Abstract
A physical cryptocurrency may comprise a physical medium and an attached processor. The processor may generate a public-private key pair, or the public-private key pair may be generated in a secure and auditable manner external to the processor and stored on the processor. The private key may enable execution of a smart contract on a blockchain to transfer an asset from a starting address to a destination address on the blockchain.

- and
- a communications system for transmitting and receiving data from a remote computing device, wherein the communication system is configured to transmit the signed digital challenge to the remote computing device.
