Call For Papers EXTENDED: Blockchains and Decentralized Identification


Update: Due to popular request, the deadline for this Call for Papers has been EXTENDED to 30 June 2021!

is currently seeking submissions for a special issue on the topic of Blockchains and Decentralized Identities and Identification (DID), to be published in the fourth quarter of 2021.

The trend toward digitization and the increasing number of digitized services have created a need for safe and secure digital identities and identification processes. On one hand, interoperability, regulations, and governance require something like a common framework for identities; on the other hand, data protection, self-sovereignity and heterogeneity call for decentralization—such as is provided by blockchain and distributed ledger technologies.

Worldwide, a countless number of projects are developing methods, interfaces, use cases, and standards for decentralized identities (DID) and identification. Examples are company-based projects and products such as Lissi or SelF (, EBSI hosted by the European Union (, ESSIF (, and sovrin ( as an international identity project.

This trend has encouraged us—the editors of Ledger—to open a call-for-papers for research on or academic or scholarly solutions about blockchain-based, distributed ledger-based, or other decentralized identity systems.

There are no further restrictions on topics or use cases.

If you are:

  • Developing or contributing to a DID-solution using blockchains, ledgers, or other distributed systems, and
  • You have research work to be published
  • In a free, open-access journal*

then you are cordially invited to submit a scholarly paper or to volunteer to serve as a reviewer.

Submission Deadline EXTENDED: 30 June 2021
Timeline: Due to the extended deadline, publication is now expected in the fourth quarter of 2021.

If you have questions or suggestions, please contact the principal editor of the special issue, Prof. Dr. Volker Skwarek, directly, at Please include "Blockchain and DID" in the subject of your email.
