Security & Privacy on the Blockchain (affiliated with Euro S&P)

Blockchains---the underlying technology of Bitcoin---have emerged as a promising instrument for transparency and integrity in a decentralized fashion, with an ever-increasing interest from popular media, research, and policy communities. As Bitcoin suffers from scalability and privacy issues that impede its wider adoption, many choose the spectrum of permissioned or a combination of public and private blockchains. With the Security on Blockchain Workshop we propose to look at the major issues in adopting blockchains---both permissioned and permissionless models---as a wide, secure and privacy preserving solution to contemporary problems in various fields: financial, authentication, access control, medical applications, fast data transactions, manufacturing processes, etc. This workshop focuses on the critical analysis of various implementations of blockchain solutions, and the security improvements brought by technologies built on top of blockchains such as Sidechains, Confidential Transactions, Hyperledger, Lightning Networks, and Smart Contracts, and their application to security and privacy in the field.

Call for Papers

The emergence of Bitcoin and decentralized cryptocurrencies, and their fundamental innovation---blockchains---have allowed for entities to trade and interact without a central trusted third party. This has led to a captivating research activity in multiple domains and across different venues, such as top security and distributed systems conferences and journals, as well as a vibrant startup rush on this new technology.

The second IEEE Security and Privacy on the Blockchain workshop aims to unite interested scholars as well as industrial members from all relevant disciplines who study and work in the space of blockchains. We solicit previously unpublished papers offering novel contributions in both Bitcoin and wider blockchain research.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 through empirical analysis are welcome. Suggested contribution topics include (but are not limited to) empirical and theoretical studies of:

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 now closed.

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.
