[Agenda] W3C CCG 2025-04-22 on Google Meet (not Jitsi) - Anonymous Credentials from ECDSA

*Main Agenda: Anonymous Credentials from ECDSA*

We are excited to have Abhi Shelat and Matteo Frigo from Google present on
"Anonymous Credentials from ECDSA" at our W3C CCG meeting next Tuesday.
Their paper is available at https://eprint.iacr.org/2024/2010, and their
first draft of the spec can be found at
https://datatracker.ietf.org/doc/draft-google-cfrg-libzk/.

Andrea D'Intin shared Abhi and Matteo's paper in February, and it has
received much attention in our community.  The proposed solution achieves
zero-knowledge selective disclosures on top of existing ECDSA (Elliptic
Curve Digital Signature Algorithm) signature scheme, which could help
accelerate the market adoption of anonymous credentials.  If you have any
questions about this innovative approach, please join us live next Tuesday!

*A friendly reminder that we have moved over to Google
