About
Dr. Nibesh is an applied researcher at Supra with a general interest in the design of efficient protocols for Byzantine fault tolerant distributed consensus, blockchains, random beacons, distributed key generation, etc. He recently completed my PhD in Computer Science from Rochester Institute of Technology in July 2023, under the guidance of Prof. Kartik Nayak.
Interests and expertise
His primary research focus lies in the realm of secure distributed computing. Over the years, he has dedicated my efforts to designing efficient Byzantine fault-tolerant distributed consensus protocols, as well as delving into topics such as randomness beacons and distributed key generation.
Commentary
I've been actively engaged in designing efficient Byzantine Fault Tolerant (BFT) consensus protocols like Moonshot at Supra. Additionally, I'm delving into enhancing decentralized oracles and refining the data dissemination layer for consensus. Another area of focus is optimizing the latency of DAG-based BFT protocols and investigating efficient Distributed Key Generation (DKG) protocols.
