The concept and nature of peer-to-peer networks are analyzed, a short history of their development is researched and presented. The first network of this type (Usenet), its features and prerequisites are described. Three types of peer-to-peer network architectures are considered – pure, federal and hybrid; advantages and disadvantages of each. The hybrid architecture is the most widely used today, as using a central server to connect nodes is a promising approach. Three generations of peer-to-peer networks are considered and their architectural features are presented. The first generation involved only file sharing, its feature was the use of a central server, which had information about which node contains which file. The second generation was characterized by the absence of a central server, but there was no indexing of nodes and data, which caused long delays in finding a node to connect. The third generation is more advanced, because it provides storage in each node of hash tables with information about other network members. The main advantages and disadvantages of peer-to-peer network architectures are investigated. A comparative analysis of peer-to-peer and multi-peer networks is performed. It is determined that it is more expedient to use decentralized networks in comparison with centralized ones, especially in cases where anonymity, confidentiality, fault tolerance and scalability are a priority. The most known directions of practical use of peer-to-peer networks are investigated. Today they are used in chat systems, banks, cryptocurrency systems, video communication systems. Decentralized systems are also used when working with digital wallets, because it makes online payments more effective.
