Cayetana Santaolalla Montoya, “The challenges of blockchain arbitration from a private international law perspective”

This article aims to explore the emergence of blockchain arbitration and the legal challenges it poses from a private international law perspective. It examines the legal implications of this new type of arbitration and its feasibility under international regulatory frameworks (including the European Union, the USA, and the 1958 New York Convention), and it assesses leading decentralized justice platforms such as Kleros, Aragon, and Jur. The study highlights the fundamental differences between blockchain arbitration and traditional arbitration, identifying challenges such as the absence of a seat, the anonymity of parties and arbitrators, and the tension between decentralization and legal oversight. Finally, it explores future trends and proposes recommendations to adapt existing regulatory frameworks, concluding that, while blockchain arbitration will not replace classical arbitration in the short term, it could establish itself as a valuable complement to resolve disputes in the global digital economy.
