Byzantine-Resilient Learning Beyond Gradients: Distributing Evolutionary Search
Andrei Kucharavy, Matteo Monti, Rachid Guerraoui +1
Modern machine learning (ML) models are capable of impressive performances. However, their prowess is not due only to the improvements in their architecture and training algorithms…
Chop Chop: Byzantine Atomic Broadcast to the Network Limit
Martina Camaioni, Rachid Guerraoui, Matteo Monti +3
At the heart of state machine replication, the celebrated technique enabling decentralized and secure universal computation, lies Atomic Broadcast, a fundamental communication prim…
Oracular Byzantine Reliable Broadcast [Extended Version]
Martina Camaioni, Rachid Guerraoui, Matteo Monti +1
Byzantine Reliable Broadcast (BRB) is a fundamental distributed computing primitive, with applications ranging from notifications to asynchronous payment systems. Motivated by prac…
Carbon: Scaling Trusted Payments with Untrusted Machines
Martina Camaioni, Rachid Guerraoui, Jovan Komatovic +4
This paper introduces Carbon, a high-throughput system enabling asynchronous (safe) and consensus-free (efficient) payments and votes within a dynamic set of clients. Carbon is ope…
Online Payments by Merely Broadcasting Messages (Extended Version)
Daniel Collins, Rachid Guerraoui, Jovan Komatovic +7
We address the problem of online payments, where users can transfer funds among themselves. We introduce Astro, a system solving this problem efficiently in a decentralized, determ…
Scalable Byzantine Reliable Broadcast (Extended Version)
Rachid Guerraoui, Petr Kuznetsov, Matteo Monti +3
Byzantine reliable broadcast is a powerful primitive that allows a set of processes to agree on a message from a designated sender, even if some processes (including the sender) ar…
The Consensus Number of a Cryptocurrency (Extended Version)
Rachid Guerraoui, Petr Kuznetsov, Matteo Monti +2
Many blockchain-based algorithms, such as Bitcoin, implement a decentralized asset transfer system, often referred to as a cryptocurrency. As stated in the original paper by Nakamo…
AT2: Asynchronous Trustworthy Transfers
Rachid Guerraoui, Petr Kuznetsov, Matteo Monti +2
Many blockchain-based protocols, such as Bitcoin, implement a decentralized asset transfer (or exchange) system. As clearly stated in the original paper by Nakamoto, the crux of th…
