Chaumian credentials are about forty years old and still work well, provided your Issuer is willing to bear the cost of running the blind signature protocol for each credential it issues — and that the Resource doesn’t mind verifying a signature for each “show”. Protocols like PrivacyPass implement this using protocols like blind RSA signatures, so presumably these operations cost isn’t prohibitive for real-world applications. However, PrivacyPass also includes some speed optimizations for cases where the Issuer and Resource are the same entity, and these make a big difference.1
