Blockchain implications within the sustainability domain are rapidly arousing the interest of researchers and institutions. However, despite the avalanche of articles, papers, and recently published books, innovation in the blockchain domain is still heavily influenced by light literature, such as news, articles, opinion posts, and white papers. Lacking a homogeneous literature background, case studies often fall into storytelling, providing mere descriptions of the facts according to the writers’ impressions and opinions. We therefore investigate blockchain adoption for sustainable purposes through a case study while remaining firmly grounded in three main theoretical literature streams: knowledge management, knowledge infrastructure, and trust. Since blockchain interaction with the real world is managed by oracles, addressing the oracle problem is essential in order to evaluate the effectiveness of blockchain for sustainability issues. However, to the best of the authors’ knowledge, no other paper has efficiently addressed this subject or even mentioned it. Recognizing its scarce consideration in the literature, the oracle problem will be analyzed in both theoretical and practical terms, thereby providing a way to solve the issues related to non-fungible products in the supply chain. Choice over the selected case study was made in light of the divergence in motives for the adoption of blockchain (economic over social), which makes the results more inferable at a broader scale and offers an insight into how sustainable innovations can also be economically viable.

Purpose: To further extend the understanding of the aggregating functions of an entrepreneurial business network, this paper attempts to explore the antecedents enabling the organisation of diverse entrepreneurs to engage in a collaborative inter-firm business network project. This paper also elucidates the development of the relational capabilities and performance of entrepreneurial business networks.Design/methodology/approach: An explorative, longitudinal case study design is employed to analyse an Italian agricultural business network, which comprised a group of local small- and medium-sized enterprises (SMEs). Using the network as the focus of analysis, the case study draws insights from key informants comprising the network management team and the entrepreneurs who make up the membership of the business network.Findings: The results of the study provide critical factors for successful organisation of inter-firm engagement. Although these factors are not mutually exclusive, the results show that organising for inter-firm engagement in an entrepreneurial business network context positively influenced the network relational performance and entrepreneurs' innovation capabilities.Originality/value: The paper extends current understanding of inter-organisational engagement and illuminates the antecedents enabling the development of network relational dynamics capabilities. The empirical results provide unusual insights into the aggregating roles of an entrepreneurial business network, giving practitioners practical insights into managing a successful inter-organisational collaborative project. Using the relevant theoretical frameworks, the study empirically tests the organisation solutions relevant to literature on inter-firm engagement in a business network context and addresses the organisation solutions' interrelationship and linkages to entrepreneurial network relational performance in terms of knowledge practice, information and resources sharing and innovation.

On the basis of a four‐year exploratory study of a mandatory information systems implementation by an Italian, multibillion‐dollar dairy cooperative with 2200 members, this paper describes how key stakeholders engage in dynamic transformation processes that shape the technology, the users' practices and the organisation itself. In doing so, this study responds to calls for process‐oriented longitudinal explorations and suggests an alternative path of adoption in which the technology becomes the reification of a bi‐directional discourse about the transformation of practices for the entire network of organisations. In presenting this alternative path, this study unveils a five‐phase change process that both altered perceptions of the technology and its possibilities at the same time resolving tensions among the drivers and users of the mandated system. © 2016 John Wiley & Sons Ltd
