What Is a Bitcoin Node? Full Nodes, Light Nodes, and Miner Nodes Explained
How has the Bitcoin network never gone down in 15 years? The answer is a P2P network made of tens of thousands of independent nodes. Starting from the division of labor among full nodes, light nodes (SPV), and miner nodes — their validation mechanisms and economic incentives — this article systematically unpacks Bitcoin's decentralized network architecture, explains why more nodes means a more secure network, and how an ordinary person can run their own full node. Suited to readers who want to deeply understand Bitcoin's underlying operating logic; worth bookmarking.
