Abstract:
Blockchain technology has rapidly evolved from a financial innovation underpinning cryptocurrencies into a foundational infrastructure for secure digital transactions, smart contracts, and decentralized identity management. Its distributed ledger architecture offers transparency, immutability, and efficiency, yet it simultaneously challenges traditional legal and regulatory frameworks governing contractual enforcement, data protection, and cross-border commerce. This paper provides a comprehensive assessment of the legal and regulatory implications of blockchain technology, focusing on its transformative impact on smart contracts, digital identity systems, and international financial transactions. From a global perspective, it examines how jurisdictions across the European Union, the United States, and Asia are addressing issues such as contractual validity, jurisdictional enforcement, and liability allocation in decentralized networks. The study explores how smart contracts self-executing agreements encoded on blockchain redefine contractual obligations and dispute resolution mechanisms while raising questions about consent, interpretation, and legal recognition under existing civil and commercial laws. Similarly, the emergence of blockchain-based digital identities introduces opportunities for enhanced data sovereignty and privacy protection but also exposes gaps in governance, authentication, and cross-border data portability. In the context of cross-border transactions, the paper analyzes how blockchain’s borderless nature disrupts conventional regulatory oversight and compliance regimes, including anti-money laundering (AML) and know-your-customer (KYC) frameworks. By comparing legislative developments and regulatory experiments worldwide, the research identifies best practices and systemic risks associated with blockchain adoption. Ultimately, the paper proposes a harmonized legal and policy approach that balances innovation with accountability, fostering trust and interoperability in the evolving digital economy.
