【Abstract】Since the ancient times, there exist all kinds of criminals in the world. In order to punish them, most authorities usually encourage the people to provide the evidence of a crime. To avoid the revenges from the criminals, it is necessary to study the anonymous reporting scheme with anonymous rewarding. In this paper, for the first time, we propose the novel concept of blockchain-based anonymous reporting scheme with anonymous rewarding (BB2AR). Our BB2AR scheme solves the open problem: how to realize the anonymous reporting and the anonymous rewarding simultaneously? First, we formalize the system model, definition, and security model of BB2AR. Second, we propose a concrete BB2AR scheme based on the elliptic curve public key cryptography. Our formal proof shows that our BB2AR scheme satisfies the anonymous reporting and the anonymous rewarding simultaneously. Finally, we analyze its efficiency and provide its prototype implementation. From the comparison, our BB2AR scheme is more efficient and practical.
