Are there any ready-made open source projects for implementing a currency exchange?

What I want is a currency exchange with low fees and minimal barriers to entry (preferably worldwide but for starters just in the eurozone), but didn't find one. Why? There must be some marketplace software around...

Guess I'll have to implement my own one then. Can't be that hard. Making it bulletproof might be another thing...

I think the intersango code is opensourced?

I also started a data model for an exchange, but especially in the eurozone, I see a lot of legal issues with an exchange,  >:(

Thanks for the pointer! Indeed there seems to be something here: http://gitorious.org/intersango/intersango Though the last commits are from September 2011. (I though Intersango is defunct? There doesn't seem to be any way to actually get into the site.)

Can you elaborate on some the legal issues? From what I've read, the eurozone/SEPA area seems like a heaven compared to the regulations that US exchanges are facing.

Running an exchange here (Germany) means, that you are practically a bank. You have to report monthly, have to hire someone just to check for money laundering and there are more regulations like these.

Dark Exchange Revived?

I wouldn't touch that code... It has a history of losing people money...

I'm willing to help with the data model and with the code, as I said.

Shouldn't be the exchange only..

The whole integrative concept has to embrace
the derivatives as well: futures and options contracts
as long as derivatives have profound impact on the spot market..

A single decentralized p2p market in onionland or i2p..

Will crowdfunding model be successful for that?

There is a reason no decentralized p2p market in tor or i2p has been start, that is way too anonymous for a site like this. You want to know who you are sending huge amounts of money too and if something happens someone can fix it.

I've been under impression that bitcoin is a self-organizing financial ecosystem
with roots traced to cryptoanarchy, that alone implies privacy as top priority,
where human control has been deliberately removed by design, in order to prevent abuse
and which possesses some properties of an AI or collective intelligence at least..

yes... so what is your point? i was talking about sending fiat to convert to bitcoins...

Ohhh, i meant trading.

Thanks Xenius, that link is a gold mine. I'll have to start digging.

The "Dark Exchange" idea is intriguing, but the idea seems very vague and difficult to implement. The trust issue seems very tricky to solve, if you don't provide an escrow system of some kind - and then you already have a central authority. Unless the network would let you find trustworthy peers who could act as an escrow agent (who would naturally collect a fee for their services). And you could collect higher fees by voluntarily giving up your privacy (if your identity can be traced to a real person, less incentive to run with the money).

Yeah, it could be doable. But perhaps the time is not ready for one yet.

I'd love to talk about some of the technical issues - I've been thinking quite a bit about inner workings of exchanges lately - and I'm sure it would benefit others, too. I wonder if the Development forum is the right place for that?

Let us know, if you start a thread there. I'd have to enter the model into ArgoUML again, before I could post an image of the data model.

I am working on an open-source exchange. It has not been tested thoroughly yet.

It is a very simple exchange, all in python. Probably can not handle more than a few thousand users. I took a different strategy on security, I think that it is WAY simpler this way, and there is much less risk.

Please take a look at it, and tell me what you think.

This looks interesting.  Can you tell me more about it, show me pictures (screenshots), etc.?  I've hung out at mcxNOW and think his software is pretty interesting (word is he's going to v2.5 soon).  It got me interested in trying to get an exchange going myself, but one that is as bullet-proof as possible, with customer investment protection as priority #1.  If customers don't feel their money is safe, they are far less likely to invest, period.  Why have an exchange nobody feels they can trust?

Can I run this software on my own computer(s) at home (i.e. it's all self-contained, no 3rd party hosting elsewhere)?  Do I need to change my Cox Internet account to something business-oriented, if I do this?

Agorism yet to check, looks interesting :D

Yeah there are a lot of legal issues.

The WWC team  (https://bitcointalk.org/index.php?topic=612306.msg6773761#msg6773761) is offering 1 Million WWC + 3 BTC for a turnkey Altcoin exchange web site / software.
The exchange is to handle only 2 currencies at the beginning: BTC and WWC (a la mintpal), and then eventually expand to include FIAT currencies (a la Mtgox / Coinbase).
We are U.S.-based and can handle regulatory requirements (license for money transfers)

blinktrade.com
and of course, you also have exchanges such as NXT AE and CounterParty

Thanks for info.
On Blinktrade.com, when you click on "Signup" or "Apply here", a new browser window opens and closes immediatey. Can't be my popup blocker... ???

NXT AE and CounterParty are a good starting point for a platform developer. Because we are a bunch of lazy people, we are really looking for a turnkey solution and are willing to pay 3 BTC (worth 50p) + 1 Million WWC (worth about US$1000).

You could try http://www.bex.io/
Basically they control the exchange/coin handling securely, you provide the licensing and regulatory part. It's backend programmed in Erlang for excellent concurrency and they are an IRL business that likely has insurance (obv you would perform due diligence to confirm this). I wouldn't trust any old exchange software lying around, there's just too many things that need taking care of like built in stop trade measures, security to  make sure nobody can inject phony payment into their accounts and buy coins with nothing, proper password hashing ect. ect.

No idea what they currently charge or what the profit sharing scheme is.

WOW... 30 BTC starting bid price. And I thought 3 BTC was generous! :)

Im just now reading this because Im going to make a quick little (a FAKE [NOT REAL]) exchange site. and let me tell you that this comment here is the best:



Jesus christ i dont want to swear but you are fucking disrespectful 3 BIT COINS for a TRADING CRYPTO GRAPHIC COIN EXCHANGE ?

Closed source is at best a virus, but yet here we are, history repeats itself and the script kiddies run out with names like ITGeniusGuru offering 3bit coins.. eventually they will get what they want.. heck if your offer is still up PLEASE PM me i will do this for your shit offer, return you a working product, and then laugh as you maintain it.

Do not expect software to replace humans, unless they are the lazy ones.

if you develop market placed exchange equal poloniex bitrex ce-cex yobit and more
but you not understand programing not understand security your web is danger
your all money and customer client can lost hack

There are no reliable out-of-the-box solution for you I'm afraid. I wouldn't recommend you to use ANY open source engines.
