Abstract

Payment channel networks (PCNs) have been designed and utilized to address the scalability challenge and throughput limitation of blockchains. It provides a high-throughput solution for blockchain-based payment systems. However, such “layer-2” blockchain solutions have their own problems: payment channels require a separate deposit for each channel of two users. Thus it significantly locks funds from users into particular channels without the flexibility of moving these funds across channels. In this paper, we proposed Aggregated Payment Channel Network (APCN), in which flexible funds are used as a per-user basis instead of a per-channel basis. To prevent users from misbehaving such as double-spending, APCN includes mechanisms that make use of hardware trusted execution environments (TEEs) to control funds, balances, and payments. The distributed routing protocol in APCN also addresses the congestion problem to further improve resource utilization. Our prototype implementation and simulation results show that APCN achieves significant improvements on transaction success ratio with low routing latency, compared to even the most advanced PCN routing.

迈向聚合支付渠道网络

支付通道网络（PCN）的设计和使用是为了解决区块链的可扩展性挑战和吞吐量限制。它为基于区块链的支付系统提供了一种高吞吐量解决方案。然而，这种 "第 2 层 "区块链解决方案也有自己的问题：支付通道要求两个用户的每个通道都有单独的存款。因此，它极大地将用户的资金锁定在特定通道中，而无法灵活地将这些资金跨通道转移。在本文中，我们提出了聚合支付通道网络（Aggregated Payment Channel Network，APCN），其中灵活的资金使用是以每个用户为基础，而不是以每个通道为基础。为防止用户出现双重消费等不当行为，APCN 包括利用硬件可信执行环境（TEE）控制资金、余额和支付的机制。APCN 中的分布式路由协议还解决了拥堵问题，进一步提高了资源利用率。我们的原型实施和仿真结果表明，与最先进的 PCN 路由相比，APCN 能够以较低的路由延迟显著提高交易成功率。

期刊介绍： The IEEE/ACM Transactions on Networking’s high-level objective is to publish high-quality, original research results derived from theoretical or experimental exploration of the area of communication/computer networking, covering all sorts of information transport networks over all sorts of physical layer technologies, both wireline (all kinds of guided media: e.g., copper, optical) and wireless (e.g., radio-frequency, acoustic (e.g., underwater), infra-red), or hybrids of these. The journal welcomes applied contributions reporting on novel experiences and experiments with actual systems.
