Vivisecting the Dissection: On the Role of Trusted Components in BFT Protocols
Alysson Bessani, Miguel Correia, Tobias Distler +3
A recent paper by Gupta et al. (EuroSys'23) challenged the usefulness of trusted component (TC) based Byzantine fault-tolerant (BFT) protocols to lower the replica group size from…
How Hard is Asynchronous Weight Reassignment? (Extended Version)
Hasan Heydari, Guthemberg Silvestre, Alysson Bessani
The performance of distributed storage systems deployed on wide-area networks can be improved using weighted (majority) quorum systems instead of their regular variants due to the…
On the Minimal Knowledge Required for Solving Stellar Consensus
Robin Vassantlal, Hasan Heydari, Alysson Bessani
Byzantine Consensus is fundamental for building consistent and fault-tolerant distributed systems. In traditional quorum-based consensus protocols, quorums are defined using global…
Chasing the Speed of Light: Low-Latency Planetary-Scale Adaptive Byzantine Consensus
Christian Berger, Lívio 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…
