Node Scheduling: A Blockchain-Based Node Selection Approach on Sapiens Chain

摘要

Recently, blockchain techniques have been widely used in finance, e-commerce and sharing economy, owing to its decentralization, openness and permission-less properties. In cybersecurity, a blockchain-based framework Sapiens Chain is proposed, which aims to provide decentralized and trustable cybersecurity services while protecting the privacy of the anonymous users. However, how to select an optimal service provider in Sapiens Chain remains challenging. In this paper, we tackle the novel problem of scheduling nodes in Sapiens Chain, which covers and rewards the nodes based on their performance with the history of providing cybersecurity services, and thus attracting more and more users to anticipate cybersecurity services. Under the scheduling algorithm, we propose to select nodes for different tasks by unifying the interest of each user, such as the bandwidth, the computing resource, and the activation degree. The experimental results demonstrate the efficiency and effectiveness of our method.
