Stochastic stability of continuous time consensus protocols
, 2012 A unified approach to studying convergence and stochastic stability of continuous time consensus protocols (CPs) is presented in this work. Our method applies to networks with directed information flow; both cooperative and noncooperative interactions ...

Running Time Analysis of Broadcast Consensus Protocols [PDF]
Foundations of Software Science and Computation Structures24th International Conference, 2021 AbstractBroadcast consensus protocols (BCPs) are a model of computation, in which anonymous, identical, finite-state agents compute by sending/receiving global broadcasts. BCPs are known to compute all number predicates in $$\mathsf {NL}=\mathsf {NSPACE}(\log n)$$ NL ...

Developing a guideline for clinical trial protocol content: Delphi consensus survey [PDF]
Trials, 2012 Background Recent evidence has highlighted deficiencies in clinical trial protocols, having implications for many groups. Existing guidelines for randomized clinical trial (RCT) protocol content vary substantially and most do not describe systematic ...

Good, Better, Best! - Unbeatable Protocols for Consensus and Set Consensus [PDF]
Discussion Paper, Center for the Study of Rationality, 2013 While the very first consensus protocols for the synchronous model were designed to match the worst-case lower bound, deciding in exactly t+1 rounds in all runs, it was soon realized that they could be strictly improved upon by early stopping protocols. These dominate the first ones, by always deciding in at most t+1 rounds, but often much faster.

Distributed Weight Selection in Consensus Protocols by Schatten Norm Minimization
, 2014 In average consensus protocols, nodes in a network perform an iterative weighted average of their estimates and those of their neighbors. The protocol converges to the average of initial estimates of all nodes found in the network.

Blockchain Consensus Protocols in the Wild
31st International Symposium on Distributed Computing (DISC 2017), 2017 A blockchain is a distributed ledger for recording transactions, maintained by many nodes without central authority through a distributed cryptographic protocol. All nodes validate the information to be appended to the blockchain, and a consensus protocol ensures that the nodes agree on a unique order in which entries are appended.

On Consensus under Polynomial Protocols [PDF]
arXiv, 2011 In this paper we explore the possibility of using computational algebraic methods to analyze a class of consensus protocols. We state some necessary conditions for convergence under consensus protocols that are polynomials.
