Aims and Scope

Since the appearance of Bitcoin in 2009, a plethora of new cryptocurrencies and other blockchain based systems have been deployed with different success. While some of them are slightly different copies of Bitcoin, other ones propose interesting improvements or new usages of the underlying blockchain technology. However, the novelty of such technologies is often tied with rapid developments and proof-of-concept software, and rigorous scientific analyses of the proposed systems are often skipped.

This workshop aims to provide a forum for researchers in this area to carefully analyze current systems and propose new ones in order to create a scientific background for a solid development of new cryptocurrencies and blockchain technology systems.

Title: Anonymity in Cryptocurrencies

Abstract: A long line of recent research has demonstrated that existing cryptocurrencies often do not achieve the level of anonymity that users might expect they do, while at the same time another line of research has worked to increase the level of anonymity by adding new features to existing cryptocurrencies or creating entirely new cryptocurrencies. This talk will explore both of these lines of research, demonstrating both de-anonymization attacks and techniques for anonymity that achieve provably secure guarantees.

Short Biography: Dr. Sarah Meiklejohn is Reader (Associate Professor) in Cryptography and Security at UCL, in the Computer Science department. I am affiliated with the Information Security Group, and am also a member of the Open Music Initiative and the Initiative for Cryptocurrencies and Contracts (IC3).

Before joining UCL, she received a PhD in Computer Science from the University of California, San Diego under the joint supervision of Mihir Bellare and Stefan Savage. During her PhD, she spent the summers of 2011 and 2013 at MSR Redmond, working in the cryptography group with Melissa Chase. She obtained an Sc.M. in Computer Science from Brown University under the guidance of Anna Lysyanskaya in 2009, and an Sc.B. in Mathematics from Brown University in 2008.

Call for posters

We welcome poster abstracts describing works in progress, or innovative ideas not mature enough to be presented as a paper. The poster track will provide an opportunity to present early-stage work and receive feedback from the community, especially on thought-provoking or controversial work, approaches, or ideas from students.

Submit your posters to

Posters shall be submitted for review in the form of an extended abstract that has to be formatted in LNCS-style and not exceed 1 page in length, with a PDF draft of the proposed poster included as page 2 of the submission (A0 size in portrait mode, W 841mm x H 1189 mm, with all fonts embedded in the PDF file). In addition, poster titles should always start with the phrase 'Poster Abstract:'. Accepted posters will be presented at the symposium in a separate session. Authors of accepted full papers are also encouraged to submit and present posters of their paper in the poster session. If the poster submission is for an accepted paper, add the following keywords to your submission: 'Poster for Accepted Paper: '.

Registration stipends for the worshop registration are available for students that present their posters at CBT2018.

Note that the poster abstracts have a separate deadline from the full papers and will not be included in the proceedings.

Please contact in case of doubts and questions.

Call for papers

Submitted papers must be original and not submitted for publication elsewhere. Authors are invited to submit their manuscripts following the LNCS Proceedings Manuscript style. Papers are limited to 16 pages (full papers), or 8 pages (short papers) including references and appendices, and can be submitted as PDF via the CBT 2018 submission site.

Accepted conference papers will be published by Springer in the LNCS collection. At least one author of each accepted paper is required to register and present their work at the workshop; otherwise the paper will not be included in the proceedings.


To register to CBT 2018, please follow the general registration instructions for ESORICS 2018 (kindly specify CBT when registering to the registration service).
