2. Bitshares is off topic on this thread. PoS isn't entirely off topic since Dash's masternodes are a form of PoS (even more so in evolution since masternodes/stake will verify transactions).
That is why I included BitShares in the same table, since we concluded recently in my thread that Dash is really proof-of-stake. And BitShares and ShadowCoin are other coins attempting to add on chain protocol level anonymity. Someone else brought up ShadowCoin, so I figured I would preempt someone bringing up BitShares and not having it already in the table.
