What is Full Node?
Crypto Glossary Definition
A node which downloads a full copy of the blockchain and helps validate it, among other things (such as store a memory pool of pending transactions). Different blockchain implementations may have nodes serve different purposes. Someone who runs a node should not be confused with a miner.
Why Full Node Matters
Running a full node means downloading and independently verifying the entire blockchain yourself, rather than trusting someone else's copy of it. It's the mechanism that makes a blockchain's rules enforceable by the community rather than by any single company or miner.
