论文摘要
比特币P2P网络是客户之间所有通信的核心。该网络的可到达部分已经通过大量研究探索和分析。但是，在大多数情况下，无法到达的节点被忽略了。但是，它们是网络的相关部分，并且在消息传播中起着至关重要的作用。在本文中，我们专注于交易传播，并表明增加无法达到的节点的参与可以潜在地提高网络的鲁棒性和效率。为此，我们建议对网络协议进行一些更改。此外，我们设计了一种新颖的交易传播协议，该协议明确涉及无法到达的节点，以更好地保护脱姓式攻击。我们的解决方案易于实施，并且可以有效地为比特币网络带来直接的好处。
The Bitcoin P2P network is at the core of all communications between clients. The reachable part of this network has been explored and analyzed by numerous studies. Unreachable nodes, however, are, in most part, overlooked. Nonetheless, they are a relevant part of the network and play an essential role in the propagation of messages. In this paper, we focus on transaction propagation and show that increasing the participation of unreachable nodes can potentially improve the robustness and efficiency of the network. In order to do that, we propose a few changes to the network protocol. Additionally, we design a novel transaction propagation protocol that explicitly involves unreachable nodes to provide better protection against deanonymization attacks. Our solutions are simple to implement and can effectively bring immediate benefits to the Bitcoin network.
