An IEEE European Symposium on Security & Privacy Affiliated Workshop

September 7, 2021 (all-digital)

Security & Privacy on the Blockchain (affiliated with Euro S&P 2021)

Cryptocurrencies have emerged as a promising instrument for financial transaction services that provide transparency and integrity in a decentralized fashion. Their clever combination of blockchains with new incentive mechanisms facilitate publicly verifiable and peer-to-peer transactions without a trusted central party. As a result, they have caught the attention of academic researchers, mainstream media, regulators, entrepreneurs and traditional financial institutions. As a subject for academic research, the global and self-enforcing nature of blockchains raises interesting questions and challenges across several disciplines including computer science, law, economics, and human-computer interaction. Our workshop focuses on a wide-range of topics ranging from the scalability of cryptocurrencies, achieving and evaluating financial privacy in public blockchains, permissioning access to blockchains to satisfy regulatory requirements, aligning honest behaviour in blockchain ecosystems and smart contracts through the application of game theory and mechanism design, and the critical analysis of various applications of blockchain to other domains.

Virtual Conference & Workshop Attendee Registration:

The registration fee includes the entrance to all IEEE EuroS&P 2021 conference and workshop sessions. Please note: At least one author per paper presented at the main conference must register as Main Conference or Workshop Author.

Student registration:

Student registrations are only valid after a valid student ID has been uploaded through the registration process. Please note: At least one author per paper presented at the main conference must register as Main Conference or Workshop Author.


The workshop will take place in the following zoom room.

Please join Slack using this link: and join the channel #workshop_s-b

The link to the Zoom Rooms is also linked in the main program of the conference ( as well as in the Slack channel #workshop_s-b.

To access the rooms a password is required, the password will be sent out (only) by the organizers to all registered participants. Therefore, if you have not registered yet, please do so now.

Everyone who is registered will receive a detailed access information including the password and therefore be able to access all workshops and the main conference.


The workshop will take place on September 7. All times shown are in CEST.

Lightning talks

The lightning talks session at IEEE S&B is intended to present work-in-progress from attendees (both from academia and industry) in the form of a short presentation. We strongly encourage submission of a lightning talk on a topic relevant to the workshop.

There are no format requirements for your talk and we do not provide any template. Sign-up for lightning talks will be open until September 6th, 2021, or until all the slots are taken. Register your lightning talk here.


IEEE EuroS&P 2021 and all its workshops, including S&B, are converted into an all-digital event.

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 fifth IEEE Security and Privacy on the Blockchain (S&B) 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 cryptocurrencies 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 papers may not exceed 4 pages and full papers may not exceed 10 pages not including references and appendix.

Papers must be typeset in LaTeX in A4 format (not "US Letter") using the IEEE conference proceeding template we supply ( We suggest you first compile the supplied LaTeX source as is, checking that you obtain the same PDF as the one supplied, and then write your paper into the LaTeX template, replacing the boilerplate text. Please do not use other IEEE templates. Failure to adhere to the page limit and formatting requirements can be grounds for rejection.


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 online and submissions may be updated at any time until the deadline for submissions.

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.
