在线社交网络，如Facebook和twitter，是当今世界一个日益增长的平台，各种平台为个人提供了通过消息和聊天以及分享视频和照片等内容进行协作的能力。这些平台中的大多数都基于集中式计算系统，这意味着系统的控制和管理掌握在一个提供者手中，必须信任它能安全地处理数据和通信跟踪。虽然用户的目标是隐私和数据主权，但供应商的目标往往是将他们存储的数据货币化。即使是私人运营的联合社交网络，也需要一些为社区服务的热心人士，通过他们可以访问自己管理的数据。点对点(P2P)技术作为一种零信任的替代方案，保证了网络的自组织和设计安全，其中最终的数据主权在于相应的用户。这些网络支持端到端通信、不妥协的访问控制、匿名性和对审查的弹性，以及由于滥用信任而导致的大量数据泄漏。这项调查的目标有三方面。首先，该调查阐述了基于p2p的在线社交网络的特性，定义了对此类(零信任)平台的需求。其次，它详细阐述了P2P框架的构建模块，这些模块允许创建复杂和高要求的应用程序，如用户/身份管理、可靠的数据存储、安全通信、访问控制和通用扩展，这些功能在其他P2P调查中没有涉及。作为第三点，本文概述了所提出的基于p2p的在线社交网络应用程序、框架和体系结构。具体来说，它探讨了可用解决方案的技术细节、相互依赖性和成熟度。
原文题目：Peer-to-Peer based Social Networks: A Comprehensive Survey
原文：Online social networks, such as Facebook and twitter, are a growing phenomenon in today’s world, with various platforms providing capabilities for individuals to collaborate through messaging and chatting as well as sharing of content such as videos and photos. Most, if not all, of these platforms are based on centralized computing systems, meaning that the control and management of the systems lies in the hand of one provider, which must be trusted to treat the data and communication traces securely. While users aim for privacy and data sovereignty, often the providers aim to monetize the data they store. Even, federated privately run social networks require a few enthusiasts that serve the community and have, through that, access to the data they manage. As a zero-trust alternative, peer-to-peer (P2P) technologies promise networks that are self organizing and secure-by-design, in which the final data sovereignty lies at the corresponding user. Such networks support end- to-end communication, uncompromising access control, anonymity and resilience against censorship and massive data leaks through misused trust. The goals of this survey are three-fold. Firstly, the survey elaborates the properties of P2P-based online social networks and defines the requirements for such (zero-trust) platforms. Secondly, it elaborates on the building blocks for P2P frameworks that allow the creation of such sophisticated and demanding applications, such as user/identity management, reliable data storage, secure communication, access control and general-purpose extensibility, features that are not addressed in other P2P surveys. As a third point, it gives an overview of proposed P2P-based online social network applications, frameworks and architectures. In specific, it explores the technical details, inter-dependencies and maturity of the available solutions.
