The use of blockchain technology in the public procurement system: international legal experience

Abstract

The subject of the research is the analysis of international experience in the application of blockchain tech
nology in public procurement systems, with particular reference to China, United Kingdom, Japan, Mexico,
and South Korea. The purpose of the scientific work is to examine the theoretical and international legal as
pects of the use of blockchain technology in public procurement systems. The methodological basis of the re
search includes a set of general scientific and private scientific methods, such as systemic, structural
functional, historical, and analysis synthesis, comparative law. The principles of transparency, fair competi
tion, equal access for participants, and legality are outlined in regulatory legal acts regulating the field of pub
lic procurement, which in turn forms the legal basis for organizing the procurement process. To fully imple
ment these principles, the introduction of distributed ledger technologies, such as blockchain, is considered a
harmonious direction. Blockchain technology ensures data immutability and allows you to obtain an accurate
digital footprint of each transaction, thereby strengthening control over decisions made and executed con
tracts as well as increasing the transparency of these procedures. The authors propose to introduce blockchain
technology into the public procurement system and determine the legal status of a smart contract to optimize
the level of data security protection of the public procurement procedure and increase their transparency and
accessibility.
