Асиметричне шифрування в технологіях блокчейну та криптовалютах для захисту транзакцій і гаманців

Abstract

The paper examines the application of asymmetric encryption in blockchain technologies and cryptocurrencies as one of the key tools for ensuring transaction security and protecting cryptocurrency wallets. It analyzes the operating principles of asymmetric cryptography, particularly the use of key pairs (public and private), and their role in the process of digital signing, transaction verification, and safeguarding access to cryptocurrency assets. Special attention is given to the RSA and ECDSA algorithms, which are widely used in modern cryptocurrency systems. The advantages and potential vulnerabilities of this approach are identified in the context of decentralized networks.
