I measured the scanning performance on Cake, and estimated 2 years of scanning would take around 9 hours.
Spent filtering makes a big difference, but it’s not appropriate for many clients, including Sparrow. Also the BIP approach requires non trivial data download which means making assumptions about bandwidth.
That said there are use cases for the BIP approach, and I’m glad Dana is working on them!
