From the archived bitcointalk announcement:

◥◣ Prototanium 119◥◣


Creator
HagbardCeline

Algorithm
SHA-256 (Merge Mine Tech)

Description
Prototanium is a main-net storage vault that is 100% compatible with the Un testnet chain. 
It is based entirely on the 0.10.x branch of Unobtanium but supports syncing and using the testnet chain of Un instead of its own blockchain! 
auxpow enabled - can be merge mined, and yes it is a Nerd toy.

To use Prototanium's feature in UNO simply run unobtaniumd with the `-prototanium` flag
