Robust and Automated Reconfiguration of Byzantine Wide-Area Replication
Rowdy Chotkan, Bulat Nasrulin, Johan Pouwelse +1
Distributed systems handle adversarial nodes through redundancy, which imposes a significant performance overhead. In blockchain systems, Byzantine fault-tolerant state-machine rep…
SwarmSearch: Decentralized Search Engine with Self-Funding Economy
Marcel Gregoriadis, Rowdy Chotkan, Petru Neague +1
Centralized search engines control what we see, read, believe, and vote. Consequently, they raise concerns over information control, censorship, and bias. Decentralized search engi…
Optimizing Streamlined Blockchain Consensus with Generalized Weighted Voting and Enhanced Leader Rotation
Diana Micloiu, Rowdy Chotkan, Jérémie Decouchant
Streamlined Byzantine Fault Tolerant (BFT) protocols, such as HotStuff [PODC'19], and weighted voting represent two possible strategies to improve consensus in the distributed syst…
Reliable Communication in Hybrid Authentication and Trust Models
Rowdy Chotkan, Bart Cox, Vincent Rahli +1
Reliable communication is a fundamental distributed communication abstraction that allows any two nodes of a network to communicate with each other. It is necessary for more powerf…
