论文摘要
Offchain网络提供了一个有希望的解决方案，以克服加密货币的可伸缩性挑战。但是，当今的设计权衡取舍仍未得到充分理解。特别是，离链网络通常依靠基于费用的激励措施，因此需要有效发现``好路线''：具有低费用（成本效率）的路线和交易路由的高成功率（有效性）。此外，路线发现应为机密（隐私），例如，没有透露有关谁与谁或交易价值交易的信息。本文分析了路线发现的``搜索摩擦''，即，在大规模的离chain网络中，路线发现的成本和权衡取舍，在该网络中，点头是策略性地表现的。作为一个案例研究，我们考虑了蹦床节点提供的Lighning网络和路线发现服务，在不同情况下还评估了折衷方案。最后，我们启动了针对离chain网络的替代充电方案的讨论。
Offchain networks provide a promising solution to overcome the scalability challenges of cryptocurrencies. However, design tradeoffs of offchain networks are still not well-understood today. In particular, offchain networks typically rely on fees-based incentives and hence require mechanisms for the efficient discovery of ``good routes'': routes with low fees (cost efficiency) and a high success rate of the transaction routing (effectiveness). Furthermore, the route discovery should be confidential (privacy), and e.g., not reveal information about who transacts with whom or about the transaction value. This paper provides an analysis of the ``search friction'' of route discovery, i.e., the costs and tradeoffs of route discovery in large-scale offchain networks in which nodes behave strategically. As a case study, we consider the Lighning network and the route discovery service provided by the trampoline nodes, evaluating the tradeoff in different scenarios also empirically. Finally, we initiate the discussion of alternative charging schemes for offchain networks.
