Node
Definition
A node is any computer that runs a blockchain's software and participates in the network. Full nodes (like Bitcoin Core) download and validate the entire blockchain — they are the backbone of decentralization. Light clients only download block headers and rely on full nodes for validation. The more independent nodes, the more decentralized and censorship-resistant the network. Anyone can run a Bitcoin or Ethereum node from home.
Why Does This Matter?
Understanding Node is essential for anyone investing in cryptocurrencies or working with blockchain technology. This concept directly influences how projects are valued, how markets behave, and what risks and opportunities exist for investors.
