论文摘要
付款渠道网络尤其是闪电网络似乎为缺乏比特币和其他基于区块链的加密货币提供的缺乏可扩展性和隐私性提供了解决方案。先前的研究集中在闪电网络的可扩展性，可用性和加密经济学上，但是对探索其实践中获得的隐私水平的关注很少。本文通过提出几项攻击来利用有关网络的公开信息，以学习旨在保留秘密的信息，例如节点可用多少硬币，或者发件人和收件人在通过网络付款中的付款方式中，对闪电网络提供的隐私进行了详尽的分析。
Payment channel networks, and the Lightning Network in particular, seem to offer a solution to the lack of scalability and privacy offered by Bitcoin and other blockchain-based cryptocurrencies. Previous research has focused on the scalability, availability, and crypto-economics of the Lightning Network, but relatively little attention has been paid to exploring the level of privacy it achieves in practice. This paper presents a thorough analysis of the privacy offered by the Lightning Network, by presenting several attacks that exploit publicly available information about the network in order to learn information that is designed to be kept secret, such as how many coins a node has available or who the sender and recipient are in a payment routed through the network.
