SPV mining

Simple payment verification (SPV) nodes are designed only to track the state of the blockchain and verify that certain transactions are included in blocks. They don't download most block bodies, only their headers

SPV nodes are not intended for use in blockchain mining. They can't validate the transactions included iin their blocks

SPV miners trade transactions fees for increased probability of block rewards. They create blocks that only contain the transaction paying them the block reward. Not including other transactions means no chance of a double-spent transaction. Not needing to validate blocks gives the SPV miner a head start on mining
