Special Issue Information

Dear Colleagues,

Electronic money is well known and widely used. However, when attempting to implement digital cash or digital forms of value, often some properties of real cash are omitted. Especially difficult is the design of a completely decentralized, peer-to-peer currency which prevents double spending on the one hand and allows value exchange in an anonymous form without interaction with a trusted third party. In the last two years, the crypto currency Bitcoin provided an interesting solution to this challenge. The open source project implements a probabilistic solution of a consensus problem and is accepted by its community, the algorithm however is still not sufficiently analyzed from a theoretical point of view.

This special issue of Future Internet is devoted to Bitcoin and to similar approaches to digital cash. Selected contributions from the Bitcoin Workshop (http://bitcoin.uni-rostock.de/index.php) will be published, and papers that explore the latest advances in digital cash regarding its design and observations of its impact are also warmly welcome.

Submission

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Future Internet is an international peer-reviewed Open Access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 500 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

The Bitcoin network of decentralized payment transactions has attracted a lot of attention from both Internet users and researchers in recent years. Bitcoin utilizes a peer-to-peer network to issue anonymous payment transactions between different users. In the currently used Bitcoin clients, the full transaction history is available at each node of the network to prevent double spending without the need for a central authority, forming a valuable source for empirical research on network structure, network dynamics, and the implied anonymity challenges, as well as guidance on the future evolution of complex payment systems. We found dynamical effects of which some increase anonymity while others decrease it. Most importantly, several parameters of the Bitcoin transaction graph seem to have become stationary over the last 12–18 months. We discuss the implications. Full article
