Delft University of Technology invites applicants for a PhD position in 
the Distributed Systems Group in the Department Software Technology of 
the Faculty of Electrical Engineering, Mathematics and Computer Science.

*Job Description*

Consensus is a key component of Blockchains that is either implemented 
using a proof-of-X mechanism or using Byzantine fault tolerant state 
machine replication (BFT-SMR). One of the major steppingstones for a 
wide adoption of fault and intrusion tolerance techniques is their 
performance and modularity.  It has been recently shown that some of the 
transactions a Blockchain system processes do not have to be implemented 
using consensus, and can rely on lighter mechanisms.

The key tasks of this project are: (i) leveraging recent lightweight 
mechanisms to automatically process the transactions they can be applied 
on; (ii) defining the abstractions that will allow the modular 
composition of BFT-SMR or Blockchain systems; (iv) opening the 
membership of BFT-SMR protocols to securely use them in permissionless 
Blockchain systems.

*The Distributed Systems Group*

The Distributed Systems group (, under the 
leadership of Prof. Dick Epema, performs world-class research in the 
design, implementation, deployment, and analysis of large-scale, 
Internet-based computer systems. It currently has two research lines: 
distributed machine-learning systems (e.g., federated learning and 
performance optimization) and cooperative systems (blockchain 
technology, trust and reputation systems). Its research is fundamental, 
aimed at the development and evaluation of new generic concepts in 
systems software, and application-driven, motivated by important 
application areas. Much of it is experimental, validating the proposed 
new concepts by means of implementation and deployment in prototypes 
that are used in the real world.

*TU Delft (Delft University of Technology)*

Delft University of Technology is built on strong foundations. As 
creators of the world-famous Dutch waterworks and pioneers in biotech, 
TU Delft is a top international university combining science, 
engineering and design. It delivers world class results in education, 
research and innovation to address challenges in the areas of energy, 
climate, mobility, health and digital society. For generations, our 
engineers have proven to be entrepreneurial problem-solvers, both in 
business and in a social context. At TU Delft we embrace diversity and 
aim to be as inclusive as possible (see our Code of Conduct 
Together, we imagine, invent and create solutions using technology to 
have a positive impact on a global scale. Challenge. Change. Impact!

*Faculty Electrical Engineering, Mathematics and Computer Science*

The Faculty of Electrical Engineering, Mathematics and Computer Science 
(EEMCS) brings together three disciplines - electrical engineering, 
mathematics and computer science. Combined, they reinforce each other 
and are the driving force behind the technology we use in our daily 
lives. Technology such as the electricity grid, which our faculty is 
helping to make future-proof. We are also working on a world in which 
humans and computers reinforce each other. We are mapping out disease 
processes using single cell data, and using mathematics to simulate 
gigantic ash plumes after a volcanic eruption. There is plenty of room 
here for ground-breaking research. We educate innovative engineers and 
have excellent labs and facilities that underline our strong 
international position. In total, more than 1,100 employees and 4,000 
students work and study in this innovative environment.
