| dcterms.abstract | Blockchain technology was proposed in a paper, Bitcoin: A Peer-to-Peer Electronic Cash System, at 2008 and quickly became one of the most popular technologies in today. Blockchain is widely used in data storage because of its characteristics such as traceable and decentralization. Therefore, although blockchain has lots of advantages, its low query efficiency greatly affects its use. This paper proposes to build a middle layer center database to support high efficiency and flexible query. Then implement and deployed the under layer blockchain, the middle layer database and the application layer web interface. At last, this paper tested the efficiency difference between the system and the traditional blockchain client and query API. | en_US |
