Blockchain - the technology behind Bitcoin - is flourishing into an impressive spectrum of research projects and initiatives, corporate alliances, and startup companies. This multidisciplinary effort spans diverse disciplines ranging from Computer Science and Engineering to Communications, Social Sciences, Public Policy, Banking and Finance, Journalism, and Political Sciences to name a few. This one-day event strives to bring researchers and practitioners of blockchain together to share and exchange results. We are interested in papers and presentations on a broad range of topics including:

    Application use cases of blockchain
    Secure smart contracts
    Blockchain for social networking
    Distributed systems for blockchain
    Blockchain consensus protocols
    Governance and blockchain
    Partitioned and replicated data stores for blockchain
    Transactions and blockchain
    Software engineering practices and life cycle management of blockchain
    Social aspects of blockchain
    Game theory and its applications to blockchain
    Blockchain protocol analysis and security
    Algorithm design, complexity analysis, implementation for blockchain
    Experience papers with blockchain

Submission categories:

All papers must be original and not simultaneously submitted to another journal or conference. The following paper categories are welcome. Authors can submit a paper in one of the following categories:

 * Research Papers describe research work in the broad area of blockchain. We solicit both regular papers (up to 16 pages in OASIcs format) and short papers (up to 8 pages in OASIcs format). The former will tend to be descriptions of complete technical work, while the latter will tend to be descriptions of interesting, innovative ideas, which nevertheless require more work to mature. For short papers, we also encourage submissions that put previously published work in a new light or describe extensions of previously published work by the authors. These limits exclude references and appendices.
 * Industrial Papers describing experiences with the deployed and state-of-the-art blockchain systems. These papers can also be either regular papers (up to 16 pages in OASIcs format) or short papers (up to 8 pages in OASIcs format).
 * Posters. Researchers and practitioners wishing to showcase and get feedback on work that is in an early stage, and hence not yet ready for publication as a paper, are invited to submit a 1-page proposal for a poster. All accepted papers are encouraged to showcase a poster, too.

All submissions will be held to a high-quality standard, and evaluated based on their originality, technical merit, topical relevance, value to the community, and likelihood of leading to insightful discussions. Submissions will be kept confidential. On rare occasions, regular paper submissions may be accepted as short papers (pending authors’ approval and significant shortening).

Submission guidelines:

Papers must meet the following formatting rules and be submitted to EasyChair at

in order to be considered for publication. They should be submitted in PDF format and formatted using the OpenAccess Series in Informatics (OASIcs) LaTeX template available at https://submission.dagstuhl.de/documentation/authors.

Judicious use of color is permitted, but please bear in mind that not everybody has access to a color printer, and some people cannot distinguish some colors. Figures should be clear when printed in black & white.
Symbols and axis labels used in graphs should be legible as printed, and not require magnification.

Following the list of author names and affiliations on the first page, submissions should include a line that specifies the paper’s "type" (research, industrial, or poster) and "length" (regular or short).


All accepted regular papers will be published open access by OASIcs (OpenAccess Series in Informatic) and will receive a DOI. Authors will retain their copyright and papers will be published at https://drops.dagstuhl.de/ under a Creative Commons CC BY license.
