Enabling interoperable distributed ledger technology with legacy platforms for enterprise digitalization

ABSTRACTPresently to achieve enterprise digitalization technologies such as Distributed Ledger Technologies (DLT) has now been deployed to support digital services provided by enterprises. But several challenges in DLTs remain to be addressed, including the interoperability, standardization, and integration. Therefore, this study provides theoretical and practical understanding of DLT interoperability and identified the factors that influence the interoperability of DLTs. Also, an architecture is designed to shows how interoperability can be achieved in DLTs and legacy systems supported by Application Programming Interface (API). A case study is presented to illustrate the applicability of the architecture to support a digital energy marketplace.KEYWORDS: Enterprise digitalisationdistributed ledger technologiesinteroperabilityarchitecture modellingIOTA Tanglecase scenario AcknowledgementSpecial thanks to +CityxChange and Department of Computer Science, Norwegian University of Science and Technology, NTNU who sponsored the post-doctoral fellowship for the author.
