The principle behind T.OS is the establishment of a commercial payment system that utilizes digital currency. This will be the first such system in the history of the world. The solution comprises two coins. The TOS coin, or TOSC, is a regular cryptocurrency coin, which is not used for commerce, but can be exchanged on regular exchanges to any other digital currency. Its value may appreciate or depreciate and that is why it can't be used for commerce.
Plutons are digital tokens issued to users on the Ethereum blockchain, these are native to the Plutus app. To provide an analogy, these tokens are similar to cash back or frequent flier miles. As a user, you will automatically be rewarded with a 3%* rebate in Plutons for every Bitcoin deposit you make towards a purchase. Plutons can be used within the Plutus app in the same way as Bitcoins. This means that you can use Plutons to charge your contactless balance just as you would with BTC, with the added benefit of zero fees and instant conversions.
