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

You may have encountered keyboards with an optional lift at the back of the board, raising the top keys higher than the space bar. Every set of hands is different, but for most people, pulling the backs of the hands towards the forearms increases strain. Negative tilt has the opposite effect by sloping in the other direction, lowering the top number keys while raising the edge with the spacebar. Many Alice and some split keyboards offer an optional negative tilt. I found it was more comfortable to enable that feature when I’m standing, and I preferred to have the keys flat when sat at my desk.。搜狗输入法2026对此有专业解读
