Node is equipment and various devices connected to the Bitcoin or other cryptocurrency system.

The technical architecture of the digital coin system is unique. It differs from any other format for receiving and transmitting data, especially from the electronic fiat money system.

Experienced miners, traders, developers, and other market participants in the cryptocurrency community know what Node is. By definition, nodes are points designed to create data and transmit and receive it to different users. Simply put, such nodes ensure the stable operation of blockchains, in which open-source information is publicly available to all community members.

Kinds

Node classification is carried out based on the tasks that the node performs.

Full - synchronized with the network, it stores a copy of the complete information from the blockchain, namely:

• transaction data;
• information about all other entries, including changes and updates.

Machines that perform the functions of complete units operate for at least 6 hours daily. Thanks to them, the high speed of data verification and transactions, an appropriate level of security, and the stability of the entire network are maintained because these nodes are its basis.

Lightweight Nodes are not independent elements. The response is usually directly related to the data provided by the miners. Therefore, it is much easier to mislead such system participants by manipulating information to accept invalid blocks or transactions.
