Abstract
The article is devoted to reviewing the concept of blockchain in the implementation of a decentralized money transfer system. The concept of fault tolerance of cryptocurrency technology is considered and some aspects of the fault tolerance solution are given. The analysis of information security of enterprises was carried out. The questions of anonymity of banking systems are touched upon. The dependence of the anonymity of the banking system on the quality of the software and on the security policy is shown. Recommendations are given for solving the problem of anonymity, in particular, generating a private key or embedding an algorithm for connecting transactions. Approaches to creating transactions are considered. Examples of algorithms that allow protecting user transactions are given. The description of the blockchain structure and the consensus algorithm has been carried out. The issues of generating a chain of blocks of an honest user and a chain of blocks of an attacker are considered. Formalization of the estimate of the probability of transaction break-even has been carried out. Binomial random walk was used for estimation. The end of the transaction process is just as justified as waiting for new blocks to be added to the chain of an honest user. A digital signature is used to identify whether a transaction belongs to a public key. The processes of signing a transaction and verifying a signature are considered. Separately, the approaches used in the design of cryptocurrencies are highlighted. The network stores the entire history of transactions, it is possible to calculate the balance of the total amount of incoming funds and spending money. These approaches are software solutions based on game theory and cryptography. The main attention is drawn to the business values of cryptocurrencies and ways to achieve them. As a result, the necessary functionality of the software client is formulated. The article provides a thorough analysis of a new financial and settlement instrument - electronic money. The task of developing a virtual payment system has recently received much attention.
