3rd International Workshop on Cryptocurrencies and Blockchain Technology SeptemberSep 26 2019 - SeptemberSep 27 2019 Europe/MadridUniversity of Luxembourg, Luxembourg


Since the appearance of Bitcoin in 2009, a plethora of new cryptocurrencies and other blockchain based systems have been deployed with different success. While some of them are slightly different copies of Bitcoin, other ones propose interesting improvements or new usages of the underlying blockchain technology. However, the novelty of such technologies is often tied with rapid developments and proof-of-concept software, and rigorous scientific analyses of the proposed systems are often skipped.

This workshop aims to provide a forum for researchers in this area to carefully analyze current systems and propose new ones in order to create a scientific background for a solid development of new cryptocurrencies and blockchain technology systems.
