Call for Workshop and Special Session Proposals The IEEE Blockchain 2020 workshops and special sessions provide vibrant opportunities for academic researchers and industry practitioners to share their research experiences, original research achievements and practical development products on specific new challenges and emerging issues related to Blockchain. The themes of the Blockchain 2020 workshops and special sessions should be related to the scopes of the main conference, reflecting to advances in all aspects of blockchain. The organizers of the workshops and special sessions shall have responsibility of soliciting call for papers, forming program committee to review and select papers as well as planning workshop/session program. The registration fees for workshops and special sessions will be determined by and paid to the main conference other than the workshops or sessions. The main conference will provide workshop/session facilities including the working notes printing, meeting rooms, coffee breaks, lunches, dinners, proceedings, etc. The proceedings of the IEEE Blockchain 2020 workshops and special sessions will be published by in IEEE CPS proceedings (EI Indexed) and collected by IEEE Xplore Digital Library. Prospective Workshop Organizers should send a proposal containing the following information to IEEE Blockchain 2020 Workshop Chairs via email by Jan. 05, 2020: - Title of the workshop/session (Full name and Abbreviation) - Objectives, scope, and contribution to the main conference (up to 1 page) - Short bio of the key organizers and their experience on conference/workshop organization - Procedures for selecting papers, plans for advertising call for papers, and intentions for organizing journal special issues if possible - The expected number of participants - A tentative list of program committee members - The workshop website URL address if available Approved workshops should strictly follow the Important Dates of the main conference, particularly the Author Notification Date and the Camera-ready Paper Due Date. The submission deadline could be later than that of the main conference. But, a workshop should have sufficient time, say 5-7 weeks, for generating peer reviews. Generally, each paper should receive 2 or 3 peer reviews. In order to encourage the workshop/session organizers, the main conference will also provide the following benefits to the workshop/session organizers: (1) If a workshop will have at least 10 full registrations for accepted papers (excluding those borderline papers transferred from the main conference), then one of the main organizers can choose either to waive one of his or her papers for registrations or to get the travel grant to attend the conference. (2) If a workshop/session will have at least 20 full registrations for accepted papers (excluding those borderline papers transferred from the main conference), then the main organizers can also invite one keynote speaker for the workshop and the conference will provide free registration and travel grant for the keynote speaker. Look forward to your stimulating proposals and contributions to IEEE Blockchain 2020!
