Foundations of Blockchain Systems
One of the most successful applications of modern cryptography has been its use in electronic and digital payment systems. In traditional systems, a trusted authority handles all payments (e.g., a bank or a credit card company). More recently, blockchain systems have emerged as a trust-free and increasingly popular alternative. In a blockchain system, users jointly emulate the trusted authority by running a distributed protocol to agree on the transaction history of users (i.e., the blockchain). Making blockchain systems a secure and scalable environment poses many new and fascinating challenges that require solutions from both cryptography and distributed computing. In my talk, I will explain the different areas of my research and their importance as components that make up a blockchain system. For each of these areas, I will also list some of the open questions that I plan to work on in the near future.

Julian Loss obtained his MSc in computer science from ETH Zurich in 2016 and his Ph.D. from the Ruhr University of Bochum in 2019. He is currently a postdoc at the University of Maryland in the group of Jonathan Katz. His interests include classic cryptographic primitives such as digital signatures and multi-party computation as well as blockchain/consensus protocols.
