QScale: Probabilistic Chained Consensus for Moderate-Scale Systems
Hasan Heydari, Alysson Bessani, Kartik Nayak
Existing distributed ledger protocols either incur a high communication complexity and are thus suited to systems with a small number of processes (e.g., PBFT), or rely on committe…
Chasing the Speed of Light: Low-Latency Planetary-Scale Adaptive Byzantine Consensus
Christian Berger, LÃvio Rodrigues, Hans P. Reiser +2
Blockchain technology sparked renewed interest in planetary-scale Byzantine fault-tolerant (BFT) state machine replication (SMR). While recent works predominantly focused on improv…
Knowledge Connectivity Requirements for Solving BFT Consensus with Unknown Participants and Fault Threshold (Extended Version)
Hasan Heydari, Robin Vassantlal, Alysson Bessani
Consensus stands as a fundamental building block for constructing reliable and fault-tolerant distributed services. The increasing demand for high-performance and scalable blockcha…
Probabilistic Byzantine Fault Tolerance (Extended Version)
Diogo Avelãs, Hasan Heydari, Eduardo Alchieri +2
Consensus is a fundamental building block for constructing reliable and fault-tolerant distributed services. Many Byzantine fault-tolerant consensus protocols designed for partiall…
