“…Users could decide on which personal online data storage systems they want to manage their data and who can access what kind of data. Such individual data controllership solutions would invert the logic of data transfer in a user-friendly way, reduce lock-in effects and could promote data-driven innovation [24,28,40].…”

For almost three years, the General Data Protection Regulation (GDPR) has been granting citizens of the European Union the right to obtain personal data from companies and to transfer these data to another company. The so-called Right to Data Portability (RtDP) promises to significantly reduce switching costs for consumers in digital service markets, provided that its potential is effectively translated into reality. Thus, of all the consumer rights in the GDPR, the RtDP has the potential to be the one with the most significant implications for digital markets and privacy. However, our research shows that the RtDP is barely known among consumers and can currently only be implemented in a fragmented manner—especially with regard to the direct transfer of data between online service providers. We discuss several ways to improve the implementation of this right in the present article.

“…Distributed ledgers enable the management of digital assets without the necessity of a trusted third party to a certain extent. It is possible to represent ownership of realworld assets (e.g., cars or houses) using tokens, which can be implemented as a smart contract [147]. However, it is challenging to create and deploy such tokens manually.…”

Smart contracts are a promising means of formalizing and reliably enforcing agreements between entities using distributed ledger technology (DLT). Research has revealed that a significant number of smart contracts are subject to programming flaws, making them vulnerable to attacks and leading to detrimental effects, such as asset loss. Researchers and developers call for a thorough analysis of challenges to identify their causes and propose solutions. To respond to these calls, we conducted two literature reviews and diverse expert interviews and synthesized scattered knowledge on challenges and solutions. We identified 29 challenges (e.g., code visibility, code updateability, and encapsulation) and 60 solutions (e.g., gas limit specification, off-ledger computations, and shadowing). Moreover, we developed 20 software design patterns (SDPs) in collaboration with smart contract developers. The SDPs help developers adjust their programming habits and thus support them in their daily development practices. Our results provide actionable knowledge for smart contract developers to overcome the identified challenges and offer support for comparing smart contract integration concepts across three fundamentally different DLT protocols (i.e., Ethereum, EOSIO, and Hyperledger Fabric). Moreover, we support developers in becoming aware of peculiarities in smart contract development and the resulting benefits and drawbacks.

“…From a technological perspective, it is crucial to understand how the respective blockchain components will (independently) evolve. For example, this pertains to advances in cryptography, zeroknowledge proofs, or cross-ledger interoperability [29], all of which can substantially transform the technical solutions that can be built upon them. From an application perspective, it is the innovative features of use or business cases that need to be researched, while from an impact perspective, the respective consequences for business, economy, and society deserve further investigation.…”

Exploring the Next Wave of Blockchain and Distributed Ledger Technology: The Overlooked Potential of Scenario Analysis

Blockchain is predicted to disrupt industries, economies, and societies. The properties of distributed ledgers allow the creation of immutable data structures that facilitate shared access in real time and enable a plethora of innovative applications. However, blockchain is not a uniform technology but rather a bundle of evolving components whose implications are notoriously hard to predict. At present, it is not clear how current trends will evolve, with technical evolution, legislation, and public policy being three contingency factors that make ongoing disruptive transformations particularly hard to predict. In light of blockchain’s potential disruptive impact, it is surprising that scenario analysis has hitherto been largely ignored in academic research. Therefore, in this paper, we introduce the technique, clarify several misconceptions, and provide examples illustrating how this method can help to overcome the limitations of existing technology impact research. We conclude that if applied correctly, scenario analysis represents the ideal tool to rigorously explore uncertain future developments and to create a comprehensive foundation for future research.
