A Survey and Ontology of Blockchain Consensus Algorithms for Resource-Constrained IoT Systems [PDF]
Sensors, 2022 The basic properties of blockchain, such as decentralization, security, and immutability, show promising potential for IoT applications. The main feature—decentralization of blockchain technology—depends on the consensus.

A Taxonomic Hierarchy of Blockchain Consensus Algorithms: An Evolutionary Phylogeny Approach [PDF]
Sensors, 2023 Countless endeavors have been undertaken to address the Byzantine Generals Problem, a generalization of the Two Generals Problem. The emergence of proof of work (PoW) for Bitcoin has led to various consensus algorithms diverging, and comparable existing ...

MinMax algorithms for stabilizing consensus [PDF]
Distributed Computing, 2021 In the stabilizing consensus problem, each agent of a networked system has an input value and is repeatedly writing an output value; it is required that eventually all the output values stabilize to the same value which, moreover, must be one of the input values. We study this problem for a synchronous model with identical and anonymous agents that are

Localized State-Change Consensus in Immense and Highly Dynamic Environments
Cryptography, 2022 Consensus algorithms are the building block of any decentralized network where the risk of malicious users is high. These algorithms are required to be robust, scalable, and secure in order to operate properly. Localized state-change consensus (LSC) is a

Enhancing Electronic Voting With A Dual-Blockchain Architecture
Ledger, 2021 Voting is one of the most fundamental aspects of democracy. Over the past few decades, voting methods around the world have expanded from traditional paper ballot systems to electronic voting (e-voting), in which votes are written directly to computer ...

Albatross – An optimistic consensus algorithm [PDF]
2019 Crypto Valley Conference on Blockchain Technology (CVCBT), 2019 The consensus protocol is a critical component of distributed ledgers and blockchains. Achieving consensus over a decentralized network poses challenges to transaction finality and performance. Currently, the highest-performing consensus algorithms are speculative BFT algorithms, which, however, compromise on the transaction finality guarantees offered

An Algorithm for Consensus Trees [PDF]
2020 24th International Computer Science and Engineering Conference (ICSEC), 2020 We consider the tree consensus problem, an important problem in bioinformatics. Given a rooted tree $t$ and another tree $T$, one would like to incorporate compatible information from $T$ to $t$. This problem is a subproblem in the tree refinement problem called the RF-Optimal Tree Refinement Problem defined by in Christensen, Molloy, Vachaspati and ...
