Supporting application R&D on Ethereum and decentralized platforms.
Group Signatures with zkSNARKs a demo by Joel G, Matt Katz, Uma R, Kevin Z, Raymond Z, and gubsheep zkSNARKs turn cryptography problems into programming tasks. The programmability of zkSNARK circuits allows them to emulate and extend a wide variety of cryptographic primitives which previously required the construction of new mathematical protocols. In this post, we break down a basic zkSNARK construction that implements an old cryptographic primitive—the “group signature scheme.” We also demonstrate a proof-of-concept implementation of an anonymous message board based on this scheme.…
