Online Conference Program:

  • All registered conference participants have received an email invitation to sign up for the virtual space of the joint online conferences, which is hosted on Moodle at If you are registered but have not received the invitation email, please contact the Executive Organisation Chair Prof. Hong Zhu by email at
  • From August 3rd, conference participants can view the presentations of the papers recorded by the authors and submitted to the virtual space. The papers are available to view from the virtual space on Moodle, too. All conference proceedings are available for download. The virtual space also contains technical programmes, Zoom Room listings, and forums for discussions, information about keynote and panel sessions, even a virtual social event section.
  • How to prepare for the live sessions: At the online conference sessions, the recorded videos will NOT be played. Instead, each author will give a 5-minute summary of the work followed by live discussions in the form of answering questions from the audience. All participants are strongly encouraged to view the videos, read the papers and prepare some questions for live discussions at the sessions.
  • Live sessions: Please note that all plenary sessions (i.e. events across all co-located six conferences), including keynotes, panels, opening session, and closing and award session are all live sessions. The schedules can be found on the virtual space on the Moodle website at
  • Offline activities: In addition to live discussions at the sessions, each session also has a separate forum on the virtual space for you to post comments and questions in advance of the session and/or after the session for asynchronous text-based discussions.
  • Platform for online video sessions: The conference sessions will be on the Zoom platform. In particular, each conference will have a dedicated Zoom room for the sessions of that conference, and an additional dedicated breakout room for informal meet-ups for the conference participants. Please joint the Zoom room a few minutes earlier because the sessions will start on time. Links to the Zoom rooms are available on the Moodle website at
  • Slack: There are several Slack channels available for all conference participants, which can be used for, for example, real-time communication or for starting a threaded discussion around particualr topics, or for easily sharing materials with other participants. In order to join these channels, please follow the invite link available at
  • Have a great conference!

July 10, 2020:

  • DAPPS 2020 and all co-located conferences will take place as a virtual online event.
  • Authors' presentations will consist of both 1) summarizing live talks during the online conference followed by a live Q&A session for each paper as well as 2) pre-recorded talks, available for watching prior to the conference.
  • The online event will be accompanied by a number of additional live plenary sessions and keynotes.
  • Paper presentations, plenary sessions, and keynotes will take place on August 4, 5, and 6. The first conference day on August 3 will be dedicated to watching paper presentations and meeting informally online.
  • More information about DAPPS' schedule will be available by July 17, 2020.

July 9, 2020:

March 16, 2020:

  • New conference date for IEEE DAPPS and all co-located conferences: August 3-6, 2020. The venue remains the same (Keble College, Oxford, UK). If you currently have an existing accommodation booking for the original April dates and want to attend in August: we will provide a facility to convert your booking to the new dates soon.
  • Authors of accepted papers who cannot attend the August event on site will have the option to present their paper remotely.
  • We hope you all are doing well and look forward to welcoming you in August!

March 10, 2020:

  • IEEE DAPPS and the co-located conferences will be postponed to summer 2020 due to the Covid-19 outbreak. The exact new date of the conference will be announced very soon (within a week).
  • Making this decision has not been easy. This decision was made by the joint steering committee of the co-located conferences after numerous discussions and telephone calls, several rounds of consultations with IEEE's Event Organisation Team, and renegotiations with the venue host. We have taken into consideration the current state and predictions officially announced by the UK government and many other countries. We have carefully compared various options, such as running the conferences online, completely canceling the conferences, and running it as it was scheduled plus online presentations for those who cannot attend, etc., assessed the impacts on both the academic and scientific quality of our event, the health and well-beings of conference delegates, as well as the financial viability. We believe that this is the most responsible reaction to the current situation of Covid-19 outbreak.
  • This is the refund policy for the registration fees and accommodation bookings:
    • Authors’ registrations cannot be refunded. Authors who still cannot attend the conference in person at the postponed dates due to good reasons will be allowed to present their work online remotely.
    • Non-author registrations can be refunded upon request, but will have to be deducted by 10% of the registration fees to cover the cost of bank transactions and online registration facility usage fees.
    • Accommodation bookings can be refunded upon request, but also have to be deducted by 10% of the booking price to cover the cost of bank transactions and online registration facility usage fees.
    • For non-author registrations and accommodation bookings, please consider to delay your refund request until you finally decide not to attend, because if you make a future registration for the postponed event or accommodation booking after the refund, it will be treated as a new booking by the registration tool.
    All refund requests must be made on the registration website.
  • The organizing committee of IEEE DAPPS 2020 can be reached via email at:
  • We will provide another status update here by Monday, March 16, 2020 at the latest. Stay healthy.

Call for papers


The objective of the 2nd IEEE International Conference on Decentralized Applications and Infrastructures (IEEE DAPPS 2020, formerly known as IEEE DAPPCON) is to facilitate the exchange between researchers and practitioners in the area of Decentralized Applications based on Distributed Ledger Technologies, Blockchains and related technologies. The conference will be co-located with IEEE SOSE, IEEE Mobile Cloud, IEEE BigDataService, and IEEE AITest.

It can be already seen today that Blockchain is making a huge impact on the way digital payments are made. However, the potential implications of Blockchain technologies go far beyond their application as the technological backbone for cryptocurrencies. In recent years, Decentralized Applications (dApps) have emerged as a new model for building massively scalable services.

dApps allow for various novel application scenarios, which are built upon distributed consensus and thus are hard to block or censor. While Blockchains such as Bitcoin or Ethereum are currently based on compute-intense consensus mechanisms, more recent approaches focus on voting or staking-based algorithms that support higher transactions per second and are also better-suited to reflect proportions of majority ownership, which are required in many enterprise application scenarios.

IEEE DAPPS 2020 will provide a high-quality forum for participants from research and industry. The conference will discuss key theories, algorithms, infrastructures, and significant applications for Decentralized Applications and Infrastructures, as well as emerging research topics.

Topics of interest include, but are not limited to:

  • Blockchain Theory
  • Distributed Ledger Technologies (DLT)
  • Smart Contract Theory
  • Consensus protocols for dApps
  • Infrastructures for dApps
  • Communication protocols and standards for dApps
  • Decentralized Identity
  • Identity Management for dApps
  • Token Economy
  • dApps/DLT/Blockchain Analytics
  • dApps/DLT/Blockchain Governance
  • dApps/DLT/Blockchain Interoperability
  • dApps/DLT/Blockchain Privacy
  • dApps/DLT/Blockchain Security
  • dApps/DLT/Blockchain Scalability and performance
  • dApps/DLT/Blockchain Policy/law
  • dApps/DLT/Blockchain Applications in areas such as Internet of Things, Logistics, or Health
  • dApps/DLT/Blockchain emerging research topics

Important Dates

  • Nov. 30, 2019 Dec. 7, 2019: Paper submission deadline
  • Jan. 15, 2020: Author notification
  • Feb. 14, 2020: Camera-ready submission and conference registration

Paper submission

IEEE DAPPS 2020 solicits research papers describing novel and previously unpublished scientific contributions to the field of Decentralized Applications and Infrastructures.

Two different types of papers can be submitted:

  • Regular papers (10 pages IEEE double column format)
  • Short papers (6 pages IEEE double column format)

Regular papers should describe novel and previously unpublished scientific contributions to the field of Decentralized Applications and Infrastructures. Each regular paper is limited to 10 pages, including tables, figures and references.

Short papers aim at presenting novel work in progress, novel applications, and novel industry perspectives in the field of Decentralized Applications and Infrastructures. Each short paper is limited to 6 pages, including tables, figures and references. Short papers will also be peer-reviewed, however, they will be evaluated with a focus on the potential for establishing new ideas and for sparking the interest of participants.

All papers must be written in English. Manuscripts must include a title, an abstract with 200-250 words, and a list of 4-6 keywords. All papers must be prepared in the IEEE double column proceedings format. Please see:

IEEE DAPPS 2020 uses a double-blind review policy. Authors are required to remove their names, affiliation(s) and other identifying information from the header of the manuscript. This also includes meta-data in the submitted document as well as acknowledgement sections. Papers that do not meet these anonymization requirements may be rejected without further review.

Authors are encouraged, but not required, to cite their previous work in a neutral manner, for example, avoid “in our previous work [3]” and instead use “as shown in [3]”.

All submitted papers will be peer-reviewed. The name(s) of the author(s) will not be visible to the reviewers of a paper. The name(s) of the author(s) will be visible in the submission system to the General Chairs and the Program Committee Chairs. Authors should report any conflict of interest with the list of Program Committee members during submission of the manuscript, in which case the Program Committee Chairs will exclude the corresponding PC member(s) from reviewing the paper.

Authors must submit their manuscripts via the following link by November 30 December 7, 2019, 23:59 GMT at the latest:


Authors who have submitted articles for publication by the IEEE may be interested in posting preprint versions of the same article. In order to find out more about the allowed forms of preprints and to understand what counts as a prior publication, please see IEEE's Sharing and Posting Policies as well as Section 8.1.9 on "Electronic Information Dissemination" in the IEEE Publication Services and Products Board Operations Manual.
