Here are four five theses, which introduce P2P's special wiki section on Mutual Coordination Economics: 1. Today we have the emergence of a new proto-system of production, Commons-Based Peer Production in which contributors are free to contribute to a common pool of shareable knowledge, code and design. 2. This emerging new system of value creation and distribution is not sustainable if contributors need to find work as labour for capital. 3. To achieve this, we advocate the use of Commons-Based Reciprocity Licenses such as the Peer Production License. 4. The production of immaterial common pools is already regulated through mutual coordination and stigmergy, i.e. coordination based on open and transparent signals of what is needed by the system.
