The power of Facebook derives from its control over your digital identity. However, the fundamental technologies behind anonymous (attribute-based) authentication credentials have existed since the mid-90s. This talk will cover new advances in anonymous authentication credentials, how the work was nearly killed by Facebook, and their real-world implementation, including their use in the Nym project's mix-net, cryptocurrency, and decentralized messaging applications.
How do we pratically defeat Facebook and build an anonymous internet? Let's start with the building blocks: Getting rid of Facebook Connect using decentralized and privacy-enhancing technologies, then using that as a lever to build the rest of the system. Anonymous authentication credentials have existed since early blind signature schemes, but have historically been both inefficient and required centralized (if often blind!) trusted third parties. New advances such as UnlimitID and the Coconut signature scheme have allowed the creation of "Nym credentials" that are both decentralized and privacy-preserving. We'll go into three use-cases:
