This article explores the challenges and opportunities of enhancing blockchain interoperability and intraoperability in collaborative enterprises (CE) through a standardized architecture perspective. Blockchain technology, particularly Distributed Ledger Technologies (DLT), is increasingly adopted in CE to enable secure, transparent, and efficient data sharing among organizations. However, the inability of different blockchains to communicate with each other poses a significant challenge to the mainstream deployment of blockchains in CE. This study presents a standardized architecture to support DLT interoperability and intraoperability within CE. A structural review was conducted, followed by design science research methodology to validate the architecture. Blockchain interoperability refers to the ability of different blockchain platforms to exchange data and communicate with each other, while intraoperability refers to the ability of a single blockchain platform to interact with other blockchain platforms to facilitate data exchange. The study highlights the importance of blockchain interoperability and intraoperability in CE, as they enable secure state transitions across diverse blockchains and support the broader adoption of blockchain technology. The study also identifies the need for an approach that safeguards the unique characteristics of blockchains and effectively manages state changes such as data append and validation procedures. The study discusses various approaches to achieving blockchain interoperability and intraoperability, including notary schemes, sidechains, hash-locking, relay solutions, bridging techniques, blockchain routers, and distributed private key control (DPKC). These approaches aim to enable cross-platform communication and data exchange between different blockchain platforms. However, the study also highlights the challenges associated with achieving blockchain interoperability and intraoperability, including the need for a unified standardization in blockchain development and the limitations of existing approaches in terms of decentralization and scalability. The study concludes that a standardized architecture is needed to support blockchain interoperability and intraoperability in CE. This architecture should enable secure and efficient data exchange between different blockchain platforms while preserving the unique characteristics of each blockchain. The study also emphasizes the importance of further research in this area to develop practical solutions that enable seamless integration of blockchain technology in CE.This article explores the challenges and opportunities of enhancing blockchain interoperability and intraoperability in collaborative enterprises (CE) through a standardized architecture perspective.
