BITONE is a blockchain network that enables multiple audit nodes to verify data integrity using the self-developed 2DIVS system. The verified data is then stored in the blockchain using the IPFS method. 2DIVS, which stands for Distributed Data Integrity Verification System, is a concept of a blockchain network for data verification. Currently, most data is stored in centralized devices, making it reliant on the announcements of relevant companies or institutions for data integrity reporting. Although some cases involve third-party audits for verification, the reliability of the results cannot be guaranteed. Merely having multiple institutions or auditors check the integrity is also insufficient to establish reasonable trust. Data verification is a crucial aspect of various business groups and is applicable to many areas.
