Research on the legal, ethical, and societal aspects of blockchain technology has become increasingly important as its applications expand across finance, healthcare, governance, and other sectors. From a legal perspective, blockchain challenges traditional regulatory frameworks, raising issues related to smart contract enforceability, jurisdiction, liability, and compliance with existing laws. Ethically, concerns include privacy, data protection, informed consent, and the environmental impact of energy-intensive consensus mechanisms, emphasizing the need for responsible and sustainable implementation. Societally, blockchain has the potential to enhance transparency, trust, and inclusivity, but it may also exacerbate inequalities or create new forms of digital exclusion if not carefully managed. Overall, addressing these dimensions is critical to ensuring that blockchain technology develops in a way that is legally sound, ethically responsible, and socially beneficial.
