Abstract: An identity certificate may be issued to a blockchain node. The issuance may include issuing a first identity certificate to a first terminal and receiving a second identity certificate issuance request that is from the first terminal. A second identity certificate may be issued to the first terminal, and a third identity certificate issuance request is received from the second terminal. A third identity certificate is issued to the second terminal, so that the second terminal forwards the third identity certificate to the third terminal.

Abstract: According to an aspect, a method for correcting an invalid script in a web application includes determining an invalid reference in an invalid script. A storage location is determined in a database corresponding to the invalid reference based on a data relationship mapping, wherein the data relationship mapping indicates the correspondence between the reference and a storage location in the database. An up-to-date value at the storage location is queried and he queried up-to-date value is determined to be the correct value of the invalid reference.

Abstract: An array substrate, a display panel, a display device, a method for manufacturing the array substrate and a method for manufacturing the display panel are provided. The array substrate includes a base substrate, and an organic layer and a passivation layer arranged above the base substrate. The base substrate includes a display region and a non-display region surrounding the display region. Each of the organic layer and the passivation layer is arranged in both the display region and the non-display region. A groove is arranged in the organic layer and the passivation layer in the non-display region, the groove penetrates the organic layer and the passivation layer and is of a closed pattern surrounding the display region. The groove is to be filled with a sealing material.

Abstract: Provided are a shift register unit, a gate driver and a display device. The shift register unit comprises: a pull-up control module, a pull-up module, a reset module, and a denoise module for holding a signal output from the first output terminal when the signal has a level higher than a first preset threshold and outputting the held signal from a second output terminal when a signal input from a denoise control signal input terminal has a level higher than a second preset threshold. The signal output from the first output terminal is filtered by using the signal output from the first output terminal and the signal input from the denoise control signal input terminal, and thus burrs in the signal output from the first output terminal are eliminated, that is, noise is eliminated, solving the problem that a defective display picture due to the noise in the output signal.
