Dont wanna be annoying, but I found this comment under the one of Factom videos.
"Here's another easier way to secure the integrity of 29,000 books.
Create a torrent for each book, or a torrent that contains all the books, keep the .torrent, you'll have SHA1 hashes for each torrent, and you'll have the file pieces hashed as well. A .torrent file is a Factum used to validate the integrity of files transfered.
Then grab the .torrent hash and put it into a Bitcoin transaction.
You can create torrents of just about any data source, and add those torrent infohashes to the Bitcoin blockchain.
I still don't see why Factum is needed."
Can someone elaborate? Im not techie, but I guess simple solutions always win.
Bittorrent does everything Factom does
and allows for efficient filesharing, and is much more distributed/resilient
I regularly backup archives of ebooks and music by creating torrents of them and using that to distribute data + hashes across lots of storage
