Abstract : Collaborative editors allow users to distribute the writing of a document across space and time. Thanks to their ease of use, real-time collaborative editors working in Web browsers vastly contributed to the adoption of such tools. However, current editors are centralized: a service provider's server hosts an editing session. It raises privacy and scalability issues. Recently, the enabling of browser-to-browser connection establishments opened new opportunities in favor of a decentralized Web. Decentralized real-time collaborative editors working in Web browsers must efficiently handle highly dynamic groups of different size. Contributions of this thesis are threefold: (i) To represent the document, we propose a replicated data structure for sequences using metadata the size of which scales sub-linearly compared to the number of inserted characters. (ii) To efficiently propagate the changes to all editors involved in the collaborative writing, we propose a random peer sampling protocol that supports Web browsers constraints and self-adjusts its functioning to the variations of network membership. (iii) To demonstrate the feasibility of a decentralized real-time collaborative editors running in Web browsers, we propose an editor using (i) and (ii), and we highlight its scalability.
