Distributed ledger technology (DLT) is increasingly proposed as a powerful tool to address the social and ecological challenges in the Global South. DLTs are opening up possible futures, one of which is a wave of infrastructure decentralization with common-centric and cosmo-local production. Shared logistics and supply chains for a circular economy, with collaborative and networked ‘flow’ accounting allow the integration of contributive logics as well as the integration of social and ecological externalities, including practical knowledge on resource use limitations linked to planetary boundaries, as an integral part of ecosystems of productive collaboration. Indeed, DLTs remove the need for central intermediaries to validate transaction between parties, who instead place their trust in the encrypted, disintermediated system software. DLTs can be designed as a new unencloseable (non-commodifiable) medium of communication, which could lead to radically new forms of cooperation, organization, and governance. Yet these revolutionary possibilities will not be realized unless technologists consciously and strategically design systems redistributing sovereignty from elites to the people in financial, service and national infrastructures. This paper concludes with a critical examination of the application of DLT in Puerto Rico and how DLTs could alter the production and exchange of “value” in service of a global popular sovereignty.
Cloud Manufacturing is a manufacturing paradigm that focuses on collaboration and resource utilization. Until recently, little research has been done to combine the perspectives of cloud manufacturing and digital platform ecosystems. In the cloud manufacturing paradigm, the cloud coordinator takes up the dual role of a matchmaker and a platform owner, though, so it is interesting to research how any power dominance of the platform owner can be avoided. To do so, three dimensions of platform governance suggested by Tiwana 2014 – pricing policies, decision rights, and control – were considered in this contribution to recommend a fair value distribution mechanism for platform ecosystems in cloud manufacturing. Requirements for such a solution are formulated in this contribution and design patterns satisfying these requirements are derived. We propose using tokens administrated by distributed ledger technologies and smart contracts to enable a special split revenue scheme that satisfies the
An increasing amount of use cases is discovered for blockchain technology, since it promises tamper-proof recording of product-related data. It has the potential to improve the reliability of information management for whole supply chains and thus enables new ecologically and economically service offerings. Integrating products and services into one marketable bundle is no new concept and is referred to as product-service systems (PSS). Therefore, the methodical integration of knowledge on sustainable businesses, PSS and blockchain is a promising approach to overcome current barriers to achieve an applicable circular economy. Our study contributes a structured literature review on ongoing research in the field of sustainability-focused blockchain applications. From this, we elaborate a holistic perspective by the integration of key concepts from two additional literature reviews for blockchain and PSS. Asa result, we point out potential benefits and present the effect of blockchain on sustainable PSS with a product-life cycle model.

Implementing a circular economy business model which is profitable for businesses operating physical assets, while at the same time does not conflict with strategic goals of environmental policies can be a complex and risky undertaking for a single entity, especially if the asset operator is a small-to-medium enterprise (SMEs). To mitigate this, a collaborative circular economy business model is proposed, where the circular economy cycle is materialized by assets transitioning between asset operators on a demanddriven approach. Demand itself is partially based on the asset's state, which is described by its circular properties (location, condition, availability). The asset state and its transition between operators can be monitored by auditors and governmental regulators to ensure asset integrity and compliance with environmental targets. This common view of asset state between all parties can be enabled by blockchains and smart contracts, which can provide the underlying technology to share data with integrity, while simultaneously offering more efficient interoperability between participants. To demonstrate how this could be achieved, a conceptual asset record access and sharing mechanism is presented which is suitable for regulated environmental jurisdictions.
According to Byron Kennard , Executive Director of the Center for Small Business and the Environment , the Industrial Age was concerned with large scale, highly centralized production which often damaged the environment (e.g., steel production). 1 On the other hand the Post-Industrial Age is concerned with decentralized technology and distributed production which are cleaner, more efficient, and safer. Here the focus is on flexibility, innovation, and the concept that “less is more”. For example, laptops are smaller and more portable than desktop computers, cell phones are smaller, more powerful, and more transportable than traditional phones, automobile manufacturing currently emphasizes more flexible design and production techniques, greater fuel efficiency and increased safety.
