What is a Node?
In the context of telecommunications and software engineering, a “node” typically denotes a larger interconnected network component. However, in the realm of cryptocurrencies, a node represents a fundamental element responsible for executing a blockchain’s algorithm to validate and verify transactions.
Nodes are integral to every blockchain, typically existing as computer systems that store a copy of a blockchain’s core protocol and complete transaction history. With the decentralized nature of blockchain technology, individuals have the freedom to operate nodes from anywhere globally, as long as they maintain connectivity to the decentralized network and possess the necessary resources.
What are nodes used for?
Nodes play a crucial role in blockchain networks as they can generate, transmit, and receive blockchain data. Their main functions include validating, recording, and broadcasting transactions across the network. Nodes ensure the proper functioning of the blockchain by verifying transactions and rejecting any malicious activity. Additionally, they execute the consensus mechanism of the blockchain, which confirms and validates transactions. The two prevalent consensus mechanisms are proof-of-work (PoW) and proof-of-stake (PoS).
