2nd Distributed Ledger Technology Workshop (DLT 2019)

Co-located with

the Third Italian Conference on Cybersecurity (ITA-SEC 2019)

February 12th, 2019

Istituto di Informatica e Telematica
Consiglio Nazionale delle Ricerche
via G. Moruzzi, 1


Distributed Ledger Technology (DLT) is having an ever growing popularity. Nowadays, the most popular application of DLT concerns cryptocurrencies (Bitcoin, Litecoin, Monero, etc.), but the DLT features allow them to be applied in many scenarios, 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.


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

  • Blockchain foundations
  • Privacy and anonymity on blockchain
  • Smart Contracts
  • Smart Contracts analysis
  • Performance and scalability of blockchain based systems
  • Lightweight protocols based on blockchain
  • Attacks to blockchain based systems
  • Transactions analysis
  • Energy consumption issues
  • Applications of blockchain technologies
  • Legal aspects of blockchains


The workshop accepts two kind of contributions: “research papers” and “oral communications”. Both contributions entail an oral presentation at the workshop. Research papers expected length is 15 pages (Easychair style), even though shorter contributions describing position papers or extended abstracts are welcome. All accepted research papers will be included in the ITASEC proceedings published on CEUR (to be confirmed). Selected contributions will be included in a special issue of Frontiers in Blockchain (https://www.frontiersin.org/journals/blockchain).


Paper submission: December, 10 2018 December, 18 2018
Oral communication abstract submission: December, 10 2018 December, 18 2018
Acceptance Notification: January, 21 2019
