        <jats:abstract xml:lang="en">
          <jats:p>In today’s increasingly interconnected world, organizations interact with complex data ecosystems that feature multiple independent stakeholders. Establishing trust, transparency, as well as integrity concerning such ecosystems is a difficult task, particularly if stakeholders feature conflicting interests with different, unintegrated information systems. Conventional, centrally managed systems are prone to single-point failures, manipulations, as well as delays within the verification process. Blockchain technology, with its decentralized, immutable system, provides a sound basis for addressing such issues. BC-4Track, a blockchain-enabled system, is presented as a solution that provides secure, transparent, as well as tamper-proof management of lifecycle information within the automotive industry. This system incorporates IoT-based smart kits for real-time information acquisition, Ethereum-based smart contracts for automated record management, as well as a web-based decentralized application (DApp) that enables stakeholder interaction. Thorough analyses were carried out with a focus on system functionality, system efficiency, and system reliability. System usability, system responsiveness, and system security were validated. These results demonstrate the applicability of blockchain-based solutions in such environments with multiple stakeholders, with regard to issues such as trust.</jats:p>
