Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The subject of the research is the analysis of international experience in the application of blockchain technology 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 aspects of the use of blockchain technology in public procurement systems. The methodological basis of the research includes a set of general scientific and private scientific methods, such as systemic, structuralfunctional, historical, and analysis synthesis, comparative law. The principles of transparency, fair competition, equal access for participants, and legality are outlined in regulatory legal acts regulating the field of public procurement, which in turn forms the legal basis for organizing the procurement process. To fully implement 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 contracts 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.
