Dark Exchange: a 100% decentralized p2p exchange

[jtimon]

It may be possible to do atomic transactions with purely digital currencies. I don't think it would be possible with fiat. Either way, you can still use Dark Exchange with these methods. It's just not integrated in any meaningful way.

No, my proposal it's only for bitcoin-like currencies, not even LR or dwolla.
It probably could be integrated with dark exchange in the same client.

It would be nice to have checkboxes instead of the current one-choice form for the transfer manner

I've added a couple issues for this:

https://github.com/macourtney/Dark-Exchange/issues/36

and

https://github.com/macourtney/Dark-Exchange/issues/37

These were common suggestions from other people as well. I'll make them higher priority.

Did you make sure I2P is running properly? You can do that through your browser using the link: http://127.0.0.1:7657/index.jsp

somehow I missed that dependency.. i now see 3 peers so I guess I am good.. looks like a cool project.

[joulesbeef]

wow i was the last post here? is this a dead project? still only 3 peers and no bids or asks

[markm]

I got i2p running, then got sidetracked, then lately started to realise i2p hasn't been running since several reboots ago and I'm not even sure anymore where I was when I ran it. Then happily came across your post, reminding me that i2p wasn't an end in itself but a dependency of dark exchange...

Likely to be some days before I actually end up having it running though I think. Thanks for the reminder.

lol sounds sorta familiar....i had just noticed i2p runing.. then it reminded me of darkexchange but took me forever to remember the name and find it on my system again.

No, the project is not dead. I plan to release another version this weekend.

Since there are so few nodes on the network right now, the best way to find bids is to view identities on the identity tab. I have around 10 open offers, and I try to run Dark Exchange 24/7.

[joulesbeef]

cool i had just restarted it.. so perhaps it hadnt downloaded everything.. i was mainly bumping your thread trying to get some response.. good to see it is still in development.

I've released version 1.2.0 of Dark Exchange. You can download it from here:

https://github.com/macourtney/Dark-Exchange/downloads

There are a bunch of changes in this release, but it's been a long day and I don't have the energy to list all of the changes right now. I'll do it tomorrow.

If you must know now, you can check out the git commit logs.

[morpheus]

New features in the 1.2.0 release of Dark Exchange:

Issue #4: Trades are now highlighted when they have an unread message.
Issue #5: Trades are now highlighted when an action is required.
Issue #31: Removed all id columns from the tables to free some space.
Issue #32: Added a show only online identities check box to the identities tab.
Issue #33: The password field starts with focus when the login window is first displayed.
Issue #34: Timestamps added to all logs.
Issues #38, #39, #40, #41, #42: Added support for Paypal, Liberty Reserve, Paxum, Pecunix and Namecoin.

Fixes:

Added exception handling to keep bad data from dropping your client off the network (big issue fixed).
Fixed a display issue on the peer tab which caused the "is notified" column to display a 1 instead of yes.
Dark Exchange is more aggressive at finding other nodes on the network.

The run.sh does not work whether I am in its directroy with it or up in the main project directory when I run it, it claims it cannot find the class.

lein run from the main directroy does run it, but once I put my username and password and repeat of password to create a user it says

Which looks like it crashed, but, it doesn't return to the commandline prompt so maybe that is not a fatal error and I now am to wait however long it might take for the i2p network to establish connections and tell everyone about this new user I created or something?

Or is it simply in some kind of loop or just waiting for that thread to finish which actually is never going to finish having in fact crashed?

Should I leave it overnight and see if it has finished making the new user in a few hours? Or just kill it as broken?

Wouldn't Freenet be more suitable for hosting a decentralized thing that must be pretty much unshutdownable?

[jtimon]

Ey, morpheus. It seems that atomic trades between chains are possible.
Unlike LRusd/btc, btc/nmc trades could be atomic, so there would be no risk at all to trade using dark exchange for these trades.

I think this feature would be awesome.

The way Dark Exchange is built right now, it is not possible to really integrate an exchange like that. Really, all you can do with Dark Exchange is find other people with offers. How you go about trading it between you and your partner.

If the above type of trades become popular, I will certainly look into integrating it.

How does one go about resetting or recovering a password if one forgot it?

One step at a time I guess. I'm not even sure that those trades are possible right now, but it seems that the protocol wouldn't have to chain, only a client or an extension will be needed. I'll wait to see what Mike puts in the wiki though.

Unfortunately, it's lost.

The password is saved locally to your machine (encrypted of course). That way, there is no single point of failure which would allow a hacker to take over the exchange. The disadvantage is, no one can help you recover your password if you forget it.

You can just create a new user.

Watching this.

Also, awesome idea.

[Sultan]

This seems like such an interesting idea and I am looking forward to seeing it develop. I don't quite understand how it works, though.  Could somebody please explain to me the mwchanisms of the exchange and how a decentralised architecture makes it work?

Thanks.
