Re: [Bitcoin-development] Implementing trading across chains

2013-02-13 Thread Petr Praus
Jorge, thanks for bitcoinx tip, I didn't know about it and it's certainly
related. I'll have a closer look
Regarding Ripple, I tried it but as far as I can tell, it doesn't have any
contract enforcement (by technical means) built in.

 Ripple is a concept by which people that trust each other on a network
 are able to pay with IOUs transitively. It has a new p2p
 implementation  that is still on development. The new implementation
 is very similar to bitcoin in certain senses but it has no mining.
 Bitcoin IOUs can be traded there.

 Good luck with the implementation, this is a good feature to have,
 even if it's not on the main client.

Well, if it's even possible to trade across chains with Ripple (and
I don't know of any reason shouldn't be), you will have to wait to the
release of the full node (validator) code, for now only a javascript
web client is open sourced. But it seems they at least have plans for
contracts judging from the wiki:
