Abstract: This article explores the possibilities of using blockchain technology in police work. Examples of the use of blockchain in various areas of police activity, such as personal data management, control of drug trafficking and other prohibited substances, traffic monitoring and the fight against cybercrime, are considered. The authors note that thanks to the storage of data in the blockchain, it becomes possible to increase the protection of the confidentiality of personal information, ensure transparency and efficiency of police work, as well as prevent fraud and corruption. The conclusion of the article emphasizes that the use of blockchain can improve the work of the police and ensure greater security of citizens.   Distributed ledger technology, or blockchain as a service (BaaS) is indeed a relatively new product on the market that allows you to provide blockchain services for corporate clients. This solution allows you to use more reliable and secure methods of data processing and transaction management within the organization.
All these economic effects can lead to a reduction in costs and an increase in the efficiency of the police.
In general, the use of blockchain technology in the police can have a number of advantages, such as increasing transparency and accountability, reducing data processing time and combating data falsification. However, it is necessary to take into account some risks, such as the possibility of data privacy violations, as well as difficulties in integrating with existing systems and training personnel. In general, the introduction of blockchain technology into the police requires careful analysis and an approach that takes into account all aspects of the use of technology and its impact on the organization.
