Thought: there are two ways to get to decentralization — start with a center and fragment it (eg through forking or sharding or replication), or start with an atomized set and connect it up, being careful to avoid mechanisms like preferential attachment that cause hubs to emerge. Most decentralization is of the first type. You rarely see the second kind because multiple nodes have to get seeded independently with enough relatedness that network formation has an upside. In fact I can’t think of a single pure example. The closest might be shared causation. Eg many world mythologies have a flood myth, and one theory is all are cultural memories of the same global flooding event, like the last ice age melting or something.
