Why we need to rethink monetary systems

If you are new to economy, you might first want to learn about how money is created in most of monetary systems.

Any Econ 101 course will do the trick.

For example, you may find the documentary "Money as a debt", by Paul Grignon, informative.

Libre currency is a new idea…

The idea of a Libre Currency originated in The Relative Theory of Money, a book written by french mathematician Stéphane Laborde in 2010.

…but more than just an idea !

It's more thant that!

A libre currency does exist.

It was launched in France on March, 8th 2017.

Its code name was originally Ğ1 and users now call it "jüne", or in phonetics: \ʒuːn\

1700 individuals create their Universal Dividen (UD) on a daily basis.

They use their Ğ1 to exchange goods and services, IRL or via plateforms surch as ğchange.

They use the Cesium app to send Ğ1 to each other.

Although the concept is difficult to explain to one's neighbough, the interest is increasing and the user base is steadily growing.

How we identify unique users

Since each member of the Ğ1 produces money, we had to find a way to make sure

The story behind The Relative Theory of Money

In 2008, in the eye of the storm of the subprimes crisis, engeneer, chess commentator and mathematician Stéphane Laborde got an interest for the stock market and macroeconomy.

He read, amongst many books, Agrarian Justice, a pamphlet written by Thomas Paine in 1797.

At that time, Bitcoin had just emerged, and lots of alternative currencies were beginning to appear in video games and such.

He saw in cryptocurrencies an opportunity to invent a monetary system that would have clear rules, based on humans beings and physics.

Money couldn't be a store of value, as Aristotle wanted, simply because value evolve through time, and one generation's way to think about value might be really different from the next.

Money should be, for each generation, a non-biased way to mesure exchange, just life the meter is a way to mesure distances.

Money should not be a way for bankers to decide what the world should look like.

The first libre currency is environemental-friendly!

Most cryptos tend to be high consummers of electricity.

They may even have a high carbon footprint, since a large part of the global electricity is produced by burning fossil fuels.

Bitcoin and Ethereum are disasters on the environemental part.

Ğ1 does not have these huge negative impacts, since we do not need the same Proof of Work Bitcoin and Ethereum do.

In Ğ1, only members of the Web of Trust (WOT) can verify transactions.

To take part in the verification of transactions, any member of the Web of Trust can install a Duniter node, that can run on a computer as small as a Raspberry Pi.
