The rapid development of Artificial IntelligenceGenerated Content (AIGC) has brought daunting challenges regarding service latency, security, and trustworthiness. Recently, researchers presented the edge AIGC paradigm, effectively optimize the service latency by distributing AIGC services to edge devices. However, AIGC products are still unprotected and vulnerable to tampering and plagiarization. Moreover, as a kind of online non-fungible digital property, the free circulation of AIGC products is hindered by the lack of trustworthiness in open networks. In this article, for the first time, we present a blockchain-empowered framework to manage the lifecycle of edge AIGC products. Specifically, leveraging fraud proof, we first propose a protocol to protect the ownership and copyright of AIGC, called Proof-of-AIGC. Then, we design an incentive mechanism to guarantee the legitimate and timely executions of the funds-AIGC ownership exchanges among anonymous users. Furthermore, we build a multi-weight subjective logic-based reputation scheme, with which AIGC producers can determine which edge service provider is trustworthy and reliable to handle their services. Through numerical results, the superiority of the proposed approach is demonstrated. Last but not least, we discuss important open directions for further research.

翻译：人工智能生成内容（AIGC）的快速发展给服务延迟、安全性和可信性带来了严峻挑战。近期，研究人员提出了边缘AIGC范式，通过将AIGC服务分发至边缘设备，有效优化了服务延迟。然而，AIGC产品仍缺乏保护，易遭受篡改和抄袭。此外，作为一种在线非同质化数字资产，AIGC产品在开放网络中因缺乏可信性而难以自由流通。本文首次提出一种区块链赋能的框架，用于管理边缘AIGC产品的全生命周期。具体而言，我们首先利用欺诈证明提出一种名为"Proof-of-AIGC"的协议，以保护AIGC的所有权与版权；其次，设计了一种激励机制，保障匿名用户间资金与AIGC所有权交换的合法性与时效性；最后，构建了基于多权重主观逻辑的信誉机制，使AIGC生产者能够甄别可信可靠的服务提供商。数值结果验证了所提方法的优越性。最后但同样重要的是，我们探讨了值得进一步研究的重要开放方向。
