As blockchain technology continues to evolve, it has fostered an extensive ecosystem of applications and platforms. This dynamic landscape is characterized by a myriad of innovative solutions, ranging from decentralized finance and supply chain management to digital identity and voting systems, each contributing to the ongoing advancement and adoption of blockchain technology across various sectors. Achieving interoperability among these applications and platforms poses a significant challenge due to their use of distinct protocols, and remains a bottleneck hindering the widespread adoption of blockchain technologies. Addressing this challenge requires designing a universal interoperability protocol while ensuring compliance with the security and privacy constraints specific to each blockchain, thus adding complexity. We propose an agnostic interoperability protocol designed for seamless asset movement across independent private blockchain networks, regardless of their individual protocols. This protocol leverages incentive-driven smart contract and Zero-Knowledge Proofs to establish a decentralized, secure, and privacy-focused framework for interoperability. We conduct a security analysis using game theory and provide both theoretical and empirical evaluations of the protocol end-to-end delay. Through a comprehensive use case, we demonstrate the secure deployment of the proposed protocol for asset movement between two private blockchains. We also discuss the trade-offs between cost and delay in cross-blockchain transactions. Furthermore, a comparative analysis with existing interoperability schemes showcases the proposed interoperability scheme superiority in terms of robustness, privacy preservation, and verifiability.

用于无缝资产移动的不可知且安全的互操作性协议


随着区块链技术的不断发展，它培育了广泛的应用程序和平台生态系统。这种动态景观的特点是无数的创新解决方案，从去中心化金融和供应链管理到数字身份和投票系统，每一个都有助于区块链技术在各个领域的不断进步和采用。由于这些应用程序和平台使用不同的协议，实现这些应用程序和平台之间的互操作性构成了重大挑战，并且仍然是阻碍区块链技术广泛采用的瓶颈。应对这一挑战需要设计一个通用的互操作性协议，同时确保遵守每个区块链特定的安全和隐私约束，从而增加了复杂性。我们提出了一种不可知的互操作性协议，旨在实现跨独立私有区块链网络的无缝资产移动，无论其各自的协议如何。该协议利用激励驱动的智能合约和零知识证明来建立一个去中心化、安全和注重隐私的互操作性框架。我们使用博弈论进行安全分析，并提供协议端到端延迟的理论和实证评估。通过一个全面的用例，我们演示了所提出的两个私有区块链之间资产移动协议的安全部署。我们还讨论了跨区块链交易的成本和延迟之间的权衡。此外，与现有互操作性方案的比较分析展示了所提出的互操作性方案在鲁棒性、隐私保护和可验证性方面的优越性。
