Interoperability framework to enhance the DLT based systems integration with enterprise IT systems.

Abstract

Distributed ledger technology (DLT) has generated tremendous interest due to its popular application to Bitcoin and other cryptocurrencies. Despite its enormous potential business benefits and even greater hype, DLT never attracted significant investment and its widespread implementation failed to occur. One of the most recognised reasons is the lack of an integration framework for integrating DLT-based systems with centralised or non-DLT information technology (IT) systems.

This research endeavours to fill this gap by designing a DLT interoperability framework (DIF). This framework is based on the interoperability principles derived from integrated DLT-based solutions and modern organisations' integration needs and practices. DIF enables organisations to design interoperability architecture and integrated solutions for enterprise implementation. Based on the DIF, this research also developed and instantiated a Hyperledger Fabric DLT solution prototype (HDSP) on Amazon Web Services (AWS) for the manuka honey supply chain (MHSC) use case.

The research utilised design science research (DSR) methodology to develop the DIF and HDSP. Iterative artefact evaluations were undertaken using formative (ex-ante), summative (ex-post), maturity model for enterprise interoperability (MMEI), IT professional evaluation, and artefact instantiation and demonstration techniques suggested in the DSR. The DIF, HDSP and their evaluation provide a pathway for organisations to design and implement integrated DLT-based solutions. The knowledge generated and utilised in this research provides a robust theoretical foundation for building and implementing such integrated solutions.
