摘要: The Decentralised Web (DW) has recently seen a renewed momentum, with number of DW platforms like Mastodon, Peer-Tube, and Hubzilla gaining increasing traction. These offer alternatives to traditional social networks Twitter, YouTube, Facebook, by enabling the operation web infrastructure services without centralised ownership or control. Although their differ greatly, modern mostly rely on two key innovations: first, open source software allows anybody setup independent servers ("instances") that people can sign-up use within local community; second, they build top federation protocols so instances mesh together, in peer-to-peer fashion, globally integrated platform. In this paper, we present measurement-driven exploration these innovations, using popular microblogging platform (Mastodon) as case study. We focus identifying challenges might disrupt continuing efforts decentralise web, empirically highlight properties are creating natural pressures towards recentralisation. Finally, our measurements shed light behaviour both administrators (i.e., setting up instances) regular users who platforms, also discussing few techniques may address some issues observed.
