Security Analysis on Tangle-based Blockchain through Simulation [article]

Bozhi Wang and Qin Wang and Shiping Chen and Yang Xiang
2020 arXiv   pre-print
To the best of our knowledge, this is the first study to provide a comprehensive security analysis of Tangle-based blockchains.  ...  To achieve that, we deconstruct the Tangle-based projects (e.g. IOTA) and abstract the main components to rebuild a simple but flexible network for the simulation.  ...  , and how to select the parent transactions for verification.  ...

This notion is important because we prove that it is a necessary assumption to protect the Tangle against double-spending attacks, and this is true for any tip selection algorithm (which is a fundamental  ...  We hope that it will be used to improve the current protocol with a more formal approach.  ...  However, it is not clear in the definition of the Tangle how this PoW impacts its security.  ...

Classification of k-tangle projections using cascade representation [article]

Andrey Bogdanov, Vadim Meshkov, Alexander Omelchenko, Michael Petrov
2010 arXiv   pre-print
The paper addresses the k-tangle enumeration problem. We introduce a notion of cascade diagram for k-tangle projections.  ...  Tangles projections with up to 12 crossings are tabulated. We provide also pictures of alternating k-tangles with 5 crossing or less.  ...  So, in the sifting stage there is no need to compare projections obtained from different parents.  ...

Metamorphic IOTA [article]

Gewu Bu
2019 arXiv   pre-print
Transactions are continuously appended to an acyclic structure called tangle and each new transaction selects as parents two existing transactions (called tips) that it approves.  ...  Interestingly, to the best of our knowledge this is the first formal analysis of the security guaranties of IOTA and its derivatives.  ...  G-IOTA due to the fact that it manages to choose the third tip randomly, resulted in having equal values as that of IOTA at 15,998 instances the weight of the tangle was computed respectively with the  ...

G-IOTA: Fair and confidence aware tangle [article]

Gewu Bu, Maria Potop-Butucaru
2019 arXiv   pre-print
This paper proposes strategies to improve the IOTA tangle in terms of resilience to splitting attacks. Our contribution is two fold.  ...  Then, we analyze IOTA-tangle from the point of view of confidence fairness and identify its drawbacks. Second, we propose a new selection mechanism, G-IOTA, that targets to protect tips left behind.  ...  It utilizes a data structure called the tangle [6] . The users in IOTA work cooperatively to verify the transactions in the tangle for making the IOTA-tangle safe and reliable.  ...
