4th Distributed Ledger Technology Workshop (DLT 2022)

Co-located with ITASEC 2022

June 20, 2022

Auditorium della Tecnica

The last years have witnessed an impressive and increasing interest around Distributed Ledger Technology (DLT) and blockchains. A huge number of application fields, including finance, health, industry, IoT, just to mention some of the most popular ones, are experiencing the advantages of reliable and unalterable information storage and exchange without any trusted third party. This large interest makes discussion on open problems more pressing, like, for example, regarding privacy, scalable and low-latency architectures, interoperability, off-chain solutions, legal aspects, etc. Intersections of blockchains with other technological trends, like, AI, big data, IoT, Industry 4.0, are further interesting discussion topics.

Workshop Scope

The DLT2022 workshop is an international forum for researchers, developers, and users to discuss achievements and issues related to Distributed Ledger Technologies and blockchains, their adoption in business scenarios, and novel ideas in the field. The primary goal is to foster discussion and cross-fertilisation of ideas among experts in different fields related to DLTs, and thus advance the international state-of-the-art. Research, applications, case studies, and experiences concerning DLTs and blockchains are all encouraged.

  • Legal aspects of blockchains (e.g, regulation, law enforcement, etc.)
  • Regulatory sandboxes and their applications

Submission of Contributions

The DLT2022 workshop accepts two kinds of contributions: “research papers” and “oral communications”. Both contributions entail an oral presentation at the workshop. Research papers expected length is at most 15 pages (EasyChair style), even though shorter contributions describing position papers or extended abstracts are welcome. All accepted research papers will be included in workshop proceedings published on CEUR. Selected research papers will be invited for publication in a special issue of International Journal of Parallel, Emergent and Distributed Systems (Taylor&Francis). Oral communications will not be included in the proceedings. The authors shall indicate their choice to contribute with oral communication, writing it alongside the title in the EasyChair form, i.e., “Title (Oral Communication)” and providing only a 1-2 pages abstract outlining the structure of the talk. Oral communications are meant to stimulate the discussion of ongoing research activities or already published results that authors consider relevant for the community.

Instructions for authors.

Submit your paper or oral communication to DLT 2022 by the EasyChair submission system

Instructions for camera ready

Oral communication abstract submission: 6 May 2022 at 18:00 CEST
Acceptance Notification: 20 May 2022

Keynote speaker

Remote Keynote by Vanishree Rao on the MINA Blockchain Technology.

Mina - A Blockchain in its True Sense

The utopian idea of blockchain that started with Satoshi Nakomoto’s whitepaper focused on the goals of decentralization and user anonymity. While various blockchains approached this idea from different directions, they tend to fall back on these goals, as we will reason in the talk.

Using zkSNARKs, a powerful cryptographic tool, we are building the Mina Protocol that achieves decentralization and user anonymity. In this talk, we will see how the base layer works — the way in which zkSNARKs help create Mina. We will also discuss the special privacy-powered applications called zkApps and some examples.
