Thanks for the correction! I don't think manifests were mentioned in the whitepaper but I found some info on the wiki: https://github.com/freenet/wiki/wiki/Simple-Manifest.

It looks like I will also have to learn more about IPFS's routing. Clearly Freenet's has some merits, and I would hope that IPFS is strictly faster since it sacrifices privacy, but I don't understand it well enough to make sense of how it scales.
