Problems solved by technology

[0004]Aiming at the problem that the existing block chain ledger does not pay attention to the order of data records, in order to realize centralized data storage and improve user experience, the embodiment of this manual An index creation method, device, and equipment are provided, and the method is applied to a centralized database service provider that stores data through multiple data blocks, specifically including:

Embodiment approach

[0041] In this embodiment, although several time effective bits are sacrificed, the hash value of the data record can be read directly, and the block height of the data block can be identified by the specified serial number (ie, 000 in Table 2).

[0042]The above-mentioned index can be created immediately when the block is generated, or it can be created asynchronously. The index itself can be used for some search or statistical operations, for example, it is more convenient to count the number of data records in a certain period of time and avoid traversal counting from the data block.

[0043] By traversing all data blocks and writing corresponding data records in all data blocks into the index table, a completed index table corresponding to all user data can be obtained. In the above index table, each data record has both the block-forming time of being written into the block (the block-forming time of each data record in the same block is the same), and the order of being ...

Abstract

The invention discloses an index creation method, device and equipment. In a scene that a server centrally stores data records in a data block chain manner, each data block comprises a hash value of adata block itself determined by a hash value of a previous data block and the data records contained in the data block itself, and a provider of the data service cannot easily change the stored data.At the moment, the index table about the acceptance time sequence of the data records in the data block is created, so that the data records can be conveniently queried and traced, and the user experience is improved.

Description

technical field [0001] The embodiments of this specification relate to the field of information technology, and in particular, to an index creation method, device, and equipment. Background technique [0002] When using a block-chain ledger to store data, a data block often contains multiple data records, and it is difficult to see the order in which each data record is accepted in a general block-chain ledger. And when the data records are stored in the server in a centralized manner, the server often has some relationship with the order in which the data records are accepted. For example, the user's consumption record, or, based on the user's instruction, the service provider's operation record on a certain data or account, etc., the difference in the order of acceptance often leads to different results. [0003] Based on this, an index that can reflect the time sequence of data records accepted by the centralized service provider is needed. Contents of the invention ...
