Decentralized finance (DeFi) presents individuals with financial autonomy and opens numerous avenues within the financial services sector. However, there are obstacles that impede its broader adoption. Many of these hurdles cannot be exclusively addressed through technical means and stem from issues related to the absence of a consistent, enduring...

This paper investigates the potential of blockchain-based fan tokens, a class of crypto asset that grants holders access to voting on club decisions and other perks, as a mechanism for stimulating democratized decision-making and fan engagement in the sports and esports sectors. By utilizing an extensive dataset of 3576 fan token polls, we reveal t...

This study undertakes an in-depth examination of how football matches and related sporting performance influence the intraday financial performance of corresponding blockchain-based fan tokens. Utilizing an event study encompassing eight distinct fan tokens and 325 football matches, we find a statistically significant average decline of 0.8% in fan...

Identities are an essential aspect of information systems (IS) as they allow users of a digital ecosystem to interact, build trust, and form relationships. Decentralized finance (DeFi) is a digital, blockchain-based ecosystem that has seen tremendous growth in the last years, however, struggles with current identity implementations. While academics...

In an era where Decentralized Finance (DeFi) is becoming increasingly integral to the broader financial ecosystem, Decentralized Autonomous Organizations (DAOs) have proven to be key players. Currently commanding a collective market capitalization of over USD 14 billion, their financial backbones—DAO treasuries—merit meticulous study. This study ai...

Blockchain-based fan tokens provide token holders with certain rights, incentivizing fan engagement and decision-making within sports organizations. Despite the recent surge in interest, acceptance and technical advancement, a profound understanding of the technical, functional, and conceptual foundations of fan tokens is still lacking, necessitati...

Blockchain-based tokens seek to overcome the friction and opaqueness of the legacy financial infrastructure in the company funding process, particularly in the early-stage and equity crowdfunding domain. While Initial Coin Offerings and Security Token Offerings proposed a solution for crowdfunding, early-stage companies still face challenges in usi...

While Decentralized Finance (DeFi) has the potential to emulate and, indeed, outperform existing financial systems, it remains a complex phenomenon yet to be extensively researched. To make the most of this potential, its practitioners must gain a rigorous understanding of its intricacies, as must information systems (IS) researchers. Against this...

Bitcoin and other cryptocurrencies built on blockchains have increasingly attracted investors in recent years. Motivated by the opportunities of this technology, blockchain-based applications in various sectors have also been explored. Yet, so far, finance-related applications have arguably remained the most advanced and relevant area of blockchain...

Blockchain innovations such as digital fan tokens and non-fungible tokens (NFTs) have garnered notable attention in the sports industry, yet the wider industry is struggling to keep up with the pace of digitalization. To harness the potential of blockchain technology, sports management practitioners and information systems (IS) researchers need to...

As blockchain development continues at an ever-increasing pace, an increasing number of individual actors and organizations throughout entire economies get into contact with the technology. Furthermore, the growing collaboration of companies, customers, suppliers, and other actors is evolving into a multilateral network between the parties engaged...

Countless decentralized finance (DeFi) applications of the past years have suffered from the high volatility and speculative behavior surrounding their underlying crypto assets. While the academic debate has been flourishing in these areas, Decentralized Autonomous Organizations (DAOs) have not received as much attention. This is the case even thou...

The rising popularity of blockchain has cleared the path for developing numerous decentralized finance (DeFi) applications. However, insurance solutions for DeFi applications are still missing. Therefore, this article presents a smart contract-based P2P credit default insurance solution using the Design Science Research Method. The design presents...

Due to blockchains' intrinsic transparency and immutability, blockchain-based applications are challenged by privacy regulations, such as the EU General Data Protection Regulation. Hence, scaling blockchain use cases to production often fails to owe to a lack of compliance with legal constraints. As current research mainly focuses on specific use c...

Due to a steeply growing number of energy assets, the increasingly decentralized and segmented energy sector fuels the potential for new digital use cases. In this paper, we focus our attention on the application field of asset logging, which addresses the collection, documentation, and usage of relevant asset data for direct or later verification....

Most central banks in advanced economies consider issuing central bank digital currencies (CBDCs) to address the declining use of cash and to position themselves against increased competition from Big Tech companies, cryptocurrencies, and stablecoins. One crucial design dimension of a CBDC system is the degree of transaction privacy. Existing solut...

Bei der Blockchain-Technologie handelt es sich um ein dezentrales elektronisches Register für digitale Transaktionen. Zu den Eigenschaften der Technologie zählen u. a. eine hohe Manipulationsresistenz, welche Vertrauen in digitale Daten erzeugen kann, sowie die Möglichkeit, Prozesse und Transaktionen, ohne Intermediär abzuwickeln. Diese besonderen...

This paper aims to elaborate on the optimization of two particular cryptocurrency portfolios in a mean-variance framework. In general, cryptocurrencies can be classified to as coins and tokens where the first can be thought of as a medium of exchange and the latter accounts for security or utility tokens depending upon its design. Against this back...
