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.

Group Dinner plans to be announced (everyone pays for themselves)
Tower 44--54: Room 105
The workshop will take place at UPMC Campus Jussieu, which is located
right in the center of Paris, about 10 minutes walk from Notre Dame.
The street address is "4 Place Jussieu, 75005 Paris", and the entrance
into the campus is *only* via Place Jussieu (Rue Jussieu), next to the
Jussieu metro station (which deserves metro lines 7 and 10). The
EuroS&P sessions and registration desk are hosted in the Auditorium of
UPMC Campus Jussieu, which is located between towers 45, 44, 54, and
55. The auditorium is underground and the entrance is via a separate
staircase with a glass cover.
Please carry photo ID due to (possible) security checks by UPMC

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 We solicit previously unpublished papers offering novel contributions in both Bitcoin and wider blockchain research.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:
Novel attacks on blockchain technologies
Improvements to core blockchain cryptographic primitives
Compact ring signatures
Compact range proofs
Privacy-Preserving Signature Aggregation
(De) anonymization of blockchain records
Improvements of SNARKs for blockchain technologies
Formal verification of smart contracts
The security of SPV models
Game theoretic analysis of proof-of-work
Relevant Systematization of Knowledge papers
Security and privacy trade-offs related to scalability and decentralization
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.
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.
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.
