1. What Is a Full Node
A full node is a computer running blockchain software that stores the entire blockchain history and independently verifies every transaction and block against consensus rules. It is the backbone of network security and decentralization.
2. How It Works
A full node downloads and validates the full chain from genesis, re-executing or verifying all state transitions. It enforces consensus rules locally, rejects invalid blocks, and relays valid ones to peers. Full nodes serve as the source of truth for light clients and wallets, and they can broadcast transactions. Running one requires significant storage and bandwidth.
3. Why It Matters
Full nodes embody "don't trust, verify" — they let anyone independently check the network without relying on third parties. The number and diversity of full nodes determine how resistant a network is to censorship and manipulation. Their cost affects decentralization: fewer nodes means more trust in a few operators.
4. Key Facts
- Bitcoin full node: ~500+ GB of storage
- Ethereum full node: several hundred GB (with pruning, less)
- Light nodes verify only block headers and rely on full nodes
- Archive nodes store all historical state
