The introduction of Blockchain technology has led to the idea of Decentralized Autonomous Organizations.<br/>(DAOs). DAOs enable decentralized and transparent collective wealth, allowing groups of individuals to pool their funds for collective management. DAOs rely on complex smart contracts to function. Despite Bitcoin being the most popular...

Web3Recommend is a decentralized Social Recommender System implementation that enables Web3 Platforms on Android to generate recommendations that balance trust and relevance. Generating recommendations in decentralized networks is a non-trivial problem because these networks lack a global perspective due to the absence of a central authority....

Blockchain technology has allowed for the emergence of a new type of organization, the Decentralized Autonomous Organization (DAO). They have gained significant traction in recent years, reaching market capitalizations of up to 60 billion USD in 2021. These organizations coordinate economic activity by an unbounded group of people within an...

Federated learning is a privacy-enforcing machine learning technology but suffers from limited scalability. This limitation mostly originates from the internet connection and memory capacity of the central parameter server, and the complexity of the model aggregation function. Decentralized learning has recently been emerging as a promising...

The European Commission is developing a European Digital Identity (EDI), which will enable a trustworthy digital proof of identity for its citizens. We present a proof of identity in combination with cryptographic evidence of the natural person being authorized to act on behalf of a legal entity. Our study achieves this by connecting users of...

Recent years have seen an increasing interest in stablecoins from major corporate and governmental parties. The European Central Bank is investigating the possibility of introducing its own Central Bank Digital Currency. The desired features of such a currency are under discussion. One such feature is offline spending: the ability to use the...

Ranking algorithms in traditional search engines are powered by enormous training data sets that are meticulously engineered and curated by a centralized entity. Decentralized peer-to-peer (p2p) networks such as torrenting applications and Web3 protocols deliberately eschew centralized databases and computational architectures when designing...

The European Union is on course for introducing a European Digital Identity that will be available to all EU citizens and businesses. This will have a huge impact on how citizens and businesses interact online. Big Tech companies currently dictate how digital identities are used. As a result they have amassed huge amounts of private user data....

Automatically deriving 3D representations of buildings is a challenging problem which is at the base of a wide range of applications. The DE-RISC project aims to generate a 3D model of the entire city of Rotterdam in The Netherlands, enabling many of these applications. Generating a 3D model of a building can be done in a variety of ways, of...

A movement for a more transparent and decentralized Internet is globally attracting more attention. People are becoming more privacy-aware of their online identities and data. The Internet is constantly evolving. Web2 focused on companies that provide services in exchange for personal user data. Web3 commits to user-centricity using...

CRDTs are data structures that allow conflict free replication and modification. In theory, CRDTs seem like a natural fit for open P2P networks, however there are obstacles to overcome. Firstly, many proposed CRDTs are grow-only because (i) CRDTs may track deletions in permanent tombstone values or (ii) they may gather permanent information on...

This research has been performed in pursuit of the MSc Computer Science at Delft University of Technology in collaboration with the Dutch National Office for Identity Data (RvIG), part of the Dutch Ministry of the Interior and Kingdom Relations. Self-Sovereign Identity (SSI) is a relatively new concept part of a movement aspiring to create a...

After the release of Bitcoin in 2008 many advances have been made in the crypto space. The feature-set, scalability, transaction cost, and efficiency have all improved. Yet, as the development continued, the goal of Bitcoin or any other cryptocurrency as a digital payment form started to take a backseat to their utility as a store of value and...

Federated learning (FL) is a type of machine learning where devices locally train a model on their private data.<br/>The devices iteratively communicate this model to a central server which combines the models and sends the updated model back to all devices.<br/>Because the data stays on the devices and only the model is transmitted, federated...

Digital identity management has been established in a mainly centralized manner. In response to a lack of control in current identity management systems, the concept of Self-Sovereign Identity (SSI) was defined to enable decentralization. Recently, this concept gained traction, and several implementations have been proposed. The decentralized...

During the last decades of explosive growth in economic value on the Internet, we observe the trend of platformization: a shift of economic activity from happening on a wide range of companies to a few major platforms run by Big Tech corporations. This trend is highly susceptible to the rise of monopolies and oligarchs, as...

The Internet was created with the idea that any two computers connected to the shared network should be able to communicate with each other. It has also been built on the principles of decentralization, without any central entity having the power to take the network down. Yet, 50 years later, we live in a world where most of the services are...

Self-Sovereign Identity (SSI) is a new paradigm in digital identity systems that puts the end-user in control: no other actor manages, permits or revokes their digital existence. TrustChain is an academic peer-to-peer networking stack supporting SSI. It delivers passport-grade assurance by integrating with Dutch government....

The development of blockchain, along with the creation of Bitcoin, opened the road to the first digital currency that is secure against double-spending without the need for a trusted authority or centralized server. The architecture of traditional blockchain structures like the one used in Bitcoin is, however, not very scalable because of its...

Since the dawn of BitTorrent technology, free-riding has always been a critical<br/>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...
