Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

According to an aspect of the embodiments of the present invention, a method for updating a chain code identity is provided.

Fig. 1 is a schematic diagram of a main flow of a method for updating a chain code identity according to an embodiment of the present invention. As shown in fig. 1, the method for updating the same identifier of the chain code according to the embodiment of the present invention includes steps S101-S110.

S101: requesting chain code execution;

because the operation of each user can be concurrently written into the chain code in the whole operation process of the system, and then the processed operation key is put into the cache, the transaction information of each user is obtained firstly.

S102: acquiring a transaction ID;

s103: splicing a uniform prefix to the transaction ID;

s104: placing the identifier into a buffer pool;

and if the current block reaches the preset height or the time stamp reaches the preset value, the next operation is carried out. For each node of the block chain, when the same block height exists, the updated data of each node can be guaranteed to be uniform, and the uniformity and the reliability of data updating are guaranteed. However, in the block chain, there may be a large delay in data processing, and the operation cannot be executed later, so that a time stamp is set as another threshold, and the update work is executed when the time reaches the reference. The time stamp is selected by taking the time of the user submitting operation as a reference, so that the time consistency is ensured, and meanwhile, the uniformity and the reliability in data updating are also ensured.

S105: judging whether the block height reaches a preset value or the time stamp reaches a preset time;

s106: acquiring a public prefix of the identifier;

s107: acquiring an identifier needing to be updated according to the acquired public prefix and the module needing to be updated and calculated in the step S106;

s108: integrating the acquired identifiers, and performing addition, subtraction, multiplication and division or other operations on the values corresponding to the identifiers according to the operation specified by the user;

s109: deleting the mark of the completed integration operation; and

s110: the result obtained by the integration operation is written into the block chain.
