The Vibe: A computer that helps run and secure a blockchain network.
The Details: Nodes store a full copy of the blockchain ledger, validate transactions, and share data with other nodes. Some nodes just verify (light nodes), while full nodes keep everything and enforce rules. Thousands of nodes worldwide make the network decentralized—no single point of control or failure.
Pro Tip: Anyone can run a node (great for privacy and supporting the network)—Bitcoin and Ethereum have easy setups. Use a block explorer if you don’t want to run one yourself.
