Blockchains & Distributed Ledger TechnologySpeaker: Edgar Weippl – Vienna, Austria
Topic(s): Security and Privacy
While in this context scalability and sustainability are topics of active research and development, other aspects have received considerably less attention and many open questions remain regarding the long-term perspective of both permissionless and permissioned blockchain technologies.
* Privacy and (selective) transparency
* Socio-economic factors and game theory
* Immutability and updateability/migration strategies
* Alternative Applications, such as Smart Contracts, Transparency and integrity of (business) processes (e.g., supply-chain management, ...), Identity management, (Digital) rights management
Examples for research questions that we will discuss:
* What are the impacts of changing incentives on the development of blockchain technology in general and of cryptocurrencies in particular? For instance, the reduction of mining rewards to zero will make transaction fees more important for miners. Will users still use blockchains with increased transaction fees, will miners mine with lower or even without mining rewards? How can we simulate long-term effects?
* Who will control the future development of blockchain technology? Will users, miners, or developers be in charge? We have seen hard forks in Ethereum forced by developers, but we also see voting mechanisms that include miners. The financial success of a cryptocurrency however -- and, thus, the underlying incentive systems for reaching consensus -- is in the hands of the end users.
