I’m old enough to remember when credit card companies published “little books” of revoked credit card numbers. Each merchant would check to make sure the credit card number was not tampered with and not in the list in the little book of the week. Is this a scheme to compress the size of the “little book” so that the publisher could seed many copies at reasonable cost every week to avoid traffic analysis when merchants come to ask for a copy? - Adrian On Sat, May 2, 2020 at 1:11 AM Daniel Hardman <daniel.hardman@evernym.com> wrote: > Daniel wrote: >> > How is this privacy-preserving?
