Difference between Iris & Snort?

Pardon me for an opened issue, but I really cannot get the difference. How Iris differs from Snort? I see that Iris is forked from Snort, but even the "about me"-page on Iris sends me to Snort Git-page.

_P.S. Does Snort/Iris accept Monero, Oxen or zCash for donation? How about Bitcoin (not sats)? Where are the addresses?_
