Dragonchain is a platform, and can act as a sidechain with many many interop methods. For example, the system can checkpoint into Bitcoin (or one or more other blockchains), it can also allow you to wrap transactions or blocks into Dragonchain transactions (experimental). Standards could also be developed for such wrapping. With the checkpoint, we will provide a way to calculate risk of counterfeit and extrapolate that risk to a dollar value.
Bitcoin (or other) public addresses can also be used as a way to interoperate with other systems and parallelize tokens between the public and private networks.
