Chaumian credentials are about forty years old and still work well, provided your Issuer is willing to bear the cost of running the blind signature protocol for each credential it issues — and that the Resource doesn’t mind verifying a signature for each “show”. Protocols like PrivacyPass implement this using protocols like blind RSA signatures, so presumably these operations cost isn’t prohibitive for real-world applications. However, PrivacyPass also includes some speed optimizations for cases where the Issuer and Resource are the same entity, and these make a big difference.1
资产类别的错位： 当前的恐慌情绪更多体现在大宗商品（原油、黄金）和外汇市场的波动率上，而非美股个股的普遍性崩盘，从全球权益市场的个股来看，受沽压最严重的股份通常是那些在风险地区有业务敞口的上市公司，而宽基指数如标普500虽受科技股影响而下跌，但也被其内需型或其他科技巨头所缓冲，受地缘直接影响较小，也就是说，当前的地缘风险或尚未形成覆盖多个行业的系统性风险。
