 ### Priority fee (tips) {#priority-fee}
 
-The priority fee (tip) incentivizes validators to include a transaction in the block. Without tips, validators would find it economically viable to mine empty blocks, as they would receive the same block reward. Small tips give validators a minimal incentive to include a transaction. For transactions to be preferentially executed ahead of other transactions in the same block, a higher tip can be added to try to outbid competing transactions.
+The priority fee (tip) incentivizes validators to maximise the number of transactions in a block, constrained only by the block gas limit. Without tips, a rational validator could include fewer - or even zero - transactions without any direct execution-layer or consensus-layer penalty, as staking rewards are independent of how many transactions are in a block. Additionally, tips allow users to outbid others for priority within the same block, effectively signalling urgency.
