Chaum’s idea was to break the linkage between the issuance and usage of a credential. This means that when Alice shows her credential to the website, all the site learns is that Alice has been given a valid credential. The site should not learn which issuance flow produced her the credential, which means it should not learn her exact ID; and this should hold even if the website colludes with (or literally is) the issuer of the credentials. The result is that, to the website, at least, Alice’s browsing can be unlinked from her identity. Imn other words, she can “hide” within the anonymity set of all users who obtained credentials.
同时，既荒谬又吊诡的是，比尔·盖茨、乔布斯，乃至马斯克、黄仁勋，总有一个个金童像乐队指挥般，一次次挥舞起手中魔杖，随之而起的欢腾派对乐声总是不绝于耳。
