A Distributed Digital Asset-Trading Platform Based on Permissioned Blockchains.

With the rapid development of cryptocurrencies, digital-asset transaction has become important, and the security and privacy of the centralized asset-trading platform are becoming serious. Distributed digital asset-trading platform has many characteristics such as high security and low transaction cost, thus received significant attention. In this paper, we first introduce distributed digital-asset-trading platforms, and evaluates currently available platforms by showing the strength and weakness of these platforms. Second, based on these analyses, we propose some principles of distributed digital-asset-trading platforms. Third, based on these principles, we put forward a novel exchange blockchain (EBC), which is based on permissioned blockchain (BC). We introduce the EBC system (EBCS), and analyse the performances of EBCS. Finally, we summarize and prospect future work of EBCS.
