It introduces Self-Certifying Identifiers (SIDs), User/Service Trustees as trusted proxies, and leverages DNSSEC-secured TXT records to bind public keys to identities. The framework enables privacy-by-design, where real identities are hidden behind trusted entities, through privacy- preserving intermediarie. Credentials bound to SIDs support role- based access control, while ephemeral tokens ensure short-lived authorization. Although initially DNS-dependent, the model can extend to other directories like DIDs or IPFS. This approach aligns with zero-trust architectures and supports automated, AI-driven interactions in future networks.}, }
