Complementary-Currency on Open Source Currency

Stupid Currency Tricks: Group Currencies and Heroku

Wed, 03 Jun 2009 01:32:00 +0100

Like the last screencast, this one is a result of a feature request. About 9 months ago to the day, I met Johnny & Eva Barnett at Spiderhouse Coffee through Karen Gifford, a board member of ATEN. Johnny suggested a groups feature be added to oscurrency. This happened one week after Rich and I presented the idea of using insoshi for a currency server at One Web Day Austin and first started checking in code. Multiple improvements made to oscurrency have been a direct result of Johnny Barnett’s help.

Columbia Exchange Circle on KOMU TV

The Columbia Exchange Circle was on TV yesterday…

“The idea of the exchange circle is to connect community members and get people to share the skills and resources that they have in a way that does not rely on the current economy,” said Maggy Rhein, another organizer for the C.E.C.

And members say that taking the program online is the easiest way to connect.

“People can post the request and people can see it instantly,” said Vince Foley, another organizer for the group and the Web site manager.

Stupid Currency Tricks: Matching Unmet Needs with Available Resources

Fri, 10 Apr 2009 09:17:00 +0100

The previous five screencasts have been experimental. Anyone who knows Ruby on Rails can install the code and, since it is open source, anyone can make improvements to it. We have seen how the application programming interface (API) allowed for an independently developed killer app to be built. However, until today, to my knowledge, none of the new features shown in these “Stupid Currency Tricks” screencasts are actually enabled on real systems. Why? Because real people in real communities have not asked for them!

Stupid Currency Tricks: Identica

Tue, 10 Feb 2009 12:10:00 +0100

In the last screencast, requests were posted to Twitter and members were automatically followed when they associated their Twitter ID with their OSCurrency account. In this episode, we see how minimal changes to the code allow us to do the same with Identi.ca instead of Twitter.

Besides all the advantages of being open source, Identi.ca also accepts OpenID. So does OSCurrency (since it is derived from Insoshi). Wouldn’t it be great if microblogging messages could be routed like email messages?

Stupid Currency Tricks: Request Notifications with Twitter

Mon, 02 Feb 2009 12:43:00 +0100

Staying with the same theme as the previous screencasts, this one again shows how you don’t have to navigate back to the portal site to participate.

Sometimes requests are very time sensitive so it’s important to contact others ASAP about a need. This is a perfect application for Twitter or Identi.ca. When someone creates a request, either through the main website or through another site using the OsCurrency API, the request can immediately be sent out to Twitter.

QR Codes

Sat, 24 Jan 2009 23:15:00 +0100

Brandon Wiley invented an ATM machine this week for complementary currency using QR codes. Writing python code on Google App Engine, he wrote code which can generate a QR code using Google Chart API and an oauth consumer to allow someone to redeem the currency without giving the ATM site the username and password to their account. The transaction was made with the OSCurrency API. Some more API support needs to be done to make the transaction more resistant to counterfeiting, but it already makes a cool demo.

Stupid Currency Tricks with OAuth

Mon, 19 Jan 2009 09:31:00 +0100

We interrupt our regularly scheduled program with a screencast for software developers.

If you are not a software developer, the screencast may not be useful, but it’s good to understand why OAuth is critical to online complementary currency. When you buy something online, you don’t log into your bank’s website to do the transaction. You may click on a PayPal purchase button or some other one-click button. So, a member may not want to log into a community currency website to make a payment to a peer. The community currency website needs to expose an application programming interface to third party applications (like Facebook) to make payments and execute other functions. How is the third party authorized to make a payment on behalf of the member? The OAuth protocol allows a member to seamlessly grant the third party application authorization to perform specific actions on his accounts, for instance. It’s kind of a big deal.

OsCurrency Demo Site and Github Repository

Mon, 24 Nov 2008 23:15:00 +0100

At One Web Day Austin on September 22, the idea was offered (see video in previous entry) that it would be relatively straightforward to build a complementary currency system on Insoshi. Shortly after that, Rich and I began a new project in github. The latest code can be found in the edge branch of Oscurrency.

Two weeks ago, the Austin Time Exchange made the switch to running this code. Most of the changes you see in github since then are the result of feedback from the members. This site runs on one 256M slice on slicehost.

One Web Day Austin

Wed, 24 Sep 2008 03:09:00 +0100

We had the opportunity to talk about community currency at One Web Day. There is an archive of talks. It was neat to see Cafe Caffeine’s customers stop in for coffee throughout the evening and stay awhile to listen in on the compelling talks about privacy online and the war for peace. A big thanks to Jon Lebkowsky, Maggie Duval, Paul Walhus and Dusty Reagan for organizing a great event.

Contingencies

Fri, 09 Nov 2007 04:42:00 +0100

Last week, Rich and I gave a talk at OWASP Austin, the open web application security group. Social network security was the title. The main idea is how the health of social networks and communities can be compromised by attacking the identities - replacing identities known to the community with ones that are less functional. When identities are degraded or made more anonymous, then the community is at risk.

Of course, we talked about complementary currency and among RSnake’s several good questions was how does a complementary currency system keep someone from taking too much. Of course, we mentioned the idea of putting a credit limit for each person in the code, but as everybody knows, it is less about the code than it is about the people and if the community is healthy and all the transactions are transparent, then people will police it themselves. If the community is sick, they won’t. Even for the hackers at the OWASP meeting who are immersed in code every day, this idea seemed agreeable.

Solidarity Economy at USSF

Sat, 21 Jul 2007 01:03:00 +0100

Unfortunately, I haven’t blogged much on my experience at the US Social Forum. in short, it was great and I recommend attending any one you can get to. Hopefully Iĺl follow up on that statement. I have multiple social interests, so my time was divided. I also attended as part of a family vacation, so my attention was divided.

I took part in a workshop on Solidarity Economy. There were representatives from the US, Canada and Peru speaking about very active programs. Canada and Peru
have very developed programs worth learning about.

Almost a million Berkshares in circulation

Wed, 20 Jun 2007 13:35:00 +0100

There are about 844,000 BerkShares in circulation, worth $759,600 at the fixed exchange rate of 1 BerkShare to 90 U.S. cents, according to program organizers. The paper scrip is available in denominations of one, five, 10, 20 and 50.

In their 10 months of circulation, they’ve become a regular feature of the local economy. Businesses that accept BerkShares treat them interchangeably with dollars: a $1 cup of coffee sells for 1 BerkShare, a 10 percent discount for people paying in BerkShares.

Barcelona Time Banks on "The World"

Thu, 31 May 2007 02:09:00 +0100

PRI’s “The World” ran a great story on a Time Bank experience in Barcelona.

The World’s Gerry Hadden reports that a barter system is catching on in Barcelona, Spain. People register with what’s called a time bank to trade services. They might teach a language or do home repairs. The hours they work become time bank credits they can spend. Time banking saves people cash. And for many, it provides a sense of community.

Economia Solidária

I have trouble blogging frequently because I use to write fully researched articles and was called a journalist before bloggers came along.

Instead of infrequency, I think I’ll settle for short bursts like others do. This time, I’ll point out the remembrance that I understand Spanish and Portuguese. I often enjoy story that aren’t all over Slashdot, because they are all over barrapunto.com (the Spanish Slashdot). At some point a week ago, I ran into a Brazilian page, which led to Spanish pages. Outside of Venezuela, where Hugo Chavez is personally promoting community currencies, there is a very large community of people dealing in various kinds of social currencies. Some of them from banks dealing in national money as well.

Consensus and the Commons

Sun, 15 Apr 2007 18:14:00 +0100

In the Future of Ideas and Money and Lessig and Lietaer posts, a community currency is compared to the Internet. Both of them form an innovation commons.

Associated with community currency design is protocol. Contrast this with national money where laws generally regulate use.

Protocols on the Internet are generally established by the IETF. Jeanette Hofmann describes this process:

The IETF is open to anyone who is interested, provided they have the necessary technical competence and practical engineering skills. The exclusionary effect of this prerequisite should not be underestimated. The IETF has traditionally understood itself as an elite in the technical development of communication networks. Gestures of superiority and a dim view of other standardisation committees are matched by unmistakable impatience with incompetence in their own ranks.

Tangled Up in the Future - Lessig and Lietaer

Thu, 05 Apr 2007 05:14:00 +0100

This is a followup to The Future of Ideas and Money.

Bernard Lietaer reveals the difference between money and currency. What a central authority requires in payment of taxes, thereby imposing it as legal tender, is money. Taxes lock us into money. Money is the Yang. It promotes competition and scarcity created through hierarchy. Currency is whatever a community chooses as a means of payment, thereby accepting it as common tender. Social currency is the Yin.

The Future of Ideas and Money

Wed, 28 Mar 2007 05:55:00 +0100

Kellan suggested that some books are read better together and asks “Do you have favorite pairings?” Following Rich’s post on the Creative Commons, I’ve been thinking about Lessig’s The Future of Ideas and ever since the Naropa Workshop on Intentional Economics, I have thought it would be great to pair Lessig with Bernard Lietaer, author of The Future of Money.

I talked to Bernard about Lessig’s code/architecture as the fourth category of ways to regulate. When a complementary currency is introduced, does it merely fall in the economic incentive category or is it a lower level change to code and architecture?
