In the context of the increasingly diversified blockchain technology, interoperability among heterogeneous blockchains has become key to further advancing this field. Existing cross-chain technologies, while facilitating data and asset exchange between different blockchains to some extent, have exposed issues such as insufficient security, low efficiency, and inconsistent standards. Consequently, these issues give rise to significant obstacles in terms of both scalability and seamless communication among blockchains within a multi-chain framework. To address this, this paper proposes an efficient method for cross-chain interaction in a multi-chain environment. Building upon the traditional sidechain model, this method employs smart contracts and hash time-locked contracts (HTLCs) to design a cross-chain interaction scheme. This approach decentralizes the execution of locking, verifying, and unlocking stages in cross-chain transactions, effectively avoiding centralization risks associated with third-party entities in the process. It also greatly enhances the efficiency of fund transfers between the main chain and sidechains, while ensuring the security of cross-chain transactions to some extent. Additionally, this paper innovatively proposes a cross-chain data interaction strategy. Through smart contracts on the main chain, data from sidechains can be uploaded, verified, and stored on the main chain, achieving convenient and efficient cross-chain data sharing. The contribution of this paper is the development of a decentralized protocol that coordinates the execution of cross-chain interactions without the need to trust external parties, thereby reducing the risk of centralization and enhancing security. Experimental results validate the effectiveness of our solution in increasing transaction security and efficiency, with significant improvements over existing models. Our experiments emphasize the system's ability to handle a variety of transaction scenarios with improved throughput and reduced latency, highlighting the practical applicability and scalability of our approach.
在区块链技术日益多样化的背景下，异构区块链之间的互操作性已成为推动该领域进一步发展的关键。现有的跨链技术虽然在一定程度上促进了不同区块链之间的数据和资产交换，但也暴露出安全性不足、效率低下和标准不一致等问题。因此，这些问题在多链框架内的区块链扩展性和无缝通信方面都造成了重大障碍。为了解决这一问题，本文提出了一种在多链环境中进行跨链交互的有效方法。该方法基于传统的侧链模型，采用智能合约和哈希时间锁定合约（HTLC）来设计跨链交互方案。这种方法将跨链交易中的锁定、验证和解锁阶段的执行进行去中心化，有效避免了过程中与第三方实体相关的中心化风险。它还大大提高了主链和侧链之间资金转移的效率，同时在一定程度上确保了跨链交易的安全性。此外，本文创新性地提出了一种跨链数据交互策略。通过主链上的智能合约，可以将侧链的数据上传、验证并存储在主链上，实现便捷高效的跨链数据共享。本文的贡献在于开发了一种去中心化协议，该协议能够协调跨链交互的执行，而无需信任外部方，从而降低了中心化风险并增强了安全性。实验结果验证了我们的解决方案在提高交易安全性和效率方面的有效性，与现有模型相比有显著改进。我们的实验强调了该系统能够以更高的吞吐量和更低的延迟处理各种交易场景的能力，突出了我们方法的实际适用性和可扩展性。
