“…Third, IS research has often focused on technical issues of the underlying smart contract-enabling blockchain technology in isolation, such as the lack of privacy, security or scalability and different development standards (Atzei et al, 2017; Christidis and Devetsikiotis, 2016; Coblenz et al, 2019; Destefanis et al, 2018). For example, previous research has developed protocols that allow for preserving data integrity (Nugent et al, 2016) or privacy (Chanson et al, 2017; Kosba et al, 2016) features.…”

Blockchain technology has enabled so-called smart contracts between different parties on a decentralized network. These self-enforceable and self-executable computerized contracts could initiate a fundamental paradigm shift in the understanding and functioning of our legal practices. Opportunities for their application are increasingly understood, and numerous tests of feasibility have been completed. However, only very few use cases have yet been implemented at scale. This article—as the first of its kind—comprehensively analyzes the underlying challenges and locates a key reason for the slow adoption in the discrepancy between legal requirements and IT capabilities. Our work combines a wide range of academic sources and interviews with 30 domain experts from IT, the legal domain and private industry. First, we establish that smart contracts still fall within the boundaries of the general legal framework. We then systematically dissect current shortcomings of smart contracts on three distinct levels, namely, (1) how smart contracts are likely to cause conflicts with existing laws, (2) how smart contracts are intrinsically limited on an individual contract level and (3) how they are impeded by their current technical design. Across those levels, we dissect 20 distinct issues concerning the current implementation of smart contracts for which we derive potential remedies. We further outline implications for policy-makers as well as IT management, and examine how information systems research can play an important role in advancing smart contracts. Finally, we show how managerial and organizational issues might represent an ongoing challenge for the widespread adoption of smart contracts.

“…A few studies explore whether or not blockchain technology may reduce information asymmetries in the automotive market by creating a blockchain-based vehicle history. Odometer values can be securely stored in a public blockchain system to address the problem of odometer fraud by using sensor data from vehicles (Chanson, Bogner, Bilgeri, Fleisch, & Wortmann, 2019;Chanson, Bogner, Wortmann, & Fleisch, 2017). Notheisen et al (2017) propose a public blockchain-based car register system and show that it is capable to reduce transaction risk resulting from immutability of blockchain transactions and minimize quality uncertainty by providing reliable, transparent, and complete vehicle history.…”

“…Jabbar and Bjørn (2017) have conducted an ethnographic study on entrepreneurs working on blockchain infrastructure and products, but their scope does not extend very much to the end-user [37]. Chanson et al (2017) have implemented a blockchain-based system for preventing automobile odometer fraud, but an investigation of "user interaction with the system" is left for future work [12]. Jaffe et al (2017) have described a system of financial incentives to promote urban cycling, and presented a proofof-concept implementation where bicycle-mounted sensors communicate over a cellular network with a blockchain-based database and computing platform [38].…”

This paper explores the contrasting notions of "permanance and disposability," "the digital and the physical," and "symbolism and function" in the context of interaction design. Drawing from diverse streams of knowledge, we describe a novel design direction for enduring computational heirlooms based on the marriage of decentralized, trustless software and durable mobile hardware. To justify this concept, we review prior research; attempt to redefine the notion of "material;" propose blockchain-based software as a particular digital material to serve as a substrate for computational heirlooms; and argue for the use of mobile artifacts, informed in terms of their materials and formgiving practices by mechanical wristwatches, as its physical embodiment and functional counterpart. This integration is meant to enable mobile and ubiquitous interactive systems for the storing, experiencing, and exchanging value throughout multiple human lifetimes; showcasing the feats of computational sciences and crafts; and enabling novel user experiences.
