Problems solved by technology

The wide application of blockchain technology provides an effective solution for smart community information management. In related technologies, blockchain technology is applied in the construction of smart communities, but it mainly solves the problem of synchronizing information in the community. However, due to the rapid update of information in the community, only by directly synchronizing the community information may lead to the difficulty of tracing the information updated each time.

Abstract

The invention provides an information management method and system based on a block chain, a block chain node and a computer readable storage medium, and the method comprises the steps: a first building area node taking updated resident information as a new first block to be stored in a first storage area after the first building area node receives the updated resident information in a first building area every time; the first building area node calculating information entropies of all first blocks in the first storage area of the first building area node; the first building area node judging whether the information entropy is greater than a preset threshold; and if the the information entropy is greater than the preset threshold value, the first building area node packaging all the first blocks into second blocks and broadcasting the second blocks to all second building area nodes in the block chain, so that all the second building area nodes store the second blocks in respective second storage areas. According to the embodiment of the invention, the problem that the information updated each time in a community is difficult to trace due to direct synchronization of the community information can be solved at least.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a blockchain-based information management method, a blockchain-based information management system, a blockchain node, and a computer-readable storage medium. Background technique [0002] With the continuous development of the economy, the demand for smart communities has gradually increased. How to realize the Internet-based management of residents in the community, realize the safe and controllable management of information, and establish a new smart community has become the direction of community development. The extensive application of blockchain technology provides an effective solution for information management in smart communities. In related technologies, blockchain technology is applied in the construction of smart communities, but it mainly solves the problem of synchronization of information in the community. However, due to the rapid update ...
