This scientific thesis analyzes the security aspects of blockchain technology, particularly the major threats arising in decentralized networks and the methods for mitigating them. During the research, the impacts of 51% attacks, Sybil attacks, Double Spending, smart contract vulnerabilities, issues related to cryptographic keys, and DDoS attacks on blockchain infrastructure were examined. In addition, the role of Proof-of-Work, Proof-of-Stake, Multi-signature mechanisms, encryption algorithms, and audit mechanisms in ensuring security was analyzed based on scientific sources. The research results demonstrate that although blockchain technology possesses a high level of security capabilities, threats to security still remain due to human factors and software vulnerabilities.References
