I wrote up a basic timing test on [this branch](https://github.com/SarangNoether/monero/tree/view-tag) to examine the time savings from view tags and compare to the current scan functionality. Here's a plot showing the...

To be clear, the linked code does not assume anything about transaction structure, and only examines outputs as separate discrete units with their own key derivation computations. Plot data was...

Here is some simple [example code](https://github.com/SarangNoether/skunkworks/tree/clsag/clsag) that shows how this might work with both full and simple transaction types.

Thanks @apoelstra for looking this over. Comments regarding the notes: 1. We're working on a writeup with security proofs! 2. The commitments are currently the source of a few questions...
