Security and Privacy of Blockchain Technologies

Today, the security and privacy properties of blockchain technologies are still an emerging field that is need of further research. The Bitcoin electronic cash system introduced the new field of blockchain technology as a practical mechanism for a permissionless and censorship-resistant e-cash over the Internet. However, the decentralized network and public verifiability of Bitcoin often do not provide the security and privacy properties assumed by its users. For example, despite a common assumption that Bitcoin is anonymous, transactions can be de-anonymized, limiting the commercial utility of the network and also harms individual privacy. Generalizations of Bitcoin's underlying blockchain technology as a platform for smart contracts by Ethereum are still immature. For example, security issues in the underlying programming language for smart contracts in Ethereum led to the massive DAO hack. More than ever, proper security and privacy properties need to be designed into the underlying framework for blockchain technologies.

Call for Papers

The Security and Privacy on the Blockchain Workshop is the first IEEE forum for research on the security and privacy properties of blockchains as a solution for transactional systems. We solicit previously unpublished papers offering novel contributions in both Bitcoin and wider blockchain research. Papers may present advances in the theory, design, implementation, analysis, verification, or empirical evaluation and measurement of existing systems. Papers that shed new light on past or informally known results by means of sound formal theory or thorough empirical analysis are welcome.

Topics of Interest include:

This topic list is not meant to be exhaustive. S&B is interested in all aspects of the blockchain research relating to security and privacy. Papers that are considered out of scope may be rejected without full review. We encourage submissions that are "far-reaching" and "risky."

Instructions for Paper Submissions

All submissions must be original work; the submitter must clearly document any overlap with previously published or simultaneously submitted papers from any of the authors. Failure to point out and explain overlap will be grounds for rejection. Simultaneous submission of the same paper to another venue with proceedings or a journal is not allowed and will be grounds for automatic rejection. Contact the program committee chair if there are questions about this policy.

Anonymous Submission

Papers must be submitted in a form suitable for anonymous review: no author names or affiliations may appear on the title page, and papers should avoid revealing their identity in the text. When referring to your previous work, do so in the third person, as though it were written by someone else. Only blind the reference itself in the (unusual) case that a third-person reference is infeasible. Contact the program chairs if you have any questions. Papers that are not properly anonymized may be rejected without review.

Page Limit and Formatting

Short position papers may not exceed 4 pages total and full papers may not exceed 10 pages, including references and appendices. Papers must be formatted for US letter (not A4) size paper with margins of at least 3/4 inch on all sides. The text must be formatted in a two-column layout, with columns no more than 9 in. high and 3.375 in. wide. The text must be in Times font, 10-point or larger, with 12-point or larger line spacing. Authors should use the IEEE conference proceedings templates.


Submissions must be in Portable Document Format (.pdf). Authors should pay special attention to unusual fonts, images, and figures that might create problems for reviewers. Your document should render correctly in Adobe Reader XI and when printed in black and white.

Conference Submission Server

Papers must be submitted using Easychair ( and submissions may be updated at any time until the deadline for submissions. The submission site is open.

Publication and Presentation

Authors are responsible for obtaining appropriate publication clearances. One of the authors of the accepted paper is expected to present the paper at the conference. Submissions received after the submission deadline or failing to conform to the submission guidelines risk rejection without review. Accepted publications can be subject to publication in IEEE proceedings. If authors wish to not publish in IEEE, we will also offer an extended abstract version for publishing. This option will be available when papers are accepted. For more information, contact the chairs.


Program Committee


Programme Chair



The workshop program will be announced after paper acceptances have been sent out on January 28th 2017. A keynote will be given by Adam Back (See more info), which may take the form of a panel with other prominent researchers involved in the blockchain. The schedule will feature both paper presentations and an 'open space' (rump session) at the end.
