Blockchain, Smart Contracts, and the Future of Legal Transactions

Abstract

The emergence of blockchain technology has fundamentally transformed the architecture of trust, transparency, and enforcement in legal transactions. By enabling decentralized, immutable, and cryptographically verifiable records, blockchain challenges traditional legal institutions that have historically relied on intermediaries such as courts, financial institutions, and regulatory authorities to establish trust and validate transactions. In this evolving digital ecosystem, smart contracts—self-executing agreements embedded in blockchain code—further redefine contractual relationships by automating performance, reducing transaction costs, and minimizing the need for human intervention. This article critically examines the legal implications of blockchain and smart contracts, with particular emphasis on their impact on foundational principles of contract law, mechanisms of dispute resolution, regulatory compliance, and evidentiary standards. It interrogates whether algorithmic execution can adequately substitute for legal interpretation and equitable considerations traditionally exercised by courts. Additionally, the article explores persistent challenges, including issues of enforceability, jurisdictional ambiguity in cross-border transactions, technological vulnerabilities, and the rigidity of coded agreements. While blockchain technology promises increased efficiency, transparency, and security in legal transactions, it simultaneously raises complex questions regarding legal accountability, allocation of liability, and the adaptability of existing legal frameworks. The analysis underscores that uncritical reliance on technological solutions may undermine core legal values such as fairness and justice. Accordingly, the article concludes that a hybrid legal approach—integrating technological innovation with established doctrinal safeguards and regulatory oversight—is essential for responsibly shaping the future of legal transactions in an increasingly digital society.
