VNL is completely a clone of Libcoin.You can check the source code by yourself.
He locked the thread and allows only 1 core with 1 IP in order to mine with high performance cpu (or gpu ).
This is definitely a scam without any doubt.
VNL and Libcoin are the same because libcoin is the first name of the project, it's like saying Dash is a clone of Darkcoin..
That's completely false. The dev wanted to name the project "Libcoin", but he didn't know that there was already a project started with that name.
Quote from John: "No, I named it Libcoin before I knew about libcoin, therefore the core is now called CoinPP. It is a ground up rewrite of PeerCoin and then some."
Sorry, i misunderstood then.
