Helmut Dietl Explains the Mechanisms of Stablecoins

Stablecoins are cryptocurrencies that are tied to a reference value (typically the USD). They have been developed to cope with the high volatility in crypto markets. Prof. Helmut Dietl shows different designs and the underlying mechanisms of stablecoins in his cash column.

News report

Claudio Tessone about speculation and privacy in NFT markets

Daniel Saraga has written an interesting article on how NFTs disrupted the art market in less than a year. He explains how NFTs work and shows the enormous hype about NFTs and the speculation involved. Prof. Claudio Tessone, the chairman of the UZH Blockchain Center, points out that the design of current blockchains (e.g., constant rate of supply) fuels this speculation. Furthermore, it is a myth to think that blockchain transaction are private. As Claudio Tessone points out, everything on a blockchain network is transparent and even though users are pseudonymous, one can with the help of mathematical network techniques unravel user’s pattern.

Liudmila Zavolokina’s Insights on Trust in Blockchains

Can we trust a trust-less technology? Dr. Liudimila Zavolokina, a member of
the UZH Blockchain Center, raises this question in an article in inside-it
(German). Her research shows that – despite the wide misconception that
blockchain does not require any trust anymore – trust still needs to be built
up. Trust in blockchains is influenced by three factors: understandability,
responsibility and reputation, and data quality. To better understand how these
factors determine trust in blockchains, read the article here:

Rolf H. Weber Publishes an Article on the Liability Issue in Blockchain Transactions

Who is liable in blockchain transactions? Prof. Dr. iur. Rolf H. Weber tackles this intricate topic in an article published in German language in Schweizerische Juristen-Zeitung (2021, pp. 679-687). The liability discussion centers around two actors: operators of digital security registers and providers of trading platforms based on digital ledger technologies. Rolf H. Weber argues that it is crucial for the liability discussion to differentiate among different layers, e.g., settlement, asset, protocol, application, and aggregation layer. These layers can be allocated to the different actors allowing for a clear liability attribution. In practice, the two most important liability cases originate from coding errors and/or false information. For further discussion, please contact

Christian Ewerhart on the Future of Blockchains

Are cryptocurrencies and blockchains revolutionary or overhyped? Prof. Dr. Christian Ewerhart from the University of Zurich gives an answer to this question in several Swiss newspapers. According to Prof. Ewerhart, it is too early to make a clear judgement, since the development is still in an infant stage. However, there is an immense amount of innovation taking place in the field. To understand why Prof. Ewerhart thinks that the comparison between blockchains and the internet is not adequate, read the full articles below:
