Toward a Trustworthy Decentralized Web

蒂姆·伯纳斯-李呼吁重新去中心化网络，以及随后举行的2016年去中心化网络峰会，将挑战全球的研究人员，提出能够为网络带来开放性和弹性的机制和架构。******要使这样的愿景成为现实，最终用户必须积极参与数据和应用程序共享和托管工作。这就提出了几个问题，例如：***——需要为参与工作的用户提供激励；***——需要确定值得信赖的参与者并抵御来自恶意同伴的攻击；***——需要应用程序是实用的、计算有效的和可扩展的。******我们建议以我们在点对点数据共享架构和应用方面的工作为基础来研究上述问题。特别是，我们将研究一种基于点对点文件共享网络之上的社交网络覆盖的架构，为此我们将：***-评估数据和知识查询效率，***-提出用户参与的激励方案，***-并研究他们为效率和信任目的而自组织的方式。******我们将通过分析方法、模拟和实际应用的实际部署来验证我们的工作。

Tim Berners-Lee's call to re-decentralize the web, and the 2016 Decentralized Web Summit that followed, will challenge researchers worldwide to come up with mechanisms and architectures that bring openness and resiliency to the web. ******For such a vision to become reality, end users will have to participate actively in the data- and application-sharing and hosting effort. This raises several issues, such as: ***- the need to provide an incentive to users to participate in the effort, ***- the need to determine trustworthy participants and to resist attacks from malicious peers, ***- the need for the applications to be practical, computationally effective, and scalable.******We propose to build on our work on peer-to-peer data-sharing architectures and applications to study the above issues. In particular, we will investigate an architecture based on an overlay of a social network on top of a peer-to-peer file-sharing network, for which we will: ***- evaluate data and knowledge query efficiency, ***- propose incentive schemes for the participation of users, ***- and study the way they will self-organize for efficiency and trust purposes. ******We will validate our work with analytical methods, simulations and real-life deployment of practical and useful applications.
