Besides using CMK tokens to utilize the on-chain model result oracle, users will be able to use a varied set of currencies such as ETH, USDT, USDC, etc. Those alternative currencies will incur a higher cost, but will provide an easy method of integration with existing web3 applications and not create an artificial barrier of entry. Any of these tokens that are used in place of CMK will be used to buy CMK afterwards, thereby stimulating demand while simplifying UX.
