“…The work in [ 28 ] presents a solution adopting the blockchain to support the servitization of ice cream machines by exploiting smart contracts to ensure data validity related to machine usage. Similarly, in [ 29 ] the Blockchain is used to allow machine owners to share idle machines capacity by securely storing in the blockchain relevant events related to machine usage. The work in [ 30 ] supports actors of the manufacturing supply chain to make agreements and payments based on the blockchain in a secure and distributed manner, without an intermediary.…”

Blockchain technology plays a pivotal role in the undergoing fourth industrial revolution or Industry 4.0. It is considered a tremendous boost to company digitalization; thus, considerable investments in blockchain are being made. However, there is no single blockchain technology, but various solutions exist, and they cannot interoperate with one each other. The ecosystem envisioned by the Industry 4.0 does not have centralized management or leading organization, so a single blockchain solution cannot be imposed. The various organizations hold their own blockchains, which must interoperate seamlessly. Despite some solutions for blockchain interoperability being proposed, the problem is still open. This paper aims to devise a secure solution for blockchain interoperability. The proposed approach consists of a relay scheme based on Trusted Execution Environment to provide higher security guarantees than the current literature. In particular, the proposed solution adopts an off-chain secure computation element invoked by a smart contract on a blockchain to securely communicate with its peered counterpart. A prototype has been implemented and used for the performance assessment, e.g., to measure the latency increase due to cross-blockchain interactions. The achieved and reported experimental results show that the proposed security solution introduces an additional latency that is entirely tolerable for transactions. At the same time, the usage of the Trusted Execution Environment imposes a negligible overhead.

“…We first defined the actors and corresponding use cases. The research in [ 1 ], for example, defines three application actors in their machine-sharing economy example on process traceability in distributed manufacturing: client, owner, and operator. We added two additional actors.…”

“…However, the expectations reach far beyond this. From the business perspective, manufacturing and supply chains are relatively static, driven by long-term agreements, and rely on a high level of trust between participants [ 1 ]. Machine-sharing economy principles and servitization impose a mix of new business and technical requirements for future digitalization.…”

“…Second, a service marketplace must be established, possibly automated, and well-integrated with existing enterprise resource planning and manufacturing information systems. In [ 1 ], the authors presented a prototype of a decentralized machine-sharing economy (MSE) approach. A skill and capability model describes the available machine capacities following the DIN 8580:2003–09 standard, which defines the manufacturing process classes of a technical system performing manufacturing process [ 13 ].…”

Blockchain ecosystems are rapidly maturing and meeting the needs of business environments (e.g., industry, manufacturing, and robotics). The decentralized approaches in industries enable novel business concepts, such as machine autonomy and servitization of manufacturing environments. Introducing the distributed ledger technology principles into the machine sharing and servitization economy faces several challenges, and the integration opens new interesting research questions. Our research focuses on data and event models and secure upgradeable smart contract platforms for machine servitization. Our research indicates that with the proposed approaches, we can efficiently separate on- and off-chain data and assure scalability of the DApp without compromising the trust. We demonstrate that the secure upgradeable smart contract platform, which was adapted for machine servitization, supports the business workflow and, at the same time, assures common identification and authorization of all the participants in the system, including people, devices, and legal entities. We present a hybrid decentralized application (DApp) for the servitization of 3D printing. The solution can be used for or easily adapted to other manufacturing domains. It comprises a modular, upgradeable smart contract platform and off-chain machine, customer and web management, and monitoring interfaces. We pay special attention to the data and event models during the design, which are fundamental for the hybrid data storage and DApp architecture and the responsiveness of off-chain interfaces. The smart contract platform uses a proxy contract to control the access of smart contracts and role-based access control in function calls for blockchain users. We deploy and evaluate the DApp in a consortium blockchain network for performance and privacy. All the actors in the solution, including the machines, are identified by their blockchain accounts and are compeers. Our solution thus facilitates integration with the traditional information-communication systems in terms of the hybrid architectures and security standards for smart contract design comparable to those in traditional software engineering.
