Could somebody explain how vouchers work?
Here's a real use example:
due to my intent to expose the blockchain data from this transaction, I decided to use an address from ChipMixer. The address was obtained using ChipMixer voucher codes that I set aside for this potential purpose in November. I always keep a moderate amount of money in Chip vouchers, just in case I need to do something bad for my privacy. The money for these vouchers may have been deposited by me anytime in about the past three or four years; thus, any blockchain observer who identifies Chip inputs will not find it feasible to guess which were mine.
