Lots of Copies Keeps Stuff Safe
https://www.lockss.org/ https://www.lockss.org/
This is a brilliant system relying on a randomised consensus protocol. I wanted to do my info sec dissertation on it, but its security model is extremely well thought out. There wasn't anything I felt I could add to it.

- MattPalmer1086 2y agoThat was actually one of the key constraints in the LOCKSS system, since it was designed to be run by libraries that don't have big budgets. The design is really very good.
- ChadNauseam 2y agoI wish IPFS wasn't so wasteful with respect to storage. I tried pinning a 200mb PDF on IPFS and doing so ended up taking almost a gigabyte of disk space altogether. It's also relatively slow. However its implementation of global deduplication is super cool – it means that I can host 5 pages and you can host 50, and any overlap between them means we can both help one another keep them available even if we don't know about one another beforehand. For a large-scale archival project, it might not be ideal. Maybe something based on erasure coding would be better. Do you know how LOCKSS compares?

I just tried it myself with a 257mb PDF (as reported by `ls -lrth`) and doesn't seem to add that much overhead: $ du -sh ~/.ipfs 84K /home/user/.ipfs $ ipfs add ~/Downloads/large\ PDF\ File.pdf added QmSvbEgCuRNZpkKyQm6nA5vz5RTHW1nxb6MJdR4cZUrnDj large PDF File.pdf 256.58 MiB / 256.58 MiB [============] 100.00% $ du -sh ~/.ipfs 264M /home/user/.ipfs
