What Is a Blockchain Node
Unveiling the Role of Blockchain Nodes in Decentralized NetworksBlockchain nodes play a crucial role in the functioning of decentralized networks. These nodes are essentially individual computers that are connected to a blockchain network and help to maintain the integrity and security of the system. Each node has a copy of the entire blockchain ledger, ensuring that all transactions are recorded and verified in a transparent and tamper-proof manner.
The primary functions of blockchain nodes include:
- Validating transactions by checking their accuracy and authenticity
- Propagating transactions across the network to ensure consensus
- Storing a copy of the blockchain ledger to maintain data integrity
- Executing smart contracts and other decentralized applications
