We've been brainstorming a market / assets exchange and ways of going about implementation. Since GH doesn't operate the wallet service in the classic way (eq no wallets with user funds) we need to come up with a method that allows users to trade P2P without the need for an escrow or assets / payments being processed through GetHashing (as it would be the case with a classic crypto exchange). So the best approach would be be a double deposit smart contracting interface to support direct P2P two-party escrow but, it would have to be color aware.
We're a currently a little ahead of our time with the smart assets. It will take some time for either us to develop a trustless P2P market interface or one "evolving" around the intrawebs.
I still have the auctioning software we could utilize in the interim if there is a demand for it. It would allow members to also list their hardware, other coins or basically anything else and also has a wanted ads section. The software can be seen in action at http://www.blackauctions.eu/index.php
The site already has a custom BTC payment gateway and I guess we could customize it further to support the use of additional coins and payments are P2P instead of going through the website. We can also easily add BitHalo (for example) as an "offline" payment option which could than be used by the seller and buyer to complete the auction using a smart contract.
If there is interest by the community to put it to use we can re-brand it and move it to the GH servers.
In time, no rush. I enjoy GHcloud interface. Really nice work. Thanks to you
Thank you for being a part of it
