Abstract

This study examines blockchain technology as an enabling infrastructure for consumer centric data governance through the conceptual lens of the sovereign consumer. Departing from platform centric models that frame data privacy primarily as a regulatory compliance or technical security issue, this paper positions consumer sovereignty as both a governance principle and an operational capability. Using a qualitative and analytical research design, the study synthesizes insights from consumer sovereignty theory, digital governance literature, and decentralized systems research to conceptualize how blockchain characteristics namely decentralization, immutability, transparency, cryptography, and smart contracts can be mapped onto core data governance functions. The analysis demonstrates that blockchain has the potential to transform data ownership from a passive legal status into an enforceable and programmable right, allowing individuals to dynamically grant, monitor, and revoke consent over personal data usage. Rather than relying on absolute data concealment, privacy is operationalized through controlled transparency supported by cryptographic safeguards and hybrid on chain and off chain architectures. This governance oriented framework emphasizes accountability, auditability, and user authority without compromising regulatory alignment. Although the proposed framework remains conceptual and does not involve empirical implementation, it provides a structured analytical contribution relevant to AI driven digital ecosystems and sustainable digital development. In particular, the study aligns consumer centric data sovereignty with Sustainable Development Goals SDG 9, SDG 12, and SDG 16 by supporting resilient digital infrastructure, responsible data usage, and transparent governance mechanisms. The findings offer implications for policymakers, platform designers, and organizations seeking privacy oriented digital governance models grounded in consumer empowerment.

Abstract

The rapid growth of digital financial services has significantly increased the volume of online payment transactions, while simultaneously intensifying concerns related to transaction security, data integrity, privacy protection, and fraud due to the limitations of centralized payment architectures, which remain vulnerable to cyberattacks, data manipulation, and single points of failure. This study aims to analyze the role of blockchain technology in enhancing the se- curity of online payment transactions by examining its core characteristics, including decentralization, transparency, immutability, and smart contracts. This research adopts a conceptual and descriptive comparative approach by synthesizing recent peer-reviewed literature to evaluate blockchain-based payment systems in comparison with conventional centralized systems. The findings indicate that blockchain implementation improves transaction security by reducing fraud risks, eliminating single points of failure, ensuring tamperresistant records, and enhancing transparency and traceability, thereby increasing user trust. These improvements contribute to more reliable, transparent, and resilient digital payment infrastructures. Furthermore, blockchain technology supports the SDGs 8 (Decent Work and Economic Growth), SDGs 9 (Industry, Innovation, and Infrastructure), and SDGs 16 (Peace, Justice, and Strong Institutions), by promoting transparency, accountability, and long-term stability in digital financial ecosystems.
