@sg - thank you for your message and congratulations on the fund raise! There has been admittedly a bit of confusion in the way we got described in the press. We do not consider ourselves Plasma. In my humble opinion Plasma is a very specific thing which includes a Plasma operator that operates an UTXO chain as well as a set of exit algorithms that are executed if the Plasma operator becomes malicious.
At Skale we are building a network of ETH-compatible side chains that use fast PoS-like consensus. Miners will be able to add servers to our network and stake Skale tokens to make money. Out of this large network of servers we will be able to build side-chains on demand by randomly picking servers, and then rotating them from time to time. A dapp developer will be able to pay in Skale tokens and get a side chain for her application.
Nowadays for some people (including investors) Plasma is more of a generic term everything that speeds up transactions 
If they want to keep calling us Plasma, we do not really argue too much … ))
