Abstract

As blockchain technology advances, cross-chain asset transfer has become a critical issue in achieving interoperability between different blockchain networks. However, existing cross-chain solutions often require high trust requirements and complex communication protocols, which hinder usability and flexibility. To address these issues, this work introduces the temporary relay, a novel cross-chain asset transfer model without continuous blockchain network presence and frequent inter-chain communication. Technically, the temporary relay uses non-interactive zero-knowledge proofs to verify transactions and protect privacy while ensuring blockchain immutability and traceability after the temporary relay is shut down. We detail the construction of the temporary relay and analyze the security of the circuits constructed by the zero-knowledge proofs. Prototype implementation on the Substrate blockchain platform and experimental evaluation demonstrate the feasibility of the temporary relay. Furthermore, the verification time of zero-knowledge proofs in our model is short.

临时中继：更灵活的跨链方式

随着区块链技术的发展，跨链资产转移已成为实现不同区块链网络之间互操作性的关键问题。然而，现有的跨链解决方案往往需要较高的信任要求和复杂的通信协议，这阻碍了其可用性和灵活性。为了解决这些问题，这项工作引入了临时中继，这是一种新型的跨链资产转移模式，无需持续的区块链网络存在和频繁的链间通信。在技术上，临时中继使用非交互式零知识证明来验证交易和保护隐私，同时确保临时中继关闭后区块链的不可篡改性和可追溯性。我们详细介绍了临时中继的构造，并分析了零知识证明所构建电路的安全性。在 Substrate 区块链平台上的原型实现和实验评估证明了临时中继的可行性。此外，在我们的模型中，零知识证明的验证时间很短。

期刊介绍： The aim of the Peer-to-Peer Networking and Applications journal is to disseminate state-of-the-art research and development results in this rapidly growing research area, to facilitate the deployment of P2P networking and applications, and to bring together the academic and industry communities, with the goal of fostering interaction to promote further research interests and activities, thus enabling new P2P applications and services. The journal not only addresses research topics related to networking and communications theory, but also considers the standardization, economic, and engineering aspects of P2P technologies, and their impacts on software engineering, computer engineering, networked communication, and security. The journal serves as a forum for tackling the technical problems arising from both file sharing and media streaming applications. It also includes state-of-the-art technologies in the P2P security domain. Peer-to-Peer Networking and Applications publishes regular papers, tutorials and review papers, case studies, and correspondence from the research, development, and standardization communities. Papers addressing system, application, and service issues are encouraged.
