Mike Caldwell , a resident of Sandy, Utah, in the US, first introduced physical bitcoins for purchase in The eight-character code on the outside of the coin corresponds to the first eight characters of an individual bitcoin address, which is assigned specifically to that coin. The digital coin connected to each Casascius is accessible only to the person who has the private key from the physical coin. To spend a Casascius, the owner uses the code embedded into it to access the digital bitcoin online.

Peeling off the label to access the key leaves behind a tell-tale honeycomb pattern that indicates the coin has been used. Caldwell addresses that question on his FAQ page :. The holograms were made by a premier manufacturer who understands they are in the business of making tamper-evident labels, and it looks to me like they did a really good job. Caldwell has announced some other changes in pricing, batches and delivery options for his coins:.

Caldwell says he puts his own name on the line for that. He gives his word that he controls the private keys during coin manufacture — inserting them personally or supervising those who do — and asserts that he does not keep any of them. I have made it so that it if I were to perpetrate a scam, it would be possible to prove it and to hold me legally accountable — something no scammer wants to do.
