as four sensors to detect the temperature and humidity of different places in the power grid respectively;

[0093] 1.2. Call the data insertion module to generate the data of the block in the sensor, including the humidity, temperature and data source generated by it. By changing the data length and further generating data according to the correlation between the data length and the mining time of the block, the generated data will be will be stored pending further processing;

[0094] 2), data storage

[0095] 2.1. After generating the data, click the "Insert Number of Data" button, the...
