Recursive Energy Efficient Agreement

TL;DR

This paper introduces a recursive algorithm for energy-efficient agreement in distributed systems, significantly reducing active participation rounds to minimize energy costs, especially in fault-prone environments.

Contribution

It presents a novel recursive agreement algorithm that achieves logarithmic active rounds relative to the number of crash faults, improving energy efficiency in distributed agreement protocols.

Findings

Active rounds per participant are reduced to O(log f)

The algorithm effectively handles crash faults in distributed systems

Energy costs are minimized through reduced participation

Abstract

Agreement is a foundational problem in distributed computing that have been studied extensively for over four decades. Recently, Meir, Mirault, Peleg and Robinson introduced the notion of \emph{Energy Efficient Agreement}, where the goal is to solve Agreement while minimizing the number of round a party participates in, thereby reducing the energy cost per participant. We show a recursive Agreement algorithm that has $O(\log f)$ active rounds per participant, where $f<n$ represents the maximum number of crash faults in the system.
