Example Embodiment

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0036] Based on the fact that the authenticity of the abnormal credential data recorded by the third-party organization is relatively low, which in turn leads to the problem that it is impossible to accurately query whether the credential data is a valid credential, an embodiment of the present invention provides a method for recording abnormal credential data based on a blockchain. The so-called block chain is a new application mode of c...

Abstract

The embodiment of the invention discloses a data processing method and device based on a block chain, a storage medium and node equipment. The method comprises the following steps: receiving a requestfor adding additional information initiated by a terminal for target credential data in the block chain network, and verifying whether the target additional information is valid additional information according to the attribute information, if the target additional information is valid additional information, establishing an association relationship between the target additional information and the target voucher data, and storing the target additional information in the block chain network. Through the embodiment of the invention, the authenticity of recording the abnormal voucher data can be improved, so that whether the voucher data is a valid voucher can be accurately inquired.

Description

technical field [0001] The present invention relates to the field of security technology, in particular to a data processing method based on blockchain, a data processing device based on blockchain, a computer storage medium and a node device.
