Full Nodes vs Light Nodes

Full node:

---Stores full blockchain data.

---Participates in block validation, verifies all blocks and states.

---All states can be derived from a full node.

---Serves the network and provides data on request.

Light node:

---Stores the header chain and requests everything else.

---Can verify the validity of the data against the state roots in the block headers.

---Useful for low capacity devices, such as embedded devices or mobile phones, which can't afford to store gigabytes of blockchain data
