In the DAG in the transaction cost, each project has its own idea. Trade, there is no charge in IOTA, because the project party believes that when a user to create and publish their unit at the same time, has made confirmation for previous two units, equivalent to contribute their strength. In Byteball, transaction costs created by the first confirm new unit charge customers. Our idea is to release unit need to pay fees, just not the same with Byteball charge way.
DAG architecture, the creation of a new unit and release is to actually have release unit before confirmation. Existing DAG project needs to be done before release unit of simple work proof (PoW), to some extent prevent witch attack and prevent abuse of the network. We will use here we proposed contribution certificate (PoC, will detail in a later chapter). Transaction costs will be to first confirm 6 nodes, linearly decreasing, users pay the total fees associated with the size of the user release unit. The aim is to encourage more nodes stored more units, and effectively control the width of the network.
In one word,CyberVein token is similar to Ethererum‘token，it’ s a certificate to pay Transaction Fees in CyberVein system.
