Abstract
Secure, user-centered solutions for digital identities and their verification shape the future of privacy-friendly interactions in a connected world. Novel Verifiable Credentials,based on Distributed Ledger Technologies (DLT) and Decentralized Identity (DID),
combine application areas such as digital IDs, tamper-proof certificates, or passwordless web logins. This work analyzes the technical foundations, cryptographic methods,
and recommendations of the World Wide Web Consortium (W3C) for their implementation to evaluate their potential for DID-based digital signatures. By comparing the
technical characteristics of Distributed Ledger Technologies, such as their architectures,
consensus algorithms, and transaction costs, as well as a prototype implementation of
a DID-based Verifiable Credential solution, economic implementation approaches are
examined. Pseudonymity, legal frameworks, cryptographic security, and their quantum
resistance are analyzed to highlight opportunities and challenges of a decentralized infrastructure for digital identities.
