While creating the infrastructure Casper API we have ensured that providers, investors and users of the platform will have convenient system of calculations. CST token is the project's own monetary unit.
CST tokens are a means of payment for storage and CDN: users are charged, and suppliers are rewarded for providing storage and CDN services.
Casper API will also be launched on several blockchain platforms with smart contracts. Thus, for example, a supplier will receive storage orders from users from several blockchain platforms at the same time. For the simplicity and clarity of the calculations of the supplier and users of various blockchain platforms, the supplier will be rewarded in CST.
For transparency of transactions and operations we use a smart contract, it simplifies the communication of customers with suppliers. It keeps the register of service providers, connects them with consumers, carries out billing. The smart contract also regulates the storage network by monitoring compliance with the working conditions of storage service.
