The .DEFAULT profile configures the behavior of the computer before a specific user signs in (such as the Windows Lock and Sign-In Screen).

Recent research proposes mechanisms like , which publishes a daily, randomized revocation list in the form of a cascaded Bloom filter on the blockchain. This allows a wallet to check a credential's status without revealing the specific credential being checked, preserving user privacy. Another example is zk-X509 , a system that bridges legacy X.509 certificates (the standard used in PKI) with blockchain, allowing for "trustless CRL revocation" using zero-knowledge proofs to verify a certificate's chain and status without revealing the entire certificate.
stands for "Identity Client Runtime Library."
