The paper examines the essence of cryptocurrency as a method payment has been investigated and identifies its key features (exchange for goods or services; exchange classic currency; minimum level possibility abduction; payments, fast direct transactions; investment asset; business development in cryptocurrency). Different approaches to determining legal nature are analyzed (cryptocurrency paym...

Cryptography relies on the secrecy of keys. Measures of information, and thus secrecy, are called entropy. Previous work does not formally assess the cryptographically appropriate entropy of secret keys. This report defines several new forms of entropy appropriate for cryptographic situations. This report defines statistical inference methods appropriate for assessing cryptographic entropy.

The invention of the Bitcoin protocol has opened the door to new forms of financial interaction. One such form may be to adapt Bitcoin technology for use as a community currency. A community currency is a form of money issued by a non-government entity to serve the economic or social interests of a group of people, often in a small geographic area. We propose a model of a community cryptocurren...

Secure decentralized namespaces have recently become possible due to cryptocurrency technology. They enable a censorship-resistant domainname system outside the control of any single entity, among other applications. Namecoin, a fork of Bitcoin, is the most prominent example. We initiate the study of decentralized namespaces and the market for names in such systems. Our extensive empirical anal...

Since its inception, the blockchain technology has shown promising application prospects. From the initial cryptocurrency to the current smart contract, blockchain has been applied to many fields. Although there are some studies on the security and privacy issues of blockchain, there lacks a systematic examination on the security of blockchain systems. In this paper, we conduct a systematic stu...

Title of dissertation: PROVABLE SECURITY FOR CRYPTOCURRENCIES Andrew Miller, Doctor of Philosophy, 2016 Dissertation directed by: Professor Jonathan Katz and Professor Elaine Shi Department of Computer Science The past several years have seen the surprising and rapid rise of Bitcoin and other “cryptocurrencies.” These are decentralized peer-to-peer networks that allow users to transmit money, t...

Cryptocurrency returns are highly nonnormal, casting doubt on the standard performance metrics. We apply almost stochastic dominance, which does not require any assumption about return distribution or degree of risk aversion. From 29 long–short cryptocurrency factor portfolios, we find eight that dominate our four benchmarks. Their cannot be fully explained by three-factor coin model Liu et al....

The study aimed at showing how to create and release cryptocurrency, based on which one can introduce a new generation of this money that can continue its life in the quantum computers space and study whether cryptocurrency could be controlled or the rules should be rewritten in line with new technology. Regarding this, we showed the evolution of money and its uses in economic relations. Accord...
