In this paper, we first design a variant consensus algorithm named proof of continuous work (PoCW) with a storage-related incentive mechanism. Miners can accumulate mining advantage by continuously submitting proofs of storage. Then we present a hash ring-based data allocation algorithm using the blockchain’s state. Combined with both of them, we build a reliable blockchain-based storage system without relying on any third parties.

Hands-on cybersecurity labs, Suitable for students, practitioners, and educators, 2020
The Eureka Labs are designed for learners at all levels of experience and interest in security concepts and technologies. Exploratory labs stimulate interest among learners with little or no prior experience with security techniques and concepts. Core labs allow learners to build their conceptual understanding and repertoire of security techniques through interactive experiences. Advanced labs place learners at the cutting edge of security risks associated with the latest generation network technology. We welcome and encourage feedback on each lab.
Undergraduate course, All majors, 2021
The goal of this course is to give the students a working knowledge of how to use Python to perform data analytics. We will introduce Python data structures (e.g., strings, lists, tuples, dictionaries, NumPy ndarrays, and Pandas DataFrames) and ways to manipulate data (e.g., selection, iteration, and visualization). Students will design, implement, and test Python programs.
