格利佛游记 介绍
Gulliver's Travels (1726, amended 1735), is a novel by Anglo-Irish writer and clergyman Jonathan Swift that is both a satire on human nature and a parody of the "travellers' tales" literary sub-genre It is Swift's best known full-length work, and a classic of English literature
The book became popular as soon as it was published (John Gay said in a 1726 letter to Swift that "it is universally read, from the cabinet council to the nursery); since then, it has never been out of print
The book presents itself as a simple traveller's narrative with the disingenuous title Travels into Several Remote Nations of the World, its authorship assigned only to "Lemuel Gulliver, first a surgeon, then a captain of several ships" The text is presented as a first-person narrative by the supposed author, and the name "Gulliver" appears nowhere in the book other than the title page The unabridged publications of the text begin with a fictional letter entitled "The Publisher to the Reader" and "A letter from Captain Gulliver to his cousin Sympson" which present the fact that the original account has been edited and published without the permission of Lemuel Gulliver The book proper then is divided into four parts, which are as follows
It is uncertain exactly when Swift started writing Gulliver's Travels, but some sources suggest as early as 1713 when Swift, Gay, Pope, Arbuthnot and others formed the Scriblerus Club, with the aim of satirising then-popular literary genres Swift, runs the theory, was charged with writing the memoirs of the club's imaginary author, Martinus Scriblerus It is known from Swift's correspondence that the composition proper began in 1720 with the mirror-themed parts I and II written first, Part IV next in 1723 and Part III written in 1724, but amendments were made even while Swift was writing Drapier's Letters By August 1725 the book was completed, and as Gulliver's Travels was a transparently anti-Whig satire it is likely that Swift had the manuscript copied so his handwriting could not be used as evidence if a prosecution should arise (as had happened in the case of some of his Irish pamphlets) In March 1726 Swift travelled to London to have his work published; the manuscript was secretly delivered to the publisher Benjamin Motte, who used five printing houses to speed production and avoid piracy[2] Motte, recognising a bestseller but fearing prosecution, simply cut or altered the worst offending passages (such as the descriptions of the court contests in Lilliput or the rebellion of Lindalino), added some material in defence of Queen Anne to book II, and published it anyway The first edition was released in two volumes on 26 October 1726, priced 8s 6d The book was an instant sensation and sold out its first run in less than a week
Motte published Gulliver's Travels anonymously and, as was often the way with fashionable works, several follow-ups (Memoirs of the Court of Lilliput), parodies (Two Lilliputian Odes, The first on the Famous Engine With Which Captain Gulliver extinguish'd the Palace Fire) and "keys" (Gulliver Decipher'd and Lemuel Gulliver's Travels into Several Remote Regions of the World Compendiously Methodiz'd, the second by Edmund Curll who had similarly written a "key" to Swift's Tale of a Tub in 1705) were produced over the next few years These were mostly printed anonymously (or occasionally pseudonymously) and were quickly forgotten Swift had nothing to do with any of these and specifically disavowed them in Faulkner's edition of 1735 However, Swift's friend Alexander Pope wrote a set of five Verses on Gulliver's Travels which Swift liked so much that he added them to the second edition of the book, though they are not nowadays generally included

加密货币世界中，匿名币算是比较少被提起的币种。但是在近期，韩国交易所Korbit率先下架DASH,Monero与Zcash三大匿名币，日本的Coincheck也同步执行，原因为何？

首先，我们要先了解「匿名币」与「加密货币」之间的差异。

一般加密货币与匿名币的差异

加密货币（Cryptocurrency）的重要定义有几点，「分散式系统」、「不可更改性」、「匿名性」。

分散式系统：意指资料库的存在形式是散布在世界各个角落的，这不会因为某个中央化的资料库损毁，而造成资料流失。不可更改性：代表着交易后的纪录无法被窜改，这与系统本身所特有的共识机制有关系。匿名性：代表交易的双方无法被直接辨别。

笔者又粗略将加密货币分为两类，「一般加密货币」与「匿名币」，以下介绍：

所谓「匿名」，就字面上直观解释为「不 实姓名或没有名字」，前者通常会有别称或代号，后者则什么资讯都没有。同样的，在加密货币的世界里，依照匿名的程度（匿名性），也可使货币被区分为两种，「一般加密货币」与「匿名币」：

交易上不使用真实姓名，即「一般加密货币」交易上完全不使用任何名字，即「匿名币」

第一种方式，是所谓的「半匿名」英文称为「Pseudonymous」

第二种方式，「匿名」，英文用做「Anonymous」

要解释第一种方式，「半匿名」，我们拿最具代表性的「比特币」来做事例：

比特币的起始，来自于中本聪的论文，其中，簿记账的观念呈现在整个区块链的纪录当中。白话来说，就是在比特币的交易行为中，除了交易者的真名无法取得，其他资讯都是公开的，任何人都可以追溯其交易纪录，比如交易金额、交易时间等等。这就像是你在PTT、Dcard上面有自己的帐号，乡民们可以借由IP位置发现到这个人是不是在校园中使用，但是没有人晓得帐号后面的人长什么样貌。

同理推断，「比特币」的「半匿名」特性，就像是你知道附近屋子（钱包位址）里面有多少钱、与哪些钱包在做交易、交易金额、交易次数等资讯，但是不知道屋主（拥有者）是谁。而且依照此特性，可以推断出钱包拥有者大概的轮廓。这样的「半匿名」特性，一旦有部分资讯被他人掌握的时候，便有机会藉着相关线索找到钱包拥有者。

正是这样的「半匿名」特性，让 监管「一般加密货币」的期望成为可能。所以当使用者要注册、使用加密货币交易所的时候，相关帐号都要通过要KYC（KnowYourCustomer）认证。

「半匿名」特性的好处是，交易纪录公开，并且交易的安全性与公正性由「矿工」认证完成，所以双方不得有任何异议外，如果没有任何线索可以连结钱包位址与使用者真实身份，那么「匿名性」是没问题的。但是，每个人都查得到你的钱包位址，等于有机会辨别你的实际财富状况，一旦被辨别出钱包与使用者的相关性，会产生很多现实生活中的安全性问题。想像一下，日常生活中，你会希望每笔交易都被亲朋好友知道吗？想想看你刷xyk购物之后，爸妈叫你过去跟他对帐的时候吧！

所以，「比特币」这类加密货币的匿名性，只存在于你的钱包位址并未被第三方知道、从未与法币有所连结的时候。只要知道了钱包位址，再加上KYC的帮助，就有办法找到使用者本人。

事实真的是如此吗？我们来看看区块链上的交易纪录实例：
