IOTA / Tangle Research
'The first glance at the simulation of the Tangle: discrete model'
Analyses different tip selection mechanisms and their comulative weight progression and tips number stability.
'Extracting Tangle Properties in Continuous Time via Large-Scale Simulations'
Bartosz Kusmierz, Philip Staupe
Same as Bartosz Kusmierz (2017), but a lot more extensive and over a continuous time model (which is more realistic).
'Probability of being left behind and probability of becoming permanent tip in the Tangle'
Bartosz Kusmierz, Alon Gal
"We formalize, analyze and numerically estimate probability that given transaction will be left behind and probability that transaction will become permanent tip."
'Improving the Anonymity of the IOTA Cryptocurrency'
Assesses the applicability of privacy-improving methods currently used by other cryptocurrencies to IOTA.
'Quasi-Analytic Parasite Chain Absorption Probabilities in the Tangle'
Analyses and simulates with which probability the MCMC random walk gets absorbed into a parasite chain.
'The Stability and the Security of the Tangle'
The original IOTA whitepaper. Presents the Tangle structure, inner workings as well as possible attack scenarios.
'Local modifiers in the Tangle'
Introduces local modifiers that allow different nodes to interact with the Tangle in different ways, depending on information locally available to them.
'On the timestamps in the tangle'
Concludes that while it is impossible to establish correct time order of Tangle transactions, confidence intervals for timestamps can be reasonably accurate.
'Equilibria in the Tangle'
Serguei Popov, Olivia Saa, Paulo Finardi
Proves existence of Nash equilibria for the Tangle when a part of players tries to optimize their attachment strategies.
Other Consensus Mechanisms
Amir Haleem, Andrew Allen, Andrew Thompson, Marc Nijdam, Rahul Garg
A decentralized (IoT) machine network with intrinsic blockchain.
'DEXON Consensus Algorithm'
Presents the "Infinitely Scalable, Low-Latency Byzantine Fault Tolerant Blocklattice" DEXON Consensus Algorithm.
'Hedera: A Governing Council & Public Hashgraph Network'
Leemon Baird, Mance Harmon, Paul Madsen
Open, fast, fair and decentralized public ledger built on the Hedera Hashgraph consensus algorithm.
'Protocol for Asynchronous, Reliable, Secure and Efficient Consensus (PARSEC)'
Pierre Chevalier, Bartlomiej Kaminski, Fraser Hutchison, Qi Ma, Spandan Sharma
Yonatan Sompolinsky, Yoad Lewenberg, Aviv Zohar
Partial synchronous consensus mechanism.
'Security Review IOTA Wallet "TRINITY"'
accessec GmbH - Sebastian Rohr, Iratxe Garrido, Janis Kinast

'STRIDE/DREAD Analysis - Threat Modelling of Trinity Wallet'
Cybersecurity Lab - M. Masoom Alam
Demonstrates that the IOTA Foundation and the Trinity team have taken considerable measures for hardening the security of the Trinity wallet.
Research on Sybil Attacks
'The Sybil Attack in Sensor Networks: Analysis & Defenses'
James Newsome, Elaine Shi, Dawn Song, Adrian Perrig
Presents mechanisms to detect and prevent sybil attacks in a decentralized (sensor) network with (nearly) no added costs.
'Detecting the Sybil Attack in Mobile Ad hoc Networks'
Chris Piro, Clay Shields, Brian Neil Levine
Presents the first completely passive approach to detecting a Sybil attacker in a network by using monitoring nodes.
