Daniel Kraft studied mathematics and physics at the University of Graz, Austria, where he obtained two Master’s degrees in Applied Mathematics and Theoretical Physics. He then wrote his PhD thesis about shape optimisation with the level-set method, and obtained his degree with distinction in the IGDK 1754 doctoral program (collaboration between the University of Graz and the Technical University of Munich). Daniel has published eight scientific papers in peer-reviewed journals so far in various fields, from geometric measure theory to blockchain technology. He has been involved in cryptocurrency development since 2013, and has been the lead blockchain developer for the revolutionary Namecoin and Huntercoin projects since 2014. He has also contributed to free software from Firefox, GCC and GNU Octave to Bitcoin Core. After leaving his senior developer role at Google Zurich to work full time on the XAYA project, Daniel wishes to further develop and innovate in blockchain technology.
