A society organized around four coordination forms: kinship (+T), institutional hierarchy (+I), market exchange (+M), and the emergent form (+E). In David Ronfeldt’s TIME sequence, quadriform describes the coordination architecture that is not yet achieved but that the sequence points toward. Ronfeldt frames it as “the quadriformist option” and argues for pursuing it. The BioConomy is an attempt to build the architecture that makes the quadriform option operational.
Extended definition
Ronfeldt’s sequence runs from monoform (+T) to biform (+T+I) to triform (+T+I+M) and “potentially to quadriform” (+T+I+M+E). The qualifier is deliberate. Each prior transition took centuries, produced pathological intermediate forms, and was not guaranteed. The transition to quadriform is underway, Ronfeldt argues, but its outcome is not settled. It could stall at triform with a network overlay. It could produce a malformed fourth form captured by market logic (surveillance capitalism, platform monopoly). Or it could produce genuine quadriform coordination in which the fourth form operates with structural independence from the other three.
The “+E” in the quadriform combination is what the BioConomy corpus calls the Emergent form: coordination through pooled commitments toward outcomes no single actor can produce alone, organized at the scale of the watershed or bioregion. Ronfeldt floated renaming +N as +E in October 2025, with E standing for “equinets” or “exonets”; reading +E as Emergent is the corpus’s own extension. The substance of the renaming is that the fourth form is not simply networked communication, which the M form already uses extensively, but a qualitatively different coordination logic.
The quadriform option as the BioConomy’s structural claim
The BioConomy corpus takes Ronfeldt’s “quadriformist option” and gives it a specific institutional content. The claim is that genuine quadriform coordination requires four things the triform world does not yet have:
First, a coordination form that operates through pooled commitment at landscape scale, organized by bioregion. This is the BioHub and the commitment pool.
Second, a monetary substrate whose incentive logic is retention (through demurrage) rather than throughput (through interest). This is the bioregional currency described in the Emancipation Architecture.
Third, a mechanism that makes the +E form structurally independent of the +M substrate so that it does not default to triform with an overlay. This is what the (+T+I+M)^+N test diagnoses. The test asks whether the fourth-form coordination can persist when the +M substrate is removed. If it cannot, the system is triform, whatever its self-description.
Fourth, a transition pathway by which capital, land, and productive capacity cross from the +M regime into the +E regime. This is transvestment, operating through the Five Transvestment Pathways.
The BioConomy’s position is that these four elements together constitute the architecture of the quadriform option. Without any one of them, the fourth form collapses back into a triform overlay.
What quadriform coordination does not mean
Quadriform is not utopian. Ronfeldt is explicit that each form in the sequence carries pathologies, and the quadriform combination will carry its own. The T form’s pathology is tribalism in the pejorative sense (in-group exclusion). The I form’s pathology is authoritarianism. The M form’s pathology is predatory extraction. The E form’s pathology is not yet fully visible, but the corpus anticipates it in the form of governance capture by coordinating elites (the risk that BioHub coordinators become a new managerial class) and the risk of parochial bioregionalism (bioregions competing against one another for scarce ecological assets rather than coordinating at planetary scale).
Quadriform coordination means all four forms are active, each doing what it does well, and none capturing the others. Markets continue to coordinate allocative efficiency. Institutions continue to codify law and enforce contracts. Kinship networks continue to carry trust and identity. The E form adds the coordination of ecological function, landscape-scale restoration, and commons governance at a scale and with a structural independence that the other three forms cannot produce.

Provenance
Entry created 20 September 2026 as part of a four-entry set covering Ronfeldt’s coordination-form progression. The term “quadriform” and the framing of the “quadriformist option” are Ronfeldt’s. The four-element architecture (BioHub coordination, bioregional currency, the (+T+I+M)^+N test, and transvestment) that the BioConomy proposes as the content of the quadriform option is the author’s. The anticipated pathologies (coordinator capture, parochial bioregionalism) are the author’s structural inferences.
