Open-UDC is based on TRM (Théorie Relative de la Monnaie, by Stéphane Laborde) and Universal Digital Currency project (UDC project), which aims to create a new digital currency based on individual members and the digital world.

"Develop a free system for money management between individuals, named Open-UDS.

Develop a free currency named Open-UDC, individuals based money with no emission center : based on a Universal Dividend/Universal Digital Income.

Open-UDS is the software system, and Open-UDC is the money with its creation rules."



"Open-UDS is the independant technological part of Open-UDC.

Open-UDC and Open-UDS system have been initially developped to allow members to exchange in a spirit of equity, digital goods and services in space (between members) and in time (between members and future members).

Each member of Universal Digital System community receives a monthly Universal Digital Income (UDI) described in the fourth and fifth rule of Open-UDC money issuance rules."




  • GNU Affero LGPL licence for Open-UDC


  • Open-UDC assumes that a free money, which allows each individual the liberty of producing, exchanging and undertaking, must be based on a Universal Dividend.


"Open-UDC go with a a progressive goal following three steps :

1) Implementation with centralised server

2) Implementation with hierarchical organisation

3) Implementation with P2P System"

Technical Rules

From: Open-UDC money issuance rules 1.0

"During initial phase, registration of new members in Universal Digital System community will feed the system with money creation, according to a strict parity with members. Fine tuning of Universal Digital Income / niversal Dividend paid monthly to all can therefore control overall system. Wise and prudent management over time of Universal Digital Income/Universal Dividend avoids both glut and scarcity of UDC money, based on minimum open and fixed relative growth rate as described in the fourth rule."

  • First Rule

“Open Universal Digital Currency (Open-UDC) is governed by democratic principles. Its members can decide to change the rules and evolution of the system in accordance with its basic principles.”

Money Rules will change only by a democratic decision based on majority of 2/3 or more of all members.

  • Second Rule

A new Open-UDC member must be approuved by 2/3 or more of all members

  • Third Rule

Open-UDC assumes a Universal Dividend money system (Universal Digital Income). That is to say that each individuals present and future community member, will create the same relative amount of money [ Relative means : Money created / (Monetary Mass / Individual)] during a long time period.

  • Fourth Rule

Open-UDC assumes a “ Pud = 1% / Month” of the “Monetary Mass / Individual” Universal Dividend amount as minimum amount of money created per individual.

Pud = minimal % of Universal Dividend (UD) growth

  • Fifth Rule

At the start of the Open-UDC system, the Universal Dividend start with an initiliazed amnount of 100 UDC / month / individual. Universal Dividend stay fix (in UDC amount) if Pud, the level of % growth decided in the 4th rule is not reached, and will be updated at that level when it will reach it.

So the full evolution is determined by :

- UD(0) = 100 UDC

- UD(n+1) = MAX { UD(n) ; Pud*M(n)/N(n) }

Where n is the past month. UD(n) is the UD of past month. Pud is the minimal % UD growth as defined in the 4th rule. M(n) is the existing monetary mass, and N(n) is the total amount of members. All are values just before calculation of new monthly UD(n+1)."


  • Sixth Rule

Universal Digital System must publish and update every month the following open data :

- Total amount of money (Monetary Mass) - nTotal number of members - Monetary Mass per member - Active amount of Universal Dividend in UDC - Active Universal Dividend in % / Month of Monetary Mass / Member - Minimum Universal Dividend as fixed in the fourth rule - Archive of those data for all months
