RBAC-GL: A Role-Based Access Control Gasless Architecture of Consortium Blockchain

摘要

Blockchain-based decentralized applications (DApps) have been used in various industrial areas. More are more companies are willing to participate in blockchain technology. Notheisen [18] proposed a framework based on Ethereum [3] to trade lemons on the blockchain platform. In this work, we discuss the application aims to digitize valued assets in the commercial area, such as real estate and watches. This article introduces a general DApp framework and some standard attack methods in the beginning. Our proposed novel role-based access control (RBAC) model improves the system permission control, and gasless mechanism enhances security and reliability. It allows users to publish their assets and use cryptocurrency to trade online. Meanwhile, this work can prevent several categories of attacks, such as gas-related attacks and malicious API invokes, according to our improvements. Besides, the efficiency performance of the system remains the same as before.
