Not All Reads Are Conflicts: A Write-Only Analysis of the Sui Blockchain
Haygen Tsoi, Alberto Sonnino, Philipp Jovanovic
The paper introduces a write‑set‑only conflict analysis for the Sui blockchain that captures only real write‑serialization dependencies, providing a lower bound on contention and s…
Orcaella: Hybrid Fault Tolerance with Client-Selectable Finality Latency
Lefteris Kokoris-Kogias, Alberto Sonnino
Classical partially synchronous state machine replication, as in PBFT, tolerates f Byzantine replicas among n at least 3f+1 using three communication steps per request. Recent prot…
BlueBottle: Fast and Robust Blockchains through Subsystem Specialization
Preston Vander Vos, Alberto Sonnino, Giorgos Tsimos +2
Blockchain consensus faces a trilemma of security, latency, and decentralization. High-throughput systems often require a reduction in decentralization or robustness against strong…
Remora: Scale-out Deterministic Execution for Smart Contracts
Zhengqing Liu, Alberto Sonnino, Igor Zablotchi +2
Modern blockchains rely on a modular architecture that decouples consensus from execution. Recent advances in consensus algorithms have shifted the bottleneck to the execution laye…
Beluga: Block Synchronization for BFT Consensus Protocols
Tasos Kichidis, Lefteris Kokoris-Kogias, Arun Koshy +4
Modern high-throughput BFT consensus protocols use streamlined push-pull mechanisms to disseminate blocks and keep happy-path performance optimal. Yet state-of-the-art designs lack…
Finding Nemo-Nemo: CFT DAG-based Consensus in the WAN
Rithwik Kerur, Pasindu Tennage, Philipp Jovanovic +3
This paper introduces Nemo-Nemo, a practical crash-fault tolerant (CFT) consensus protocol designed to outperform existing protocols in wide-area networks by bridging design princi…
