Asynchronous BFT Asset Transfer: Quasi-Anonymous, Light, and Consensus-Free
Timothé Albouy, Emmanuelle Anceaume, Davide Frey +4
This paper introduces a new asynchronous Byzantine-tolerant asset transfer system (cryptocurrency) with three noteworthy properties: quasi-anonymity, lightness, and consensus-freed…
Near-Optimal Communication Byzantine Reliable Broadcast under a Message Adversary
Timothé Albouy, Davide Frey, Ran Gelles +5
We address the problem of Reliable Broadcast in asynchronous message-passing systems with nodes, of which up to are malicious (faulty), in addition to a message adversary t…
Process-Commutative Distributed Objects: From Cryptocurrencies to Byzantine-Fault-Tolerant CRDTs
Davide Frey, Lucie Guillou, Michel Raynal +1
This paper explores the territory that lies between best-effort Byzantine-Fault-Tolerant Conflict-free Replicated Data Types (BFT CRDTs) and totally ordered distributed ledgers, su…
Context Adaptive Cooperation
Timothé Albouy, Davide Frey, Mathieu Gestin +2
As shown by Reliable Broadcast and Consensus, cooperation among a set of independent computing entities (sequential processes) is a central issue in distributed computing. Consider…
