SIROCCO 2019 Review

The conference was held from July 1st to July 4th at Gran Sasso Science Institute (GSSI) in the heart of L'Aquila, Abruzzo, a historic city in Italy to the east of Rome. First Day On the rst day, a tutorial on Permissioned Blockchains took place. There, Roger Wattenhofer covered a variety of topics on permissioned and permissionless blockchains. The rst part started from the very basics, targeting an audience that has never heard of fault-tolerant distributed systems. In the second part, permissionless blockchains were explained, followed by the third and nal part, in which more advanced topics and current research were discussed. The 6-hour tutorial was well attended by researchers and students from various areas and the interactive format allowed the members of the audience to steer the talk into their preferred directions. In the evening, after the registration, the welcome reception with lots of delicious snacks and refreshing drinks took place.
