Abstract: Blockchain technology is rapidly becoming a cornerstone of the EUʼs digital economy, ensuring secure, transparent, and efficient digital transactions. It reduces reliance on intermediaries, strengthens data integrity, and transforms established business practices in supply chain management, digital identity systems, and the financial sector. Research into current sectoral models of blockchain application in the EU economy is critically important, as it allows for the identification of specific industries, which can gain the greatest economic benefit from the implementation and scaling of this technology. It also helps to reveal the unique challenges and opportunities for each sector.

The research methodology is based on a content analysis of blockchain technology application models across various sectors of the European Unionʼs economy. This primarily involves the systematization and generalization of existing models, an examination of their common and distinctive characteristics, a comparative analysis of sectoral cases of successful blockchain implementation, and the identification of its universal advantages. The purpose of this article is to investigate and systematize the sectoral models of blockchain technology application in the European Union.

The expansion of blockchain technology beyond the financial sector into fields such as agriculture, energy, industry, media, real estate, and healthcare demonstrates its universality as a fundamental technology for ensuring data integrity across various economic sectors. The technological features of blockchain (immutability, transparency, decentralization) have found their application wherever it is critical to ensure transparent data accounting and mutual trust among parties in a system of multilateral economic cooperation.
