2  Bitcoin / Project Development / Goldcoin and Stablecoin proposals on: July 15, 2011, 08:08:05 PM
First, I don't think there is anything wrong with bitcoin. However, people have brought up the idea of "backing" bitcoin with gold or otherwise controlling deflation. I'm proposing two types of coins which could be created with a modified version of bitcoin (possibly multicoin: http://forum.bitcoin.org/index.php?topic=24209.0). One would be based on the price of gold, Goldcoin, and the other would be stable with little to no inflation or deflation, Stablecoin.

I would like to see them created. I do not want to see bitcoin changed in any way to support them. I think there are enough other bitcoin like currencies out there that the idea of yet another competing currency would not harm bitcoin in any way.

Both coin programs I'm proposing, would need to include the bitcoin like program, and an exchange. There is not currently an exchange attached to any version of bitcoin to my knowledge. I'm working on a distributed exchange outside bitcoin (https://github.com/macourtney/Dark-Exchange), and you could use a centralized exchange like MtGox or TradeHill, but that would defeat the decentralized aspect of a bitcoin like program. More work and though is needed in this area.

For now, I'm assuming there is both the bitcoin program and an exchange which can be queried for the current exchange rate.

Goldcoin

The purpose of Goldcoin is to create a bitcoin like coin which could be exchanged for a set amount of gold, let's say 1 Goldcoin equals 1 ounce of gold.

Besides a modified bitcoin program (I'm calling the Goldcoin program), we need an exchange. This exchange will only exchange Goldcoin with gold. The price is listed in ounces of gold, and the current price can be queried at any time.

You can mine Goldcoin, and there are transaction fees for sending Goldcoins. However, the transaction fee is not given to the miners directly. The transaction fee and mining award is adjusted to keep the price of Goldcoin as close to 1 Goldcoin equals 1 ounce of gold.

How does it work? The Goldcoin program watches the exchange for Goldcoin and does the following:

If the price of Goldcoin increases above 1 ounce of gold, the Goldcoin program increases the number of coins given as an award to the miners. Also, the transaction fee is lowered, possibly to 0. If 1 Goldcoin is trading for 1.1 ounces of gold, then the Goldcoin program can increase the mining award by 10% (maybe more) until the price of Goldcoin goes back to the target.

If the price of Goldcoin decreases below 1 ounce of gold, then the Goldcoin program decreases the number of coins given as an award to the miners. However, the award for mining can never go to 0 since that would cause all miners to quit. The transaction fees are raised. Any coins captured by transaction fees are not given to minors, instead they would be destroyed. With less Gold coins floating around, the price of Goldcoin should move back up to 1 ounce of gold.

Thus, without an authority (besides programming code), and without using actual gold as a backing, Goldcoin will tend toward 1 Goldcoin equals 1 ounce of gold.

Of course, it would not be perfectly stable with sudden interest causing the price to go up temporarily and loss of interest could bring it down. In either case, you can always assume if you wait long enough, the price will go back to the target price.

One last point. The exchange could use USD instead of gold, and since the price of gold in USD is well known, you could simply target the USD exchange to match the price of gold. You would then have exactly the same outcome as the gold exchange.

Using this method, you could create a coin targeted to almost anything. Which leads me to another coin:

Stablecoin

With Stablecoin, you have the same bitcoin like program and exchange as with Goldcoin with only a couple modifications.

The exchange is in USD. However, instead of targeting USD directly, we target a specific date. Let's say we use the date Stablecoin comes into existence. From then on, we keep track of how much USD has inflated/deflated using something like CPI or the Billion Price Index or even a combination of indices. If USD inflates say 1% we increase the target to $1.01 for one Stablecoin. On the other hand, if USD deflates by 1% we target $0.99 for one Stablecoin. Over time the increase and decreases would be added together to get some strange multiple as the target for Stablecoin.

The ultimate goal for Stablecoin would be to target a value not a price, and thus never inflate or deflate over time.

Stablecoin would be a great benefit to any merchant. They could simply price their goods and services in Stablecoin once, and never have to change the price again. They also know, no matter how long they hold Stablecoin, the value of Stablecoin would never increase or decrease significantly. If it does, they can wait until it makes it back to it's target.

Once Stablecoin is used to price goods and services online, you could then drop the use of CPI and Billion Price index and simply use a basket of goods priced in Stablecoin. If merchants start charging more or less on average for their goods, Stablecoin could adjust the number of coins accordingly.

Stablecoin could become the perfect currency for merchants. Which would make Stablecoin perfect for customers who want to buy from those merchants. Once enough merchants and customers adopt Stablecoin, everyone else would follow.

Making it happen

Unfortunately, I have my own bitcoin project to work on right now which is taking all of my time (did I mention Dark Exchange: https://github.com/macourtney/Dark-Exchange Smiley). However, I'm sure some goldbugs on this forum would be interested in the Goldcoin idea and take off with it (if you do, please make it open source).

I'm more interested in Stablecoin, and would be willing to put some time into building it. I just don't have the time right now.

Maybe one exchange could work for all of the targeted coin types. If the exchange could be built first (maybe Dark Exchange is that exchange), then I'll work on Stablecoin when I have more time.

Feedback

Please give me feedback on my two proposals. What works? What doesn't/can't work? What have I not thought through enough?

I'm not as interested in whether or not a gold based digital currency or a digital currency with no inflation or deflation is useful. By creating the currencies, they will be able to compete in the open market and the market will decide. I want to know if such coins could be created and how.

Any other feedback is welcome.
3  Bitcoin / Project Development / Dark Exchange: a 100% decentralized p2p exchange on: July 08, 2011, 01:07:34 PM
I'm starting a development topic for Dark Exchange here. The original post was in the Marketplace section, but a large number of issues have popped up and I don't think it's appropriate to discuss them there.

Here is the original thread: http://forum.bitcoin.org/index.php?topic=26063.0

TL;DR: https://github.com/macourtney/Dark-Exchange

You read that right! Dark Exchange is a 100% decentralized p2p exchange. No more worrying about exchange websites going down or locking your account. You now have complete control of your bitcoin exchanges and accounts.

Because Dark Exchange is decentralized, it can't work like Mt Gox or Trade Hill. Instead, it works more like bitcoin-otc and Bitcoin Market. You post offers and others accept them, or you can search all of the offers on the network and select the one you want. Dark Exchange will walk you through the process of completing a trade.

Advantages:

1. Dark Exchange can never be shutdown by anyone (including me) for any reason. As long as there are at least two nodes on the network, the exchange is up and running. (Actually this is more of a goal than a feature at this point. Though I tried to program it this way, I'm not sure if it will really stand up to real world use yet. But, that's why it's called Beta.)

2. No bitcoins or other money is held on a central server. You have complete control over your money the entire time.

3. Virtually all currencies and payment methods are supported. Any currencies or payment methods not already included can be added quickly.

4. No commissions. Free to use.

5. Open source. All source code for Dark Exchange can be found at: https://github.com/macourtney/Dark-Exchange

6. Runs on the I2P network. All connections are end to end encrypted, and privacy is under your control.


Dark Exchange is in Beta right now. Though I've run as many tests as I can think of on it, I'm sure it won't work exactly as advertised right now. I'm looking for intrepid people interested in helping me test Dark Exchange by using it.

All information on how to to download, install and use Dark Exchange can be found on the Dark Exchange wiki: https://github.com/macourtney/Dark-Exchange/wiki

If you have any troubles installing or using the exchange, let me know so I can start entering in issues to make Dark Exchange better.


And since it's the 4th.. Let's all declare independence from centralization with Dark Exchange!

Edit: I've released another version of Dark Exchange: https://github.com/macourtney/Dark-Exchange/downloads

The latest version is a full 1.0.0 release (out of beta). I still have a lot of work to do on it, but I wanted to stop incrementing the beta number and start using the preferred snapshot and multilevel version numbers. I'll add more info on the new release in a reply later in this thread.

Edit 2011-7-16 I've released another version (v1.1.1) of Dark Exchange.

Edit 2011-8-7 I've released another version (v1.2.0) of Dark Exchange.

6  Economy / Marketplace / I'm selling Reloadable Visa Debit cards for Bitcoin. on: January 05, 2011, 04:23:51 PM
I have a source for reloadable visa debit cards, and I'm willing to sell them and reload them for bitcoin.

Here's how it will work: You send me an agreed upon amount of bitcoin, and I will send you in the mail the debit card. When you want to reload your card in the future, simply send me more bitcoin and I'll refill your debit card.

The rates will be based on the Mt. Gox asking rate plus an additional percent to cover the cost of the card and refilling it.

Want to buy your groceries with bitcoin? Now you can! Want to buy pizza from your local restaurant with bitcoin? Now you can!

Finally, you can buy anything with bitcoin as long as the merchant accepts debit cards.

I set up a simple website for this service at: http://bitcoinmorpheus.tumblr.com/reloadable_debit_card_4_btc

Pm me for details or see the website for an alternative way to contact me.

8  Economy / Marketplace / Buy/Sell Mt. Gox USD for USD cash in the mail on: November 04, 2010, 01:23:07 AM
Hi all,

Since everyone seems to be having trouble getting cash in and out of Mt. Gox. I will start buying and selling Mt. Gox USD for cash in the mail.

I'm charging a low fee of 2% to buy Mt. Gox USD, and 2% plus $1 for postage to sell. Also, I'll have to limit the trades to $200 $500 per person per day for now. I may be able to raise the limits in the future.

I realize this forum says I'm a newbie, and you don't have a reason to trust me. However, I have been buying and selling bitcoin on Bitcoin Market and Mt. Gox for a few months now. If you've traded with me on Bitcoin Market, please vouch for me.

However, since I still may not have much trust on this board, I'll wave the 2% fee for my first $1000 in trades. That means 1:1 trades for Mt. Gox USD (minus $1 for withdrawals) for a limited time only.

PM me for details.
9  Economy / Marketplace / BTC -> Western Union USD on: September 01, 2010, 05:03:50 PM
Is anyone buying or selling BTC for Western Union transfers? What are the risks/restrictions involved?

I buy or sell BTC for USD by Western Union. Contact me for details. If it works out, I'll set up a website to simplify the exchange.
