Bitcoin is a peer-to-peer digital currency. Peer-to-peer (P2P) means that there is no central authority to issue new money or keep track of transactions. Instead, these tasks are managed collectively by the nodes of the network. Advantages:

• Bitcoins can be sent easily through the Internet, without having to trust middlemen.
• Transactions are designed to be irreversible.
• Be safe from instability caused by fractional reserve banking and central banks. The limited inflation of the Bitcoin system’s money supply is distributed evenly (by CPU power) throughout the network, not monopolized by banks.

Bitcoin is an open source project currently in beta development stage. Development is hosted at SourceForge.

What's OPTIMAES?

OPTIMAES is an Open Project To Investigate Money And Economic Systems.

It consists of two things :

• agent based computer simulations to experiment with different economic systems
• this wiki which documents the experiments and the discussions around them

Why?

We wanted to help build a better world, and this seemed something we could do about it.

Building a better world is a political and contentious project. And it started to look to us as if economics (in the broadest sense), was the first key (of several) to unlock it. What you believe the economic facts to be will influence your political position. (Though for some people it maybe vice versa.) And understanding how economic systems work is a good way to start making some that work better. In particular, we were intrigued by Ideas That Were Being Advocated; by some feminists, ecologists and critics of globalization; for alternative economic systems such as InterestFreeMoney and GiftEconomies.

Although these sounded plausible (or at least interesting) we felt they could be tested. It's hard to get a pet country or community to experiment with, but as one of us was a programmer with some free time, we decided the next best thing was to do it in computer simulation. At least this would help us personally to get a handle on the issues. (We have enough hacker genes to conjecture that the best way to understand something is to build it; we also have holistic genes that doubt the conjecture; but genes don't fight, they collaborate.) Furthermore, other people might find it informative. And if these experiments did show some advantage in the alternative systems, that would be a good way to get them taken more seriously.

How does it work?

We're not claiming any kind of expertise here. This is a project that's born of our own ignorance of mainstream economics. But what we'd like, and think is possible, is to do some research openly, and to try to apply the collective intelligence of the internet to investigating this stuff. A smart-mob may just have the edge over current expertise. That's why this project is open for anyone to get involved with.

If you want to help out, an easy and valuable thing is to criticise. (See WeNeedYourCriticism) We know so little, that almost any intelligent comment you can make is going to be useful. And hopefully you can find an appropriate place to put the criticism on this wiki.

Another thing you can do is come up with new questions. Probably there are things you've always wondered about. Or deeply held economic / political beliefs you'd like to see demonstrated properly. After looking at the way this model works, you may be able to see how it can be adapted to answer your own questions. The code is freely available for you (under the GnuGeneralPublicLicense) to take and work from. Unlike some open source projects, we don't have a problem with forking into custom versions. If you develop your own project out of this, we can link to each other to get a conversation going.

You can also take existing experiments people have created and run them on your machine with a new parameter set. This isn't a SETI@Home type project which is about borrowing your processor time. Unless you want it to be. In which case it's easy. There's a tutorial called How To Do Real Useful Science In Just Five Minutes which shows you how to do that. It's also a good intro to the project in general.

Finally, if you know stuff that we don't, once again add it to this wiki. Links to other thinkers in this area are always welcomed.

And Remember

The results from these simulations are always provisional. If you think that they confirm your political position, remember that tomorrow, someone may come along with a refinement that shows things to be different. (See the DialogueOfModels)

Quoted from website:

[Regenerosity] "is a system for recognition of voluntary service, philanthropy & gift, civic engagement, trade, commerce, work, and any other contributions to the social capital and local economy of our communities. If you are a member of any community, whether as a person, as a non-profit organization, or as a for-profit business, there is something in it for you. As a person, you receive recognition for voluntarism, philanthropy, civic service, and many other types of community-building participation. As a non-profit organization, you receive tools for volunteer & donor recognition and access to untapped sources of support. As a for-profit business, you receive tools for customer loyalty & econometrics and access to untapped sources of working capital. As a school, you receive interactive tools for teaching economics & civics and for promoting community service. Everyone receives tools for measurement and analysis of social capital (their own and that of their communities) and practical tools to build community self-reliance and sustainable local economy, including community-based mutual credit systems.

Discover organization relations
Make more strategic donations
Promote more financial transparancy between different forms of (related) organizations

The motivation behind Donorge is to grow the ability to transparently support ideas and creation, either localized or connected around the world. What is supported inside Donorge is what you support and what in turn those ideas and creations you support support. This allows for there being more transparency and potential effectiveness at the resource layer of organizations and their voluntary contributed resources.
