Technical Report on On-Ledger and Off-Ledger Data Management Standards

This draft report sets out to guide organisations, particularly small and medium-sized enterprises (SMEs), in managing blockchain data effectively by classifying information either on-ledger (placed directly on the blockchain) or off-ledger (stored externally but cryptographically linked). The research pursues three main objectives: to define clear standards for data classification, to align those standards with existing regulations and industry needs, and to offer practical recommendations that enhance security, interoperability, and compliance.
