In this talk we examine the GNU Name System (RFC 9498) a decentralized directory protocol with a reference implementation in GNUnet. We present its features, potential governance models and future developments including, in particular, the challenges a PQC transition of the cryptography poses. We also investigate two potential use cases of GNS: 1. Use of GNS as an alias lookup component in digital, privacy-friendly payments using GNU Taler. 2. Sharing personal information without the need for centralized identity provider services while still allowing asynchronous, secure access to the data for relying parties.
