This repository contains the requirements for a verifiable credential revocation scheme suitable for use with AnonCreds. We are looking for a replacement for the AnonCreds v1.0 Revocation Scheme, known formally as CKS Signatures. The existing scheme is not sufficiently scalable and privacy preserving for the anticipated "jurisdiction-level" use cases for AnonCreds--one or more credentials for every resident of jurisdiction. In looking for a replacement, we need to define what the requirements are for a sufficiently privacy-preserving and secure scheme. The purpose of this repository is to capture and document those requirements.

This work is being carried out under the Community Specification License v1.0. Any person or organization willing to adhere to this license is welcome to participate in this Working Group and contribute to the development of the specification. Please read the Contributions document in this repo for details. For those unfamiliar with the Community Specification License, you can think of it as analogous to an open source code license, such as Apache 2.0, but for specifications.
All participants in this working group must follow the group's Code of Conduct.
Meetings of the Working Group are held weekly on Mondays at 7AM Pacific/Vancouver time. That is 16:00 CET for most of the year, except for the periods around the daylight savings time changes. Meeting details, agendas, notes and links to the recordings are posted on the repository Wiki (to be done).
The working group has an AnonCreds Specification Discord channel for participants. Invitations for those interested: https://discord.gg/hyperledger.
