The separate payment and consolidation have to pay for 51% more block weight to be mined than the Payjoin. What other scaling solution achieves that kind of savings?
 
 ## Opportunistic Consolidation
-Payjoin got its start as a way to make a sort of coinjoin from a payment. A receiver combines their input with the sender's, effectively joining a [consolidation](https://bitcoin.stackexchange.com/questions/103194/confused-about-utxo-management-and-consolidation) transaction with a simple transfer. An observer looking at the Payjoin is cannot tell it apart from a simple transfer where all of the inputs come from the same entity.

 ## Transaction Cut-Through
 Payjoin not only creates opportunity to batch consolidation, but may create any output with the incoming funds. Because Payjoin involves live interaction, the receiver may [open lightning channels](./lightning), forward funds to a different wallet, pay for goods and services, or batch forward transactions with incoming funds without first taking them into a new UTXO.
