Dark Exchange: a 100% decentralized p2p exchange

[jtimon]

Interesting thread about USDcoins earlier. Basically a crypto coin pegged to the dollar right?

Yes. Someone (say mtgox) backs them. The concept is basically the same as BeerTokens.

I talked about a chain where issuance of different crypto-currencies (or crypto IOUs if you prefer) by users is allowed.
It's probably outdated. And I have concerns about scalability and DoS attacks (spaming and such).

In this other thread, a chain is not needed, but still usd IOUs can be issued by users and traded for bitcoins atomically.

I'm thinking lately about combining both things so I should review both threads properly.

[phelix]

usdCoin miners? A different chain? Why? Just "taint" satoshis, no need to create another chain, that's much more complicated.

What's the problem with a new chain?
Another currency, another chain.
I don't think it's more complicated, the issuers can just use the beertoken code and change the name and backing of the currency.

It would be great to be able to trade ripple credits for bitcoins. But to make the trades atomic and decentralized you need:

1) Decentralized ripple (in progress).
2) commit scripts.

But how do you make sure that every coin is worth exactly 1 USD ?

Every usdCoin is backed by a usd. This is the same if usdCoins are implemented through tainted satoshis, right?

To control the price, there would have to be an entity who controll the supply of the currency and the currency would essentially become centralized. There is no other way.

Who could be such issuer ?

A trust like the one sacarlson describes for beertokens.
An exchange (say mtgox) that wants to provide decentralized exchanges while still providing the service of "storing your dollars".
An association of businesses that doesn't want to rely on centralized exchanges. 

I'm a little late to the party but a bump can't hurt with this interesting thread anyway.

Maybe there is an alternative to a new chain as starting it is a little risky (51%), at least it would have to be merge mined.

Following "marked" satoshis should be possible with some rules.

Also with namecoin it would be possible to create all kinds of bonds: https://bitcointalk.org/index.php?topic=66868

With fiat bonds / fiat coins the issuer could simply take (part of) the interest he get's from the fiat money.

Also there are proprietary redeemable codes (gox).

Is this project still being developed?  I downloaded it and got it running and connected to two peers.  Is that the whole user base?

I never got this working...
 
Just a WoT running on Tor, I2P, freenet, or just some p2p network would be something...

Its a start at least; it needs users in order to learn what it does not have that would be nice to look into adding to it...

...It is massively configurable so just setting up all the transaction types or whatever that the users find they need is going to take some time and some users. It is GPL'd free open source so the time users put into working out how best it should be configured and so on won't be wasted as anyone else can run the same code if one or more sites using it vanish.

So please do come help figure out whether it is useful and how best to put it to use...

You could probably back it by redeeming for 1USD per coin with the usd in a bank vault somewhere.

"Exchanges" seem to have a somewhat biased view of trading, maybe, as looking at things like this thesis:

fiximulator.org/FIXimulator_Thesis.pdf

and looking at the whole "marketcetera" platform, and at the FIX protocol for equjities trading, and such sources, it reads a lot more like a vast world wide distributed network of traders, with to some extent a "buy side" where fund managers and such see things from their side, and a "sell side" where middlepeople such as stock exchanges try to find buy side folk looking to buy different things and match them up, partly presumably by means of the stuff some buyers are using as wealth to buy stuff with happens to be stuff that other folk are actually looking to buy.

Or something.

Certainly it is not "centralised", heck not only do some nations have more than one stock exchange but there are more and more nations that have at least one stock exchange.

Some of this stuff makes it seem like the so called stock exchanges are just gaggles / mobs of  sell-side folk ganging up the better to out-do the smaller sell-side folk..

I can connect to three peers now    It's a shame the app won't connect to Tor and I2p at the same time.  As a lot more people use Tor.  Is it still being developed this project    Does it make sense to still donate to the donation wallet address in the GitHub Wiki

Atomic trades could be possible using this software now with colored coins.

commits atleast 1 year old so no, mostly dead

I think the following factors lead to the failure of this p2p-exchange:
1) absence of raw internet version
2) weird development technology (should be c++/qt)
3) absence of internet site
4) no articles, video tutorials on yourtube
5) no promotion on blogs, news feeds, etc
6) absence of partner program (for established exchangers, who can accept wire transfers)
just compare it's marketing strategy with mtgox's one

Was this for real? I thought it was just an idea. LOL. A pitty, though.

How realtime market datafeeds are managed?

I like this idea. Centralised exchanges are a weakness in Bitcoin. I'll get reading and maybe get involved

[papaminer]

This is very good....

ALL MINERS SHOULD ALL USE THIS...

LEAVE EXCHANGES!!!!!!!

Hi all,

Don't get too enthusiastic yet. I've done some research today on p2p exchanges. Indeed, the dark exchange is brilliant. I've read all pages today. They do run into some trouble though: how can you make sure the dollars for the btc are transfered. And how do you do that decentralized? My conclusion, which I'm discussing with user "ConceptPending", is that there are p2p bitcoin exchange projects that solve this. Yes, there are other projects that have the same goal as this topic. One of them is p2px. It doesn't have any code yet but the concept is right. The other one is bitcoinx. It has code, a website, and an hour ago I decided to join them (I'm going to spend 2 months of fulltime coding). So don't forget to explore your options before joining anything!

Users will loose nothing in setting this up other than five minutes of there time.  As all actual BTC and fiat trading is done off the app.  This app just matches orders and could do with some development.  Although as shown by the (new) Ripple project unless the development can be monetised it's a lot less likely to happen.

Thanks for the heads-up I will check out p2px and bitcoinx but a dark/deepnet p2p exchange is the best option IMO especially as more alt-coins gain momentum.

Any interest in developing a decentralized marketplace, not an exchange. I.e. I can sell a fountain pen or keyboard on a P2P eBay system?
I developed for PlayerAuctions.com, and I want to create a decentralized marketplace. I.e. I'm a developer seeking link minders.

[leathan]

Not sure how this is going and have put 0 work into it but im curious? how is this going?

I thought superNET was the decentralized exchange?

Why not just use Open Bazaar and have a decentralized storefront?
