21st IEEE International Symposium on Parallel and Distributed Computing
The 21st IEEE International Symposium on Parallel and Distributed Computing (ISPDC) is held in Basel, Switzerland from 11-13 July 2022. We’re proud to announce that Typefi Software Architect, Dinesh Amarasekara, will be presenting a paper at this year’s event!

The IEEE ISPDC 2022 conference aims at presenting original unpublished research as well as oral communications research that targets state-of-the-art as well as emerging topics pertaining to the field of Parallel and Distributed Computing paradigms and applications.
Parallel and Distributed Computing is an important research area today and has a strong contribution to the advancements in science, engineering, and society at large. Its evolution is characterized by the continuous development of new approaches in the modeling, design, analysis, evaluation, and programming of parallel and distributed computing applications and systems.
ZPAXOS: An asynchronous BFT PAXOS with a leaderless synchronous group
On Wednesday, 13 July at 16:30 (CEST), Dinesh, and co-author Nalin Ranasinghe, will virtually present their paper, “ZPAXOS: An asynchronous BFT PAXOS with a leaderless synchronous group”, at the 21st IEEE ISPDC!
This paper presents a novel protocol called ZPaxos, based on early version XPaxos and EPaxos, for consensus achievement in BFT systems. In terms of fault tolerance, the proposed method allows the removal and addition of nodes without system interrupts. The experimental evaluation of ZPaxos is realized against its’ predecessors, and the results show better performance of the new model in terms of latency and throughput.
This paper describes an improved consensus mechanism, ZPaxos, which is an enhanced EPaxos embedding two key features of XPaxos i.e., a synchronous group with fault detection, and a recovery protocol under weak asynchrony assumptions. The new protocol achieves consensus in a single round with a leaderless synchronous group which allows the removal and addition of a node at a time whenever it sees a crashed or a byzantine replica while the system continues servicing requests without any significant interruptions throughout view synchrony.
Don’t miss this opportunity to learn all about ZPAXOS, it’s going to be great!
Registrations for this symposium are now open via the ISPDC website.
