How does bitrot protection actually work?
I understand the concept, but am curious how it is actually implemented on 6.2.0

BTRFS generates the checksums on writes, and verifies them on reads. This feature is built into BTRFS itself.
Netgear's protection algorithm is their own, and they aren't saying much about how it works, other than what I said above. It's a unique feature for Netgear, and my guess is that they want to keep it that way.
There is a similar bitrot protection being built into BTRFS (using a raid-like mode that is integrated into the file system). But that raid-like mode is still experimental, and OS6 is using traditional software raid instead.
