In the meantime, the application of blockchain will exhibit a variety of complicated problems and new requirements, which brings more open issues and challenges for research communities. </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><br></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">IEEE Blockchain-2021 will be held in December 2021, Melbourne, Australia. The goal of this conference is to promote community-wide discussion identifying the advanced applications, technologies and theories for blockchain. We seek submissions of papers that invent novel techniques, investigate new applications, introduce advanced methodologies, propose promising research directions and discuss approaches for unsolved issues.</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><br></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><b>* Important Dates</b></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><font class=" classDarkfont classDarkfont" color="#e14141">Paper Submission: August 05, 2021, Thursday</font></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Notification of Acceptance: September 18, 2021, Saturday</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Registration and Camera-ready Due: October 06, 2021, Wednesday</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Conference Dates: December 06 -

Submitted papers must not substantially overlap with papers that have been published or that are simultaneously submitted to a journal or a conference with proceedings. Papers must be clearly presented in English, must not exceed 8 pages in IEEE Computer Society proceedings format (or up to 10 pages with the pages over length charge), including tables, figures, references and appendices. Papers will be selected based on their originality, significance, relevance, and clarity of presentation assessed by at least three reviewers. All submitted papers will be judged through double-blind reviews, where the identities of the authors are withheld from the reviewers. As an author, you are required to preserve the anonymity of your submission, while at the same time allowing the reader to fully grasp the context of related past work, including your own. Papers that do not conform to our double-blind submission policies will be rejected without review.</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><br></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Submission of a paper should be regarded as a commitment that, should the paper be accepted, at least one of the authors will register and attend the conference to present the work. IEEE Blockchain 2021 reserves the right to exclude a paper from distribution after the conference (e.g., removal from the digital library and indexing services), if the paper is not presented at the conference. All accepted papers will be published in IEEE CPS proceedings (EI Indexed) and collected by IEEE Xplore Digital Library. Two outstanding papers will be selected to receive the Best Paper Awards. </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><br></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><b>* Instruction for Double-blind Submission</b></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"> • Remove the names and affiliations of authors from the title page.</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"> • Remove acknowledgments.</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"> • Remove project titles or names that could be used to trace back to the authors via web search.</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"> • Carefully name your files to anonymize author information.</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"> • Carefully refer to related work, particularly your own. Do not omit references to provide anonymity, as this leaves the reviewer incapable of grasping the context. Instead, reference your past work in the third person, just as you would any other piece of related work by another author. For example, instead of "In prior work [1], we presented a scheme that ...," sentences in the spirit of "In prior work, Clark et al. [1] presented a scheme that ..." should be used. With this method, the full citation of the referred paper can still be given, such as "[1] A. Clark …., "Analysis of...", and it is not acceptable to say "[1] Reference deleted for double-blind review."</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"> • The submitted manuscript or its title/abstract should not be posted on a public website, such as arxiv.org, or transmitted via public mailing lists.</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"> • The submitted manuscript (PDF file) should be text-searchable. Any submission that does not meet this requirement may be returned without review.</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"> • Many of the editing tools automatically add metadata to the generated PDF file containing information that may violate the double blind policy. Please remove any possible metadata that can link your manuscript to you. This includes removing names, affiliation, license numbers etc. from the Metadata as well as from the paper. Failing to meet this requirement may also lead to a rejection without review.</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><br></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><b>* Organizing Committees</b></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">General Co-Chairs</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Robert Deng, Singapore Management University, Singapore </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Yong Xiang, Deakin University, Australia </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Salil Kanhere, UNSW, Australia</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><br></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Program Co-Chairs</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Honggang Wang, University of Massachusetts Dartmouth, USA </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Valtteri Niemi, University of Helsinki, Finland </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Yang Xiang, Swinburne University of Technology, Australia</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><br></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Program Vice-Chairs</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Joseph Liu, Monash University, Australia </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Mariusz Nowostawski, Norwegian University of Science and Technology, Norway </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Ziyuan Wang, Swinburne University of Technology, Australia</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><br></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Summit Chair</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Jin Li, Guangzhou University, China</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><br></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Publicity Co-Chairs</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Jiangshan Yu, Monash University, Australia </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Qinghua Lu, CSIRO Data61, Australia </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Longxiang Gao, Deakin University, Australia </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Xueqin Liang, Aalto University, Finland</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><br></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Workshop and Symposia Co-Chairs</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Qiang He, Swinburne University of Technology, Australia </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Xiao Chen, Monash University, Australia</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;"><br></div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Publication Co-Chairs</div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Xingliang Yuan, Monash University, Australia </div><div style="font-family: Helvetica, Helvetica, 微软雅黑, 宋体;">Xiaochun Chen, Middlesex University, UK</div></div>
