  Integrating on-chain and off-chain data storage for decentralised and
distributed information systems, such as blockchain, presents specific
challenges for providing transparency of data governance and ensuring data
integrity through stakeholder engagement. Current research on blockchain-based
supply chains focuses on using on-chain governance rules developed for
cryptocurrency blockchains to store some critical data points without designing
tailored on-chain governance mechanisms and disclosing off-chain
decision-making processes on data governance. In response to this research gap,
this paper presents an integrated data governance framework that coordinates
supply chain stakeholders with inter-linked on-chain and off-chain governance
to disclose on-chain and off-chain rules and decision-making processes for
supply chain transparency and integrity. We present a Proof-of-Concept (PoC) of
our integrated data governance approach and suggest future research to
strengthen scaling up and supply chain-based use cases based on our learnings.
