Research

In my Ph.D. thesis, I am focusing on public blockchains. In this research, I aim to solve two issues of public blockchains, namely the ever-growing size and the impossibility to correct data in the blockchain, based on a majority decision. Besides, I am involved in many projects implemented at the Secure Information Technology Center Austria (A-SIT). Some example projects are:
