论文摘要

在本文中,我们提出了一种在分散信用网络中重新平衡链接权重的技术。信用网络是基于对等信任的网络,与传统的银行电汇转移相比,可以快速且廉价的跨货币交易实现,这导致了它们的普及和使用的日益增长。尽管研究人员研究了此类网络用户的交易和隐私安全性,并投入了大量精力来设计有效的信用网络路由算法,但在{补充}网络中用户的信用联系领域的工作相对较少。定期在信用网络中补充链接对于保持用户溶剂,网络具有足够的流动性并防止交易失败很重要。这是通过称为{Rebalancing}的过程来实现的,该过程使资金不足的用户能够创建传入和即将发出的信用链接。我们提出了一个系统,其中零或没有链接权重的用户可以在我们称为{ballace Transfer}的过程中与现有的,受信任的用户创建传入的链接,然后创建指向现有或新用户的链接,该链接希望加入网络,我们调用{bailout}的过程。这两个过程共同构成了我们提出的重新平衡机制。我们的技术还将通过为用户提供较低的利率来提高网络的竞争力,并使用户能够通过参与高通量交易路径来赚取基于路由费的收入。

In this paper, we propose a technique for rebalancing link weights in decentralized credit networks. Credit networks are peer-to-peer trust-based networks that enable fast and inexpensive cross-currency transactions compared to traditional bank wire transfers, which has led to their increasing popularity and use. Although researchers have studied security of transactions and privacy of users of such networks, and have invested significant efforts into designing efficient routing algorithms for credit networks, comparatively little work has been done in the area of {replenishing} credit links of users in the network. Replenishing links at regular intervals in a credit network is important to keep users solvent, the network viable with enough liquidity, and to prevent transaction failures. This is achieved by a process called {rebalancing} that enables a poorly funded user to create incoming as well as outgoing credit links. We propose a system where a user with zero or no link weights can create incoming links with existing, trusted users in the network, in a procedure we call {balance transfer}, followed by creating outgoing links to existing or new users that would like to join the network, a process we call {bailout}. Both these processes together constitute our proposed rebalancing mechanism. Our techniques would also serve to make the network more competitive by offering users lower rates of interest, and enable users to earn routing fees-based revenue by participating in high throughput transaction paths.
