Embodiment Construction

[0015] Various exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. The flowchart and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of methods and systems according to various embodiments of the present disclosure. It should be noted that each block in a flowchart or a block diagram may represent a module, a program segment, or a part of a code, and the module, a program segment, or a part of a code may include one or more An executable instruction for a specified logical function. It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or they may sometimes be executed in the reverse order, depending upon the functionality involved. It should also b...

Abstract

The embodiment of the invention provides a block chain data indexing method and device. The method comprises the following steps: receiving transaction information and an index identifier associated with the transaction information; determining whether an index list associated with the index identifier exists in an index list set of a block chain; and in response to the result that the index list associated with the index identifier exists in the index list set of the block chain, adding a new item associated with the transaction information to the index list. By means of this manner, the inquiry efficiency of the block chain can be greatly improved, and meanwhile the effective support of complex inquiry (for example, range inquiry or condition inquiry) can be provided at the same time.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the technical field of data indexing, and more specifically relate to a blockchain data indexing method and device. Background technique [0002] Blockchain is a decentralized storage and computing technology, which generates persistent and unmodifiable records by superimposing encrypted data blocks in chronological order, and will be stored in each node of the blockchain network, It enables collective maintenance of a reliable database in a decentralized manner. Each data block contains system data within a certain period of time, and generates data fingerprints to verify the validity of its information and link to the next database block. Therefore, the blockchain has technical advantages in terms of data tamper resistance, transparency and decentralization. [0003] In existing blockchain systems, the basic way of data storage is usually key-value storage, that is, for each data stored on t...
