A system configuration data management method based on block chain and smart contract

Abstract

The invention discloses a system configuration data management method based on block chain and smart contract, which relates to the field of block chain system. The method steps of the present invention are: (1) Writing configuration data into the account book: writing the configuration data into blocks of the blockchain network to form a decentralized configuration data account book. (2) Network nodes synchronize ledger data: all information nodes obtain and save a copy of the ledger from nearby nodes through the P2P protocol. (3) Network nodes read configuration data in the ledger: each information node directly reads a copy of the ledger to obtain configuration data. (4) Update configuration data in batches through smart contracts. The present invention can effectively avoid information node configuration data errors caused by network communication and malicious tampering, and can also greatly simplify the operation of updating configuration data for a large number of information nodes. The method is simple and the entire system process is safe and stable. , Accurate characteristics.

Description

technical field [0001] The invention relates to the field of block chain systems, in particular to a system configuration data management method based on block chains and smart contracts. Background technique [0002] In an information system or Internet of Things system based on a large-scale multi-node distributed network environment, different information nodes have different functions and require different configuration data. Therefore, different types of information nodes need to use different The configuration data for system configuration. [0003] In the prior art, the solution is mainly to establish a centralized configuration data management center system. In the configuration data management center system, it is necessary to perform classification management, configuration data item management, and configuration data synchronization and update management for each information node. [0004] However, there are also some problems in the above-mentioned centralized c...

But in this way, there will be a risk that the configuration data of an information node will be maliciously tampered with by the outside

[0007] 3. Since the configuration data of all nodes needs to be synchronized with the configuration data management center, once the data in the configuration data management center is maliciously tampered with, it will cause a large area of ​​system failure, with extremely serious consequences

[0008] 4. When it is necessary to update the configuration data of a large number of information nodes, the whole process is lengthy and complicated, and it is necessary to continuously monitor whether each node has successfully synchronized the new configuration data, which increases the complexity of the system
