Since the dawn of BitTorrent technology, free-riding has always been a critical
issue restricting the performance and availability of the BitTorrent network. To solve this problem, BitTorrent involves a tit-for-tat mechanism which does not function satisfactorily against free-riding. Private trackers implement credit systems to eliminate...

Trust on the internet is largely facilitated by reputation systems on centralized online platforms. How- ever reports of data breaches and privacy issues on such platforms are getting more frequent. We argue that only a decentralized trust system can enable a privacy-driven and fair future of the online economy. This requires a scalable system...

In decentralized applications requirements on latency are high. For instance, in trading
applications a millisecond latency advantage can save companies millions of dollars. In
this thesis a design is proposed for an overlay in a decentralized peer-to-peer system
that lowers the latency between connected peers. The overlay is...

SRAM PUF has a potential to become the main player in hardware security. Unfor- tunately, currently available solutions are usually locked to specific entities, such as companies or universities. Here, we introduce the first open source project to de- velop software-based SRAM PUF technology using off-the-shelf SRAM. We also present testing...

It is a common case that resources belong to different people who are distributed across the world. So, for making good use of resources, people have to cooperate with each other. Cooperation is important not only in the physical world but also in cyberspace. Computers holding different resources also need to cooperate with others. The problems...

Blockchain systems have the potential to decentralise many traditionally centralised systems. However, scalability remains a key challenge. Without a horizontally scalable solution, where performance increases by adding more nodes to the system, blockchain systems remain unsuitable for ubiquitous use. We design a novel blockchain system called...

Throughout this project two components have been created: Cloudomate and
PlebNet. Cloudomate is a program that can purchase virtual private servers (VPS)
from a number of providers with Bitcoin, it is accessed through a command line
interface and published as Python library. PlebNet is the implementation of an
autonomous self...

The Dutch electoral voting system is designed in a way that does not fit in the current era of the digital transformation. Almost every procedure during the elections is done manually and change in policy is very difficult as it requires a change in legislation.
This thesis explores a more trustworthy, transparent and less expensive way of...
