Polycentricity

The idea

Many formally independent decision centres with overlapping jurisdictions, taking each other into account, under an overarching system of rules. Its payoff is built-in self-correction: polycentric systems are "more likely than monocentric systems to provide incentives leading to self-organized, self-corrective institutional change" (Ostrom 1998, in Lewis & Aligica 2024, p. 3). Competition among overlapping providers generates error-correcting negative feedback as an unintended consequence (p. 4); Lewis & Aligica recast the whole architecture cybernetically as "countervailing controls based on multi-level feedback systems" whose capacity for self-governance is an emergent property (pp. 10–11). Overlap also carries information: what worked in one unit transmits to others, and larger systems back up failing small ones (fn. 14, p. 11).

Citation discipline: cite Lewis & Aligica 2024 (pp. 3–4, 10–11), McGinnis's guide (pp. 6–7), or Vincent Ostrom directly. Do NOT cite Digging Deeper — that chapter never treats polycentricity by name; its nearest passage is one paragraph on producer competition (Ostrom 2005/2025, p. 96).

The Nostr strain

Nostr is polycentric in structure — thousands of relay operators, client authors, list curators, no centre — but classical polycentricity assumes the centres interact: negotiation, contracting, mutual adjustment among authorities. Relay operators mostly never coordinate; the protocol itself is the coordination medium, replacing negotiated interaction with typed-event interoperability ({{ref:concept-governance-as-software|Governance as software}}). And the redundancy is uncoordinated: many actors independently solve the same exclusion problem in parallel layers, which is polycentric self-correction without the inter-centre bargaining the theory presumes ({{ref:claim-multiplicity-stack|Multiplicity}}). Whether protocol-mediated mutual adjustment still yields the self-corrective dividend is an open question — {{ref:q-does-competition-improve-governance|Q: Does interjurisdictional competition yield better governance?}}.
