A running node is a computer that actively participates in a blockchain network by maintaining a copy of the entire blockchain and validating transactions. Nodes communicate with each other to share data and ensure that all participants have an accurate and up-to-date version of the blockchain.These nodes help in securing the network by verifying new transactions and checking that they follow the established rules. When a new transaction is proposed, running nodes verify that the sender has sufficient balance and that the transaction adheres to the protocol’s guidelines.Running a node can also contribute to the decentralization of the network, as it distributes control and prevents any single entity from having too much influence. By running a node, users typically help maintain the integrity and security of the blockchain while also being able to access and use the network more efficiently. This can be particularly important in systems where trust and transparency are essential, ensuring that all transactions are accurately processed and recorded.
