A cutting-edge reconciliation algorithm developed at WIDE is being used by Bluesky, the decentralized social network built on the AT protocol. In a recent research paper detailing Bluesky’s tech stack [1], researchers from Cambridge and Bluesky reveal that the AT protocol harnesses Merkle Search Trees (MST) – an innovative data…

Et si pour voyager dans l’inconnu, il suffisait de faire de la recherche ? Manon Sourisseau, François Taïani, Timothé Albouy, et Davide Frey (de WIDE) ainsi qu’Emmanuelle Anceaume (de l’équipe PIRAT) on participé au tournage de l’émission Esprit Sorcier TV : les surprises de la recherche filmée à Rennes en…
Congratulations to Dimitri Lereverend, Davide Frey, and François Taiani for their work “Low-Cost Privacy-Preserving Decentralized Learning” accepted at PoPETS 2025. The paper explores the use of correlated noise in decentralized learning to achieve an efficient privacy-utility tradeoff. Decentralized learning allows machine learning while keeping individual data local and private, but…
WIDE is organizing a one-day workshop on Reliable Distributed Systems and Blockchain on December 17, 2024, in Rennes. International experts will give invited talks, showcasing key recent results on distributed systems and blockchain research. More information is available here.
Congratulations to Augustin Godinot, Erwan Le Merrer, and Francois Taiani for their paper entitled “Queries, Representation & Detection: the next 100 model fingerprinting schemes” accepted at AAAI 2025, a flagship conference in artificial intelligence. Comparing learned models is a fundamental task in Machine Learning (ML). In this paper, they studied model…
Congratulations to Brice Ekane, Djob Mvondo, and Yérom-David Bromberg for their paper entitled “DiSC: Backpressure Mitigation In Multi-tier Applications With Distributed Shared Connection” accepted at NSDI 2025, a flagship conference in network and systems. This work targets load reduction on frontend servers by intelligently displacing the load on backend servers…
George Giakkoupis and Dimitrios Los from the WIDE team, jointly with Marcos Kiwi (Universidad de Chile), had their paper entitled “Naively Sorting Evolving Data is Optimal and Robust” accepted at FOCS 2024, one of the leading conferences in computer science! In this paper, the authors study sorting in the evolving…
Two papers from the WIDE team have been accepted for presentation at ACM Middleware 2024. The first paper concerns predicting the effects of a system-level patch on applications running inside virtual machines in the Cloud. The work entitled “𝑈𝑇𝑤𝑖𝑛𝑉𝑀: Reliable hints on the effects of hypervisor updates on VMs in…
Congratulations to Remy Raes for his paper accepted at DAIS 2024. The paper introduces a novel framework, FIL, that allows the storage of large amounts of sensor data in constrained devices while controlling the modelling error. FIL was evaluated on real world datasets on mainstream smartphones, which shows its importance…
