BBS pseudonymous identifier issues – forever unlinkability
- Issue: Given colluding verifiers sharing pseudonymous identifiers and a (future) quantum computer calculation, unlinkability can be broken.
- Proposals:
  - Document risk in the spec – at minimum.
  - Add in a vector of secrets that would prevent breaking unlinkability up to "n" uses of the credential.
  - Implement a ZKP proof of the pseudonymous identifier.
