Cryptocurrency nodes play a key role in ensuring the functioning of decentralized networks. These nodes are devices or programs that store information about transactions and blocks, keeping the network operational. The main functions of nodes include transaction validation, block propagation, as well as checking and confirming their compliance with protocol rules.
Each node plays an important role in ensuring the transparency and security of the network, and their number directly affects the decentralization and resilience of the system. Nodes can be full, supporting the entire blockchain, or lightweight, storing only partial data. Together, they create the infrastructure that allows cryptocurrencies to operate without central control and external interference, making the system more reliable and protected from attacks.
