A peer to peer networks that consists of a bunch of computers participating in a blockchain network. So there is no central controlling node or something.
A network can be public (anyone can participate like in the Ethereum blockchain), private (permissioned) or hybrid.
Types of nodes:
- Miner; Create new blocks by collecting transactions posted on the blockchain network, checking them, construct a new block and post that on the network. In many blockchains miner receive a reward for being the first one to construct a new block.
- Full node; Checking block validity using all transactions and blocks.
- Lightweight node; Checking chain integrity using only the block headers.
In a private network you don't need mining, you can just appoint one or more nodes that can create new blocks.
