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…
Dynamic Byzantine Reliable Broadcast [Technical Report]
Rachid Guerraoui, Jovan Komatovic, Petr Kuznetsov +3
Reliable broadcast is a communication primitive guaranteeing, intuitively, that all processes in a distributed system deliver the same set of messages. The reason why this primitiv…
Can 100 Machines Agree?
Rachid Guerraoui, Jad Hamza, Dragos-Adrian Seredinschi +1
Agreement protocols have been typically deployed at small scale, e.g., using three to five machines. This is because these protocols seem to suffer from a sharp performance decay.…
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 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…
SBFT: a Scalable and Decentralized Trust Infrastructure
Guy Golan Gueta, Ittai Abraham, Shelly Grossman +6
SBFT is a state of the art Byzantine fault tolerant permissioned blockchain system that addresses the challenges of scalability, decentralization and world-scale geo-replication. S…
Monotonic Prefix Consistency in Distributed Systems
Alain Girault, Gregor Gössler, Rachid Guerraoui +2
We study the issue of data consistency in distributed systems. Specifically, we consider a distributed system that replicates its data at multiple sites, which is prone to partitio…
