Unified Privacy Guarantees for Decentralized Learning via Matrix Factorization
Aurélien Bellet, Edwige Cyffers, Davide Frey +3
Decentralized Learning (DL) enables users to collaboratively train models without sharing raw data by iteratively averaging local updates with neighbors in a network graph. This se…
Asynchronous Byzantine Reliable Broadcast With a Message Adversary
Timothé Albouy, Davide Frey, Michel Raynal +1
This paper considers the problem of reliable broadcast in asynchronous authenticated systems, in which n processes communicate using signed messages and up to t processes may behav…
The Graph Neural Networking Challenge: A Worldwide Competition for Education in AI/ML for Networks
José Suárez-Varela, Miquel Ferriol-Galmés, Albert López +21
During the last decade, Machine Learning (ML) has increasingly become a hot topic in the field of Computer Networks and is expected to be gradually adopted for a plethora of contro…
: A Rock-Solid Foundation for Epidemic Consensus Algorithms in Very Large, Very Open Networks
Alex Auvolat, Yérom-David Bromberg, Davide Frey +1
Recent works have proposed new Byzantine consensus algorithms for blockchains based on epidemics, a design which enables highly scalable performance at a low cost. These methods ho…
Money Transfer Made Simple: a Specification, a Generic Algorithm, and its Proof
Alex Auvolat, Davide Frey, Michel Raynal +1
It has recently been shown that, contrarily to a common belief, money transfer in the presence of faulty (Byzantine) processes does not require strong agreement such as consensus.…
FLeet: Online Federated Learning via Staleness Awareness and Performance Prediction
Georgios Damaskinos, Rachid Guerraoui, Anne-Marie Kermarrec +3
Federated Learning (FL) is very appealing for its privacy benefits: essentially, a global model is trained with updates computed on mobile devices while keeping the data of users l…
DiagNet: towards a generic, Internet-scale root cause analysis solution
Loïck Bonniot, Christoph Neumann, François Taïani
Diagnosing problems in Internet-scale services remains particularly difficult and costly for both content providers and ISPs. Because the Internet is decentralized, the cause of su…
PnyxDB: a Lightweight Leaderless Democratic Byzantine Fault Tolerant Replicated Datastore
Loïck Bonniot, Christoph Neumann, François Taïani
Byzantine-Fault-Tolerant (BFT) systems are rapidly emerging as a viable technology for production-grade systems, notably in closed consortia deployments for nancial and supply-chai…
Dietcoin: shortcutting the Bitcoin verification process for your smartphone
Davide Frey, Marc X. Makkes, Pierre-Louis Roman +2
Blockchains have a storage scalability issue. Their size is not bounded and they grow indefinitely as time passes. As of August 2017, the Bitcoin blockchain is about 120 GiB big wh…
Vertex Coloring with Communication and Local Memory Constraints in Synchronous Broadcast Networks
Hicham Lakhlef, Michel Raynal, François Taïani
The vertex coloring problem has received a lot of attention in the context of synchronous round-based systems where, at each round, a process can send a message to all its neighbor…
