Project summary
The ‘Eco-sensus’ research project addresses the environmental footprint of distributed systems that apply consensus mechanisms. Prime examples of such systems are cryptocurrencies (eg., Bitcoin, Ethereum, and Filecoin) and distributed storage systems (eg., Filecoin). The goal of the project is to quantify and reduce the environmental footprint, including both the energy consumption and other environmental impacts such as the hardware lifecycle, of a selected set of systems. The overarching project goals are threefold: (1) to create models for estimating the size of the environmental footprint, (2) to provide methods for measuring this footprint, and (3) to provide mitigation methods for reducing this footprint. By modelling and measuring we will be able to demonstrate and predict the impact on our environment. This will raise awareness, inform tool development, and enable incentives to actually deploy our mitigation methods for reducing the footprint. Our research helps to address important societal challenges like global warming, climate change, and spare use of scarce sources. We intend to publish scientific papers on our modelling and measurement efforts, to create online dashboards, and to promote our mitigating controls for integration and application in distributed systems.
We envision how current developments that address the environmental footprint of distributed systems with consensus algorithms will evolve in the coming years, and aim at getting well ahead of these developments. We intend to do so partly by participating in ongoing innovative projects, and partly by exploring completely new directions.
In the context of the project, we invite applications for a fully financed postdoc research position with a background and focus on computing science and a strong affinity with environmental science.
Your tasks are:
You will be the prime researcher in the ‘Eco-sensus project’ and will work in close collaboration with dr. Harald Vranken (associate professor at Open Universiteit and Radboud University in the Netherlands, expert on security and energy analysis of consensus algorithms) and dr. Alan Ransil (research scientist at Protocol Labs in the USA, expert on distributed systems and the decentralized web). The research team may be extended with master students doing their graduation projects.
Fixed-term contract: for a period of 2 years (with intermediate evaluation after 1 year). We are open to discuss secondment or other arrangements.
The salary will be determined on the basis of your experience and qualifications, but will be in accordance with the general salary scales 10-12 of the CAO-NU. An indication of the maximum gross salary is € 5.943.- per month, for a full-time appointment.
The OU provides good secondary benefits such as training, mobility, hybrid work, part-time employment and paid parental leave.
Flexible studying anywhere in the Netherlands and (Belgium) Flanders
The Open Universiteit (OU) is the part-time university in the Netherlands. Students follow personalised and activating academic distance education and disciplinary research is carried out within the various fields of science. Students can complete bachelor and master programmes in seven fields of study. The characteristics of education are openness, flexibility and quality (see www.ou.nl/rankings). Much attention is paid to improving the study success of students. The OU has over 18,000 students and more than 700 employees. The OU has branches in the Netherlands and Belgium (see www.ou.nl/studiecentra). The main office is located in Heerlen.
The latest technologies and educational insights are applied both in the bachelor's and master's programmes and courses and in projects and programmes with partners. Nationally and internationally, the OU plays an important role in the innovation of higher education. Education is interwoven with research, which also ensures that the current state of science is incorporated. The OU invests not only in disciplinary research in eight scientific fields, but also in research in a multidisciplinary programme: Innovating for resilience.
The faculty of Science is one of the six faculties of the OU of the Netherlands. Education, research and valorisation are the main tasks. The faculty offers academic bachelor and master programmes in the fields of Computer Science, Information Science, Environmental Sciences, and an Artificial Intelligence master programme is currently under development. The faculty’s research programme focuses on Innovating for Resilience. Further, the faculty is partner in the Center for Actionable Research of the OU (CAROU). The faculty has Ph.D.-students who conduct research on various current topics within the research programme. By focusing on research that is interwoven with education, as well as the close link with practice, work at our faculty provides many innovative and challenging opportunities for entrepreneurial researchers.’
Department of Computer Science
The Department of Computer Science is an enthusiastic and ambitious group of approximately 35 people (29 fte) focussing on artificial intelligence, educational and learning technology, software quality, and security and privacy issues. The group contributes to these challenges through excellent research and online teaching programmes, covering a large diversity of topics, e.g. deep learning applications in industry, intelligent tutoring systems, privacy-aware technologies, reinforcement learning, e-health applications, Bayesian networks, cyber-security, automated software testing, multi-agent systems, logics for AI, and responsible AI. The department’s research lines are presented in the research strategy “Towards high quality and intelligent software” for 2020-2025. The online academic educational programmes of this Department have received the highest accolades in the country in this domain for years.
