Couple of basic questions about Wabi I need answering;

1.Is WABI POS?

2. The current supply reads as per below, where is the rest of the total supply? How is this being distributed?
Circulating Supply
45,248,033 WABI
Total Supply
99,218,023 WABI

3. I know masternodes are planned but as far as I know there is no way they can launch them as an ERC20. They would need to launch their own mainnet first - when is that planned for and what is the protocol?
