Hi Hive account@bengy thanks for the feedback. The idea is to use a printer that prints concealed labels, with a program that automatically generates private keys for the printer and erases its memory afterwards. Physical Bitcoin services usually work on a trust basis, with few people having access to the private keys. We want no one to have access except the person who is unpeeling the label. We'll share as much about the process as possible so you can make sure it's trustworthy.
