BLOCKCHAIN AND ITS APPLICATION IN THE DEFENCE SECTOR

The digital transformation of the economy affects many sectors, including the defence sector, which is sensitive from both a national and international perspective. The digitalisation of the economy is based on technologies such as robotics, autonomy, additive manufacturing technologies (3D printing), augmented reality, big data, quantum computers, artificial intelligence and blockchains. In this article, we will take a closer look at the latter, namely blockchain technology. We will briefly outline its main properties and advantages, which make it particularly attractive for use in the defence sector, and dwell on its application to implement such a tool as smart contracts. One of the key advantages of blockchain in the context of military operations is ensuring transparency and traceability of supplies. In today's realities, logistical problems can cost lives, but blockchain helps prevent fraud and improve coordination between interacting communication nodes. Thanks to the use of blockchain technologies, each unit of supply can be recorded in an immutable register, which allows you to track its path from sender to recipient. This reduces the risk of loss or theft, and simplifies the process of monitoring and verifying the accuracy of information about deliveries. In addition, the decentralised nature of the blockchain enhances the security of military communications, protecting them from interception and attack. Each message is encrypted in such a way that it can only be read by the addressee. This ensures a high level of confidentiality and data protection, as information transmitted through the blockchain is distributed among numerous network nodes, making it difficult for attackers to access. By using cryptographic methods, the blockchain ensures that even in the event of a successful attack, attackers will not be able to alter or falsify information. Creating a tamper-proof ID system will help fight counterfeiting and improve the process of identifying wounded or fallen soldiers. By assigning unique and unchangeable authenticators to personnel, equipment or weapons, one hundred per cent identification of military entities can be ensured. This allows for accurate tracking of the movement and status of each soldier and equipment, which contributes to more efficient resource management. This system also increases the level of trust in the information provided, as it is recorded in the blockchain and cannot be changed or deleted. The introduction of blockchain technology in the defence sector can bring significant benefits, including increased security, transparency and efficiency. However, this process is accompanied by numerous challenges and risks that need to be considered and overcome for successful integration.
