As a consequence of the COVID-19 situation, it has been decided to cancel TPBC20 on the scheduled dates. Once we have more information about the situation, we will consider rescheduling the event to a date later this year. Further updates will be announced on the TPBC20 website  https://eventum.upf.edu/43438/detail/theory-and-practice-of-blockchains.html If you have questions, please contact the workshop organizers.
