/ipfs/ - interplanetary file system

>You need someone to actually host real storage.
anyone who want can host it
some threads or images will be dead but it's part of the fun I think

You can have nodes deprecate content in sync or pseudo-sync as part of site rules, whether a node agrees or not is up to them and if they don't they end up acting as archives.
Everyone in the network eventually ends up able to host part of the content because of bitswap so there's not even a need for an ipfschan-specific network of people or anything.

weak, still connects to 4cdn for stuff

how have you done it?

httrack --depth=2 --ext-depth=1 -c8 --disable-security-limits --max-rate=0 'boards.4channel.org/g/thread/69660869'
it's a bit overkill, for example, it grabs the front page of every board, because the page links to them all, but it's set like that so it can grab the full images, resulting in a rather complete copy

thank you

Stuff a 1-2U box full of drives, apply FreeBSD+ZFS or DragonFly+HAMMER2 or Linux+ZFS/BtrFS/bcachefs, and colocate it. Add an init service for the IPFS daemon and a cron job to pin content from the chan's front page. Done.
