The rise of digital globalization necessitates robust cross-border data sharing mechanisms, presenting challenges in security, privacy, and regulatory compliance. This paper introduces a novel blockchain-based framework to address these challenges, facilitating secure and efficient data exchange while meeting diverse international compliance requirements. Our approach combines advanced cryptographic techniques with smart contracts to create a dual-layered blockchain architecture. The first layer provides participant anonymity through zero-knowledge proofs, and the second ensures traceable, compliant data transactions. This solution streamlines compliance with varied data protection laws, offering a transparent and privacy-preserving platform for global data sharing initiatives. It promises significant benefits for entities engaged in multinational operations, enhancing security, simplifying regulatory adherence, and protecting user privacy.
