Massive collaborative editing becomes a reality through leading projects such as the Wikipedia. Such massive collaboration is currently supported with costly central service. To avoid such costs, we aim to provide a peer-to-peer collaborative editing system. Existing approaches that propose distributed collaborative distributed either do not scale in term of users number or in term of editions number. We present the Logoot approach that scales in these both dimensions while ensuring causality, consistency and intention criteria. We evaluate the Logoot approach and compare it to others with a corpus of all the editions applied on a set of the most edited and biggest page of the Wikipedia.
