Smart contracts run on Codius can interact with any blockchain!
To move money in Bitcoin all you need is a valid digital signature. Smart contracts are programs that can check some conditions and then based on those decide to sign a Bitcoin (or Litecoin, Nextcoin, Ripple, etc) transaction or not based on those.

Keep the questions coming!
- drdaeman 12y agoHow? As I get it, for a software to sign something it must be in possession of private key material. Then, anyone who knows the contract could extract the key and do perform the transaction without bothering about conditions. And if only one party knows the contract, it could refuse to sign even though the conditions met. Or everything depends on a trusted third party that would keep and wouldn't disclose the secret part unless the conditions are met? And participants would only see a partial contract - i.e. conditions and actions minus the secret material?
- kelvin0 12y agoAfter reading the 'simple overview' I have exactly the same questions as you. It's all nice that the contract runs and checks for conditions and such ... however the 'implementation' of the condition checking seem to be the Achilles heal of this whole thing. For example, the use-case of the online buyer, who would check the phone was shipped? Another 'smart-contract' ...?
