摘要：This work is motivated by a phenomenon in the cryptocurrency market. With the increasing price of Ethereum (ETH), the transaction cost of online activities becomes more and more expensive, which discourage the use of  transactions supported by ETH. The same problem happens to other cryptocurrency based on “virtual machine” blockchain. In this paper, we propose a dual coin system and a decentralised exchange market, where we will introduce a utility coin to pay the transaction cost. The utility coin will be generated by the main coin, and can be traded in a tailor-made decentralised market. With our design, the transaction cost will be depressed when the main coin inflates, and investors will be encouraged to use the blockchain when the transaction cost is high.
