论文摘要
本文介绍了Adamastor，这是一种新的低潜伏期和可扩展的分散匿名支付系统，它是RING机密交易（RINGCT）的扩展，与使用授权证明的股权证明（DPOS）兼容，该算法兼容，作为防御攻击的防御机制。 Adamastor还包括一种新的诱饵选择算法（DSA），它可以具有独立的兴趣，称为SimpleDSA，这是协议的关键方面，该协议使用环签名将发件人匿名化。 SimpleDSA提供了防止同质性攻击和链分析的安全性。此外，它可以修剪支出的产出，解决了通常与此类方案相关的永久产出增长问题。使用自称的共识算法对Adamastor进行了实施和评估，与基于工作证明的加密货币相比，延迟的潜伏期明显较低。 Adamastor还具有足够的可扩展性，使其适用于分散和匿名的支付网络。
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.
