Fair Exchange Is Incomparable to Consensus [chapter]

Simona Orzan, Mohammad Torabi Dashti
Lecture Notes in Computer Science  
In asynchronous systems where processes are prone to crash failures, we show that fair exchange is incomparable to distributed consensus.  ...  Remarkably, this is in contrast to the folklore belief that solving fair exchange is generally harder than solving distributed consensus. *  ...  Now, we turn to the requirements of FE. Fair exchange aims at exchanging items in a fair manner.  ...

2015 ACM SIGecom Exchanges  
A single algorithm is provided for each application, even in cases where several incomparable approaches are present in the fair division literature.  ...  The solution is also consensual : if there is a division that agrees with all players' reports, then it is the outcome.  ...

Multi-party negotiation with preferences rather than utilities

Fabien Delecroix, Maxime Morge, Thomas Nachtergaelle, Jean-Christophe Routier
2016 Multiagent and Grid Systems  
We prove that our negotiation process is always successful and reach fair agreements when the agents are cooperative.  ...  We propose here a multi-party negotiation game where agents exchange offers over a single issue.  ...  Acknowledgements The authors would like to thank the reviewers for their comments on this paper.  ...

The failure detector abstraction

Felix C. Freiling, Rachid Guerraoui, Petr Kuznetsov
2011 ACM Computing Surveys  
That is, we survey the weakest failure detector question and illustrate how failure detectors can be used to classify problems.  ...  A failure detector is a fundamental abstraction in distributed computing. This paper surveys this abstraction through two dimensions.  ...  Acknowledgments We wish to thank Martin Hutle for comments on a previous version of this paper and the anonymous reviewers for the constructive feedback.  ...

Accountability and Reconfiguration: Self-Healing Lattice Agreement [article]

Luciano Freitas de Souza, Petr Kuznetsov, Thibault Rieutord, Sara Tucci-Piergiovanni
2021 arXiv   pre-print
It is natural to complement fault detection with a reconfiguration mechanism, so that the system could heal itself, by replacing malfunctioning parts with new ones.  ...  An accountable distributed system provides means to detect deviations of system components from their expected behavior.  ...  asynchronous and that it is composed by a set Π of processes that communicate over reliable message-passing channels exchanging authenticated messages.  ...

ORGAN SALES NEEDN'T BE EXPLOITATIVE (BUT IT MATTERS IF THEY ARE)

ROB LAWLOR
2010 Bioethics  
Acknowledgements For helpful comments on an earlier draft presented in Leeds, I am grateful to Daniel Elstein, Gerald Lang, Jussi Suikkanen, Georgia Testa and Pekka  ...  But if we appeal to incomparability, we can't say that £1000 is not a fair price for a kidney. This claim relies on the very comparison that is ruled out according to incomparability.  ...  to my claim that there can't be an imbalance in both directions might be to appeal to incomparability.  ...

A short introduction to failure detectors for asynchronous distributed systems

Michel Reynal
2005 ACM SIGACT News  
Many thanks to Michel for his contribution to this issue.  ...  This is not at all surprising as failure detection is pervasive in the design, the analysis and the implementation of a lot of fault-tolerant distributed algorithms that constitute the core of distributed  ...  Acknowledgments I would like to thank David Powell (from LAAS) for interesting discussions, constructive remarks and useful comments that helped improve the paper.  ...

Classification of Foreign Operations For Financial Reporting

Fawzi Laswad, Melvin Roush
2000 Pacific Accounting Review  
No support is found for the assertion that the use of qualitative factors in accounting standards results in dissimilar judgements (lack of consensus) across respondents.  ...  The New Zealand (NZ) standard on foreign currency translation , similar to standards in the US, Australia, and Canada and the International Accounting Standard (IAS-21), requires the classification of  ...  Consistency In addition to consensus, consistency is another indication of judgement validity.  ...

Chain of Antichains: An Efficient and Secure Distributed Ledger Technology and Its Applications [article]

Jinwook Lee, Paul Moon Sub Choi
2019 arXiv   pre-print
Rewards (boxcoin) are paid to the contributing nodes of the ecosystem whose trust is built on the doubly-secure protocol of confirmation.  ...  Although the original distributed ledger technology (DLT) of blockchain is deemed secure and decentralized, the confirmation of transactions is inefficient by design.  ...  The authors would like to express sincere gratitude to Professor Endre Boros for his kind critics, which inspired the authors to come up with a consensus algorithm.  ...

Profit-Taking Rate Guideline Based on Fiqh Muamalat Perspective

Jasni Sulong, Fathullah Asni
2018 International Journal of Academic Research in Business and Social Sciences  
Hence, if profit-taking activities is multiplied extra than the normal standard, it can lead to the implication of ad'afan muda'afah.  ...  The methodology of the study is qualitative, in which datas and informations were collected through literature studies and then scrutinized using content analysis.  ...  Hence synthetically, this illustrates that a multiplied profit-taking that is incomparable with its loss is in contrary with the Islamic teaching.  ...

Aleph: A Leaderless, Asynchronous, Byzantine Fault Tolerant Consensus Protocol [article]

Adam Gągol, MichałŚwiętek
2019 arXiv   pre-print
It is based on a distributed construction of a partially ordered set and the algorithm for reaching a consensus on its extension to a total order.  ...  In this paper we propose Aleph, a leaderless, fully asynchronous, Byzantine fault tolerant consensus protocol for ordering messages exchanged among processes.  ...  Acknowledgements The authors would like to thank Johan Bratt for introducing us to the field, constant support, and many hours spent on valuable discussions.  ...

Safety-Liveness Exclusion in Distributed Computing

Victor Bushkov, Rachid Guerraoui
2015 Proceedings of the 2015 ACM Symposium on Principles of Distributed Computing - PODC '15  
The motivation of this work is to study the extent to which safety and liveness properties inherently exclude each other.  ...  In the context of consensus for example, this means that it is impossible to determine the strongest (resp. the weakest) liveness property that can (resp. cannot) be ensured with linearizability.  ...  Acknowledgements We are very grateful to Cheng Wang who discovered the mistake on the example of an adversary set for consensus.  ...

Dealing with Incommensurability for Dessert and Desert: Comments on Chapman and Katz

1998 University of Pennsylvania law review  
The related, but different claim of incomparability is that there are items or choices of which it cannot sensibly be said that one is better than the other (or that the two are equally good) .  ...  Isaiah Berlin famously argued, in a series of books, that the plurality of values showed the basic flaws of monistic and Utopian strains in political thought, strains that go back to the Enlightenment  ...  Life is not always fair.  ...
