Colloated with EuroS&P and Eurocrypt 2016. Today, the security and privacy properties of blockchain technologies are still an emerging field that is need of further research. The Bitcoin electronic cash system introduced the new field of blockchain technology as a practical mechanism for a permissionless and censorship-resistant e-cash over the Internet. However, the decentralized network and public verifiability of Bitcoin often do not provide the security and privacy properties assumed by its users. For example, despite a common assumption that Bitcoin is anonymous, transactions can be de-anonymized, limiting the commercial utility of the network and also harms individual privacy. Generalizations of Bitcoin’s underlying blockchain technology as a platform for smart contracts by Ethereum are still immature. For example, security issues in the underlying programming language for smart contracts in Ethereum led to the massive DAO Hack. More than ever, proper security and privacy properties need to be designed into the underlying framework for blockchain technologies.
The Internet Freedom Festival is front event aiming to gather various kind of people concerned by privacy and freedom. This was the occasion to bring both new technologies to a broader audience (autocrypt) but also conduct field interviews to produce an embed knowledge of the impact of encryption and internet on communities.
The whole team met to discuss last advances in sub-projects. Autocrypt team have presented their new UX design approach in order to bring easy encryption to the mass. Claimchain is still at an early stage but fundamental technical considerations have been discussed.
Alfredo Pironti (ioactive) have also presented a shord talk about PGP: 15 years of broken emails… and we are still doing it wrong”
This ‘Open source’ discussion between Francesca Musiani and the cryptographer Ludovic Perret was animated by a journalist.
Abstract: Access to all kinds of data and the ability to collect and exploit them have now reached an unprecedented level. We are facing a unique paradox: we have to give thought to the issues of both access to data and data protection, with an emphasis on personal data protection. How does cryptology - then the science of secrecy, now a science based on trust - evolve, in today’s and tomorrow’s contexts? How should individuals now adapt their behaviours?”
Harry Halpin gave this talk aimed at designers and artists interested in privacy issues and served on the jury panel to chose the Crypto Design Award winner.

“Materializing governance by information infrastructure”, a talk by Francesca Musiani.
When we talk about blockchains as “part of the Web”, we face some specific questions: How does this fit into the same origin security model of the Web? What are the privacy implications, especially when talking about identity management? What part of the Web stack would be involved: client-side, server-side, protocols, interchange formats? What is the relationship to payments, including W3C’s Web Payments work.
