In this article, we give a short introduction to cryptocurrencies and blockchain technology. The focus of the introduction is on Bitcoin, but many elements are shared by other blockchain implementations and alternative cryptoassets. The article covers the original idea and motivation, the mode of operation and possible applications of cryptocurrenc...

We characterize various currencies according to their control structure, focusing on cryptocurrencies such as Bitcoin and government-issued fiat money. We then argue that there is a large unmet demand for a liquid asset that allows households and firms to save outside of the private financial sector. Central banks could offer such an asset by simpl...

Full Paper on SSRN: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3443382 Abstract: In this chapter, we present tokenization of equity crowdfunding on a Blockchain as a possible approach to ease access to capital for startups. We propose a categorization of token standards into UTXO-based, layer-based and smart contract-based tokens. In a s...

In this article, we introduce a formal classification framework, in an attempt to untangle the various meanings of the term fork. We show that Blockchain forks can be processor protocol-based and emerge unintentionally or deliberately. We then proceed with a sub-classification of protocol-based forks and analyze their persistency. We further show h...

This paper explores the Decentralized Finance (DeFi) ecosystem. We examine how DeFi is emerging on top of the public Ethereum smart contract platform, compare it to the centralized architecture of traditional financial markets and highlight opportunities and potential risks of this ecosystem. We propose a multi-layered framework to analyze the impl...

As blockchain technology is maturing to be confidently used in practice, its applications are becoming evident and, correspondingly, more blockchain research is being published, also extending to more domains than before. To date, scientific research in the field has predominantly focused on subject areas such as finance, computer science, and engi...

Article
The term decentralized finance (DeFi) refers to an alternative financial infrastructure built on top of the Ethereum blockchain. DeFi uses smart contracts to create protocols that replicate existing financial services in a more open, interoperable, and transparent way. This article highlights opportunities and potential risks of the DeFi ecosystem....
Chapter
In this chapter, we present tokenization of equity crowdfunding on a Blockchain as a possible approach to ease access to capital for startups. We propose a categorization of token standards into UTXO-based, layer-based and smart contract-based tokens. In a second step, we analyze the advantages that tokenization can bring, such as cryptographically...
Article
We analyze locational preferences of investors in the metaverse. The setting allows us to compile a unique data set with parcel- and investor-specific observations. We find strong evidence that location matters even in a virtual world with negligible transportation costs. Locational preferences come in two distinct forms. Investors are willing to p...

In this paper, we analyze various Decentralized Finance (DeFi) protocols in terms of their token distributions. We propose an iterative mapping process that allows us to split aggregate token holdings from custodial and escrow contracts and assign them to their economic beneficiaries. This method accounts for liquidity-, lending-, and staking-pools...
Book
An introduction to cryptocurrencies and blockchain technology; a guide for practitioners and students. Bitcoin and blockchain enable the ownership of virtual property without the need for a central authority. Additionally, Bitcoin and other cryptocurrencies make up an entirely new class of assets that have the potential for fundamental change in t...

In this paper, we propose an autonomous vending machine that is governed by a public Blockchain and smart contracts platform. Set up as a decentralized autonomous organization, it serves as an open marketplace for physical goods, where anyone can buy and/or sell objects. We propose a basic architecture for the machine, analyze pricing and fee mecha...
Article
Blockchain forks can have severe economic implications, sow uncertainty and undermine trust. In this paper, we introduce a formal framework to study the emergence, persistency and economic consequences of blockchain forks. We argue that blockchain forks can be process- or protocol-based and emerge unintentionally or deliberately. We then proceed wi...

This paper provides an overview on stablecoins and introduces a novel terminology to help better identify stablecoins with truly disruptive potential. It provides a compact definition for stablecoins, identifying the unique features that make them distinct from previously known payment systems. Furthermore, it surveys the different use cases for st...

Proof-of-work cryptocurrencies are heavily criticized for the alleged inefficiency of their mining mechanism. However, critics fail to distinguish between the resources that are used to secure the blockchain and those that are wasted. In this paper, we introduce a simple mining model and use this model to analyze the consensus protocol's efficiency...

Blockchain is a very interesting and promising technology. It is, however, also a very complex and highly interdisciplinary one. The underlying concepts are a mixture of computer science, cryptography, and economics. To truly grasp the technology and its potential, one needs to have a background in all three of these disciplines. To make matters wo...

Cash is accused of three sins: First, cash is inefficient and costly to use, and society would be better off without it. Second, it promotes crime, and facilitates money laundering and tax evasion. Third, it makes negative nominal interest rates infeasible. In certain situations, this may hinder central banks from implementing optimal monetary poli...

Question (1)
Question
With COVID-19 and many countries in lockdown mode, most academic conferences got cancelled. Since these conferences are essential for early feedback, the general exchange of ideas and the formation of research collaborations, I have been thinking about alternatives. One potential alternative is the move to virtual conferences.
  • Would you be interested in purely virtual conferences? Why, why not? What are the pros and cons?
  • Does anyone have experience with virtual conferences? If yes, what platforms have been used? How was the experience?
Looking forward to the discussion.
