Decentralized applications, also known as dApps, are the new paradigm for writing business-critical software. Recruiting developers with appropriate qualifications and skills for this activity is key, yet challenging. The main problem is that the portfolio of developers is usually scattered across centralized platforms like GitHub and LinkedIn,...

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...

A challenging problem in decentralized systems is encouraging long-term cooperative behaviour between strangers. It is often not immediately bene_cial to cooperate without the guarantee of direct reciprocity. Cooperation among entities in the long term results in sustainability while sel_sh behaviour can lead to the collapse and distrust of such...

We explore a new stage in the evolution of digital trust, trusting strangers with your funds. We address the trust issues when giving money to others and relying on them to forward it. For fraud identification, we leverage our deployed blockchain which gradually builds trust between interacting strangers. Our blockchain fabric, called TrustChain...

Humanity’s notion of trust is shaped by new platforms operating in the emerging sharing economy, acting as intermediate matchmaker for ride sharing, housing facilities or freelance labour, effectively creating an environment where strangers trust each other. While millions of people worldwide rely on online sharing activities, such services are...

Accounting mechanisms based on credit are used in peer-to-peer systems to track the contribution of peers to the community for the purpose of deterring freeriding and rewarding good behavior. Most often, peers earn credit for uploading files, but other activities might be rewarded in the future as well, such as making useful comments or...

User interactions are indispensable for any online network to thrive, especially for BitTorrent‐like and Web real‐time communication‐based distributed online networks that rely on users' collective contributions instead of the help of central servers. User interactions provide fine‐grained information for many applications, such as security...

Distributed reputation systems establish trust among strangers in online communities and provide incentives for users to contribute. In these systems, each user monitors the interactions of others and computes the reputations accordingly. Collecting information for computing the reputations is challenging for the users due to their vulnerability...

Many private BitTorrent communities employ Sharing Ratio Enforcement<br/>(SRE) schemes to incentivize users to contribute. It has been demonstrated<br/>that users in private communities are highly dedicated and that they seed much<br/>longer than users in communities where SRE is not employed. While most pre-<br/>vious studies focus on showing...

Many peer-to-peer communities, including private BitTorrent Communities that serve hundreds of thousands of users, utilize<br/>credit-based or sharing ratio enforcement schemes to incentivize their members to contribute. In this paper, we analyze the performance<br/>of such communities from both the system-level and the user-level perspectives....

Enhancing reciprocity has been one of the primary motivations for the design of incentive policies in BitTorrent-like P2P systems. Reciprocity implies that peers need to contribute their bandwidth to other peers if they want to receive bandwidth in return. However, the over-provisioning that characterizes today’s BitTorrent communities and the...

Many private BitTorrent communities employ Sharing Ratio Enforcement (SRE) schemes to incentivize users to contribute their upload resources. It has been demonstrated that communities that use SRE are greatly oversupplied, i.e., they have much higher seeder-to-leecher ratios than communities in which SRE is not employed. The first order effect...

Centralised solutions for Video-on-Demand (VoD) services, which stream pre-recorded video content to multiple clients who start watching at the moments of their own choosing, are not scalable because of the high bandwidth requirements of the central video servers. Peer-to-peer (P2P) techniques which let the clients distribute the video content...

<br/>Peer-to-peer (p2p ) file sharing systems rely on the sharing of resources by large fractions of partic- ipants. Sharing-ratio enforcement provides a very strong incentive for peers to contribute, leading to a higher performance for all peers in the system. One way of implementing this is by banning peers that do not share enough, determined...
