On July 17th, 2015, bitsig.io was created by Daniel Routman and Josh Ortwein on the simple idea that any text or document can be timestamped on the Bitcoin blockchain by sending a small amount of bitcoin to a brainwallet.  The text or document can be used as the passphrase for the brainwallet, and can be of any length or size.
