Adamastor: a New Low Latency and Scalable Decentralized Anonymous Payment System

Rui Morais, Paul Crocker, Simao Melo de Sousa

AI总结:

本研究提出新型去中心化匿名支付系统Adamastor,作为RingCT的扩展兼容DPoS共识,搭配可抗攻击、支持输出剪枝的SimpleDSA算法,经Narwhal共识验证,延迟低于PoW类加密货币且可扩展性良好。

摘要:

本文提出Adamastor——一种新型低延迟可扩展去中心化匿名支付系统,它是环机密交易(Ring Confidential Transactions,RingCT)的扩展,兼容采用委托权益证明(Delegated Proof of Stake,DPoS)作为女巫攻击防御机制的共识算法。Adamastor还包含一种可独立应用的新型诱饵选择算法(Decoy Selection Algorithm,DSA),名为SimpleDSA,这是使用环签名隐匿发送方身份的协议的核心组成部分。SimpleDSA可抵御同质化攻击和链分析,还支持对已花费输出进行剪枝,解决了此类方案普遍存在的输出永久增长问题。研究基于Narwhal共识算法实现并评估了Adamastor,结果显示其延迟远低于基于工作量证明的加密货币,且具备充足的可扩展性,适用于去中心化匿名支付网络。

英文摘要:

This paper presents Adamastor, a new low latency and scalable decentralized anonymous payment system, which is an extension of Ring Confidential Transactions (RingCT) that is compatible with consensus algorithms that use Delegated Proof of Stake (DPoS) as a defense mechanism against Sybil attacks. Adamastor also includes a new Decoy Selection Algorithm (DSA) that can be of independent interest, called SimpleDSA, a crucial aspect of protocols that use ring signatures to anonymize the sender. SimpleDSA offers security against homogeneity attacks and chain analysis. Moreover, it enables the pruning of spent outputs, addressing the issue of perpetual output growth commonly associated with such schemes. Adamastor is implemented and evaluated using the Narwhal consensus algorithm, demonstrating significantly lower latency compared to Proof of Work based cryptocurrencies. Adamastor also exhibits ample scalability, making it suitable for a decentralized and anonymous payment network.
