【Abstract】The number of people surfing over the e-commerce has reached to 1.6 billion, while the transaction scale has approached to 2,304 billion dollars at the end of 2017. No doubt that the security and efficiency of an e-payment system have attracted lots of attention in the field of e-commerce. That is the reason why the blockchain technique has been widely spread to most of the e-commerce mechanisms. A blockchain employment can be used to guarantee the properties of decentralization and non-tampering, which provide users a more stable and reliable trading process and prevent malicious behaviors, including double-spending and sybil attack. Nevertheless, the overhead of each transaction process is too heavy to realize immediate transaction. In this study, we aim to speed up the performance of transaction through an asynchronous dual blockchain. Moreover, we have exploited the reputation mechanism to reduce resource consumption. The new method has inherited the security from a blockchain technique. Specifically, the experimental results have demonstrated that the asynchronous dual block-chain is fairly safe and efficient.
