I've recently discovered Xaurum (XAUR), a unit of value on the golden blockchain that represents an increasing amount of gold and can be exchanged for it by melting.
They are buying physical gold to back all existing Xaurums, so it has growing gold base. You can read more about it on their official site http://www.xaurum.org or on bitcointalk forum thread https://bitcointalk.org/index.php?topic=1546279.0
This is the picture, someone posted on the forum, that explains Xaurum's positive inflation very well
