Anything else we need to know

IPA proposes a system that enables cross-site attribution. The idea is to provide businesses that use advertising with a way to measure how their advertising is performing without having to rely on tracking. To do this, IPA assigns users with an identifier - a match key - that cannot be used outside of a multi-party compute (MPC) system. The MPC system only executes a specific protocol that has been vetted to ensure that it only provides aggregated information.

Hey folks, I wanted to flag that the analogous issue on the Mozilla s-p repo has been closed with a "defer" position. I won't close this for you so that you can do all the tagging and whatnot, but I think this is now obsolete and can be closed.
