Aggregate Cash System: a Cryptographic Investigation Of
Aggregate Cash Systems: A Cryptographic Investigation of Mimblewimble Georg Fuchsbauer1,2, Michele Orrù2,1, and Yannick Seurin3 1 Inria 2 École normale supérieure, CNRS, PSL University, Paris, France 3 ANSSI, Paris, France {georg.fuchsbauer, michele.orru}@ens.fr [email protected] Abstract. Mimblewimble is an electronic cash system proposed by an anonymous author in 2016. It combines several privacy-enhancing techniques initially envisioned for Bitcoin, such as Confidential Transactions (Maxwell, 2015), non-interactive merging of transactions (Saxena, Misra, Dhar, 2014), and cut-through of transaction inputs and outputs (Maxwell, 2013). As a remarkable consequence, coins can be deleted once they have been spent while maintaining public verifiability of the ledger, which is not possible in Bitcoin. This results in tremendous space savings for the ledger and efficiency gains for new users, who must verify their view of the system. In this paper, we provide a provable-security analysis for Mimblewimble. We give a precise syntax and formal security definitions for an abstraction of Mimblewimble that we call an aggregate cash system. We then formally prove the security of Mimblewimble in this definitional framework. Our results imply in particular that two natural instantiations (with Pedersen commitments and Schnorr or BLS signatures) are provably secure against inflation and coin theft under standard assumptions. Keywords: Mimblewimble, Bitcoin, commitments, aggregate signatures. 1 Introduction Bitcoin and the UTXO model. Proposed in 2008 and launched early 2009, Bitcoin [Nak08] is a decentralized payment system in which transactions are registered in a distributed and publicly verifiable ledger called a blockchain. Bitcoin departs from traditional account-based payment systems where transactions specify an amount moving from one account to another. -

Bitcoin Microstructure and the Kimchi Premium
Bitcoin Microstructure and the Kimchi Premium Kyoung Jin Choi∗ Alfred Lehary University of Calgary University of Calgary Haskayne School of Business Haskayne School of Business Ryan Staufferz University of Calgary Haskayne School of Business this version: April 2019 ∗Haskayne School of Business, University of Calgary, 2500 University Drive NW, Calgary, Alberta, Canada T2N 1N4. e-mail: [email protected] ye-mail: [email protected] ze-mail: [email protected] Bitcoin Microstructure and the Kimchi Premium Abstract Between January 2016 and February 2018, Bitcoin were in Korea on average 4.73% more expensive than in the United States, a fact commonly referred to as the Kimchi pre- mium. We argue that capital controls create frictions as well as amplify existing frictions from the microstructure of the Bitcoin network that limit the ability of arbitrageurs to take advantage of persistent price differences. We find that the Bitcoin premia are positively re- lated to transaction costs, confirmation time in the blockchain, and to Bitcoin price volatility in line with the idea that the delay and the associated price risk during the transaction period make trades less attractive for risk averse arbitrageurs and hence allow prices to diverge. A cross country comparison shows that Bitcoin tend to trade at higher prices in countries with lower financial freedom. Finally unlike the prediction from the stock bubble literature, the Kimchi premium is negatively related to the trading volume, which also suggests that the Bitcoin microstructure is important to understand the Kimchi premium.

Thesis October 2020 Supervisors: prof. dr. M. J. Uetz (UT) dr. M. H. Everts (TNO/UT) dr. B. Manthey (UT) dr. A. Peter (UT) Department Applied Mathematics Discrete Mathematics & Mathematical Programming Department Computer Science 4TU Cyber Security Faculty of Electrical Engineering, Mathematics and Computer Science University of Twente Preface This thesis concludes my seven years (and a month) as a student. During all these years I have certainly enjoyed myself and feel proud of everything I have done and achieved. Not only have I completed a bachelor’s in Applied Mathematics, I have also spent a year as a board member of my study association W.S.G. Abacus, spent a lot of time as a student assistant, and have made friends for life. I have really enjoyed creating this final project, in all its ups and downs, that concludes not only my master’s in Applied Mathematics but also that in Computer Science. This work was carried out at TNO in Groningen in the department Cyber Security & Ro- bustness. My time there has been amazing and the colleagues in the department have made that time even better. I am also happy to say that I will continue my time there soon. There are quite some people I should thank for helping my realise this thesis. First of all, my main supervisor Maarten who helped me with his constructive feedback, knowledge of blockchains and presence at both TNO and my university. -

Trading and Arbitrage in Cryptocurrency Markets
Trading and Arbitrage in Cryptocurrency Markets Igor Makarov1 and Antoinette Schoar∗2 1London School of Economics 2MIT Sloan, NBER, CEPR December 15, 2018 ABSTRACT We study the efficiency, price formation and segmentation of cryptocurrency markets. We document large, recurrent arbitrage opportunities in cryptocurrency prices relative to fiat currencies across exchanges, which often persist for weeks. Price deviations are much larger across than within countries, and smaller between cryptocurrencies. Price deviations across countries co-move and open up in times of large appreciations of the Bitcoin. Countries that on average have a higher premium over the US Bitcoin price also see a bigger widening of arbitrage deviations in times of large appreciations of the Bitcoin. Finally, we decompose signed volume on each exchange into a common and an idiosyncratic component. We show that the common component explains up to 85% of Bitcoin returns and that the idiosyncratic components play an important role in explaining the size of the arbitrage spreads between exchanges. ∗Igor Makarov: Houghton Street, London WC2A 2AE, UK.
