论文摘要
比特币是使用区块链技术的第一个也是最广泛的分散电子加密货币系统。它使用点对点（P2P）网络在没有中央权限的情况下运行并传播系统信息，例如交易或区块链更新。参与节点之间的通信高度依赖于基础网络基础架构来促进平台。了解同伴形成策略，同伴列表和延迟的影响对于了解节点通信的节点至关重要。为此，我们通过测试台进行了一项有关比特币交易特征的广泛研究。分析表明，同伴选择策略会影响交易的传播和确认时间。此外，当比特币中的默认距离选择策略在较高的到达强度时的性能较小，并创建高数字叉。
Bitcoin is the first and the most extensive decentralized electronic cryptocurrency system that uses blockchain technology. It uses a peer-to-peer (P2P) network to operate without a central authority and propagate system information such as transactions or blockchain updates. The communication between participating nodes is highly relying on the underlying network infrastructure to facilitate a platform. Understanding the impact of peer formation strategies, peer list, and delay are vital on understanding node to node communication. To this aim, we performed an extensive study on the transaction characteristic of Bitcoin through a Testbed. The analysis shows that peer selection strategies affect the transactions propagation and confirmation time. Moreover, the default distance-based peer selection strategy in Bitcoin performs less when there is high arrival intensity and creates high number forks.
