Distributed Ledger Technology (DLT) is having an ever growing popularity. The first applications of DLT concern cryptocurrencies (Bitcoin, Litecoin, Monero, etc.), but the DLT disruptive features enable several applications in many scenarios of interest both in research and business contexts. In particular, the possibility of executing Smart Contracts makes the DLT technology suitable to be adopted in a large number of application fields, being Internet of Things, Cyber Physical Systems, Edge Computing, and Supply Chain Management, only some examples. At the same time, the adoption of DLT opens new challenges in terms of privacy, security, scalability, sustainability and decentralization.

Scope

This workshop is a forum for researchers, developers, and users to discuss issues related to Distributed Ledger Technology and its adoption in research and business scenarios. The primary goal is to foster discussion and cross-fertilisation of ideas among experts in different fields related to DLTs, and thus advance the national and international state-of-the-art. Research, applications, case studies, and experiences concerning DLT are all encouraged with a special focus on the privacy and security issues.


The topics of interest of the workshop includes (but are not limited to):

* Blockchain foundations
* Consensus protocols
* Cryptography for blockchains
* Privacy and anonymity on blockchains and their applications
* Attacks to/through smart contracts
* Formal verification of blockchain protocols and smart contracts
* Scalability of blockchains and their applications
* Lightweight protocols based on blockchains
* Smart contracts and their applications
* Decentralized finance
* Transactions analysis
* Energy consumption issues
* Applications of blockchain technology
* Decentralization and governance in DLT
* Non-fungible tokens
* Oracles, bridges and interoperability of blockchains
* Game theory and blockchains


Contributions


The workshop accepts three kinds of contributions: 1) “regular research papers”, 2) “short research papers” and “oral communications”. Submissions of all kinds of contributions, if accepted, entail an oral presentation at the workshop.

Regular and short research papers must include original results (i.e., results not published yet and not concurrently under submissions neither to a conference/workshop with proceedings, nor to a journal). Research results in the form of position papers or SoKs are also welcome. It is expected that regular and short research papers will be evaluated by 3 reviewers. All accepted (both regular and short) research papers will be included in the DLT 2023 proceedings published on CEUR-WS. Rejected (both regular and short) research papers will be then evaluated as oral communications unless the authors specify in the submission right after the title that "the paper should not be considered for oral communications".

Regular research papers should have a minimum length of 10 pages and a maximum length of 15 pages followed by bibliography and an appendix. Reviewers are not required to read the appendix. Additionally, there is a plan to invite extended full versions of selected regular research papers for a special issue of a journal. More details will be announced in the next version of this call for papers.

Short research papers should have a minimum length of 4 and a maximum length of 8 pages followed by a bibliography (no appendix is allowed).

Submissions of oral communications are expected to be short with a maximum of 2 pages and are not required to follow a specific format. The review process of submitted oral communications will be lighter and the notification will consist of just a short sentence motivating acceptance or rejection. Since oral communications will not appear in the proceedings, such submissions can also refer to already published results.
