Recent advancements in cryptography on consumer devices (like your mobile phone) and progress in developer tooling (Semaphore, SnarkJS) have led to the emergence of open-source projects such as Zupass, a personal "cryptographic computer" helping power Devcon.

This talk dives into the technical challenges behind scaling ZKPs to 10,000+ consumer devices and the history behind the project, from its inception at Zuzalu to its usage at recent Ethereum events (Devconnect, ProgCrypto, ETHBerlin).

Stage 6

Behind Zupass: Applied Cryptography For Consumers

0xPARC community developers will present apps built on top of the Programmable Cryptography stack, including FROGCRYPTO, Zupass, Meerkat, and many more. This session will also include a live workshop where you can learn to build your own, and there may be a cryptographic prize for those who complete the challenges…
