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.
DIGIX DAO TOKENS. Our vision for the future is a world operating on Smart Contracts. Indeed, we think this vision will become a reality very soon. In this world, a stable store of value is needed - that's why we created DGX. In order to ensure the success of DGX, we also conceived DGD; a stake in a 'Distributed Autonomous Organisation' that rewards DGD holders based on DGX's success. By participating in the DAO and working on its behalf in curating proposals, you get rewarded based on the usage of DGX in the Ethereum ecosystem. DGD holders use their tokens to decide on proposals, and determine the best way forward for Digix.
