Based on Private Keys Each Opendime holds one private key. It publishes the public key (payment address) to anyone and never reveals the key until "unsealed".

Piggy-Bank Economics !? Yes. It's like a piggy-bank. You must destroy it to spend the funds. At first that seems expensive and wasteful, but it's a key part of our security model: you can trust a sealed Opendime, and it's obvious when it's been opened.
