It’s a completely different backend model; as far as I know alipay works just like PayPal where transactions are fully “internal” - the buyer pays Ant Group and the seller cashes out at a later date.

UPI is a real inter-organization payment system more akin to credit card processing, where fund requests flow from the payer, through a payer processor, through a merchant processor, and finally to their end destination, and the actual reconciliation happens through a bank transfer system. It’s a much less centralized system.
