A MODEL OF A DISTRIBUTED STORAGE SYSTEM FOR PRIVATE KEYS OF CRYPTO WALLETS
M. R. Salihov ITMO University
Annotation: With the development of Web3 technologies, the third generation of the Internet has become one of the most promising areas. It involves the use of decentralized, transparent and user-oriented applications. However, many Web3 projects do not pay due attention to security, which can lead to serious consequences. Even a small error in the code can make the system vulnerable, opening access to intruders. Because of this, the industry faces frequent security breaches that threaten users and undermine trust in new technologies. One of the main problems of Web3 is the management of private keys. This is a critical aspect of security, which is directly related to the protection of digital assets and personal information of users. The risk of loss or theft of the private key can lead to irreparable consequences, since in case of loss there is no way to restore or reset the key. This article discusses various ways to store the private key of a cryptographic wallet to ensure security. For example, a key can be divided into parts and stored encrypted on hardware media, or the whole encrypted key can be stored on secure media. Quantitative data were calculated using Shamir’s scheme.
