In summary, in the above embodiments, the attribute of each endorsement node in the endorsement node set is set, the transaction data from the client is acquired, then the endorsement is performed on the transaction data based on the attribute of each endorsement node in the endorsement node set, and the attribute of each endorsement node in the endorsement node set may be further updated. According to the method and the device, the attribute of each endorsement node in the endorsement node set is set and the attribute of each endorsement node in the endorsement node set is updated, so that the privacy data can be endorsed only on a specific endorsement node according to the attribute of the endorsement node, and the protection of the privacy information is more comprehensive.
As shown in fig. 9, which is a schematic structural diagram of an embodiment 1 of a computer system according to the present disclosure, where the system is applied to a blockchain network, the blockchain network includes a plurality of nodes, and the plurality of nodes includes one or more endorsement nodes, and the computer system includes: a memory 901, a processor 902 and a computer program stored on the memory 901 and executable on the processor 902, the processor 902 when executing the program for performing:
acquiring transaction data from a client;
and endorsement is performed on the transaction data based on the attributes of each endorsement node in the endorsement node set.
The method comprises the steps of firstly obtaining transaction data generated by a client, for example, obtaining transaction price data, transaction quantity data and the like from the client.
And after the transaction data from the client is acquired, carrying out corresponding endorsement processing on the transaction data further according to the attribute of each endorsement node in the endorsement node combination in the block chain network. Wherein, the attribute of each endorsement node can be preset. Different endorsement nodes in the set of endorsement nodes may have different attributes depending on the actual needs of the transaction. Through different attributes, the endorsement node can perform data processing on transaction data from the client in different ways.
In summary, in the above embodiments, the transaction data from the client is first obtained, and then endorsement is performed on the transaction data based on the attribute of each endorsement node in the endorsement node set. According to the method and the device, the private data can be endorsed only on the specific endorsement node according to the attribute of the endorsement node, and the protection of the private information is more comprehensive.
It should be noted that, in the present specification, the embodiments are all described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other. For the device or system type embodiment, since it is basically similar to the method embodiment, the description is simple, and for the relevant points, refer to the partial description of the method embodiment.
It is further noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The steps of a method or algorithm described in connection with the embodiments disclosed herein may be embodied directly in hardware, in a software module executed by a processor, or in a combination of the two. A software module may reside in Random Access Memory (RAM), memory, Read Only Memory (ROM), electrically programmable ROM, electrically erasable programmable ROM, registers, hard disk, a removable disk, a CD-ROM, or any other form of storage medium known in the art.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present disclosure. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the disclosure. Thus, the present disclosure is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
