Abstract

This article introduces a method of hiding transaction amounts in the strongly decentralized anonymous cryptocurrency Monero. Similar to Bitcoin, Monero is a cryptocurrency which is distributed through a proof-of-work “mining” process having no central party or trusted setup. The original Monero protocol was based on CryptoNote, which uses ring signatures and one-time keys to hide the destination and origin of transactions. Recently the technique of using a commitment scheme to hide the amount of a transaction has been discussed and implemented by Bitcoin Core developer Gregory Maxwell. In this article, a new type of ring signature, A Multilayered Linkable Spontaneous Anonymous Group signature is described which allows one to include a Pedersen Commitment in a ring signature. This construction results in a digital currency with hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation. The author would like to note that early drafts of this were publicized in the Monero Community and on the #bitcoin-wizards IRC channel. Blockchain hashed drafts are available showing that this work was started in Summer 2015, and completed in early October 2015. An eprint is also available at http://eprint.iacr.org/2015/1098 .
保密交易
本文介绍了一种在强去中心化匿名加密货币门罗币中隐藏交易金额的方法。与比特币类似,门罗币是一种加密货币,通过工作量证明“挖掘”过程进行分发,没有中央方或可信的设置。最初的门罗币协议是基于CryptoNote的,它使用环签名和一次性密钥来隐藏交易的目的地和起源。最近,比特币核心开发者Gregory Maxwell讨论并实现了使用承诺方案来隐藏交易金额的技术。本文描述了一种新的环签名——多层可链接自发匿名组签名,它允许在环签名中包含Pedersen承诺。这种结构产生了一种数字货币,其交易金额、来源和目的地都是隐藏的,具有合理的效率和可验证的、无需信任的代币生成。作者想指出的是,该草案的早期草案在门罗币社区和#bitcoin-wizards IRC频道上公布。区块链散列草稿显示,这项工作于2015年夏季开始,并于2015年10月初完成。电子打印版也可在http://eprint.iacr.org/2015/1098上获得。
