Abstract:
With the increase of interconnectivity and ubiquitous data access, new services have emerged. Distributed Ledger Technologies and their underlying principles can be used to reach agreement or consensus upon a distributed state in a highly distributed environment. They have many different aspects and can therefore be viewed from various angles, including the financial and economic, legal, political, and sociological perspective, as well as considering technical and socio-technical points of view. In the presentation I will show three aspects that are important in our research: (1) theoretical foundations, (2) understanding real world phenomena, and (3) impact. For instance, proof-of-work (PoW) as used in Bitcoin is not only relevant to achieving consensus but also serves as a source of randomness. Without it leader selection becomes an issue. Finally, understanding economic incentives and malicious behavior to undermine consensus in public blockchains is important to create a stable cryptocurrency environment upon which new services can be built.
