Problems solved by technology

[0003] However, traditional distributed databases are built based on server clusters, which rely on reliable servers and high-speed network bandwidth, resulting in high costs; at the same time, the data is controlled by the organization that operates the system, and database records can be tampered with at will, and it is easy to Attacked and illegally modified by hackers, data security cannot be guaranteed

Abstract

The invention discloses block chain node equipment and a data reading and writing-in method of a distributed database. By launching a transaction for binary data of keys and / or values on a block chain, and constructing a local index from the keys to transaction target information, the decentralized key-value database based on the block chain is achieved, and data writing-in and reading based on the key-value database are supported. The decentralized key-value database achieved through a block chain technology can run based on common network nodes, and any amendment records of data can be traced and inquired.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain node device and a data reading and writing method of a distributed database. Background technique [0002] Distributed database refers to the use of high-speed computer network to connect multiple physically dispersed data storage units to form a logically unified database; the basic idea of ​​distributed database is to disperse and store the data in the original centralized database to multiple channels. Network-connected data is stored on blockchain node devices for larger storage capacity and higher concurrent access. In recent years, with the rapid growth of data volume, distributed database technology has also developed rapidly. Traditional relational databases have begun to develop from centralized models to distributed architectures. Relational-based distributed databases retain traditional databases. Under the data model and basic characteristics, from...
