The breakthrough of Distributed Ledger Technologies (DLT) has enabled the emergence and implementation of a wide range of digital platforms in Virtual Enterprises (VE) which collaborate to provide digital services. DLT has the potential to revolutionize VE by offering transparent, decentralized, trustworthy, data provenance, reliable, and auditable features. Yet, the full deployment of DLT systems and digital platforms is still limited since some systems are operating in isolation. Hence, DLT interoperability is one of the challenges inhibiting widespread adoption of DLT platforms. DLT interoperability represents the ability for one distributed ledger platform to interact and share data with other legacy digital applications. It is inevitable to orchestrate these digital platforms fragments by introducing a cross-DLT platform integration to govern data usage within VE. Presently, already proposed approaches for DLT interoperability such as naive relay, sidechain, oracle solutions notary scheme, or relay chain are mostly not employed as they are either resource-intensive or too expensive to operate. Therefore, this paper presents a layered architecture that aids interoperability of DLT, and digital platforms based on IOTA Tangle. Design science method is adopted, and case demonstration is carried out to show how IOTA Tangle enable VE to provide an innovative virtual asset payment platform for seamless electric mobility as a service to clients. IOTA was employed as the DLT platform due to its data traceability, immutability, and tamper-proof features which allow for verification of integrity of data. IOTA offers flexibility and performance to support a reliable digital solution. Findings from this study presents a layered architecture that aids IOTA Tangle to make requests, inter-communicate, and share data via RESTful application programming interface as gateway with other external digital platforms deployed by VE to achieve an interoperable eco-system.

分布式账本技术 (DLT) 的突破使得虚拟企业 (VE) 中出现并实施了广泛的数字平台，这些平台协作提供数字服务。DLT 有可能通过提供透明、去中心化、值得信赖、数据来源、可靠和可审计的特性来彻底改变 VE。然而，由于一些系统是孤立运行的，DLT 系统和数字平台的全面部署仍然受到限制。因此，DLT 互操作性是阻碍 DLT 平台广泛采用的挑战之一。DLT 互操作性代表了一个分布式账本平台与其他传统数字应用程序交互和共享数据的能力。通过引入跨 DLT 平台集成来管理 VE 中的数据使用，来编排这些数字平台片段是不可避免的。目前，已经提出的 DLT 互操作性方法，如朴素中继、侧链、预言机解决方案公证人方案或中继链大多没有采用，因为它们要么资源密集，要么运营成本太高。因此，本文提出了一种分层架构，有助于 DLT 和基于 IOTA Tangle 的数字平台的互操作性。采用设计科学的方法，并进行案例演示，展示了IOTA Tangle如何使VE提供创新的虚拟资产支付平台，为客户提供无缝电动出行即服务。IOTA 因其数据可追溯性、不变性、和防篡改功能，允许验证数据的完整性。IOTA 提供灵活性和性能来支持可靠的数字解决方案。本研究的结果提出了一种分层架构，可帮助 IOTA Tangle 通过 RESTful 应用程序编程接口作为网关与 VE 部署的其他外部数字平台发出请求、相互通信和共享数据，以实现可互操作的生态系统。
