Evaluating DAG-Based Blockchains for IoT

TLDR
This paper defines desired criteria for evaluating these two blockchains, provides an in-depth analysis on the two systems, and identifies open challenges IOTA and Hashgraph are facing for their application in IoT.
Abstract
Blockchain has been considered as the enabler to provide automated and trust-less Internet of things (IoT) services. However, legacy consensus mechanisms applied in most of the blockchain networks pose obstacles for deployment in IoT in respect of decentralization and scalability. The emerging Directed Acyclic Graph (DAG)-based models aim at delivering the benefits of blockchain without making compromise on performance. This paper gives a critical analysis on the two representative DAG-based models, IOTA and Hashgraph. In particular, we provide an insightful overview of the two blockchains, with their features and functionalities. We define desired criteria for evaluating these two blockchains, provide an in-depth analysis on the two systems, and identify open challenges IOTA and Hashgraph are facing for their application in IoT.

The Byzantine Generals Problem

TL;DR: The Albanian Generals Problem as mentioned in this paper is a generalization of Dijkstra's dining philosophers problem, where two generals have to come to a common agreement on whether to attack or retreat, but can communicate only by sending messengers who might never arrive.

The Byzantine generals problem

TL;DR: In this article, a group of generals of the Byzantine army camped with their troops around an enemy city are shown to agree upon a common battle plan using only oral messages, if and only if more than two-thirds of the generals are loyal; so a single traitor can confound two loyal generals.
