  Nodes play a crucial role in the validation and verification of cryptocurrency transactions. They are essentially computers or devices that participate in maintaining the blockchain network. Each node stores a copy of the entire blockchain and continuously communicates with other nodes to ensure consensus on the validity of transactions. By verifying the accuracy and legitimacy of transactions, nodes help prevent double-spending and ensure the integrity of the blockchain. Without nodes, the decentralized nature of cryptocurrencies would not be possible.
