Call for papers


The objective of the 3rd IEEE International Conference on Decentralized Applications and Infrastructures (IEEE DAPPS 2021) 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, IEEE AITest, and IEEE JCC.

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 a plethora of highly expressive applications.

dApps allow for various novel application scenarios, which are built upon distributed consensus and thus are hard to block or censor while providing public verifiability of peer-to-peer transactions without a trusted central party. For that, permissionless Blockchains such as Bitcoin or Ethereum rely on an unrestricted set of participants that run a (often time-consuming) consensus algorithm among them. In contrast, permissioned Blockchains, such as Hyperledger Fabric, distribute trust among a restricted set of consensus participants, a setup that can be well suited to model enterprise application scenarios in a more scalable fashion.

IEEE DAPPS 2021 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:

  • Distributed Ledger Technologies (DLT)
  • Smart contract theory
  • Languages and tools for (secure) dApps
  • Infrastructures for dApps
  • Communication protocols and standards for dApps
  • Decentralized identity
  • Identity management for dApps
  • Token Economy
  • Off-chain dApps
  • dApps/DLT/Blockchain analytics
  • dApps/DLT/Blockchain governance
  • dApps/DLT/Blockchain interoperability
  • dApps/DLT/Blockchain privacy
  • dApps/DLT/Blockchain security
  • dApps/DLT/Blockchain scalability, sharding, and performance
  • dApps/DLT/Blockchain policy/law
  • dApps/DLT/Blockchain applications in areas such as Internet of Things, logistics, supply chain, or health
  • dApps/DLT/Blockchain emerging research topics

Important Dates

  • Apr. 27, 2021: Paper submission deadline
  • May. 4, 2021: Paper submission deadline (extended)
  • Jun. 18, 2021: Author notification (delayed)
  • Jun. 28, 2021: Camera-ready submission and conference registration

Paper submission

IEEE DAPPS 2021 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, and a list of 4-6 keywords. All papers must be prepared in the IEEE double column proceedings format. Please see:

IEEE DAPPS 2021 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. Authors are 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]”. Papers that do not meet these anonymization requirements may be desk-rejected without further review.

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 May 4th, 2021, 23:59 AoE 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.

Paper publication

All accepted papers will be published by IEEE Computer Society Press (EI-Index) and included in the IEEE Digital Library. For publication, each accepted paper is required to be registered by one of its authors, and at least one author is required to attend and present the paper at the conference for the paper to be included in the final technical program and the IEEE Digital Library.
