Blockchain technology offers significant opportunities for data protection, including decentralization, immutability, and security. However, its drawbacks, such as scalability issues and high energy consumption, require careful analysis. For effective use of blockchain in the field of data protection, it is essential to consider both its advantages and limitations. In this article, we examine the drawbacks of blockchain technology, with a particular focus on the scalability issue. We will analyze various approaches to solving this problem and thoroughly discuss the proposed solutions. Additionally, attention will be given to the concept of multidimensional blockchain and its structural features. In conclusion, we will present formulas and methods aimed at increasing transaction speed, which will help to better understand how multidimensional blockchains can serve as an effective solution for scalability.
