论文摘要
加密货币正在迅速找到在实时总和解和付款等领域的应用。 Ripple是一种加密货币,在银行和付款提供商中获得了突出。它通过其波纹协议共识算法(RPCA)解决了拜占庭将军的问题,其中每个服务器都维护一个服务器列表,称为唯一节点列表(UNL),该列表代表该服务器的网络,并且不会集体欺骗它。服务器认为,当UNL上的服务器在交易上达成共识时,网络已经达成共识。 在本文中,我们改善了涟漪,以达到更好的速度,安全性和最后一英里连接性。我们实施有关弹性,鲁棒性,提高安全性和有效信息传播(IP)的指南。我们增强了系统,以确保每个服务器从整个网络中接收信息,而不是从UNL成员接收信息。我们介绍了UNL重叠的范式作为IP的函数以及服务器分配给其自己的UNL的信任。我们的设计使识别和减轻一些恶意行为是可能的,包括试图欺诈性地花费或拖延系统的尝试。我们提供了实验证据,证明了我们方法比当前的连锁方案的好处。我们观察到$ \ geq 99.67 \%$减少了双重支出攻击和审查的机会,$ 1.71倍的容错增加到$ \ geq 34.21 \%$ $ $ $ $ \%$ \ geq QUQ 4.97 x $和$ 98.22X $加速和成功率和$ $ $ \ geq 3.16x $ \ geq的成功率。共识分别。
Cryptocurrencies are rapidly finding application in areas such as Real Time Gross Settlements and Payments. Ripple is a cryptocurrency that has gained prominence with banks and payment providers. It solves the Byzantine General's Problem with its Ripple Protocol Consensus Algorithm (RPCA), where each server maintains a list of servers, called the Unique Node List (UNL), that represents the network for that server and will not collectively defraud it. The server believes that the network has come to a consensus when servers on the UNL come to a consensus on a transaction. In this paper we improve Ripple to achieve better speed, security and last mile connectivity. We implement guidelines for resilience, robustness, improved security, and efficient information propagation (IP). We enhance the system to ensure that each server receives information from across the whole network rather than just from the UNL members. We introduce the paradigm of UNL overlap as a function of IP and the trust a server assigns to its own UNL. Our design makes it possible to identify and mitigate some malicious behaviours including attempts to fraudulently Double Spend or stall the system. We provide experimental evidence of the benefits of our approach over the current Ripple scheme. We observe $\geq 99.67\%$ reduction in opportunities for double spend attacks and censorship, $1.71x$ increase in fault tolerance to $\geq 34.21\%$ malicious nodes, $\geq 4.97x$ and $98.22x$ speedup and success rate for IP respectively, and $\geq 3.16x$ and $51.70x$ speedup and success rate in consensus respectively.
