Hi jking - I saw you also joined our slack, but I'll provide a brief response here for you as well. Since we are an asset generated on the waves blockchain, we created all 50M units in genesis and made them available for sale during our ICO period. WAVES and all WAVES assets (such as TOKES), do not subscribe to a POW mining process. You can operate a full node for waves and process transactions in a POS capacity, or you can lease your WAVES out to registered full nodes under their LPOS system. Miners today are rewarded with transaction fees in blocks, as well as with MRT (miners reward token), which was created by the waves team to incentivize full node mining. MRT will also provide an incentive to miners to process fees paid in various sub-assets, like TOKES, instead of just with WAVES fees attached. That way a person would only need to carry one asset in their wallet, should that be their preference, instead of needing to own WAVES just to make transactions in an asset like ours.
