Problems solved by technology
[0002]
In traditional financial transaction systems such as bond issuance systems, data is generally stored in the system builder, but for other participants, data storage and modification are opaque, so data is easily tampered with, resulting in The data is insecure, unreliable, and it is impossible to verify the authenticity of the data
Some of the existing technologies use blockchain technology to avoid data tampering, but the blockchain itself is not suitable for storing large data, which leads to storage pressure on the blockchain and affects system performance
[0003]
For the above problems, no effective solution has been proposed

The invention provides a block chain-based bond issuing data storage and verification processing method and device, a bond issuing participant node forms a block chain network, and the data storage method comprises the steps that the bond issuing participant node receives a data storage request in a bond issuing process; the first processing module detects whether the target storage data belongs to pre-configured data needing to be linked in an abstract mode or not; if yes, the target storage data and the corresponding retrieval key identifier are stored into a system constructor database, thetarget storage data is processed to obtain corresponding abstract information, and the retrieval key identifier and the abstract information are sent to a first block chain module; the first block chain module sends the retrieval key identifier and the abstract information to a block chain network, wherein the abstract information is used for providing data verification for the bond issuing participant. According to the technical scheme, the security and reliability of important and sensitive data in the bond issuing process are ensured, the storage pressure of the block chain is reduced, andthe performance is ensured.
Description
technical field [0001] The present invention relates to the technical field of data processing, in particular to a block chain-based method and device for bond issuance data storage and verification processing. Background technique [0002] In traditional financial transaction systems such as bond issuance systems, data is generally stored in the system builder, while for other participants, data storage and modification are opaque, so data is easily tampered with, resulting in The data is not safe, unreliable, and it is impossible to verify the authenticity of the data. Some of the existing technologies use blockchain technology to prevent data from being tampered with, but the blockchain itself is not suitable for storing large data, which causes storage pressure on the blockchain and affects system performance. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] The embodiment of the present invention provid...
