  A blockchain node plays a crucial role in the world of cryptocurrencies. It is essentially a computer that participates in maintaining the blockchain network. Nodes store a copy of the entire blockchain and validate transactions. They also communicate with other nodes to ensure consensus and maintain the integrity of the network. Without nodes, the blockchain network would not be decentralized and secure.
