What are Cypher Stamps?

Cypher stamps are stamps that are loaded with actual digital bitcoin issued by Cypher Postage.

      What you see are two QR codes, to the left is the public address that can be scanned to reveal the amount of bitcoin loaded on the coin.

      The right side QR code is the BIP38 encrypted private key that once scanned will allow you to sweep the bitcoin from the stamp, that is, if you have the correct password.

      The passwords on these stamps are at least 17 scrambled letters numbers and figures that according to https://password.kaspersky.com/ will take centuries to solve.

      Not to fear, inside the envelope these stamps come on is a full print out of the password along with all pertinent information for the keys for this stamp.

   As of today, 3rd November 2021, Cypher stamps are the only stamps in the world that are loaded with Bitcoin and also the only stamps that have a smart contract timelock feature.
