Consensus, state-machine replication (SMR) and total order broadcast (TOB) protocols are notorious for being poorly scalable with the number of participating nodes. Despite the rec…
BMS: Secure Decentralized Reconfiguration for Blockchain and BFT Systems
Selma Steinhoff, Chrysoula Stathakopoulou, Matej Pavlovic +1
Reconfiguration of long-lived blockchain and Byzantine fault-tolerant (BFT) systems poses fundamental security challenges. In case of state-of-the-art Proof-of-Stake (PoS) blockcha…
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…
