An Accounting Ledger System Using the Hyperledger Fabric-Based Blockchain.

Data related to money, or in other words, financial data, is encrypted as well as obfuscated and stored through various processes. The validity of this data can then be verified by using corresponding values. In this paper, chaincode generation, storage, and validation were used to verify whether the input data is reliable using a blockchain open source based on Hyperledger Fabric. The user has a hash value for the membership fee paid by himself/herself, is able to use the hash value to check whether the correct data was entered or not, and/or to detect the presence of irregularities. This allows transparent disclosure of the account book while corresponding data is provided with the function that only users belonging to a specific group can check, resulting in increased financial reliability within each group.
