Web3 Sybil avoidance using network latency

Web3 is emerging as the new Internet-interaction model that facilitates direct collaboration between strangers without a need for prior trust between network participants and without central authorities. However, one of its shortcomings is the lack of a defense mechanism against the ability of a single user to generate a surplus of identities,...

Reputation-Based Data Carrying for Web3 Networks

Web3 networks are emerging to replace centrally-governed networking infrastructure. The integrity of the shared public infrastructure of Web3 networks is guaranteed through data sharing between nodes. However, due to the unstructured and highly partitioned nature of Web3 networks, data sharing between nodes in different partitions is a...

Foundations of Peer-to-Peer Reputation

Successful classification of good or bad behavior in the digital domain is limited to central governance, as can be seen with trading platforms, search engines and news feeds. We explore and consolidate existing work on decentralized reputation systems to form a common denominator for what makes a reputation system successful when applied...

Deployment of a Blockchain-Based Self-Sovereign Identity

Digital identity is unsolved: after many years of research there is still no trusted communication over the Internet. To provide identity within the context of mutual distrust, this paper presents a blockchain-based digital identity solution. Without depending upon a single trusted third party, the proposed solution achieves passport-level...

Multi-core architecture for anonymous Internet streaming

There are two key components for high throughput distributed anonymizing applications. The first key component is overhead due to message complexity of the utilized algorithms. The second key component is an nonscalable architecture to deal with this high throughput. These issues are compounded by the need for anonymization. Using a state of the...

Closing the gap between the Web and Peer to Peer

During the course of Q4 of the 2012-2013 academic year, we have worked on the project of a Peer-to-Peer web browser. After a two week orientation phase, a six week programming phase and nally another two week reporting phase we deliver our product. The final result of this endeavor is an integrated web browser in the Tribler platform, which...
