I had like 100 bucks in there!\"—said Peter, who had not yet installed a version of the Taler wallet with our shiny new incremental, zero knowledge, CRDT-based, backup and sync feature the moment he felt his empty pocket.\n\nIn this talk, the guiding principles, privacy and design considerations, and technical details behind Taler’s new backup and sync protocol will be presented, along with a brief demostration of the feature if the author manages to get it working by Datenspuren '26.\n\nLicensed to the public under
