Subject: Re: [Bitcoin-development] Implementing trading across chains
Precedence: list

Hi, you may be interested in a couple of related projects.

Colored coins uses satoshis to represent smart property, shares, IOUs
of another currency...Colored coins can be atomically traded for
bitcoin. If you implement the trade across chains contract they would
also be tradeable for another chain currencies like namecoin or
freicoin.

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.
