Re: [EMC] EmerCoin — Innovative blockchain services! ( PoW&PoS - SHA-256)
I thought the "not a super detailed response" explanation by craslovell was excellent 
Merge mining allows Bitcoin miners to simultaneously mine Emercoin with their mining equipment. So a 51% attacker now needs to control 51% of much larger hashing power, whereas before they would only need to control 51% of the hashing power that had been dedicated only to Emercoin. And on top of it, an attacker also needs to own a huge amount of emc, due to Proof-of-Stake.
So, the combination of Proof-of-Stake with merged mined PoW should make EMC blockchain very difficult to reverse with the conventional 51% type of blockchain attacks.

I like how it builds up in regards to security. Blockchain technologies are secure by design, but "secure" should develop with the technological development. I think, EMC is ahead of the current situation. That is why it could explode to the moon when environment gets mature enough to adapt it.
The technology is already here on the Emer blockchain. Now with a little luck perhaps Poloniex will consider the addition of an EMC/BTC market after their announcement of 17 other coin markets being dropped.
This is something fans/users of Emercoin have been requesting for a long time. It is not a necessity since there are several other reliable exchanges to trade Emercoin however I'm sure it would be warmly received by the public.
