摘要

摘要: 支付通道网络作为区块链的扩容手段受到广泛关注.其中，影响支付通道跨链路由选择的主要因素包括路径距离、节点手续费报价等，现有工作主要针对上述某个因素之一展开深入研究.定义了节点质量综合评价函数，包括节点手续费报价、路径距离和历史信誉等多个因素，设计了多因素反向Vickrey拍卖(multi-factor reverse auction, MFRA)的路由方案，以实现跨链支付路由过程中，对候选中继节点质量的综合选择.建立了候选节点的等价报价函数，用于将节点质量中的非价格属性因素转化为价格属性，并引入了以2为基数的指数机制实现对等效投标价格的差分隐私，保障参与节点的报价不被泄露.安全性分析和性能评估表明，MFRA路由方案在降低节点手续费开销的同时，可以有效保障交易参与节点的报价隐私，实现快速高效的多跳跨链支付.

Abstract: Payment channel networks have received widespread attention as an important means of scaling blockchains. Among them, the main factors affecting the selection of payment channel cross-blockchain routing include path distance, node fee quotation, etc. The existing work mainly conducts in-depth research on one of the above factors. A comprehensive evaluation function of node quality is defined, including multiple factors such as node fee quotation, path distance and historical reputation. We design a routing scheme for multi-factor reverse Vickrey auction (MFRA) to achieve a comprehensive selection of the quality of candidate intermediate nodes in the process of cross-blockchain payment routing. The MFRA routing scheme establishes the equivalent bidding function of candidate nodes, which is used to convert non-price attribute factors of node quality into price attributes. In the MFRA routing scheme, we introduce the based-2 exponential mechanism to achieve differential privacy for the equivalent bid price, which ensures the quotation anti-leak of participating nodes in the auction routing process. The security analysis and performance evaluation show that the MFRA routing scheme can effectively protect the quotation privacy of transaction participating nodes while reducing the node fee overhead, and realize efficient multi-hop cross-blockchain payment.
