The invention discloses a method and device for synchronizing a relational database to a block chain. The method comprises the following steps of: forming a substrate; acquiring to-be-synchronized data from a relational database, and sending a message carrying the to-be-synchronized data through a message queue, converting the message into blockchain data by adopting a dynamic scripting language,writing the block chain data into a block chain; data synchronization from the relational database to the block chain is realized; non-involving distributed transaction issues, invasion into originalservice system is not needed. According to the method, the influence on the stability and the reliability of the original service system is avoided. The complexity of the original service system is not additionally increased. The problems that time and labor are wasted, the stability and the reliability of the original service system are influenced and the complexity of the original service systemis increased when the existing block chain network is butted with the service system are solved.
Description
technical field [0001] The invention relates to the technical field of computer applications, in particular to a method and device for synchronizing a relational database to a block chain. Background technique [0002] Since the advent of Bitcoin in 2008, after ten years of development, blockchain, a distributed, network-wide consistent, undeletable, and untamperable chained block storage structure, has become an unprecedented human bookkeeping And storage mode, creatively solves the credit problem in the process of large-scale human cooperation, makes the application of blockchain in decentralization and anti-counterfeiting traceability data tamper-proof become more and more abundant, and there are more and more scenarios that have been implemented, such as Using the distributed online database provided by the blockchain, the encrypted transaction data is shared by multiple parties, thereby providing a complete audit trail for cryptocurrency transactions; another example is...
