Data is a fundamental asset for organizations. Data spaces emerge as distributed structures that promote secure and reliable data sharing. The International Data Space (IDS) protocol is currently one of the main standards in the data space environment. The growing evolution of data spaces implies the emergence of challenges associated with aspects such as digital sovereignty, decentralization, veracity, security and privacy protection. Distributed Ledger Technologies (DLTs) are emerging as information structures that can provide solutions to these challenges. This paper proposes the migration of trust entities in the IDS architecture, such as the Clearing House, to Hyperledger Fabric Blockchain infrastructure as a solution mechanism to the above challenges. To this end, it presents a Hyperledger Fabric Blockchain interface that guarantees the interaction between an IDS Connector and the blockchain, which is demonstrated in this study with an Eclipse Dataspace Components (EDC) Connector.
