Detailed Description
Referring to fig. 1 to 3, referring to fig. 1, a big data processing system of a block chain database according to the present invention includes
At least three node servers 100 for receiving and transmitting first data of other node servers 100 to the blockchain database 101;

For example, the pressure-sensitive screen 310 is provided with 4 pressure-sensitive levels, the 4 pressure-sensitive levels correspond to different pressure-sensitive operation instructions, and the 1 st pressure-sensitive level may be a normal touch pressure-sensitive instruction, that is, a no-press operation, such as a normal click operation or a normal slide operation. The user may click the title information of the first data by using the 1 st pressure level operation, so that the pressure screen 310 jumps to the summary information page; when the pressing force of the 2 nd pressure level is greater than the 1 st pressure level and the user presses the title information of one of the first data of the pressure screen 310 with the 2 nd pressure level, a floating window of the one of the first data is displayed on the pressure screen 310, and the abstract information and the author information of the first data are displayed in the floating window; when the pressing force of the 3 rd pressure level is greater than the 2 nd pressure level and the user presses the title information of one of the first data of the pressure screen 310 with the 3 rd pressure level, a floating window of the one of the first data is displayed on the pressure screen 310, and the abstract information, the author information and the time information of the first data are displayed in the floating window; when the pressing force of the 4 th pressure level is greater than the 3 rd pressure level and the user presses the title information of one of the first data of the pressure screen 310 with the 4 th pressure level, a floating window of the one of the first data is displayed on the pressure screen 310, and summary information, author information, time information, and specific information of the first data are displayed in the floating window.

The more information may be: title information, summary information, author information, time information, and specific information. The device performs floating window display or character conversion display according to the pressing level corresponding to the pressing force of the user. The characters are displayed in a conversion way, and can be understood as follows: the characters in the same window are replaced, for example, the title information is changed into summary information after being clicked.
Preferably, the user terminal 300 is further provided with a voice recognition module capable of recognizing a user voice command, and when the user presses the pressure sensitive screen 310 and does not release his hand, the voice recognition module can control switching of the previous piece of first data or the next piece of first data based on the user voice command.
For example, when a user presses one of the first data in the pressure-sensitive screen 310, the control module 200 may display more information of the first data, such as title information, summary information, author information, time information, and specific information, in a floating window or text-changing manner, and when the user needs to browse more information of the next piece of first data, the control module may directly speak a voice command, such as "switch to previous piece" or "switch to next piece", so that the user can browse more information of the next piece or previous piece of first data without loosing hands or re-pressing.

According to the invention, the gyroscope is matched with the pressure-sensitive screen 310, so that browsing of a plurality of pieces of first data can be realized more conveniently, specifically, the first data can be switched by shaking the mobile phone, and the trouble that a user needs to loose hands to select the next or previous piece of first data and then click the first data is avoided.
Preferably, the pressure-sensitive screen 310 is provided with at least four pressure-sensitive levels, a pressure difference value between each pressure-sensitive level is a pressure threshold a, and the control module 200 outputs the pressure threshold a according to the screen size b, the user gender coefficient c, and the shortest distance d between the touch point and the screen frame according to the following formula:
