Full nodes play a crucial role in the Bitcoin network as they validate transactions and blocks, enforce the consensus rules, and relay this information to other nodes on the network. They help ensure the security and integrity of the network by independently verifying all transactions and blocks they receive.
On the other hand, miners are responsible for creating new blocks through the process of mining, which involves solving complex mathematical puzzles to add new transactions to the blockchain and secure the network. Miners are incentivized with block rewards and transaction fees for their work in securing the network.
In summary, full nodes validate and relay transactions and blocks, while miners create new blocks_
