Abstract:
Securing and managing distributed data in federated ecosystems is a key challenge when data protection, sovereignty and interoperability need to be guaranteed at the same time. Previous blockchain-based solutions often reach their limits in terms of integration capability and fine-grained access mechanisms. This theoretical paper presents a multilayered architecture concept that integrates Hyperledger Fabric into the Gaia-X ecosystem. Advanced encryption methods and a smartcontract- based reassembly logic are used to securely distribute fragmented data and make it accessible only to authorized actors. The approach promotes digital sovereignty and scalability within Gaia-X-compliant data spaces and serves as an initial conceptualbasis that will be technically validated and further developed in future work.
