dear AM/Stacco, see: the infrastructure of the future, i.e. for sustainable and equitable production within planetary boundaries: open and shared supply chains + distributed ledgers + new accounting for contribution, flows in ecosystems of production, and matter/energy "Open source already means the cooperation and coordination of immaterial production at global scale, but in order to shift this model to physical production, it is necessary a particular kind of knowledge intermediation, i.e. accounting, and this is where the blockchain revolution comes in, by making possible global open and shared distributed ledgers where every transaction for physical goods can be verified. Accounting is at the core of civilization as it created the state system (the first writing found where ledgers in the Temple states of Sumer), while double entry book accounting, invented by Luca Pacioli, a Franciscan monk in 15th century Venice, sees the world in terms of the growth and accumulation of private assets, making possible the development of capitalism. Blockchain in this respect can be seen as making possible new forms of digital accounting that consist of ‘post-double-entry’ bookkeeping, namely: 1) open and contributive accounting (such as practiced by the Canadian Sensorica project), 2) REA (resource event action) ecosystem accounting, which let us see flows in shared circular economies involving multiple players and 3) biocapacity accounting, which is based on direct vision of the flows of matter and energy and therefore not only financially driven. Open shared ledgers are a key mutual coordination mechanism to shift open source coordination from software to manufacturing. This contributive accounting allows fairness, openness, transparency, security and environmental friendliness.
