Peer to peer - how does it work in the context of cryptocurrencies?
The principle of P2P network operation is quite simple and is based on an even simpler method of data exchange. These can be - horrifyingly - multimedia files and documents, but also cryptocurrencies. How does this whole system work and why is it the basic "accounting book" of the cryptocurrency market?
Nodes, nodes and peer to peer
Peer to peer network is divided - to put it simply - into two types of its users. The first of these are computers that act as clients, that is, computers that receive data from the network. The second group includes computers acting as servers that send data to specific clients. Each of the P2P users acts as a node that can receive or send data. And that would basically be all about the structure of these networks.
The advantage of P2P is the availability of selected data in a kind of "digital cloud", from which data can be downloaded or sent at any time. A user acting as a client can send data as a server to another client practically at the same time. An important advantage of P2P is high resistance to signal fading. In the event of an unexpected loss of connection, data transfer can begin from where the connection was lost.
P2P and cryptocurrencies
Peer to peer plays a huge role in cryptocurrencies. "Electronic cash" can be transferred without any limitations between individual network users. Blockchain is therefore a kind of accounting ledger within which all transactions are made. This means no central servers, clearing institutions etc.
In a P2P network, nodes store a copy of the blockchain and compare it with their copies that are owned by other nodes. Thanks to this, you can easily verify that all transactions are carried out correctly.
Summary
The use of a P2P system for the execution of foreign exchange transactions not only improves the settlement process, but also facilitates their verification. In case of any doubts, the transaction is immediately rejected.
