A node in the crypto world refers to a computer or a device connected to a blockchain network, acting as a communication point between the network and other nodes.
The node is responsible for verifying transactions, verifying blocks, and ensuring the network runs smoothly. There are different types of nodes, including full nodes, light nodes, miner nodes, and supernodes.
Full nodes have a complete copy of the blockchain, while light nodes only have a limited version of the blockchain. Miner nodes process transactions and validate blocks, while supernodes have the most resources and perform various functions to support the network.
In summary, nodes play a crucial role in the functioning and security of blockchain networks, making sure the network runs efficiently and accurately.
