Duniter is developing tools to create open currencies. A free money is built on 4 basic freedoms:
An individual is free to choose his currency
An individual is free to use the resources
An individual is free to produce added value
An individual is free to exchange using this open currency
The relative theory of money demonstrates that from these four basic freedoms, you can build a decentralized money. Each year, a universal dividend is co-produced by the participants.
A free currency is opening new perspectives for a free economy. http://en.duniter.org/faq
edit: OK I’ve updated the contributor image so now it displays Duniter logo (better than having me on each article). Facebook should be able to propose this image, but maybe you have to wait few hours to see the image in a facebook link.
