Scalable byzantine reliable broadcast (extended version)

R Guerraoui, P Kuznetsov, M Monti, M Pavlovic… - arXiv preprint arXiv …, 2019 - arxiv.org
Byzantine reliable broadcast is a powerful primitive that allows a set of processes to agree
on a message from a designated sender, even if some processes (including the sender) are …

On the push&pull protocol for rumour spreading

H Acan, A Collevecchio, A Mehrabian… - Proceedings of the 2015 …, 2015 - dl.acm.org
The asynchronous push&pull protocol, a randomized distributed algorithm for spreading a
rumour in a graph G, is defined as follows. Independent exponential clocks of rate 1 are …

[HTML][HTML] Rumor spreading with bounded in-degree

S Daum, F Kuhn, Y Maus - Theoretical Computer Science, 2020 - Elsevier
In the gossip-based model of communication for disseminating information in a network, in
each time unit, every node u can contact a single random neighbor v but can possibly be …

Universal protocols for information dissemination using emergent signals

B Dudek, A Kosowski - Proceedings of the 50th Annual ACM SIGACT …, 2018 - dl.acm.org
We consider a population of n agents which communicate with each other in a decentralized
manner, through random pairwise interactions. One or more agents in the population may …

How to spread a rumor: Call your neighbors or take a walk?

G Giakkoupis, F Mallmann-Trenn… - Proceedings of the 2019 …, 2019 - dl.acm.org
We study the problem of randomized information dissemination in networks. We compare
the now standard push-pull protocol, with agent-based alternatives where information is …

On achieving scalability through relaxation

G Nadiradze - 2021 - research-explorer.ista.ac.at
The scalability of concurrent data structures and distributed algorithms strongly depends on
reducing the contention for shared resources and the costs of synchronization and …

Who started this rumor? Quantifying the natural differential privacy of gossip protocols

A Bellet, R Guerraoui, H Hendrikx - … International Symposium on …, 2020 - drops.dagstuhl.de
Gossip protocols (also called rumor spreading or epidemic protocols) are widely used to
disseminate information in massive peer-to-peer networks. These protocols are often …

Game Dynamics and Equilibrium Computation in the Population Protocol Model

D Alistarh, K Chatterjee, M Karrabi… - Proceedings of the 43rd …, 2024 - dl.acm.org
We initiate the study of game dynamics in the population protocol model: n agents each
maintain a current local strategy and interact in pairs uniformly at random. Upon each …

Repeated Game Dynamics in Population Protocols

D Alistarh, K Chatterjee, M Karrabi… - arXiv preprint arXiv …, 2023 - arxiv.org
We initiate the study of repeated game dynamics in the population model, in which we are
given a population of $ n $ nodes, each with its local strategy, which interact uniformly at …

Near-optimal leader election in population protocols on graphs

D Alistarh, J Rybicki, S Voitovych - … of the 2022 ACM Symposium on …, 2022 - dl.acm.org
