With the transition to Industry 4.0 factories have achieved significant gains in production with respect to quality, reliability, flexibility, and utilization of resources. Nonetheless, there are open challenges that shall be addressed when it comes to traceability of defects and automation actions that are interrelated with both optimization and security aspects along the production chain. Current industrial solutions use a centralized client-server architecture; however, if the central authority is undermined, the system can fail. In this regard, one of the most promising technologies is blockchain, as it is a decentralized technology based on a peer-to-peer network instead of a client-server model. In this paper, we propose a blockchain framework based on Ethereum platform, which is applied in three different production lines namely for antenna manufacturing, microelectronics, and elevators. Initially, we have three different private Ethereum networks, for each factory, with the Proof-of-Authority consensus mechanism. We have developed smart contracts for defect detection as well as firmware update for production equipment. As shown through experiments, the developed smart contracts have certain advantages compared to existing practises in terms of traceability and cyber-security. Furthermore, we have developed a blockchain API that connects the proposed framework with an industrial middleware platform and the overall OPTIMAI Industry 4.0 ecosystem. Experiments for each production line showcase the potential of our approach and it gains in terms of security, storage, traceability, and transparency.

“…Therefore, just in response to the above phenomenon, some researchers proposed the use of blockchain technology for the storage of food traceability data ( Wang et al., 2022a ). In the Bonde Thylstrup et al. (2022) , the author was concerned about the concept of accountability, explainability, and speculation, which disclose to the importance of traceability.…”

From flows towards updates: Security regimes and changing technologies for financial surveillance

‘Follow the money’ is currently the central principle of international financial security, although money itself is probably one of the most unlikely objects to make traceable. Two recent scandals around a security unit and the payment processor Wirecard show how existing systems of financial surveillance that seek to capture ‘flows’ of money for security purposes are either enabled or frustrated. While this current regime of financial surveillance adheres to demanding the free flow of money through financial infrastructures and various actors and intermediaries, new digital currencies build on a set type of ledger(s) in which money is stored as data. Hence, what we understand as money does not ‘flow’, but is rather updated. This change in the underlying infrastructure means that traceability does not need to be enacted; it is an intrinsic feature of digital currencies. With new central bank digital currencies (CBDC), the regime of financial security thus changes from the monitoring of financial flows and flagging of (potentially) illicit transactions towards the storage of financial data in (de)centralised ledgers. This form of transactional governance is engendered by shifting geopolitical agendas that increasingly rely on fractured instead of globalised financial infrastructures, thus making CBDCs themselves subject to security efforts.
